Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to an automatic material separation device. Background Art

[0002] Existing equipment uses vacuum suction cups to grasp and separate materials. Specifically, the materials are uniformly placed on the material table. When the suction cup moves to the top of the material table, the suction cup slowly moves downward, and the vacuum generator works at the same time. When the suction cup contacts the material to be separated, the suction cup is vacuumed, the material is sucked, and the suction cup moves up a little, carrying the material. At this time, the double material sensor detects whether the material being grasped is a single material or multiple materials. After repeated grasping to confirm that it is a single material, the suction cup moves the material to the workbench, completing the grasping process, thereby realizing the separation function of the material.

[0003] However, when the suction cup absorbs multiple materials, the suction cup cannot absorb the materials that are not in direct contact with the suction cup, and the materials may fall off during the movement of the suction cup, which may easily cause safety accidents. At the same time, this type of suction cup can only separate large flat materials, but not special-shaped materials, and has low versatility. In addition, when the materials are tightly fitted, the materials are adsorbed on each other, and the separation is often not completed by relying solely on the gravity of the lower layer of materials.

[0004] In view of this, it is necessary to provide an improved automatic material separation device to solve the above problems. Summary of the invention

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of the present invention, it is necessary to understand that when the automatic material separation device is in normal use, the material thickness direction is the up-down direction, and the direction in which the automatic material separation device drives the material to be separated to move is the up direction. It can be understood that the orientation or position relationship defined in the present invention is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. The terms "first", "second", etc. are used only 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 as "first" and "second" may explicitly or implicitly include one or more of the features.

[0032] like Figures 1 to 5 As shown, the present invention provides an automatic material separation device 100, comprising a machine base 1, at least two material separation mechanisms 2 connected to the machine base 1, and a control unit, wherein the control unit is used to control the operation of the automatic material separation device 100.

[0033] Each of the material separation mechanisms 2 includes a driving assembly 21 installed on the machine base 1, a first plug block 22 and a second plug block 23 connected to the driving assembly 21, and the first plug block 22 and the second plug block 23 are used to be inserted between the material to be separated 10 and the remaining materials, so as to facilitate the subsequent separation of the material to be separated 10 from the remaining materials.

[0034] Specifically, the driving component 21 is configured to first drive the first plug block 22 and the second plug block 23 to be synchronously inserted between the material to be separated 10 and the remaining materials, and then drive the first plug block 22 to drive the material to be separated 10 to move away from the remaining materials to separate the material to be separated 10, so as to facilitate subsequent processing of the material to be separated 10, such as laser cutting.

[0035] Among them, at least two of the material dividing mechanisms 2 are arranged on opposite sides of the machine base 1. In the process that the driving component 21 drives the first plug-in block 22 to drive the material to be separated 10 to move in the direction away from the remaining materials, on the one hand, the first plug-in blocks 22 in the at least two material dividing mechanisms 2 located on the opposite sides respectively support the material to be separated 10 from the opposite sides of the material to be separated 10, so that the material to be separated 10 can be separated from the remaining materials and enhance the stability of the material to be separated 10 during the separation process; on the other hand, the second plug-in blocks 23 in the at least two material dividing mechanisms 2 located on the opposite sides respectively support the remaining materials from the opposite sides of the remaining materials to limit the movement of the remaining materials.

[0036] Of course, it is understandable that the specific installation positions of the at least two material dividing mechanisms 2 can be adjusted according to specific circumstances, such as according to the length of the material, etc.; it will not be repeated here.

[0037] In a specific embodiment, the driving assembly 21 includes a first cylinder 211 fixed on the base 1 , a second cylinder 212 connected to the first cylinder 211 , and the first plug block 22 and the second plug block 23 are both connected to the second cylinder 212 .

[0038] Specifically, the first cylinder 211 includes a first cylinder seat 2111 fixed on the machine base 1, and a first telescopic arm 2112 movably connected to the first cylinder seat 2111 and capable of being telescopically extended along the width direction of the material to be separated 10; the second cylinder 212 includes a second cylinder seat 2121 connected to the first telescopic arm 2112, and a second telescopic arm 2122 movably connected to the second cylinder seat 2121 and capable of being telescopically extended along the thickness direction of the material to be separated 10; the first plug block 22 is installed on the second telescopic arm 2122, and the second plug block 23 is installed on the second cylinder seat 2121.

[0039] When the first cylinder 211 is started, it can drive the second cylinder 212, and link the first insert block 22 and the second insert block 23 to move along the width direction of the material to be separated 10, so as to be inserted between the material to be separated 10 and the remaining materials from the gap between the material to be separated 10 and the remaining materials.

[0040] After the first cylinder 211 is started, the second cylinder 212 is started, and the second telescopic arm 2122 is telescopic to drive the first plug block 22 to move along the thickness direction of the material to be separated 10 in a direction away from the remaining materials, that is, the second telescopic arm 2122 is telescopic to drive the first plug block 22 to move upward to separate the material to be separated 10 from the remaining materials. At the same time, when the second cylinder 212 is started, the first cylinder 211 is stopped to keep the second plug block 23 stationary, so that the second plug block 23 is abutted against the remaining materials to limit the movement of the remaining materials with the material to be separated 10.

[0041] Furthermore, the first plug block 22 and the second plug block 23 both have a connecting portion, an insertion portion connected to the connecting portion and used to be inserted between the material 10 to be separated and the remaining materials, and the thickness of the insertion portion gradually decreases along the extension direction of the insertion portion, thereby facilitating the first plug block 22 and the second plug block 23 to be inserted between the material 10 to be separated and the remaining materials from the gap between adjacent materials 10.

[0042] Specifically, the first plug block 22 has a first connecting portion 221 connected to the second telescopic arm 2122 and a first inserting portion 222 connected to the first connecting portion 221. The upper surface of the first inserting portion 222 is provided with a supporting surface 2221 for supporting the material to be separated 10, thereby increasing the contact area between the first plug block 22 and the material to be separated 10 and enhancing the supporting stability of the first plug block 22 on the material to be separated 10.

[0043] The second plug block 23 has a second connecting portion 231 connected to the second cylinder seat 2121 and a second inserting portion 232 connected to the second connecting portion 231. The lower surface of the second inserting portion 232 is provided with a supporting surface 2321 for supporting against the remaining parts, thereby enhancing the contact area between the second plug block 23 and the remaining parts.

[0044] Furthermore, the automatic material separation device 100 also includes a monitoring mechanism 3 for monitoring the number of materials 10 grabbed by the material separation mechanism 2 to prevent the material separation mechanism 2 from separating multiple materials 10 at a time and affecting the implementation of subsequent processing processes.

[0045] Furthermore, the automatic material separation device 100 also includes a driving mechanism (not shown) for driving the machine base 1 to move along the thickness direction of the material 10, that is, driving the base 1 to move in the up and down directions. It can be understood that when the driving mechanism drives the base 1 to move downward, it can drive the separating mechanism 2 to move downward as a whole, so that the first plug block 22 and the second plug block 23 can be aligned with the gap between the material to be separated 10 and the remaining materials, so as to facilitate the subsequent separation of the material to be separated 10 from the remaining materials by the separating mechanism 2.

[0046] The monitoring mechanism 3 includes a fixed plate 31 fixed to the machine base 1, a movable rod 32 movably connected to the fixed plate 31 along the thickness direction of the material 10, and a first position sensor 33 provided on the fixed plate 31 to sense the position of the movable rod 32, that is, the movable rod 32 is movably connected to the fixed plate 31 along the up and down direction, and when the driving mechanism drives the base 1 to move downward until the first plug block 22 and the second plug block 23 are aligned with the gap between one of the material pieces 10 to be separated and the other material pieces, the movable rod 32 touches one end of the material piece 10 toward the For the material piece 10 to be separated, if the driving mechanism drives the base 1 to continue to descend, the movable rod 32 moves upward, and the first position sensor 33 senses the position signal of the movable rod 32 moving upward and feeds back to the control unit. The control unit determines that the base 1 moves downward excessively, controls the driving mechanism to stop driving the base 1 to move downward and drives the base 1 to move upward a preset distance, so that the first plug block 22 and the second plug block 23 can be aligned with the gap between one of the material pieces 10 to be separated and the remaining material pieces, ensuring that the material separation mechanism 2 separates only one of the material pieces 10 at a time.

[0047] Specifically, a through hole is provided on the fixing plate 31, and the movable rod 32 is movably connected in the through hole, and limit blocks 321 are provided at opposite ends of the movable rod 32. The outer diameter of the limit blocks 321 is larger than the aperture of the through hole to prevent the movable rod 32 from escaping from the through hole.

[0048] The monitoring mechanism 3 also includes a spring 34 mounted on the movable rod 32, one end of the spring 34 abuts against the lower side of the fixed plate 31, and the other end abuts against the limit block 321 located at the lower end, so that the movable rod 32 can be maintained at the initial position, that is, the movable rod 32 will only move upward when it is subjected to an upward force applied by the material 10, and at this time, the spring 34 is in a compressed state.

[0049] Furthermore, the automatic material separation device 100 also includes a limit member 4, and the limit member 4 is used to limit the distance that the first plug block 22 drives the material 10 to be separated to move, that is, after the second cylinder 212 starts to drive the first plug block 22 to move upward until the material 10 to be separated touches the limit member 4, the second cylinder 212 is controlled to stop. At this time, the separation between the material 10 to be separated and the remaining materials is completed.

[0050] In a specific implementation, the limiting member 4 is rod-shaped, and the limiting member 4 is fixed on the first cylinder seat 2111; of course, this is not limited to this.

[0051] Furthermore, the monitoring mechanism 3 includes a second position sensor (not shown) disposed in the second cylinder seat 2121 and used to sense the retracted position of the second telescopic arm 2122. It is understandable that if the first plug block 22 drives multiple materials 10 to move upward, after the material 10 located at the uppermost side touches the limiter 4 to stop, the second telescopic arm 2122 cannot be retracted into place, and after the second position sensor feeds back the information that the second telescopic arm 2122 cannot be retracted into place to the control unit, the control unit determines that the material separation mechanism 2 has separated multiple materials 10 and feeds back to the user.

[0052] It is understandable that after the first position sensor fails, the second position sensor can be used to monitor the number of materials separated by the material separation mechanism 2 to ensure that the material separation mechanism 2 separates only one material.

[0053] After the automatic material separation device 100 completes the separation between the material 10 to be separated and the remaining materials, the separated material 10 is placed on a laser cutting fixture for laser processing. It can be understood that the laser processing includes cutting and drilling, that is, cutting the material 10 into a valid part and a waste part, and drilling a hole in the valid part to form a plug hole. Of course, this is not limited to this.

[0054] Furthermore, the automatic material separation device 100 also includes a waste separation mechanism 5, and the waste separation mechanism 5 includes a first grasping mechanism 51 for grasping the effective part and a second grasping mechanism 52 for grasping the waste part. After the laser processing of the material 10 is completed, the automatic material separation device 100 grasps the effective part and the waste part, and moves the whole to the waste collection box, and then the second grasping mechanism 52 places the waste part in the waste collection box, thereby completing the separation between the effective part and the waste part.

[0055] In a specific embodiment, the waste separation mechanism 5 includes a fixed seat fixed on the machine base 1, a driving member (not shown) driving the first grabbing mechanism 51 and the second grabbing mechanism 52, the first grabbing mechanism 51 includes a plug 511 movably connected to the fixed seat along the width direction of the material 10, the position of the plug 511 corresponds to the position of the plug hole, it can be understood that the number of the plug 511 is multiple, and at least two of the plugs 511 are arranged on opposite sides of the material 10, the driving member drives the multiple plugs 511 to move outward so that the plugs 511 can be inserted into the plug hole to achieve the grabbing of the effective part, and the plug 511 grabs the laser-processed material 10, which can prevent the material separation mechanism 2 from interfering with the laser cutting during the grabbing process. Of course, it is not limited to this.

[0056] In a specific embodiment, the second gripping mechanism 52 is a vacuum suction cup mechanism, that is, the second gripping mechanism 52 includes a magnetic suction cup and a vacuum pump for drawing a vacuum. When grabbing the waste portion, the vacuum pump draws a vacuum, so that the magnetic suction cup absorbs the waste portion, and the material 10 is moved as a whole to the waste collection box. Then, the magnetic suction cup is cut off, and the waste portion is placed in the waste collection box, thereby completing the separation between the effective portion and the waste portion.

[0057] The material separation mechanism 2 in the automatic material separation device 100 of the present invention is provided with a first plug block 22 for driving the material 10 to be separated to move and a second plug block 23 for abutting against the remaining materials, so as to achieve separation between adjacent or closely fitting materials 10. The structure is simple and stable, and it breaks through the limitation of the vacuum grasping of the material 10 on the shape of the material 10. It has strong versatility and avoids the problem of the material 10 falling off during the movement due to grasping multiple closely fitting materials 10. It is safer and more reliable.

[0058] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
