Problems solved by technology

The laser opening mentioned in this application is only in terms of general laser drilling, that is, the laser is focused through a lens to form a high-energy beam, which is irradiated on the workpiece at one time, without precise positioning and software operating system. usually a dot
Moreover, it can only be used for punching workpieces with less precise positioning requirements, and is not suitable for workpieces such as high-performance honeycomb ceramic filter elements.
The holes of the honeycomb ceramic filter element are usually square holes, and there are hundreds of small square holes in one section. Due to the particularity of the ceramic production process, the size and position of the square holes in the section of the honeycomb ceramic filter are not exactly the same. Therefore, the general laser The spot punching method is first of all slow in operation, and more importantly, the laser beam may not be aimed at the hole of the honeycomb ceramic and hit the wall of the honeycomb ceramic, or it may miss punching, so that there is no hole in the hole. punch hole
This will seriously affect the subsequent process in the preparation process of the honeycomb ceramic filter element - the quality of plugging, especially the phenomenon of falling and / or leaking at the plugging place after drying and / or sintering of the product, which will affect the honeycomb. The product quality of the ceramic filter element ultimately affects the purification effect of diesel engine exhaust

Embodiment 1

[0031] As mentioned above, the hole cutting device provided by the present invention includes a laser system, an image recognition system, a turntable, an electric control system and a software system.

[0032] Wherein, the laser system is composed of a laser generator 7, a prism and a bracket (not shown in the figure). The laser beam emitted by the laser can change its direction by turning the prism.

[0033] 2. Image recognition system

[0034] Including CCD sensor, image processing circuit and other components. The position of the workpiece can be accurately captured and fed back to the computer, and the position of the marking graphic can be corrected through the software system.

[0035] 3. Turntable: It consists of feeding station 1, film installation station 2, camera station 3 and hole cutting station 4, each station is 90° apart, and the above three parts are placed on the workbench.

[0036] At camera station 3, the wall-flow honeycomb ceramic filter element to be...

Embodiment 2

[0038] 1) Fix the honeycomb ceramic filter element with a size of 35.62×35.78×255.50mm in the groove of the fixture bottom plate of the loading station.

[0039] 2) Press the "Start" button to make the turntable rotate to the film installation station at 1.5 seconds per station, and install the film;

[0040] 3) The turntable rotates to the CCD camera station, and the CCD starts to capture the hole position data of the honeycomb ceramic filter element;

[0041] 4) After the CCD is captured, the honeycomb ceramic filter element moves to the hole cutting station with the turntable, and the laser starts to cut holes and mark the end face of the filter element at intervals. In this way, the adjacent holes around each through hole are all blocked, and the adjacent holes around each blocked hole are all opened, which facilitates the smooth progress of the plugging process in the preparation process of the honeycomb ceramic filter element;

[0042] 5) After the marking is completed,...

Abstract

The invention relates to a laser hole-cutting device for a wall-flow type honeycomb ceramic filter core and a using method thereof, which are used for a precedent process, namely, laser hole-cutting, for preparing a honeycomb ceramic filter core plugging hole for a diesel engine particle catcher. The laser hole-cutting device mainly comprises a laser system, an image recognition system, a rotating disc, an electric control system, a software system, and the like; wherein a plurality of ceramic filter cores are simultaneously placed on a work bench and sequentially arranged in a laser hole-cutting work area through the rotation of the work bench. The using method comprises the following steps of: carrying out coarse positioning on a workpiece by using a clamp when a hole cutting machine works, then carrying out fine positioning by adopting the image recognition system, capturing precise positions of all holes as well as shapes and areas of the holes, rapidly analyzing data by using the electric control system and the software system, judging the hole positions that needs to be cut, and carrying out high-precision laser hole-cutting. The laser hole-cutting device is convenient to replace the ceramic filter cores, thereby being capable of realizing the automation and the continuity of the laser hole-cutting.

Description

technical field [0001] The present invention relates to a laser hole-cutting device, more specifically to a laser-cut hole-cutting device and its application method, which is the preceding process of "hole blocking" in the production process of a wall-flow honeycomb ceramic filter element. Background technique [0002] The wall-flow honeycomb ceramic filter element is mainly installed in the filtration and purification of diesel engine exhaust gas purification to capture carbon particles in the exhaust gas. The wall-flow honeycomb ceramic filter element is usually in the shape of a cuboid with parallel square channels along the axial direction. The pores of the filter element are not straight-through channels, but alternately block the two ends of the adjacent channels in its cross section, so that the exhaust gas of the diesel engine must pass through the inner porous thin wall to the adjacent channels before it can be discharged. When the exhaust gas passes through the po...
