[0035] like Figure 1-8 As shown, in this embodiment, the microporous honeycomb assembly and laser welding equipment includes a frame 1; and a traction mechanism 2 arranged on the frame 1, such as Figure 2-3 As shown, the traction mechanism 2 includes a support plate 21 for supporting the honeycomb material strip 7, and a clamping claw 22 for clamping the head of the honeycomb material strip is provided at the front end of the support plate 21. The support plate 21 can be driven by a first driving member 23 provided on the frame 1 to move the honeycomb material strip along its length direction, and the clamping claw 22 can be driven by a second driving member 24 provided on the support plate 21 to deflect the honeycomb material strip on the support plate 21 along its thickness direction;

[0036] And a limiting mechanism 3 arranged on the frame 1, such as Figure 4 As shown, the limiting mechanism 3 includes a left limiting member 31 and a right limiting member 32 arranged on the left and right sides of the honeycomb material strip, and the left limiting member 31 and the right limiting member 32 can be driven to be relatively close or far away by a third driving member 33 and a fourth driving member 34 arranged on the frame 1, respectively. When the left limiting member 31 and the right limiting member 32 are close to each other, a limiting channel 35 can be formed on the support plate 21 to just limit the pre-assembly of the honeycomb material strip;

[0037] And the welding tool 4 arranged on the frame 1, such as Figure 4 As shown, the welding tool 4 is arranged on the front side of the left limiting member 31 or the right limiting member 32, so that the honeycomb material strip can be welded while being pulled out and moved from the limiting channel 35.

[0038] Working principle: When starting to produce microporous honeycombs, first put two honeycomb material strips 7 between the left limiter 31 and the right limiter 32; then first clamp the head of the honeycomb material strip through the clamping jaw 22, and then drive the two to approach each other through the third driving member 33 and the fourth driving member 34, so that the honeycomb material strip 7 is limited and matched to pre-assemble a honeycomb column; then move it with the action of the clamping jaw 22 and the support plate, and start the welding tool while moving to achieve welding while moving; when the honeycomb column is welded, the support plate stops, and then the honeycomb column is offset from the welding line under the action of the second driving member 24. During the offset process, the left limiter 31 and the right limiter 32 move relatively far away from each other so that the honeycomb column can return smoothly; after returning to the initial welding position under the action of the first driving member 23, the clamping jaw 22 releases the welded honeycomb column, and at the same time takes a new honeycomb material strip to match the honeycomb column, and repeats the above operation until a microporous honeycomb of a set thickness is produced. The supplement of the honeycomb material strip can be, but is not limited to, achieved manually.

[0039] In one embodiment, in order to prevent the left stopper 31 and the right stopper 32 from causing the honeycomb strip to deform due to overpressure when the honeycomb strip is limited, a positioning mechanism 5 can be provided on the frame, such as Figure 5-6 As shown, it specifically includes a parallel transmission chain 51 and a positioning track 52, the positioning track 52 is arranged above the limiting channel 35, and a plurality of positioning members 53 are connected along the length direction of the transmission chain 51 on one side close to the positioning track 52, the positioning member 53 includes a slide 531, one end of the slide 531 can cooperate with the positioning track 52 so that it can move along the positioning track 52 with the transmission chain 51, and the other end is connected with a positioning needle 532, and the distance between adjacent positioning needles is an integer multiple of the distance between adjacent micro-holes, so that some of the positioning needles 532 that move synchronously with the honeycomb material belt can enter the limiting channel 35 and cooperate with the micro-holes formed by splicing the honeycomb material belt 7.

[0040] When the two honeycomb material strips are limited and spliced, the partial positioning pins 532 at the bottom of the positioning track 52 are just limited in some micro-holes, so as to better support the honeycomb material strips and make them quickly and accurately spliced. When the honeycomb material strips are clamped, pulled and moved for welding, the conveyor chain 51 that moves synchronously with it moves with the positioning parts 53. When the initial partial positioning pins 532 can be positioned to the rear end of the honeycomb material strip, the front positioning pins 43 will move out of the micro-holes in sequence with the moving welding; when the initial partial positioning pins 532 cannot be positioned to the rear end of the honeycomb material strip, the front positioning pins 532 will move out of the micro-holes in sequence with the moving welding, and new positioning pins 532 at the rear will enter the micro-holes in sequence, so that the honeycomb material strips are always supported when they are in the limited and spliced ​​position.

[0041] Furthermore, in order to better achieve the depth coordination between the positioning pin and the microhole, the positioning pin 532 is connected to the slide seat 531 through the hinge shaft 533, and the hinge shaft 533 is parallel to the chain axis of the conveying chain. In this way, when the positioning pin 532 rotates to the lower part of the positioning track, it can move vertically into the microhole to achieve the depth coordination between the two, and vice versa when moving out.

[0042] Furthermore, the bottom of the positioning track 52 is composed of a straight track section in the middle and inclined track sections on both sides thereof. With such a configuration, the positioning member 53 can transition to the straight track section more stably, and the straight track section can cooperate with multiple positioning members 53 at the same time to position multiple microholes.

[0043] Furthermore, the positioning mechanism 5 is arranged on the frame 1 via a mounting frame 6 .

[0044] Furthermore, the fourth driving member 34 is disposed between the mounting frame 6 and the frame 1, the positioning track 52 is suspended above the limiting channel 35 through a rib plate 54 fixed to the top of the mounting frame 6, and the transmission chain 51 is suspended on one side of the positioning track 52 through a driving wheel 55 and a driven wheel 56 disposed on the top of the mounting frame 6. The driving wheel is specifically driven by a driving member, which can be a pulley drive or a direct motor drive. As for the mounting frame, its bottom does not contact the support plate part,

[0045] Furthermore, the structures of the fourth driving member 34 and the third driving member 33 are as follows: Figure 4 and 8 As shown, the third driving member 33 specifically includes two left slide rails fixedly connected to the frame, each left slide rail is provided with a left slide seat, the top of the two left slide seats is fixedly connected with a left connecting plate, the left limit member is connected to the left connecting plate, the bottom of the left connecting plate is fixedly connected with a left limit block, the left limit block is connected with a left lead screw, and the left lead screw is driven by a left motor provided on the frame to drive the left limit member to move left or right when needed. The top of the left connecting plate is a storage platform, which can be used to place the honeycomb material strips to be used, so as to facilitate the production personnel to select new honeycomb material strips for splicing as needed. Figure 8 As shown, the fourth driving member 34 specifically includes a right motor, a right lead screw, a right limit block, and two groups of right slide seats and right slide rails. At least two groups of right slide seats and right slide rails are arranged between the mounting frame and the right limit member to enable the right limit member to slide relative to the mounting frame; the right limit block is fixedly connected to the right limit member, the right lead screw is threadedly matched with the right limit block, and the right lead screw can be driven by the right motor fixed on the frame to drive the right limit member to move left or right when necessary. Although the above structure is not specifically shown in detail by the drawings, it is sufficient for ordinary technicians in this field to understand how the above structure is set according to the above description combined with the drawings.

[0046] Regarding the structures of the first driving member 23 and the second driving member 24, one of them is specifically as follows: Figure 2-3 As shown, the first driving member 23 includes a first lead screw rotatably arranged on the frame 1, a first slide rail 231 is arranged on the side of the first lead screw, the lower part of the support plate 21 is threadedly matched with the first lead screw and slidably arranged with the first slide rail 231, so that the first lead screw can be driven to rotate by a first motor 232 arranged on the frame 1 to drive the support plate 21 to move. The second driving member 24 includes a fixed seat 241 fixed to the support plate 21, a second slide rail 242 is arranged on the fixed seat 241, a slide seat 243 is arranged on the second slide rail 242, the clamping member 22 is fixed to the slide seat 243, a lead screw is connected between the fixed seat 241 and the slide seat 243, and the lead screw is connected to the second motor through a worm gear structure to drive the slide seat to move along the second slide rail.

[0047] In one embodiment, if Figure 5 As shown, the clamping jaw 22 includes two clamping jaws arranged on the left and right, and a welding port 221 extending to the clamping end thereof is provided on the clamping jaw arranged near the welding tool 4. The welding tool 4 is arranged on one side of the welding port at the initial welding position, and laser welding can be performed through the welding port 221. If the head of the honeycomb material strip is clamped at the position of the welding port 221, the welding of the honeycomb material strip can be realized from the beginning without being affected by the clamping of the servo clamping jaws.

[0048] Further, such as Figure 5 As shown, the inner side of the clamping jaw is provided with an upper clamping protrusion 222 and a lower clamping protrusion 223 that can match the shape of the honeycomb material strip, and the welding port 221 is provided between the upper clamping protrusion 222 and the lower clamping protrusion 223. In this way, the concave and convex parts can match with the honeycomb material strip 3, so as to tightly clamp a number of honeycomb material strips. The clamping jaw 22 can specifically adopt a servo clamping jaw.

[0049] In one embodiment, if Figure 7 As shown, the left limiting member 31 and the right limiting member 32 are provided with an upper limit convex portion 311 and a lower limit convex portion 312 on the inner sides thereof. Such a configuration can reduce the contact area on the basis of better limiting the honeycomb material strip, so that it is convenient to be pulled out for welding. In addition, the upper limit convex portion 311 and the lower limit convex portion 312 are both arc-shaped convex portions, so that the honeycomb material strip can be pulled out and moved more smoothly on the basis of being limited, so as to smoothly realize subsequent welding. The left limiting member 31 and the right limiting member 32 can specifically adopt a limiting plate respectively.

[0050] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0051] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
