Description

Technical Field

[0001] The utility model relates to the technical field of the production and application of honeycomb ceramic carriers, in particular to an end face caulking device for a silicon carbide honeycomb ceramic carrier. Background Technique

[0002] A silicon carbide honeycomb ceramic carrier is a porous ceramic material with a very high specific surface area and porosity, so it can be used as a carrier to carry various active substances such as catalysts and adsorbents. Honeycomb ceramic carriers are widely used in fields such as automotive exhaust purification, industrial waste gas treatment, and catalyst carriers. At present, due to the limitation of material properties, it is difficult to directly process the configuration dimensions required by the engine after-treatment system for silicon carbide honeycomb ceramic carriers, and later splicing is needed. The Chinese utility model patent with the publication number of CN220635097U discloses an auxiliary splicing device for a silicon carbide honeycomb ceramic carrier.

[0003] After the end face mud of the silicon carbide carrier is spliced and air-dried, it is easy to have the phenomenon of suction holes, resulting in pitted mud parts on the end face, which greatly affects the overall beauty of the carrier. At present, the caulking method is to cover a rectangular caulking paper above each bonding seam. A groove with a length of 100 mm and a width of 1-3 mm is opened in the middle of the caulking paper. The caulking paper is covered above the bonding seam, and the mud is picked up and pressed into the bonding seam with a scraper to fill the hollow places.

[0004] At present, there are 24 bonding seams on the end face of a conventional carrier. Since there will be misalignment between each bonding seam, the operator needs to perform manual caulking treatment on each bonding seam, and the production efficiency of the operation method is extremely low. And because the caulking paper is manually placed above the bonding seam and the mud is compacted into the bonding seam, it often happens that the mud is filled into the pore channels on the end face of the carrier due to the skew placement of the caulking paper, resulting in pollution of the pore channels and the need for rework to dig out the holes.

[0005] Moreover, since the widths of the spliced bonding seams are different, some are thick and some are thin, it is impossible to use the same width of caulking paper to caulk all the bonding seams on the end face. It is necessary to replace the caulking paper with different widths according to the width of the bonding seam in real time, with extremely low production efficiency and poor caulking effect. Content of the Utility Model

[0027] See Figures 1 to 4 , an end face caulking device for a silicon carbide honeycomb ceramic carrier in the embodiment of the present utility model, comprising:

[0028] A vision laser marking unit 100, the vision laser marking unit includes a camera 102 and a laser 103 located on a frame 101. The camera 102 is used to photograph the end face of the silicon carbide honeycomb ceramic carrier 1 with a transparent tape 2 adhered thereto, and the laser emits laser towards the adhesive seam 3 on the end face of the silicon carbide honeycomb ceramic carrier photographed by the camera, for burning through the transparent tape at the adhesive seam position to expose the adhesive seam 3;

[0029] An end face coating unit 200, for coating mud on the end face of the silicon carbide honeycomb ceramic carrier where the adhesive seam is burned out by the vision laser marking unit. The silicon carbide honeycomb ceramic carrier 1 with the burned-out adhesive seam can be seen at the position of the end face coating unit 200 in Figure 1 , 2 ;

[0030] An end face caulking unit 300, the end face caulking unit 301 includes:

[0031] A honeycomb carrier positioning mechanism, including a positioning table 301, for positioning the silicon carbide honeycomb ceramic carrier 1. The positioning table 301 is installed on a lifting device, and the lifting device can drive the positioning table 301 to lift;

[0032] A caulking scraping mechanism, the caulking scraping mechanism includes a scraping bottom plate 302 located at the upper end of the honeycomb carrier positioning mechanism. A carrier avoidance groove 303 for the silicon carbide honeycomb ceramic carrier 1 to expose is provided at the upper end of the scraping bottom plate 302. A scraper 304 is further provided at the upper end of the scraping bottom plate 302. The scraper 304 is connected with a driving device, and the driving device can drive the scraper 304 to push the mud into the adhesive seam 3 of the silicon carbide honeycomb ceramic carrier 1. In Figure 1 , 2At the rear side of the end face caulking unit 300, the silicon carbide honeycomb ceramic carrier 1 with caulking completed can be seen. For the caulking operation on the other end face, only repeat the whole process, and then remove the transparent tape 1 on the end face of the silicon carbide honeycomb ceramic carrier 1.

[0033] When the end face caulking device of the silicon carbide honeycomb ceramic carrier in the embodiment is in use, the silicon carbide honeycomb ceramic carrier 1 with the end face attached with the transparent tape can be placed in the vision laser marking unit 100. The vision laser marking unit can adopt existing mature vision laser marking equipment or vision laser welding equipment. However, when it is applied to the production of silicon carbide honeycomb ceramic carriers, the camera 102 uses a high-precision camera, which can accurately identify the caulking seams 3 on the end face of the silicon carbide honeycomb ceramic carrier 1. Then, an industrial-grade laser 103 is used to burn through the transparent tape at the caulking seam position according to the contour of the caulking seam 3, so that the caulking seam is exposed. The transparent tape remains on the positions of the cross-section of the silicon carbide honeycomb ceramic carrier 1 where there are no caulking seams.

[0034] Subsequently, through the end face coating unit 200, mud is coated on the end face of the silicon carbide honeycomb ceramic carrier 1 where the caulking seam has been burned out by the vision laser marking unit 100. In the embodiment, for the construction requirements of the end face coating unit 200, only mud needs to be coated on the end face of the silicon carbide honeycomb ceramic carrier 1 and it is not necessary to accurately cover the entire end face. The subsequent processing can be handed over to the end face caulking unit 300. The end face caulking unit 300 drives the scraper through a driving device to push the mud into the caulking seam 3 of the silicon carbide honeycomb ceramic carrier 1, and tears off the transparent tape attached to the carrier end face to complete the caulking. For the caulking operation on the other end face, only repeat the whole process. The end face caulking device in the embodiment is applicable not only to silicon carbide honeycomb ceramic carriers but also to other honeycomb ceramic carriers that need to be spliced.

[0035] Adopting the entire caulking process of the end face caulking device of the silicon carbide honeycomb ceramic carrier in the embodiment, from attaching the transparent tape on the end face of the silicon carbide honeycomb ceramic carrier, to laser-burning through the transparent tape at the caulking seam position, to finally the device driving the scraper to fill the caulking seam with the material, the time can be increased from the current 20 minutes of manual caulking to within 2 minutes. It not only improves the production speed but also greatly reduces the tediousness and error rate of manual operation. Workers do not need to be familiar with the caulking process, reducing the dependence on skilled labor and lowering the labor cost. During the whole caulking process, by attaching the transparent tape, the end face of the carrier is protected from being contaminated by the mud, ensuring the cleanliness of the carrier. In addition, since the vision laser marking unit 100 uses camera photography and laser-burning through the transparent tape, even if the thickness of the spliced caulking seams is inconsistent and the caulking seams are misaligned, it can be perfectly compatible and can also ensure the cleanliness of the carrier end face.

[0036] In an embodiment of the present utility model, a carrier base 400 may further be provided. A positioning cavity 401 matching the silicon carbide honeycomb ceramic carrier 1 is provided on the carrier base 400, and a positioning groove 320 matching the carrier base is provided on the positioning table 301. The setting of the carrier base 400 can facilitate the transfer of the silicon carbide honeycomb ceramic carrier 1 between various units and is convenient for construction.

[0037] In an embodiment of the present utility model, a carrier tape sticking unit 500 may further be provided for sticking a transparent tape 2 on the end face of the silicon carbide honeycomb ceramic carrier 1. The carrier tape sticking unit 500 may adopt a mounting device. Since the operations of less gap and beautiful joint in the subsequent process require time, the transparent tape 2 can also be stuck manually here; the end face coating unit 200 may adopt a mud supply device. The silicon carbide honeycomb ceramic carrier is placed below the mud supply device, and the mud supply device can apply the mud on the end face of the silicon carbide honeycomb ceramic carrier 1. Here, due to the low construction requirements and small construction workload, full manual operation can also be adopted, and there is no limitation here.

[0038] In an embodiment of the present utility model, the driving device in the end face joint beautifying unit 300 includes a lateral displacement device and a longitudinal displacement device 306. The longitudinal displacement device 306 can drive the squeegee 304 to move to a position flush with the scraping bottom plate 302. The scraping bottom plate 302 may adopt a plate member with a relatively high smoothness, such as a stainless steel plate or other metal plates. The lateral displacement device can drive the squeegee to push the mud into the adhesive joint of the silicon carbide honeycomb ceramic carrier.

[0039] In the embodiment, the lateral displacement device includes a bench 305 installed at the upper end of the scraping bottom plate 302. A rodless cylinder 307 arranged horizontally is installed on the bench 305. The lower end of the moving part of the rodless cylinder 307 is installed with a sliding plate 308. The lower end of the sliding plate 308 is installed with a longitudinal displacement device 306. The longitudinal displacement device 306 may adopt a linear displacement device such as a cylinder or an oil cylinder. The squeegee 304 is installed on the longitudinal displacement device 304. Slide rails 309 are respectively arranged on both sides of the bench 308, and sliders 310 are arranged at the lower end of the sliding plate 308. The slide rails 309 are in sliding fit with the sliders 310.

[0040] In the embodiment, a plurality of longitudinal displacement devices are arranged at the lower end of the sliding plate. The squeegee includes a first squeegee 301A and a second squeegee 304B. The first squeegee 301A and the second squeegee 304B are separately arranged on both sides, and the orientations of the first squeegee 301A and the second squeegee 304B are opposite. The settings of the first squeegee 301A and the second squeegee 304B can make the joint beautifying efficiency of the end face joint beautifying unit 300 higher.

[0041] When using the end face caulking unit 300, first, through the lifting device, lift the silicon carbide honeycomb ceramic carrier 1 on the lifting device until it protrudes from the carrier avoidance groove 303 and is flush with the scraping bottom plate 302. First, drive the longitudinal displacement device 306 on one side to lower the first scraper 301A until it is flush with the scraping bottom plate 302. Subsequently, the transverse displacement device drives the sliding plate 308 to move for scraping and caulking. After the sliding plate moves in place, the first scraper 301A is lifted upward, and the second scraper 304B moves downward to be flush with the scraping panel. The transverse displacement device drives the sliding plate 308 to move in the reverse direction for scraping and caulking again. Repeating such reciprocating motion about 2 times can scrape the mud into the bonding seam 3, and the reciprocating motion of the first scraper 301A and the second scraper 304B compacts the mud into the bonding seam to ensure the caulking effect.

[0042] See Figure 4 , in one embodiment, a scraper angle adjustment mechanism is installed on the moving part of the longitudinal displacement device 306. The scraper angle adjustment mechanism includes a fixed block 311 fixed on the moving part of the longitudinal displacement device 306. The fixed block 311 is connected to the moving block 313 through a scraper angle adjustment shaft 312. The moving block 313 and the fixed block 311 are respectively fixed to the scraper angle adjustment shaft 312 through locking pins 314. The scraper 304 is installed on the moving block 313 through a scraper fixing plate 315 and bolts. Through the design of adjustable scraper angle, the versatility of the equipment can be improved.

[0043] In one embodiment, the visual laser marking unit 100 further includes a surrounding plate 104 installed on the frame. The surrounding plate 104 encloses a protective cover, and the camera 101 and the laser 102 are installed in the protective cover 104 to avoid being damaged.

[0044] In one embodiment, the lifting device includes a cylinder 316. A plurality of guide posts 317 and guide sleeves 318 are arranged on the outside of the cylinder 316 for guiding cooperation. A buffer pad 321 is further arranged at the lower end of the positioning table 301.

[0045] In one embodiment, baffles 319 are respectively arranged on both sides of the carrier avoidance groove 303 on the scraping bottom plate 302. The arrangement of the baffles 319 can prevent the mud from falling off the scraping bottom plate 302.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
