[0026] See Figures 1 to 5 , a device for treating end face color difference of a silicon carbide honeycomb ceramic carrier of this utility model includes;
[0027] A conveying mechanism 100 for carrying and conveying a silicon carbide honeycomb ceramic carrier 1;
[0028] An end face color difference treatment mechanism 200, the end face color difference treatment mechanism 200 is arranged on the conveying mechanism 100. The end face color difference treatment mechanism 200 includes a laser dust removal protective cover 201. An opening 202 through which the silicon carbide honeycomb ceramic carrier 1 can pass is correspondingly arranged at the lower end of the laser dust removal protective cover 201. A laser generator 203 is arranged inside the laser dust removal protective cover 201. The silicon carbide honeycomb ceramic carrier 1 is conveyed by the conveying mechanism 100 and passes under the laser generator 203, and the end face is ablated by the laser emitted by the laser generator 203.
[0029] In the embodiment, the end face color difference processing mechanism 200 further includes a mounting bracket 204. The laser dust removal protective cover 201 is fixed on the mounting bracket 204. When the end face is laser ablated, strong light will be generated. To protect the operator's eyes, the laser dust removal protective cover 201 is added.
[0030] In the embodiment, the end face color difference processing mechanism 200 further includes a laser lifting device. The laser lifting device can drive the laser transmitter 203 to move up and down. The laser lifting device includes a lifting platform 205. The laser generator 203 is fixed on the lifting platform 205. A ball screw 206 is fixed on the mounting bracket 204. A screw nut 207 that mates with the ball screw 206 is provided on the ball screw 206. The screw nut 207 is fixedly connected to the lifting platform 205. The ball screw 206 is connected to a driving device. The ball screw 206 is driven by the driving device to drive the laser generator 203 to lift and lower. By adjusting the height between the laser generator 203 and the end face of the silicon carbide honeycomb ceramic carrier 1, the focal length is focused. In the embodiment, the driving device uses a runner 219. In other embodiments, a motor combined with a speed reducer can also be used to drive the ball screw. The function of the laser lifting device is to fix the laser generator on the lifting platform and adjust the height and focal length of the laser and the carrier end face up and down to adapt to carriers of different heights for ablation.
[0031] In the embodiment, in order to install the ball screw 206, deep groove ball bearings are installed on the mounting bracket. The ball screw 206 is inserted above the deep groove ball bearing 1, and the runner 219 is screwed into the lower end of the screw.
[0032] In the embodiment, in order to make the lifting of the laser generator 203 more stable, in the embodiment, a guide rail 208 is further provided on the column 2041 of the mounting bracket. A slider 209 that slidably mates with the guide rail 208 is provided on the guide rail 208. A cross beam 210 is provided at the lower end of the lifting platform 205. Both ends of the cross beam 210 are respectively fixed on the slider 209. Through the cooperation of the guide rail and the slider, the lifting stability of the lifting platform 205 is improved.
[0033] In an embodiment of the present utility model, a dust removal air duct interface 211 is further provided on the laser dust removal protective cover 201. The function of the laser dust removal protective cover is that when the end face is laser ablated, smoke and dust will be generated. The laser working area is sealed by the cover. A dust removal air duct interface is reserved on the cover for connecting an exhaust fan to suck away the smoke and dust generated by the laser, avoiding dust pollution to the staff, not only keeping the working environment clean, but also protecting the health of the operator and reducing the risk of occupational diseases.
[0034] In an embodiment of the present utility model, the laser dust removal protective cover further includes a front height adjustment baffle 212 and a rear height adjustment baffle 213. The front height adjustment baffle 212 is provided with bolt holes, and the rear height adjustment baffle 213 is correspondingly provided with vertically arranged oblong holes 214. The front height adjustment baffle 212 and the rear height adjustment baffle 213 are fixed together through bolts 218 and nuts in cooperation with the bolt holes and the oblong holes 214. The front height adjustment baffle 212 and the rear height adjustment baffle 213 can be adjusted in the height of the opening 202 through the cooperation of bolts 218 and nuts with the oblong holes 213, so as to adapt to silicon carbide honeycomb ceramic carriers 1 of different heights and avoid collisions between the silicon carbide honeycomb ceramic carriers 1 and the laser dust removal protective cover. The design of the front height adjustment baffle and the rear height adjustment baffle allows users to adjust the opening height according to the specific size of the carrier, enhancing the versatility and adaptability of the device.
[0035] In an embodiment of the present utility model, the laser dust removal protective cover 201 further includes an openable maintenance door 215. The maintenance door 215 is connected to the side wall of the laser dust removal protective cover through a hinge, and the maintenance door 215 is locked on the laser dust removal protective cover 201 through a lock 216. A door handle 217 is also provided on the maintenance door. By providing an openable maintenance door, it is convenient to adjust the height of the laser emitter and also convenient for maintaining and overhauling internal components.
[0036] In an embodiment of the present utility model, the conveying mechanism 100 adopts a metal chain conveyor belt. The role of the metal chain conveyor belt is to convey the carrier. The position of the laser generator remains unchanged. After emitting laser downward, the carrier can pass under the laser through the conveyor belt to ablate the entire end face. Since the afterglow of the laser will burn the conveyor belt, a metal chain plate is selected as the conveyor belt.
[0037] When the end face color difference treatment device of the silicon carbide honeycomb ceramic carrier in the embodiment is in use, first, through the laser generator lifting device, pull the door handle, and make the lifting platform move up and down by rotating the runner to adjust the height of the laser generator to achieve the purpose of focusing on the carrier. After the height is adjusted, close the maintenance door and lock the four locks, two on the upper and lower sides respectively, to lock the door tightly;
[0038] There are 3 oblong holes opened on the rear height adjustment baffle. The height of the baffle is adjusted up and down by adjusting the front and rear height adjustment baffles, and the lower end face is higher than the upper end face of the carrier;
[0039] Connect the dust removal fan hose in the workshop to the dust removal air duct interface and use a hoop to hold the hose tightly, so that the dust generated by laser ablation of the end face can be sucked away;
[0040] Place the carrier with color difference on the end face on the metal chain conveyor belt. After the carrier passes under the laser generator, the end face is ablated so that the entire end face of the carrier appears black. After one-sided ablation, the carrier is flipped 180° to ablate the other end face of the carrier. The overall efficiency is relatively high, and the one-sided ablation time is only 15 seconds;
[0041] After ablation, the entire end face of the carrier appears black. After ablation is completed, the adhesive seam of the carrier end face is re-striped for caulking treatment, and a carrier with a consistent end face color can be obtained to achieve the purpose of unifying the product factory consistency.
[0042] The end face color difference treatment device for silicon carbide honeycomb ceramic carriers in implementation can ensure that the end face colors of all silicon carbide honeycomb ceramic carriers uniformly appear black through laser ablation, effectively solve the problem of product shape consistency, significantly improve the overall quality and aesthetics of the product, with a one-sided treatment time of only 15 seconds, significantly improve production efficiency, reduce production costs, and make production more flexible by setting a laser lifting device and adjustable front and rear height adjustment baffles, which can adapt to silicon carbide honeycomb ceramic carriers of different sizes and shapes, bringing significant advantages and progress to the production of silicon carbide honeycomb ceramic carriers.
