[0050] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In some descriptions of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0051] The present application provides a material beating mechanism which can be used for beating the cut material to completely separate the product from the material.

[0052] Referring to Figure 1 A material beating mechanism includes a base 110, a first driving assembly 120, a second driving assembly 130 and a material beating assembly 140. The first driving assembly 120 is drivingly connected with the base 110 to drive the base 110 to move in a first direction. The second driving assembly 130 is disposed on the base 110 to move with the base 110 in the first direction. The material beating assembly 140 includes a fixing structure 141 and a material beating structure 142. The fixing structure 141 is disposed on the base 110, and the material beating structure 142 is located on one side of the fixing structure 141. The second driving assembly 130 is drivingly connected with the material beating structure 142 to drive the material beating structure 142 to move in the first direction.

[0053] Specifically, the first driving assembly 120 can drive the second driving assembly 130 and the fixing structure 141 to move synchronously along the first direction through the base 110, so that the fixing structure 141 can act on the product cut from the material sheet, and the product can be fixed. At the same time, since the second driving assembly 130 is drivingly connected with the material beating structure 142, the material beating structure 142 can also move along the first direction by a certain distance, and when the fixing structure 141 fixes the product, since the material beating structure 142 is located on one side of the fixing structure 141, when the second driving assembly 130 continues to drive the material beating structure 142 to move along the first direction, the material beating structure 142 can act on the material sheet around the product, and the material sheet can be pressed down, so that the product is separated from the material sheet.

[0054] That is, in the material beating mechanism 100, the first driving assembly 120 can drive the fixing structure 141 to move along the first direction to contact the product on the material sheet and fix the product through the base 110, and at the same time, then the second driving assembly 130 and the drivingly connected material beating structure 142 can also move along the first direction to approach the material sheet under the action of the base 110, when the fixing structure 141 fixes the product, the second driving assembly 130 continues to drive the material beating structure 142 to move along the first direction, so that the material beating structure 142 acts on the material sheet around the product and presses the material sheet along the first direction, so that the product is separated from the material sheet. This way can avoid damaging the product when the product is separated from the material sheet.

[0055] Further, the fixing structure 141 can be provided with suction holes 1411. It can be understood that when the fixing structure 141 approaches the product along the first direction, the suction holes 1411 can adsorb the product, avoid the product from being displaced when the material beating structure 142 beats the material sheet, and can avoid the relative movement between the product and the fixing structure 141, so as to avoid the product from being damaged by the fixing structure 141.

[0056] Specifically, in an embodiment, the fixing structure 141 can include a mounting seat 1412 and a plurality of fixing columns 1413, the mounting seat 1412 is arranged on the base 110, and the plurality of fixing columns 1413 are connected with the mounting seat 1412, and each fixing column 1413 is provided with a suction hole 1411.

[0057] It can be understood that when the material sheet needs to be cut into a plurality of products, each fixing column 1413 on the mounting seat 1412 can act on the corresponding product, so as to fix each product. When each fixing column 1413 is respectively provided with a suction hole 1411, the fixing column 1413 can fix the product through the suction hole 1411.

[0058] Further, in order to conveniently introduce negative pressure gas into the adsorption holes 1411 on each fixed column 1413, a negative pressure cavity can be arranged in the mounting seat 1412, and the negative pressure cavity is in communication with the adsorption holes 1411.

[0059] It can be understood that, by arranging the negative pressure cavity (not shown in the figure) in the mounting seat 1412, negative pressure is generated in the negative pressure cavity, so that the adsorption holes 1411 on each fixed column 1413 can generate negative pressure, thereby adsorbing the product.

[0060] Referring to Figure 2 , the material knocking structure 142 can include a connecting seat 1421 and a material knocking head 1422, the second driving assembly 130 is in driving connection with the connecting seat 1421, the connecting seat 1421 is provided with a first avoiding hole 1423 avoiding the fixed column 1413, and the material knocking head 1422 is arranged on the connecting seat 1421 at the side of the first avoiding hole 1423.

[0061] Specifically, the second driving assembly 130 can drive the connecting seat 1421 to move along the first direction and act on the material sheet, and press downward along the first direction to make the material sheet separate from the product, and the first avoiding hole 1423 can avoid the fixed column 1413 when the connecting seat 1421 moves, and the first avoiding hole 1423 can conveniently arrange the material knocking head 1422 on the connecting seat 1421 at the side of the fixed column 1413.

[0062] Further, in order to facilitate the movement of the connecting seat 1421 driven by the second driving assembly 130, and to avoid interference between the connecting seat 1421 and the mounting seat 1412, the material knocking structure 142 can further include a first transmission member 1424, the connecting seat 1421 is located at the end side of the mounting seat 1412 connected to the fixed seat, and the second driving assembly 130 is in transmission connection with the connecting seat 1421 through the first transmission member 1424. Specifically, the second driving assembly 130 drives the connecting seat 1421 to move along the first direction through the first transmission member 1424.

[0063] Further, in order to facilitate the arrangement of the first transmission member 1424, a second avoiding hole 1414 can be arranged on the mounting seat 1412, and the first transmission member 1424 is movably arranged in the second avoiding hole 1414. It can be understood that, the second avoiding hole 1414 can avoid the first transmission member 1424 when the first transmission member 1424 moves, thereby facilitating the arrangement of the first transmission member 1424, and the first transmission member 1424 arranged in the second avoiding hole 1414 can improve the stability of the movement of the first transmission member 1424.

[0064] Referring to Figure 1In an embodiment, in the case that the moving stroke of the second driving assembly 130 is not adjustable, in order to adjust the height of the material hitting head 1422, the material hitting structure 142 further comprises an elastic member 1425 and a second transmission member 1426. The first transmission member 1424 is provided with a stopper 1427 at an end away from the connecting seat 1421. The elastic member 1425 is sleeved on the first transmission member 1424, and one end of the elastic member 1425 abuts against the mounting seat 1412, and the other end of the elastic member 1425 abuts against the stopper 1427. One end of the second transmission member 1426 abuts against the end of the first transmission member 1424 away from the mounting seat 1412, and the other end of the second transmission member 1426 is arranged on the second driving assembly 130, and the second transmission member 1426 is adjustable in the first direction on the second driving assembly 130.

[0065] For example, the second transmission member 1426 can be connected with the second driving assembly 130 through an adjusting bolt. By adjusting the adjusting bolt, the second transmission member 1426 can be moved in the first direction, so as to adjust the position of the second transmission member 1426 in the first direction.

[0066] It can be understood that the first transmission member 1424 elastically abuts against the second transmission member 1426 through the elastic member 1425. Therefore, by adjusting the position of the second transmission member 1426 in the first direction, the position of the first transmission member 1424 in the first direction can be adjusted, so as to adjust the position of the material hitting head 1422 connected with the first transmission member 1424 in the first direction.

[0067] When the material hitting head 1422 hits the material sheet, the second driving assembly 130 drives the second transmission member 1426 to move, the second transmission member 1426 drives the first transmission member 1424 to move, so that the material hitting head 1422 on the connecting seat 1421 can move. After the second driving assembly 130 drives the second transmission member 1426 to return to the initial position, the first transmission member 1424 can return to the initial position under the action of the elastic member 1425, and the abutting state between the first transmission member 1424 and the second transmission member 1426 is maintained, so that the material hitting head 1422 returns to the initial position.

[0068] Further, in an embodiment, a shaft sleeve (not marked in the figure) can be further arranged in the second avoiding hole 1414. The first transmission member 1424 is in sliding connection with the shaft sleeve, and the shaft sleeve can improve the stability of the movement of the first transmission member 1424.

[0069] In an embodiment, the material-punching structure 142 can further include a third transmission member 1428, the second driving assembly 130 is in transmission connection with the third transmission member 1428, the second transmission member 1426 is connected with the third transmission member 1428, and the second transmission member 1426 is adjustable on the third transmission member 1428 in the first direction. It can be understood that the third transmission member 1428 can facilitate the adjustable connection between the second transmission member 1426 and the second driving assembly 130.

[0070] In the above embodiment, the first driving assembly 120 can be a motor, and the second driving assembly 130 can be a pneumatic cylinder.

[0071] Referring to Figure 3 and Figure 4 The application further provides a laser cutting device, which includes a first workbench 200, a laser cutting mechanism 300, a first displacement mechanism 400, and the material-punching mechanism 100 in the embodiment. The laser cutting mechanism 300 is arranged opposite to the first workbench 200, and is used for cutting the material sheet on the first workbench 200. The first displacement mechanism 400 is in driving connection with the first driving assembly 120 of the material-punching mechanism 100, so that the fixing structure 141 and the material-punching structure 142 can be located above the first workbench 200. Thus, the fixing structure 141 can fix the product formed by cutting the material sheet on the first workbench 200, and the material-punching structure 142 can punch the material sheet.

[0072] Further, in an embodiment, the laser cutting device can further include a rotary driving mechanism 500, which is in driving connection with the first workbench 200, so that the first workbench 200 can rotate, and thus the material sheet on the first workbench 200 can rotate from below the laser cutting mechanism 300 to below the material-punching mechanism 100. It can be understood that the above structure can facilitate the laser cutting mechanism 300 to cut the material sheet on the first workbench 200, and also facilitate the first displacement mechanism 400 to drive the fixing structure 141 and the material-punching structure 142 to move to above the first workbench 200. The rotary driving mechanism 500 can be a rotary driving platform, and the first displacement mechanism 400 can be a lead screw motor.

[0073] For example, the first displacement mechanism 400 can drive the first driving assembly 120 to move in the second direction, so that the first driving assembly 120 drives the material-punching mechanism 100 to move in the second direction, and thus the fixing structure 141 and the material-punching structure 142 can move to above the first workbench 200. The first direction is perpendicular to the second direction.

[0074] Referring to Figure 3 and Figure 4The laser cutting device can further comprise a first jig 600 and a turnover driving mechanism 700, the turnover driving mechanism 700 is arranged on the first workbench 200, the turnover driving mechanism 700 is drivingly connected with the first jig 600, so that the first jig 600 can be turned over, and the first jig 600 is used for fixing the material sheet.

[0075] Specifically, after the laser cutting mechanism 300 cuts the material sheet on the first jig 600 and the material beating mechanism 100 beats the material sheet on the first jig 600, dust or waste and the like can be generated on the first jig 600. At this time, the turnover driving mechanism 700 can drive the first jig 600 to turn over, so that the first jig 600 is inclined, so that the dust or waste and the like on the first jig 600 can slide off. The turnover driving mechanism 700 can be a rotary air cylinder.

[0076] Referring to Figure 3 and Figure 5 , the laser cutting device can further comprise a waste box 800, the waste box 800 is arranged below the first workbench 200, so as to receive the waste falling after the jig is turned over.

[0077] In an embodiment, the waste box 800 can be provided with two, one waste box 800 can be located below the material sheet cutting station of the first workbench 200, and the other waste box 800 can be located below the material beating station of the first workbench 200.

[0078] Referring to Figure 4 , the laser cutting device can further comprise a second workbench 900 and a material turning mechanism 1000, the first displacement mechanism 400 is drivingly connected with the material turning mechanism 1000, the second workbench 900 is located on one side of the first workbench 200 and on the moving path of the material turning mechanism 1000. For example, in an embodiment, the first displacement mechanism 400 can simultaneously drive the material beating mechanism 100 and the material turning mechanism 1000 to move in the second direction. The laser cutting mechanism 300 comprises a laser cutting structure 310 and a laser splitting structure 320, the laser cutting structure 310 is located above the second workbench 900, and the laser splitting structure 320 is located above the first workbench 200.

[0079] Specifically, the sheet can be first placed on the second workbench 900, the laser cutting structure 310 can first perform laser cutting on the sheet on the second workbench 900 to form cracks in the sheet, then the first displacement mechanism 400 can drive the sheet transfer mechanism 1000 to transfer the sheet on the second workbench 900 to the first workbench 200, such as the first jig 600 of the first workbench 200, then the first workbench 200 can drive the sheet to rotate to below the laser sheeting structure 320, the laser sheeting structure 320 performs sheeting on the sheet, thereby forming a product on the sheet, and finally, the first workbench 200 can drive the sheet to rotate to below the sheet beating mechanism 100, so that the sheet beating mechanism 100 can beat the sheet, thereby completely separating the sheet and the product.

[0080] It can be understood that, by forming cracks in the sheet through the laser cutting structure 310, and then making the sheet crack along the cracks to form a product and a waste sheet through the laser sheeting structure 320, the part with micro-connections between the product and the waste sheet can be beaten by the sheet beating mechanism 100 to separate the product and the waste sheet completely.

[0081] Referring to Figure 6 , the laser cutting device can further include a second displacement mechanism 1100, which is drivingly connected with the second workbench 900, so that the second workbench 900 can be moved to below the laser cutting structure 310 and below the sheet transfer mechanism 1000, respectively, to facilitate the sheet transfer mechanism 1000 to transfer the sheet on the second workbench 900 to the first workbench 200.

[0082] For example, the second displacement mechanism 1100 can drive the second workbench 900 to move in a third direction, so that the sheet can be moved from below the laser cutting structure 310 to below the sheet transfer mechanism 1000, wherein the third direction can be perpendicular to the first direction and the second direction, respectively.

[0083] Further, referring to Figure 7 , the laser cutting device can further include a surface turning mechanism 1200, which is drivingly connected with the first displacement mechanism 400, so that the surface turning mechanism 1200 can be moved to above the second workbench 900 to turn the sheet on the second workbench 900.

[0084] It can be understood that, in an embodiment, the cutting method of the sheet is different due to different material and processing precision requirements. For example, when one surface of the sheet is an ink surface and the other surface is a frosted surface, in order to ensure the cutting precision of the sheet, the laser cutting structure 310 can perform laser cutting on the sheet from the side of the ink surface of the sheet, and the laser sheeting structure 320 can perform sheeting on the sheet from the side of the frosted surface of the sheet, in which process, the surface turning mechanism 1200 can be used to turn the sheet on the second workbench 900.

[0085] Specifically, after the laser cutting structure 310 cuts the sheet material, the second displacement mechanism 1100 can drive the second workbench 900 to move the sheet material away from the laser cutting structure 310, the first displacement mechanism 400 can drive the turnover mechanism 1200 to move above the sheet material on the second workbench 900, and the turnover mechanism 1200 turns over the sheet material on the second workbench 900, and then the first displacement mechanism 400 can drive the material transfer mechanism 1000 to transfer the turned-over sheet material to the first workbench 200.

[0086] In an embodiment, the laser cutting device can further include a second jig 1300 and a transfer jig 1400, the second jig 1300 and the transfer jig 1400 are respectively arranged on the second workbench 900, the laser cutting structure 310 is used to cut the sheet material on the second jig 1300, and the second jig 1300 and the transfer jig 1400 can be sequentially moved below the turnover mechanism 1200 under the action of the second workbench 900.

[0087] Specifically, after the laser cutting structure 310 cuts the sheet material on the second jig 1300, the second displacement mechanism 1100 can drive the second workbench 900 to move the sheet material on the second jig 1300 to below the turnover mechanism 1200 first, so that the turnover mechanism 1200 can take the sheet material on the second jig 1300 and turn over the sheet material, then the second displacement mechanism 1100 can continue to drive the second workbench 900 to move the transfer jig 1400 below the turnover mechanism 1200, so that the turnover mechanism 1200 can place the turned-over sheet material on the transfer jig 1400, the transfer jig 1400 positions the turned-over sheet material, and then the first displacement mechanism 400 can drive the material transfer mechanism 1000 to move above the transfer jig 1400, and transfer the sheet material on the transfer jig 1400 to the first jig 600 on the first workbench 200.
