Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to a sheet metal processing machine and a fully automatic sheet metal processing device using the same. Background Technology

[0002] The existing sheet metal processing flow includes: feeding, processing, sorting, and material transportation. Processing includes laser cutting and other procedures. During the laser cutting of sheet metal, tools such as pallets are used to support the sheet metal. The pallets have many protrusions, and the sheet metal is placed on the protrusions, creating a gap between the sheet metal and the surface of the pallet. The pallet has many gaps to facilitate heat dissipation, but this makes it difficult to cut through the sheet metal. If the sheet metal is cut through directly, it may be pushed up by the protrusions, resulting in a warped shape and non-compliant sheet metal shape. Summary of the Invention

[0003] This invention provides a sheet metal processing machine and a fully automatic sheet metal processing device using the same. The sheet metal processing machine improves the way of clamping and fixing the sheet metal, eliminating the need for carrying tools such as trays, and avoiding the influence of carrying tools on the sheet metal during processing such as cutting the sheet metal, which could result in non-compliant shapes. The fully automatic sheet metal processing device uses the aforementioned sheet metal processing machine and also possesses the aforementioned technical effects of the sheet metal processing machine.

[0065] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0067] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0068] like Figures 8-14 As shown, in a first aspect, the present invention provides a sheet metal processing machine having two parallel conveyor belts 41 for conveying the sheet metal 10 during processing, so that the sheet metal 10 can reach the processing mechanism 5 of the sheet metal processing machine.

[0069] This sheet metal processing machine includes multiple gripper mechanisms 1 and multiple pad box mechanisms 2. The gripper mechanisms 1 are spaced apart on one side of each conveyor belt 41. Each gripper mechanism 1 includes a pressing drive assembly 11 and a gripper 12. The driving end of the pressing drive assembly 11 is connected to the gripper 12. The pressing drive assembly 11 can drive the gripper 12 to move along a specific path, so that the gripper 12 can perform a pressing movement, thereby pressing down the sheet metal 10 conveyed on the conveyor belt 41. The pad box mechanisms 2 are spaced apart on one side of each conveyor belt 41. At the bottom of each conveyor belt 41, each pad box mechanism 2 includes an upper drive assembly 21 and a top plate 22. The drive end of the upper drive assembly 21 is connected to the top plate 22. The upper drive assembly 21 can drive the top plate 22 to lift the conveyor belt 41 upward to maintain the shape of the conveyor belt 41 and prevent the conveyor belt 41 from sinking. In addition, the top plate 22 can cooperate with the gripper 12 to clamp the plate 10, so that the plate 10 is clamped and fixed on the conveyor belt 41 for subsequent processing of the plate 10.

[0070] This sheet metal processing machine uses a double-track conveyor belt 41 to transport the material to the processing position. The grippers 12 and the top plate 22 are used to fix the two sides of the sheet metal 10 on the conveyor belt 41 while the middle is suspended, so that the processing mechanism 5 can process the suspended part of the sheet metal 10, directly cut through the material, and let the material fall from the gap in the middle of the conveyor belt 41.

[0071] Therefore, this sheet metal processing machine improves the way the sheet metal 10 is clamped and fixed, eliminating the need for carrying tools such as trays, and avoiding the influence of carrying tools on the sheet metal 10 during processing such as cutting the sheet metal 10, which could result in non-compliant shapes.

[0072] This sheet metal processing machine includes multiple gripper mechanisms 1 and multiple pad box mechanisms 2. Multiple gripper mechanisms 1 are spaced apart on one side of each conveyor belt 41, and multiple pad box mechanisms 2 are spaced apart on the bottom of each conveyor belt 41. One gripper mechanism 1 can correspond to one pad box mechanism 2, jointly gripping one corner of the sheet metal 10. In this way, multiple gripper mechanisms 1 and multiple pad box mechanisms 2 work together to grip multiple corners of the sheet metal 10, so that the sheet metal 10 can be firmly fixed on the conveyor belt 41, ensuring the accuracy of the processing mechanism 5 in processing the sheet metal 10. For example, ensuring the accuracy of cutting the sheet metal 10 can effectively prevent the sheet metal 10 from deforming during cutting and causing non-compliant shapes. After cutting the sheet metal 10, the finished material can fall from the gap between the two conveyor belts 41 into the finished material transport vehicle 8.

[0073] When it is necessary to clamp and fix the plate 10, the clamping end of the gripper 12 needs to move close to the plate 10; when it is not necessary to clamp and fix the plate 10, the clamping end of the gripper 12 needs to move away from the plate 10. The plate 10 is conveyed on the conveyor belt 41. The gripper 12 moves on one side of the conveyor belt 41 by being driven by the downward drive assembly 11. The movement path of the gripper 12 can be horizontal, vertical, or inclined at a certain angle to the horizontal plane. Alternatively, the movement path of the gripper 12 can be rotational. For example, the downward drive assembly 11 can drive the gripper 12 to rotate in the up and down direction. When it is necessary to clamp and fix the plate 10, the downward drive assembly 11 drives the gripper 12 to rotate downward so that the clamping end of the gripper 12 can abut against the upper surface of the plate 10. When it is not necessary to clamp and fix the plate 10, the downward drive assembly 11 can drive the gripper 12 to rotate upward so that the clamping end of the gripper 12 is above the conveyor belt 41.

[0074] The movement mode of the gripper 12 is set to rotate or translate in the up and down direction, so that the gripper 12 can work well with the pad box mechanism 2 to achieve a stable gripping of the plate 10. The gripper 12 abuts against the upper surface of the plate 10 from top to bottom, and the top plate 22 of the pad box mechanism 2 abuts against the bottom of the conveyor belt 41 from bottom to top to support the lower surface of the plate 10. In this way, the plate 10 is less likely to shift position when it is processed.

[0075] In addition, setting the movement mode of the gripper 12 to rotate or translate in the vertical direction can effectively reduce the space required by the gripper 12 in the horizontal direction when it moves, which makes it easier for personnel to move around the conveyor belt 41 and perform some necessary operations.

[0076] The downward pressure drive assembly 11 includes a downward pressure support 111 and a downward pressure drive 112. The downward pressure support 111 is disposed on one side of the conveyor belt 41. Specifically, the conveyor belt 41 is disposed on the conveyor support 42 via the roller shaft 43. The downward pressure support 111 is fixed on the conveyor support 42. The downward pressure drive 112 is disposed on the downward pressure support 111. The gripper 12 has a downward pressure part 13 and a transmission part 14. The transmission part 14 is rotatably disposed on the downward pressure support 111 and is connected to the drive end of the downward pressure drive 112. The downward pressure drive 112 can drive the transmission part 14 of the gripper 12 to rotate, so that the downward pressure part 13 of the gripper 12 can rotate downward and press down on the plate 10, or, so that the downward pressure part 13 of the gripper 12 can rotate upward and move away from the plate 10.

[0077] Relying on the torque provided by the downward drive 112, the lower side of the head end and the middle of the downward pressing part 13 of the gripper 12 can abut against the upper surface of the plate 10. Furthermore, the downward pressing part 13 of the gripper 12 can deform when it contacts the upper surface of the plate 10, especially the head end and the middle of the downward pressing part 13. Thus, the head end and the middle of the downward pressing part 13 can adapt to plates 10 of different thicknesses and provide sufficient downward pressure to the plate 10 so that the plate 10 can be stably clamped on the conveyor belt 41.

[0078] Specifically, the pressing part 13 of the gripper 12 can be made of a material with a certain strength but capable of deformation after contacting the plate 10, including but not limited to polyurethane (PU), fluororubber (FKM) and ionomer metal composite (IMPC). These materials have excellent mechanical properties, such as high wear resistance, high mechanical strength (tensile strength, tear strength, high load-bearing capacity) and excellent resilience, which enable them to withstand the impact caused by the deformation of the steel plate when fixing the cutting steel plate. They also have outstanding high temperature resistance and a certain resistance to the high temperature brought about by laser cutting. Furthermore, they have electrical insulation and shock absorption properties, and are highly resistant to situations where the steel plate becomes electrified or other unexpected situations occur.

[0079] When the gripper 12 is designed to move in a vertical direction to cooperate with the pad box mechanism 2 to clamp the plate 10, the gripper 12 can be made of metal material in addition to the above-mentioned materials.

[0080] When it is necessary to clamp and fix the plate 10, the downward drive 112 drives the transmission part 14 of the gripper 12 to rotate relative to the downward support 111, so that the head end and the lower side of the middle part of the downward pressing part 13 can abut against the upper surface of the plate 10, and the head end, middle part and tail end of the downward pressing part 13 will all undergo different degrees of deformation.

[0081] However, since the torque provided by the downward drive 112 to the transmission part 14 of the gripper 12 is easily concentrated at a certain position on the head end or lower middle side of the downward drive 13 due to the downward drive 112 providing torque to the gripper 12.

[0082] In this situation, the stress is too concentrated on the pressing part 13 of the gripper 12, causing excessive deformation of the pressing part 13. This can easily lead to excessive fatigue of the pressing part 13 of the gripper 12, making it unable to provide stable and sufficient downward pressure. Consequently, the effect of clamping and fixing the plate 10 is affected, ultimately affecting the processing accuracy of the plate 10.

[0083] Furthermore, under such circumstances, the service life of the gripper 12 is greatly reduced, which will increase material waste and unnecessary cost expenditures.

[0084] Therefore, when the pressing part 13 of the gripper 12 is driven to press down on the plate 10, the head end and the middle part of the pressing part 13 should be deformed to a similar degree so that the stress on the pressing part 13 is distributed at its head end and the middle part.

[0085] Specifically, the pressing part 13 includes a pressing frame 131 and a plurality of first buffer rods 132. The pressing frame 131 is shaped with a small head and a large tail. The tail end of the pressing frame 131 is connected to the transmission part 14. The plurality of first buffer rods 132 are disposed inside the pressing frame 131, and the two ends of the first buffer rods 132 are respectively connected to the frame edge of the pressing frame 131. The plurality of first buffer rods 132 allow the pressing frame 131 to deform when pressing the plate 10, so that the head end and the lower side of the middle part of the pressing frame 131 can form surface contact with the plate 10.

[0086] Because the pressure frame 131 is shaped with a small head and a large tail, it is driven to rotate. When it comes into contact with the plate 10, the head and lower side of the middle of the pressure frame 131 have a sufficiently large area to contact the upper surface of the plate 10, which helps to disperse stress.

[0087] The torque generated by the driving end of the downward drive 112 on the gripper 12 is transmitted to the downward frame 131 via the transmission part 14 of the gripper 12. The lower side of the head end and middle part of the downward frame 131 abuts against the upper surface of the plate 10. At the same time, the downward frame 131 is subjected to the reaction force of the plate 10. Thus, under the drive of the torque of the downward drive 112 and the reaction force of the plate 10, the head end and middle part of the downward frame 131 will deform. The first buffer rod 132 allows the downward frame 131 to undergo adaptive deformation so that the stress is transmitted to the first buffer rod 132. At this time, the stress is distributed on the first buffer rod 132 and the head end and middle part of the downward frame 131. This arrangement can effectively prevent the downward part 13 from deforming excessively and ensure its downward pressing action on the plate 10, so as to cooperate with the pad box mechanism 2 to achieve stable clamping of the plate 10.

[0088] More specifically, both ends of the first buffer rod 132 have cross-sections 132a. The pressing frame 131 has an upper frame edge 131a and a lower frame edge 131b. The two ends of the first buffer rod 132 are connected to the upper frame edge 131a and the lower frame edge 131b, respectively. When the pressing frame 131 presses down on the plate 10, the first buffer rod 132 can deform accordingly so that the cross-section 132a abuts against the upper frame edge 131a or the lower frame edge 131b and is in contact with the upper frame edge 131a or the lower frame edge 131b. Thus, the first buffer rod 132 can stand between the upper frame edge 131a and the lower frame edge 131b to provide support for the upper frame edge 131a and the lower frame edge 131b. After deformation, the entire pressing part 13 forms a support structure with a certain strength to generate a sufficiently large downward pressure on the plate 10.

[0089] It should be noted that the formation of the cross-section 132a can be understood as dividing each end of the first buffer rod 132 into two parts. One part is connected to the upper frame edge 131a or the lower frame edge 131b, and the other part has a flat cut surface. When making the gripper 12, the two ends of the first buffer rod 132 can be connected to the upper frame edge 131a and the lower frame edge 131b respectively, and a small piece can be cut off from both ends of the first buffer rod 132 using a tool. The cut will serve as the cross-section 132a. Alternatively, the gripper 12 can be manufactured using 3D printing technology, and the cross-section 132a will be made directly when making the first buffer rod 132. When the first buffer rod 132 deforms, it will bend, and the upper frame edge 131a and the lower frame edge 131b will move closer to each other. Thus, the cross-section 132a on the end of the first buffer rod 132 will abut against the inner side of the upper frame edge 131a or the lower frame edge 131b.

[0090] When the gripper 12 is in its natural state, that is, when the gripper 12 is not driven to abut against the plate 10, the first buffer rod 132 is in an extended state. At this time, the surface extension direction of the cross section 132a forms a certain angle with the axial direction of the first buffer rod 132. This angle can be 120° to 150°.

[0091] The pressure frame 131 has a shape that is small at the head and large at the tail. In order to adapt to the shape of the pressure frame 131 and ensure that the stress on each first buffer rod 132 is similar when the pressure plate 10 is pressed down, the first buffer rods 132 can be arranged side by side inside the pressure frame 131, and the length of the first buffer rods 132 gradually increases from the head end to the tail end of the pressure frame 131.

[0092] By placing the first buffer rods 132 side by side inside the pressure frame 131, the material used to manufacture the gripper 12 can be effectively reduced, unnecessary costs can be reduced, and mass production of the gripper 12 can be achieved.

[0093] Meanwhile, it is ensured that when the pressing frame 131 is driven to just contact the upper surface of the plate 10, the first buffer bars 132 are almost perpendicular to the upper surface of the plate 10. As the pressing drive 112 continues to drive, the first buffer bars 132 all deform in the same direction (towards the tail end of the pressing frame 131). Thus, the first buffer bars 132 can provide stable support for the upper frame edge 131a and the lower frame edge 131b, so that the entire pressing part 13 forms a support structure with a certain strength after deformation.

[0094] Preferably, to further reduce material consumption while ensuring that the pressing part 13 of the gripper 12 has the above-mentioned functions and effects, the pressing frame 131 can be designed as a shape symmetrical along its central axis. The extension direction of the central axis of the pressing frame 131 is from the head end to the tail end of the pressing frame 131. At this time, the pressing frame 131 mainly includes three frame sides, namely the upper frame side 131a, the lower frame side 131b and the bottom frame side. The three frame sides are connected end to end in sequence, and rounded corners are provided at the connection points. From the head end to the tail end of the pressing frame 131, the length of the first buffer rod 132 increases in a stepped manner, and the distance between two adjacent first buffer rods 132 is several times the thickness of the first buffer rod 132.

[0095] When the lower side of the head end and middle of the pressing frame 131 abuts against the upper surface of the plate 10, the first buffer rod 132 can deform to allow the pressing frame 131 to deform. Furthermore, the first buffer rod 132 undergoes adaptive deformation according to the different thicknesses of the plate 10, and the pressing frame 131 also undergoes adaptive deformation to provide good pressing action on plates 10 of different thicknesses.

[0096] Therefore, the first buffer rod 132 is required to be easily deformable.

[0097] Meanwhile, the first buffer rod 132 can provide stable support for the upper frame edge 131a and the lower frame edge 131b of the pressing frame 131, so that the entire pressing part 13 forms a support structure with a certain strength.

[0098] Therefore, the first buffer rod 132 is required to have a certain strength.

[0099] In this regard, this application defines the shape of the first buffer rod 132 as follows:

[0100] The cross-sectional shape of the first buffer rod 132 includes a circle, an ellipse, a rectangle and its approximations, and a triangle and its approximations. The approximation of a rectangle is a closed figure formed by alternating straight line segments and curved line segments. The approximation of a triangle is a closed figure formed by connecting straight line segments and / or curved line segments, and rounded corners are provided at the connection points of the line segments.

[0101] When the cross-sectional shape of the first buffer rod 132 is elliptical or rectangular or its approximate shape, the major axis of the ellipse is parallel to the thickness direction of the pressure frame 131, and the length direction of the rectangle or its approximate shape is parallel to the thickness direction of the pressure frame 131.

[0102] When the cross-sectional shape of the first buffer rod 132 is a triangle or its approximate shape, one of the vertices of the triangle or its approximate shape is opposite to the tail end of the pressure frame 131, and the extension direction of the side corresponding to this vertex is parallel to the thickness direction of the pressure frame 131.

[0103] Furthermore, whether it is a rectangular approximation or a triangle and its approximation, they are all axially symmetric figures, and the axis of symmetry of the figure is perpendicular to the straight line containing the thickness direction of the pressing frame 131.

[0104] The shape of the first buffer rod 132 is designed in this way to ensure that it can deform under the pressure of the downward drive 112 and the plate 10, and to give the first buffer rod 132 a certain strength so that it can abut against the upper frame edge 131a and the lower frame edge 131b of the downward frame 131, so that the entire downward part 13 forms a support structure with a certain strength.

[0105] In some embodiments, inside the pressure frame 131, a first buffer rod 132 is provided side by side from its head end to its tail end.

[0106] In other embodiments, other buffer rods may be provided inside the pressure frame 131, in conjunction with the first buffer rod 132, to support the upper frame edge 131a and the lower frame edge 131b of the pressure frame 131, thereby enabling the entire pressure part 13 to exert a good pressure effect on the plate 10, while realizing stress dispersion of the entire pressure part 13 and avoiding excessive deformation.

[0107] The pressing part 13 also includes a plurality of second buffer rods 133 disposed inside the pressing frame 131. The two ends of the plurality of second buffer rods 133 are respectively connected to the side of the corresponding position inside the pressing frame 131, and the plurality of second buffer rods 133 are connected in sequence from the head end to the tail end of the pressing frame 131, so that the second buffer rods 133 are inclined relative to the first buffer rod 132.

[0108] When the gripper 12 is in its natural state, that is, when the gripper 12 is not driven to abut against the plate 10, the second buffer rod 133, together with the first buffer rod 132 nearby and the upper frame edge 131a or the lower frame edge 131b, forms a triangular structure. This triangular structure has good stability, which allows it to effectively exert sufficient downward pressure on the plate 10 when pressing it down, so as to cooperate with the pad box mechanism 2 to firmly clamp the plate 10 for processing. At the same time, this triangular structure will not produce excessive deformation, so that the entire gripper 12 can be reused.

[0109] Preferably, the second buffer rod 133 is located near the head end of the pressing frame 131, or the second buffer rod 133 is located in the middle of the pressing frame 131 and is surrounded by the first buffer rod 132.

[0110] The position of the second buffer rod 133 inside the pressure frame 131 will result in different structural strength and deformation capacity of the entire pressure part 13, so as to adapt to the plate 10 of different thicknesses.

[0111] When pressing down on some relatively thin plates 10, the second buffer rod 133 can be set as a gripper 12 near the head end. The gripper 12 is driven to rotate, so that the head end of the gripper 12 contacts the plate 10 before the middle part. At this time, the deformation capability of the head end of the pressing part 13 of the gripper 12 is stronger than that of the middle part. The head end of the pressing part 13 will deform first, so that the middle part can also make good contact with the plate 10. As the pressing drive 112 continues to drive, both the head end and the middle part of the pressing part 13 can deform, thereby achieving pressing down and fixing the plate 10.

[0112] When pressing down on some relatively thick plates 10, the second buffer rod 133 can be set as a gripper 12 near the middle position. The gripper 12 is driven to rotate, so that the middle position of the gripper 12 contacts the plate 10 before its head position. At this time, the deformation capacity of the middle position of the pressing part 13 of the gripper 12 is stronger than that of its head position. The middle position will deform first, so that its head position can also make good contact with the plate 10. As the pressing drive 112 continues to drive, both the head position and the middle position of the pressing part 13 can deform, thereby achieving pressing down and fixing the plate 10.

[0113] In some other embodiments, the pressing part 13 further includes a plurality of third buffer rods 134 disposed inside the pressing frame 131. Some of the third buffer rods 134 are parallel to the upper frame edge 131a of the pressing frame 131, and some of the third buffer rods 134 are parallel to the lower frame edge 131b of the pressing frame 131. The third buffer rods 134 intersect with the first buffer rods 132 one-to-one, or the third buffer rods 134 intersect with the first buffer rods 132 one-to-many.

[0114] This configuration creates a stable mesh support structure between the third buffer rod 134 and the first buffer rod 132, which can be adapted to various thicknesses of the plate 10 and can exert a good downward pressure effect on plates 10 of different thicknesses.

[0115] A gripper mechanism 1 and its corresponding pad box mechanism 2 can clamp one corner of the plate 10. In this way, multiple gripper mechanisms 1 and multiple pad box mechanisms 2 work together to clamp multiple corners around the plate 10.

[0116] For each gripper mechanism 1 and its corresponding pad mechanism 2, the size of the contact area between them and the plate 10 directly affects the clamping and fixing effect of the two on the plate 10. The larger the contact area, the better the clamping and fixing effect on the plate 10.

[0117] Each gripper mechanism 1 includes multiple grippers 12, which are spaced apart. The transmission part 14 of each gripper 12 is rotatably mounted on the pressing support 111 and is simultaneously connected to the driving end of the pressing drive 112. The pressing drive 112 can simultaneously drive the transmission part 14 of each gripper 12 to rotate, so that the pressing part 13 of each gripper 12 can simultaneously press down on the plate 10.

[0118] The downward drive 112 is a motor. Multiple gears are sleeved on the outer periphery of the output shaft of the motor. Each gear meshes with the transmission part 14 of each gripper 12. Thus, the motor can simultaneously drive the transmission part 14 of each gripper 12 to rotate, so that the downward pressing part 13 of each gripper 12 can simultaneously press down on the plate 10.

[0119] Although the contact area between these grippers 12 and the plate 10 is relatively small, since these grippers 12 are spaced apart, when these grippers 12 press down on the plate 10 together, the area formed by connecting the pressing positions is relatively large. Therefore, these grippers 12, in coordination with a pad box mechanism 2, can also form a good clamping and fixing effect on the plate 10.

[0120] It should be noted that the transmission part 14 of the gripper 12 has meshing teeth to mesh with the gear on the motor output shaft. When manufacturing the gripper 12, the material of its transmission part 14 can be metal or high-strength plastic. Therefore, the transmission part 14 and the pressing part 13 can be manufactured separately and connected and fixed by welding. Alternatively, the transmission part 14 and the pressing part 13 can be directly manufactured into an integral structure by using 3D printing technology, injection molding process, etc.

[0121] The conveyor belt 41 is mounted on the conveyor support 42 via the roller shaft 43. The conveyor belt 41 and the plate 10 are in flexible contact. During the conveying process of the plate 10, the conveyor belt 41 will sink to a certain extent under the action of the weight of the plate 10. Furthermore, when the gripper mechanism 1 is driven to move and the gripper 12 presses down on the plate 10, the sinking of the conveyor belt 41 will be aggravated. In this case, if the pad box mechanism 2 is set off from the gripper mechanism 1, the pad box mechanism 2 and the gripper mechanism 1 cannot form a good clamping and fixing effect on the plate 10. When processing the plate 10, it is easy to cause the position of the plate 10 to shift, affecting the processing accuracy of the plate 10.

[0122] To avoid this situation, a pad box mechanism 2 needs to be positioned below a gripper mechanism 1. The gripper 12 abuts against the upper surface of the plate 10 from top to bottom, and the top plate 22 of the pad box mechanism 2 abuts against the bottom of the conveyor belt 41 from bottom to top to support the lower surface of the plate 10. This can effectively clamp and fix the plate 10.

[0123] When the conveyor belt 41 is conveying the plate 10, the upper drive assembly 21 will first cause the top plate 22 to descend, so that the upper surface of the top plate 22 will not contact the bottom of the conveyor belt 41. In this way, the conveyor belt 41 will not rub against the upper surface of the top plate 22 during movement, thus preventing wear on the conveyor belt 41.

[0124] When the conveyor belt 41 is conveying the plate 10, the movement of the conveyor belt 41 will cause shaking. This is due to the assembly error of the conveyor belt 41 during assembly, as well as the processing error of the power equipment that drives the conveyor belt 41. The shaking of the conveyor belt 41 will easily cause the plate 10 to shake, making the position of the plate 10 inaccurate, which will affect the processing accuracy of the plate 10 by the subsequent processing mechanism 5.

[0125] Generally, multiple rollers can be spaced out on the conveyor support 42. The conveyor belt 41 is wrapped around the outer circumference of the roller shaft 43 and the rollers. The roller shaft 43 and the rollers can support the conveyor belt 41 to prevent the conveyor belt 41 from sinking too much. This can effectively reduce the amplitude of the swaying when the conveyor belt 41 moves, so that the plate 10 will not sway significantly when it is conveyed on the conveyor belt 41. Therefore, the plate 10 will not shift its position relative to the conveyor belt 41, thereby ensuring the processing accuracy of the plate 10 by the subsequent processing mechanism 5.

[0126] And / or, each pad box mechanism 2 also includes a guide rod 24, the top of which is provided with a rolling component 25. When the conveyor belt 41 is moving, the guide rod 24 can be driven to move upward so that the rolling component 25 at its top presses against the bottom of the conveyor belt 41. This can also effectively reduce the amplitude of the swaying of the conveyor belt 41 when it is moving. At the same time, the friction between the conveyor belt 41 and the rolling component 25 when it is moving will force the rolling component 25 to rotate, which can effectively reduce the wear of the conveyor belt 41.

[0127] In some embodiments, the bottom of the top plate 22 is connected to an upper push rod 23, and the upper push rod 23 is provided with a first engagement part.

[0128] A second engagement part is provided on the guide rod 24.

[0129] The upper drive assembly 21 includes an upper drive 211 and an upper drive gear 212.

[0130] The drive shaft of the upper drive 211 is connected to the middle of the upper drive gear 212. The guide rod 24 and the upper push rod 23 are spaced apart. The upper drive gear 212 simultaneously meshes with the first meshing part and the second meshing part.

[0131] The upper drive 211 can drive the upper rod 23 to rise while simultaneously lowering the guide rod 24, or the upper drive 211 can drive the guide rod 24 to rise while simultaneously lowering the upper rod 23. When the guide rod 24 rises, the rolling component 25 can receive the conveyor belt 41 and roll under the force of the conveyor belt 41.

[0132] When the plate 10 is placed on the conveyor belt 41 for conveying, the upper drive 211 will drive the guide rod 24 to rise and the upper rod 23 to fall, so that the rolling part 25 supports the bottom of the conveyor belt 41 to reduce the sway of the conveyor belt 41. In addition, the top plate 22 on the upper rod 23 does not contact the bottom of the conveyor belt 41, and there is no friction between it and the bottom of the conveyor belt 41. The friction between the rolling part 25 and the bottom of the conveyor belt 41 is rolling friction. The rolling friction will not cause excessive wear on the bottom of the conveyor belt 41. In this way, the conveyor belt 41 can be put into long-term use.

[0133] Once the plate 10 is in place, the upper drive 211 will drive the guide rod 24 to descend, while the upper push rod 23 will rise, so that the top plate 22 at the top of the upper push rod 23 can support the bottom of the conveyor belt 41. Compared with the rolling component 25, the upper surface of the top plate 22 has a larger contact area with the bottom of the conveyor belt 41, so that the top plate 22 can cooperate well with the gripper 12 of the gripper mechanism 1 to clamp and fix the plate 10.

[0134] Preferably, the rolling component 25 can be a common component such as a roller or a ball bearing.

[0135] Preferably, the downward drive 112 and the upward drive 211 can be selected from common motor devices in the prior art that can be controlled and realize the above actions. The way the downward drive 112 and the upward drive 211 are controlled can refer to the way existing motor devices are controlled and generate actions. Here, this application will not describe in detail the circuit connection method and control logic of the downward drive 112 and the upward drive 211.

[0136] As mentioned above, the larger the contact area between the gripper 12 of the gripper mechanism 1 and the plate 10, the better the downward pressure effect of the gripper 12 on the plate 10. Similarly, the larger the contact area between the top plate 22 of the pad box mechanism 2 and the conveyor belt 41, the better the upward pressure effect of the top plate 22 on the conveyor belt 41. Thus, the gripper 12 and the top plate 22 work together to clamp and fix the plate 10 better.

[0137] In the case that each gripper mechanism 1 includes multiple grippers 12, each pad box mechanism 2 also includes multiple top plates 22, and each pad box mechanism 2 also includes multiple guide rods 24, each guide rod 24 being provided with a rolling component 25.

[0138] Specifically, the upper drive assembly 21 also includes two transmission gears 213, which are respectively disposed on opposite sides of the upper drive gear 212 and mesh with the upper drive gear 212. Each transmission gear 213 is provided with a guide rod 24 and an upper push rod 23 on opposite sides. The transmission gear 213 meshes with the first meshing part and the second meshing part respectively.

[0139] The upper drive 211 applies torque to the upper drive gear 212, causing the upper drive gear 212 to drive the two transmission gears 213 to rotate, thereby driving the two guide rods 24 to rise and simultaneously causing the two upper push rods 23 to fall, or driving the two guide rods 24 to fall and simultaneously causing the two upper push rods 23 to rise.

[0140] This ensures that when the conveyor belt 41 moves, multiple rolling parts 25 on each pad box mechanism 2 are supported on the bottom of the conveyor belt 41, and multiple pad box mechanisms 2 are spaced apart on the bottom of each conveyor belt 41. This makes the movement of the conveyor belt 41 more stable and greatly reduces the swaying of the conveyor belt 41.

[0141] This also ensures that after the plate 10 is in place, the multiple top plates 22 on each pad box mechanism 2 abut against the bottom of the conveyor belt 41. Multiple pad box mechanisms 2 are spaced apart at the bottom of each conveyor belt 41, and each pad box mechanism 2 cooperates with a gripper mechanism 1. This allows for the stable clamping of the plate 10, preventing it from shifting position during subsequent processing, thus ensuring the accurate positioning of the plate 10 and guaranteeing the processing precision of the plate 10.

[0142] like Figures 1-8 As shown, this sheet metal processing machine also includes a picking mechanism 3, a conveying mechanism 4, and a processing mechanism 5.

[0143] The picking mechanism 3 is located above or to one side of the conveying mechanism 4. When feeding the board 10, the picking mechanism 3 can pick up the board 10 transported by external equipment and move the board 10 onto the conveying mechanism 4 so that the board 10 can be conveyed on the conveying mechanism 4.

[0144] The conveying mechanism 4 has two parallel conveyor belts 41. The two conveyor belts 41 can receive the plates 10 transported by the picking mechanism 3 and transport the plates 10 to the location of the processing mechanism 5. The plates 10 can be located below the processing mechanism 5 or on one side of the processing mechanism 5.

[0145] The gripper mechanism 1 is spaced apart on one side of each conveyor belt 41, and the pad box mechanism 2 is spaced apart at the bottom of each conveyor belt 41. After the conveying mechanism 4 conveys the plate 10 to the position, the gripper mechanism 1 and the pad box mechanism 2 act simultaneously to fix the plate 10 at the processing mechanism 5 so that the processing mechanism 5 can process the plate 10.

[0146] The processing mechanism 5 includes a processing module 51, which is movably disposed above the conveyor belt 41 and is used to process the sheet material 10.

[0147] The external equipment can be a loading and transport vehicle. On-site personnel can remotely control the loading and transport vehicle to drive under the picking mechanism 3. Alternatively, the driving path of the loading and transport vehicle can be planned in advance. After the loading and transport vehicle carries the board 10, it can drive under the picking mechanism 3 on its own so that the picking mechanism 3 can pick up the board 10 and place the board 10 on the conveying mechanism 4.

[0148] The processing module 51 includes a laser cutting module. After being powered on, the laser cutting module can perform laser cutting on the sheet 10. During processing, the laser cutting module will run according to the planned route and will directly cut through the sheet 10. According to the planned route, if the material cut through is good material, the good material will fall from between the two conveyor belts 41 into the good material box 81 below. If the material cut through is waste or scrap, the waste or scrap will fall from between the two conveyor belts 41 into the waste box 91 below.

[0149] Because laser cutting is a sequential process according to program requirements, it is known whether the material falling next will be good material or waste material before the material is cut through. If it is good material, the good material box 81 will be switched to the receiving position in advance. At this time, the waste material box 91 is located at the bottom of the good material box 81, and both are located below the conveyor belt 41. If it is waste material, the good material box 81 will be cut out below the conveyor belt 41, leaving only the waste material box 91 in the receiving position. The waste material will fall directly into the waste material box 91 due to gravity.

[0150] This sheet metal processing machine also includes a protective cover 6, which is installed around the laser cutting module and the gripper mechanism 1. The protective cover 6 is used to absorb part of the laser energy and prevent the sheet metal 10 from flying debris when laser cutting the sheet metal 10, so as to protect the personnel on site from injury.

[0151] The picking mechanism 3 includes a picking drive assembly 31 and an adsorption assembly 32. The driving end of the picking drive assembly 31 is connected to the adsorption assembly 32. A negative pressure adsorption can be formed between the adsorption assembly 32 and the plate 10. The picking drive assembly 31 can drive the adsorption assembly 32 to move in the first direction L1, the second direction L2 and the third direction L3 respectively, so that the adsorption assembly 32 can contact the plate 10 on external equipment such as a loading and transport vehicle and pick up the plate 10. The first direction L1, the second direction L2 and the third direction L3 are perpendicular to each other.

[0152] The pickup drive assembly 31 includes a first slide rail 312, a first slide block 313, a second slide rail 314, a second slide block 315, and a pickup bracket 316.

[0153] Two first slide rails 312 are formed on the mounting bracket 311, which stands above the conveying bracket 42. Both first slide rails 312 extend along the first direction L1.

[0154] The two ends of the first slide block 313 are connected to the two first slide rails 312 respectively. A first drive 317 is provided on the first slide block 313. Both first slide rails 312 are provided with meshing tooth structures. A first gear is provided on the outer periphery of the output shaft of the first drive 317. The first gear can mesh with the meshing tooth structure on the first slide rail 312. The first drive 317 can drive the first gear to have a tendency to move relative to the meshing tooth structure on the first slide rail 312. However, since the mounting bracket 311 is connected to the ground, the first slide rail 312 is fixed on the mounting bracket 311 and does not move. Therefore, the meshing tooth structure on the first slide rail 312 reacts to the first gear, causing the first gear to move along the first slide rail 312. This causes the first drive 317 and the first slide block 313 to slide along the first slide rail 312 in the first direction L1.

[0155] The second slide rail 314 is formed on the first slide block 313. The second slide rail 314 extends along the second direction L2. The second slide block 315 is slidably disposed on the second slide rail 314. A second drive 318 is also disposed on the first slide block 313. The drive end of the second drive 318 is connected to the second slide block 315. The second drive 318 can drive the second slide block 315 to slide along the second slide rail 314 and in the second direction L2.

[0156] A pickup bracket 316 is provided on the second slide 315, and a third drive 319 is provided on the second slide 315. The drive end of the third drive 319 is connected to the pickup bracket 316, and the third drive 319 can drive the pickup bracket 316 to slide on the third direction L3.

[0157] The adsorption component 32 is mounted on the pickup bracket 316. When the first drive 317 is activated, the adsorption component 32 can slide along the first slide block 313 in the first direction L1. When the second drive 318 is activated, the adsorption component 32 can slide along the second slide block 315 in the second direction L2. When the third drive 319 is activated, the adsorption component 32 can slide along the pickup bracket 316 in the third direction L3. Because the first direction L1, the second direction L2, and the third direction L3 are perpendicular to each other, the adsorption component 32 can move in three-dimensional space, approach the plate 10, and form a negative pressure adsorption with the plate 10 to pick up the plate 10 and place the plate 10 on the conveyor belt 41 so that the plate 10 is conveyed on the conveyor belt 41.

[0158] Specifically, the first drive 317 is located in the middle of the first slide block 313, and the first gear on the output shaft of the first drive 317 engages with the meshing gear structure on the first slide rail 312 via a synchronous belt, a gear and a synchronous shaft to achieve meshing transmission.

[0159] In other embodiments, the first drive 317 can be mounted on the mounting bracket 311 and can be connected to the first slide 313 via a synchronous belt structure, a lead screw and nut transmission structure, etc. The first drive 317 is stationary and will drive the first slide 313 to slide.

[0160] Alternatively, a power device such as a cylinder or linear motor can be used to drive the first slide block 313 to slide. The connection method between the power device such as the cylinder or linear motor and the first slide block 313 can refer to the common settings in the prior art.

[0161] Similarly, the power connection between the second drive 318 and the second slide 315, and the power connection between the third drive 319 and the pickup bracket 316, can refer to the power connection between the first drive 317 and the first slide 313 described above.

[0162] In addition, the pickup drive component 31 can also be a multi-axis robot, such as a four-axis robot or a six-axis robot.

[0163] Optionally, the adsorption component 32 can be a suction cup, a vacuum suction cup, or a magnetic structure, etc. The suction cup, vacuum suction cup, and magnetic structure can be selected from relevant structures in the prior art. Here, this application will not describe the detailed structure of the adsorption component 32.

[0164] After the picking mechanism 3 picks up the board 10, it aligns it with a sensor such as an infrared sensor or a vision camera, and then places the board 10 on the double-track conveyor belt 41.

[0165] The processing mechanism 5 also includes a processing drive component 52. The drive end of the processing drive component 52 is connected to the processing module 51. The processing drive component 52 can drive the processing module 51 to move in the first direction L1, the second direction L2 and the third direction L3 respectively. The first direction L1, the second direction L2 and the third direction L3 are perpendicular to each other.

[0166] Similarly, the processing drive component 52 can refer to the above-described method of driving the adsorption component 32 with the pickup drive component 31 to drive the processing module 51 to move in the first direction L1, the second direction L2, and the third direction L3 respectively. For example, by setting a first lead screw and nut drive structure, the processing module 51 can be driven to move in the first direction L1; by setting a second lead screw and nut drive structure, the processing module 51 can be driven to move in the second direction L2; and by setting a third lead screw and nut drive structure, the processing module 51 can be driven to move in the third direction L3. Alternatively, by setting a cylinder, linear motor, or other power equipment, the processing module 51 can be directly driven to move in the third direction L3. The positional relationship and transmission method of the first lead screw and nut drive structure, the second lead screw and nut drive structure, and the third lead screw and nut drive structure or the cylinder, linear motor, etc., can refer to the relevant arrangement and positional relationship of these structures in the prior art.

[0167] The present invention provides a fully automatic board processing device in a second aspect, including a board processing machine and a transport device as described in the first aspect.

[0168] The sheet metal processing machine includes a picking mechanism 3, a conveying mechanism 4, a processing mechanism 5, multiple gripper mechanisms 1, and multiple pad box mechanisms 2.

[0169] The picking mechanism 3 is used to pick up the plate 10 and transport the plate 10 to the conveying mechanism 4. The conveying mechanism 4 can receive the plate 10 transported by the picking mechanism 3 and transport the plate 10 to the processing mechanism 5, so that the gripper mechanism 1 and the pad mechanism 2 can clamp the plate 10 together to facilitate the processing of the plate 10, such as laser cutting the plate 10.

[0170] The transport device has a good material box 81 for receiving good materials and a waste material box 91 for receiving waste materials. The good material box 81 or the waste material box 91 can be driven to switch to the bottom of the conveyor belt 41. When the sheet 10 is processed, good materials and waste materials will fall from between the two conveyor belts 41. The good materials will fall into the good material box 81 and the waste materials will fall into the waste material box 91.

[0171] Specifically, the transport device includes a route frame 7, a good material transport vehicle 8, and a waste material transport vehicle 9. The route frame 7 is located below the two conveyor belts 41. The good material transport vehicle 8 has a good material box 81 and is configured to travel on the route frame 7 such that the good material box 81 is located below or not below the conveyor belts 41. The waste material transport vehicle 9 has a waste material box 91 and is configured to travel below the route frame 7 such that the waste material box 91 is located below or not below the conveyor belts 41.

[0172] When processing the sheet 10, such as when laser cutting the sheet 10, the cutting is carried out in sequence according to the program requirements. Before the material is cut through, it is known whether the next material to fall will be good material or waste material. If it is good material, the good material transport vehicle 8 enters from the route frame 7 and enters below the two conveyor belts 41, so that the good material falls into the good material box 81 of the good material transport vehicle 8. If it is waste material, before the waste material is cut through and falls, the on-site personnel can control the good material transport vehicle 8 to drive away from the conveyor belt 41, so that the waste material falls into the waste material transport vehicle 9 at the bottom.

[0173] The fully automatic sheet metal processing equipment of this application can realize the full automation of feeding, processing, sorting of good and bad materials and material transportation. It adopts the suction gripping method for feeding. After feeding, the material is transported to the processing machine tool by the double track conveyor belt 41. The sheet metal 10 is then clamped by the specially designed flexible gripper 12 for processing. During processing, the laser cutting module will run according to the planned route to cut through the sheet metal 10. According to the planned route design, if the cut material is good material, the good material transport vehicle 8 will enter through the side route frame 7, move to the bottom of the conveyor belt 41 and pick up the good material. If the cut material is waste or scrap, it will fall directly through the middle gap of the conveyor belt 41 to the bottom waste material transport vehicle 9. After processing, the remaining waste sheet metal frame will continue to move backward by the conveyor belt 41 and finally fall to the waste material transport vehicle 9 after being blocked by the iron plate.

[0174] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
