Description

Technical Field

[0001] This application relates to the field of automated production equipment technology, specifically to an air-blowing splitting device and a destacking system including the air-blowing splitting device. Background Technology

[0002] The vehicle has numerous stamped parts made from sheet metal cut from sheet metal. Multiple sheets are stacked together and transported to the stamping production line via pallets. A splitting system separates the sheets one by one and transports them to subsequent workstations. When the sheet metal is aluminum, high-pressure gas is typically used to blow directly onto the top layer of sheet metal from one side, creating a gap between it and the lower aluminum sheets. This allows the sheet metal to be gripped by suction cups or grippers and transported away, thus achieving the individual splitting and transport of the sheets. However, each sheet is coated with lubricating oil, and the gaps between adjacent sheets are very small, resulting in a certain degree of adhesion between adjacent sheets, making them difficult to separate. Furthermore, as the sheet stack is split, it is difficult to ensure that the top sheet is precisely aligned with the air outlet and in the highest pressure airflow area when the stack and air knife are adjusted. This leads to difficulties in splitting, or the phenomenon that two or three sheets are still tightly stacked and split together. A detection system or personnel monitoring is required to prevent this phenomenon from damaging subsequent operations and requires rework and re-splitting, which seriously affects production efficiency. Utility Model Content

[0003] In view of this, this application aims to provide an air-blowing splitting device that can effectively improve the phenomenon of splitting multiple sheets of material together and achieve high-precision splitting of each sheet of material.

[0004] This application mainly provides an air-blowing splitting device, including:

[0005] An air knife is provided with an air chamber. The air inlet of the air chamber is used to connect an air source, and the air outlet includes a plurality of uniformly spaced air holes, so that the arrangement direction of the plurality of air holes is consistent with the stacking direction of the sheet metal.

[0006] The mounting base connects to and secures the air knife, and is equipped with an angle adjustment mechanism to adjust the air knife's blowing angle.

[0007] In one possible implementation, the angle adjustment mechanism includes:

[0008] A first rotating shaft connects the air knife and the mounting base, so that the air knife and the mounting base are rotatably connected;

[0009] The first locking element locks the first rotating shaft or the air knife onto the mounting base.

[0010] In one possible implementation, the first locking member is a first threaded sleeve that is sleeved on the first rotating shaft and threadedly connected to the first rotating shaft.

[0011] And / or, the hole on the mounting base or the air knife through which the first rotating shaft passes is a first strip hole, and the length direction of the first strip hole is consistent with the arrangement direction of the plurality of air blowing holes.

[0012] In one possible implementation, the angle adjustment mechanism further includes an adjustment bolt, which is threadedly connected to the air knife or the mounting base and is used to push against the air knife to make the air knife rotate around the first rotating shaft.

[0013] In one possible implementation, the angle adjustment mechanism further includes an adjustment block, one end of the adjustment bolt is threadedly connected to the air knife and the other end is threadedly connected to the adjustment block, the adjustment block is rotatably connected to the mounting base via a second rotating shaft and can be locked onto the mounting base via a second locking member, and the hole on the adjustment block through which the second rotating shaft passes is a second strip hole.

[0014] In one possible implementation, the second locking member is a second threaded sleeve sleeved on the second rotating shaft and threadedly connected to the second rotating shaft, the second threaded sleeve being used to press the adjusting block against the mounting base.

[0015] In one possible implementation, the diameter of the air inlet is 0.8-1.2 mm;

[0016] And / or, the axial distance between the centers of two adjacent air holes is 1.8-2.2 mm;

[0017] And / or, the number of air holes in the same column is 15-25;

[0018] And / or, the air inlet includes a plurality of air inlets evenly spaced apart, one of the air inlets being correspondingly provided with one or a portion of the air blowing holes, and the axial projection of the corresponding air blowing holes at least partially coincides.

[0019] This application also provides a destacking system, including a pallet supporting the sheet metal, a gripping mechanism for gripping the sheet metal, and an air-blowing splitting device as described in any of the preceding claims.

[0020] In one possible implementation, a lifting mechanism is also included to raise and lower the pallet, thereby adjusting the relative height between the uppermost sheet and the air knife.

[0021] The air-blowing splitting device provided in this application has an air outlet on the air knife that is not a single opening, but includes multiple air holes arranged at intervals, which increases the air blowing range and ensures that the air pressure of the air blown out by each air hole is uniform. It also ensures that the multiple air holes are aligned with the stacking direction of the sheet material, so that the multiple uniformly distributed airflows are vertically arranged and stably blown towards the sheet material. This makes it easy to achieve precise alignment between the top sheet material and the air outlet, ensuring that the top sheet material is within the high-pressure blowing range of the airflow. At the same time, the air knife can be adjusted to blow air onto the sheet material at a slightly upturned angle, that is, the airflow blows the sheet material obliquely upward, eliminating the downward pressure component of the airflow above the top sheet material on the top sheet material, and also maximizing the blowing force on the top sheet material, thereby ensuring that the sheet material can be effectively split and split one layer at a time.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please refer to the attached document. Figures 1-4This application provides an air-blowing splitting device, which includes a mounting base 4 and an air knife 1 connected to the mounting base 4. The air knife 1 is provided with an air chamber and an air inlet and an air outlet communicating with the air chamber. The air inlet of the air chamber is used to connect to an air source, and the air outlet is used to blow gas outward. The air outlet includes a plurality of evenly spaced blowing holes 11, which form one or more vertical rows. When facing the sheet metal stack 2, the arrangement direction of the plurality of blowing holes 11 is consistent with the height direction of the sheet metal stack 2 and the stacking direction of each sheet. This increases the airflow range blown from the air outlet onto the sheet metal. Moreover, since it is blowing air through multiple small holes rather than a single large opening, it can ensure that the pressure of each blowing hole 11 is relatively large and uniform, and there is no large pressure difference between local airflow pressures and local pressures. Multiple uniform airflows are arranged vertically to form a large-area uniform high-pressure blowing area. As the stacking process proceeds, it ensures that each top layer of sheet material 21 is precisely aligned with the air outlet and is within the high-pressure, full-pressure blowing zone.

[0030] Meanwhile, the mounting base 4 is equipped with an angle adjustment mechanism for adjusting the angle of the air knife 1, which can adjust the blowing angle of the air knife 1. Thus, the air knife 1 can form an angle relative to the sheet metal, causing the air knife 1 to blow air onto the sheet metal at a slightly upturned angle, i.e. Figure 1 As shown, the airflow blows the sheet metal obliquely upward, eliminating the downward pressure component of the airflow above the top sheet metal 21 on the top sheet metal 21. The other sheets metal that are also blown apart will be subjected to the downward pressure of the airflow entering the gap above them. For example, a gap will also be generated between the second sheet metal and the top sheet metal 21. The airflow entering the gap will be blocked by the top sheet metal and turned back downward, thus exerting downward pressure on the second sheet metal. It can be seen that the air knife 1 blowing obliquely upward can maximize the blowing force on the top sheet metal 21, thereby ensuring that each sheet metal in the sheet metal pile 2 can be effectively separated and separated one by one layer.

[0031] As can be seen, the air-blowing splitting device provided in this application, by adjusting the structure of the air outlet and the air-blowing angle, enables multiple evenly distributed airflows with uniform air pressure to be arranged vertically and blown stably onto the sheet material. This makes it easy to achieve precise alignment between the uppermost sheet material 21 and the air outlet, ensuring that the uppermost sheet material 21 is within the high-pressure blowing range of the airflow. At the same time, it enables the air knife 1 to always blow the uppermost sheet material 21 with high pressure and sufficient pressure, ensuring that the sheet material is split into individual layers one by one, which can also improve the sheet material splitting efficiency to a certain extent.

[0032] For aluminum sheets with a general thickness of 0.8-1.2 mm, the diameter of the air blowing hole 11 is preferably 0.8-1.2 mm; the axial distance between the centers of two adjacent air blowing holes 11 (the axial distance between the centers or central axes of the two holes) is 1.8-2.2 mm. This setting ensures excellent sheet separation effect.

[0033] The number of air holes 11 in the same column can be 15-25; this ensures a certain effective blowing range and precise alignment between the uppermost sheet 21 and the effective blowing range. For example, when the number of air holes 11 in the same column is 19, the effective blowing range or sheet separation range it covers can reach 30 mm. As long as the uppermost sheet 21 is within this 30 mm height range, it can be effectively sheeted into a single layer.

[0034] The air chamber can be a strip-shaped cavity extending in the same direction as the arrangement of multiple air holes 11, with an air inlet at one end or one side to connect to a high-pressure air source. The air inlet can be an integral opening connected to the high-pressure air source via a pipeline. The size of the air inlet is set according to the number of air holes 11 to ensure the pressure of the airflow blown out by each air hole 11. Alternatively, the air inlet includes multiple air holes evenly spaced apart, with one air hole corresponding to one or a portion of the air holes 11, and the axial projection of the air hole at least partially coinciding with the corresponding air hole 11. In this way, the multiple holes in the air inlet can help improve the uniformity of air pressure among the air holes 11.

[0035] To facilitate angle adjustment, the air knife 1 and the mounting base 4 are rotatably connected. The angle adjustment mechanism includes a first rotating shaft 5 and a first locking member 9. The first rotating shaft 5 passes through the air knife 1 and the mounting base 4, allowing the air knife 1 to be rotatably connected to the mounting base 4. The first locking member 9 is used to lock the first rotating shaft 5 or the air knife 1 onto the mounting base 4. In this way, the air knife 1 can be manually rotated or rotated through other components to move the lower end of the air knife 1 closer to or further away from the sheet metal, thereby adjusting the blowing angle of the air knife 1 relative to the sheet metal. Then, the air knife 1 can be securely locked at that angle.

[0036] Specifically, the first locking element 9 is a threaded sleeve that is fitted onto and threadedly connected to the first rotating shaft 5. The threaded sleeve is used to press the air knife 1 against the mounting base 4. Preferably, the first rotating shaft 5 can be a first bolt, and the first locking element 9 is a first nut fitted onto the first bolt. The holes on the air knife 1 and the mounting base 4 through which the first bolt passes are open holes, meaning that the first bolt is not threadedly connected to either the air knife 1 or the mounting base 4. Thus, by loosening the first nut, the air knife 1 can rotate relative to the mounting base 4, allowing the angle of the air knife 1 to be adjusted. After adjustment, tightening the first nut, which clamps the air knife 1 and the mounting base 4 together with the first bolt, locks the air knife 1. This allows for a very simple locking operation of the air knife 1.

[0037] like Figure 2 and Figure 3As shown, the hole on the mounting base 4 or the air knife 1 through which the first rotating shaft 5 passes can be a first strip hole 101. This allows for adjustment of the position of the air knife 1 on the mounting base 4. Preferably, the length direction of the first strip hole 101 is consistent with the arrangement direction of the plurality of air holes 11, thus enabling adjustment of the height position of the air knife 1 relative to the sheet metal stack 2, facilitating responses to various production conditions and making it easier to ensure the height alignment of the uppermost sheet metal 21 and the air outlet of the air knife 1. The first strip hole 101 can also be a stepped hole, having a stepped groove to accommodate the bolt cap of the first bolt.

[0038] like Figure 2 As shown, in some embodiments, the angle adjustment mechanism further includes an adjustment bolt 6, which is threadedly connected to the air knife 1 or the mounting base 4 and is used to push the air knife 1 so that the air knife 1 rotates around the first rotating shaft 5.

[0039] For example, the adjusting bolt 6 is threaded to one of the air knife 1 and the mounting base 4, and abuts against the other; when the adjusting bolt 6 is rotated, the air knife 1 can rotate relative to the mounting base 4. Connecting the adjusting bolt 6 to the end of the air knife 1 away from the first rotating shaft 5, for example, the first rotating shaft 5 is located at the top of the air knife 1 and the adjusting bolt 6 is connected to the bottom end of the air knife 1, and screwing the adjusting bolt 6 out of the air knife 1 or the mounting base 4 connected to it, increases its length between the air knife 1 and the mounting base 4, which can push the bottom end of the air knife 1 to deflect it, causing the air knife 1 to tilt as a whole, and each air hole 11 tilts upward to blow airflow.

[0040] Alternatively, the angle adjustment mechanism may include an adjustment block 7 in addition to the adjustment bolt 6; one end of the adjustment bolt 6 is threaded to the air knife 1 and the other end is threaded to the adjustment block 7, while the adjustment block 7 is rotatably connected to the mounting base 4 via the second rotating shaft 8 and can be locked onto the mounting base 4 via the second locking member 10. The hole on the mounting base 4 through which the second rotating shaft 8 passes is a second strip hole 701.

[0041] Thus, when the adjusting bolt 6 is turned, the air knife 1 can rotate relative to the mounting base 4. At the same time, due to the setting of the second strip hole 701, the adjusting block 7 can adjust its position relative to the mounting base 4 with the adjusting bolt 6, preventing the movement of the adjusting bolt 6 from being blocked. After the adjustment is completed, the adjusting block 7 is fixed, and the other end of the adjusting bolt 6 can also be firmly connected to the mounting base 4. The air knife 1 is locked on the mounting base 4 through two fastening points, ensuring that the air knife 1 can be firmly fixed after the angle is adjusted, preventing the air knife 1 from shaking or deflecting and affecting the alignment accuracy with the sheet metal.

[0042] Specifically, the second locking element 10 is a second threaded sleeve that is fitted onto and threadedly connected to the second rotating shaft 8. The second threaded sleeve is used to press the adjusting block 7 against the mounting base 4. Preferably, the second rotating shaft 8 is a second bolt, the hole on the mounting base 4 through which the second rotating shaft 8 passes is a smooth hole, and the second locking element 10 is a second nut fitted onto the second bolt. Thus, by loosening the second nut, the angle of the air knife 1 can be adjusted; by tightening the second nut, the adjusting block 7 is locked and pressed against the mounting base 4. Combined with the locking and pressing of the air knife 1 by the first locking element 9, the air knife 1 can be securely fixed to the mounting base 4.

[0043] The second slot 701 can also be a stepped hole, having a stepped groove for receiving the bolt cap of the second bolt.

[0044] Of course, besides adjusting the spiral structure, the angle of the air knife 1 can also be adjusted using other structures, such as a worm gear structure. A worm can be connected to the air knife 1, and the worm gear can be rotatably mounted on the mounting base 4, with the spiral angle of the worm being smaller than the friction angle of the worm gear contact (the condition for self-locking in worm gear transmission). In this way, the rotation of the worm can adjust the angle of the air knife 1 relative to the mounting base 4, and after the angle is adjusted, the air knife 1 can be locked by self-locking to prevent the air knife 1 from shaking and causing angle deviation.

[0045] Embodiments of this application also provide a destacking system, which includes a pallet 3 supporting the sheet metal, a gripping mechanism for gripping the sheet metal, and an air-blowing splitting device as described in any of the above embodiments. Thus, the destacking system has the structure and beneficial effects described in the above embodiments, which will not be repeated here.

[0046] The destacking system also includes a lifting mechanism that raises and lowers the pallet 3 to adjust the relative height between the uppermost sheet 21 and the air knife 1. The ability to raise or lower either the air knife 1 or the pallet 3 allows for adjustment of their relative height. This simplifies pallet 3 raising and lowering and prevents excessive vibration from frequent movement of the air knife 1, which could lead to loosening of the air knife 1 or changes in the air blowing angle.

[0047] Furthermore, it also includes a controller and a detector for detecting the height position of the uppermost sheet 21. The controller adjusts the lifting mechanism based on the signal from the detector. In this way, the height position of the uppermost sheet 21 is precisely controlled so that it is accurately within the effective slitting range of the air knife 1.

[0048] Specifically, the lifting mechanism may include a support arm comprising a support tray 3 and a power component, the power component being a hydraulic cylinder; the support arm is a telescopic arm, which may comprise multiple sequentially hinged links.

[0049] The detector can be a photoelectric sensor or an infrared sensor, etc., and can be positioned at the same height as the air outlet of the air knife 1. When the top layer of sheet material 21 moves to this height, the detector is triggered, causing the controller to shut off the lifting mechanism, keeping the top layer of sheet material 21 at that height. When the top layer of sheet material 21 is removed, and there is no sheet material at the position opposite the detector, the detector signal changes, and the controller activates the lifting mechanism to lift the tray 3. The original second layer of sheet material becomes the new top layer of sheet material 21. When the new top layer of sheet material 21 moves to the height position directly opposite the air outlet of the air knife 1, the detector is triggered again. This cycle ensures that each sheet material can be effectively separated one by one.
