Description

Technical Field

[0001] This application relates to the field of sheet-splitting equipment technology, specifically to a handheld sheet-splitting device, a sheet-splitting mechanism, and a stamping production line. Background Technology

[0002] In automated stamping production lines in the automotive industry, thin steel sheets are stacked and placed in piles. The sheets are picked up layer by layer by gripping mechanisms such as robotic arms and moved to the stamping mechanism for stamping operations. In order to avoid the sheets sticking together, the gripping mechanism is prone to problems such as material sticking, material falling, and misalignment during the gripping process, which seriously affects production efficiency and product quality.

[0003] To address this issue, magnetic sheet separation devices are typically used. These devices utilize the principle of repulsion between like magnetic poles to separate adjacent sheets, preventing issues such as material sticking together or double-sheet material. Effective sheet separation also solves problems like material dropping and misalignment. Handheld sheet separators offer greater flexibility, but existing handheld sheet separators are usually designed to be complex, heavy, inconvenient for manual operation and handling, and costly.

[0004] How to provide a handheld sheet separator that is simple in structure, lightweight, easy for operators to operate and carry, and can effectively reduce costs is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a handheld sheet separator, a sheet separator mechanism, and a stamping production line. The handheld sheet separator has a simple structure, is lightweight, is easy to operate and handle manually, and can effectively reduce costs. The handheld sheet separator provides an effective sheet separator function, avoiding situations such as material carrying, material dropping, or misalignment during the gripping process, thereby ensuring production efficiency and product quality.

[0006] To solve the above-mentioned technical problems, this application provides a handheld sheet separator, including a first magnetic head, a connecting rod, and a counterweight; one end of the connecting rod is connected to the first magnetic head, and the other end of the connecting rod is connected to the counterweight; along a first direction, the bottom end of the first magnetic head protrudes beyond the bottom end of the counterweight, or the bottom end of the first magnetic head is aligned with the bottom end of the counterweight.

[0007] Optionally, the end of the connecting rod connected to the first magnetic head is spaced at a preset distance from the bottom end of the first magnetic head along a first direction to form a handle.

[0008] Optionally, the first magnetic head includes at least two magnets, which are stacked and connected to each other along a first direction.

[0009] Optionally, the first magnetic head further includes a housing, each of the magnets is disposed inside the housing, and the housing is connected to the connecting rod.

[0010] Optionally, the connecting rod is welded to the first magnetic head, and / or the connecting rod is welded to the counterweight.

[0011] This application also provides a sheet separation mechanism, including a base and a handheld sheet separator as described above. The base is provided with a sheet material placement area, and the handheld sheet separator is located around the sheet material placement area.

[0012] Optionally, it also includes a magnetic separator and a support, the support being disposed around the periphery of the sheet placement area, the magnetic separator including a driving part and a second magnetic head disposed on the support, the driving part being used to drive the second magnetic head to move closer to or further away from the sheet placed in the sheet placement area.

[0013] Optionally, it also includes a lifting unit for driving the base to move relative to the magnetic fixing seat in a first direction.

[0014] Optionally, the base may also have a hollow structure.

[0015] This application also provides a stamping production line, including the sheet-splitting mechanism described above.

[0016] The purpose of this application is to provide a handheld sheet separator, a sheet separator mechanism, and a stamping production line, which, compared with the prior art, have the following technical advantages:

[0017] In use, the first magnetic head of the handheld sheet divider is attached to the side wall of the stack of sheets. That is, the first magnetic head is attached to the side wall of multiple sheets at the same time. The attraction force is greater than the overall weight of the handheld sheet divider, so that the handheld sheet divider is attached and fixed to the side of the stack of sheets. As the gripping mechanism grips the sheets, the number of sheets attached to the first magnetic head decreases. When the weight of the handheld sheet divider is greater than the attraction force, the handheld sheet divider will fall under the action of gravity. As it falls, the handheld sheet divider is attached to the sheet below. When the attraction force and gravity are balanced, the position of the handheld sheet divider stabilizes again and continues to divide the sheet above.

[0018] As the gripping mechanism grips the sheet material, the remaining amount of sheet material gradually decreases, and the first magnetic head gradually falls. Since the bottom end of the counterweight does not extend downwards beyond the bottom end of the first magnetic head, the first magnetic head can fall to its bottom end and abut against the base without being affected by the counterweight. This ensures that the first magnetic head can provide magnetic attraction for the sheet material at the bottom, thereby ensuring that the sheet material at the bottom can be effectively separated.

[0019] Furthermore, when the number of remaining sheets in the sheet placement area is small, the first magnetic head is prone to tilting to one side of the sheet due to the attraction between it and the sheet. The counterweight and connecting rod can provide a pulling force to the first magnetic head from the side away from the sheet, preventing the first magnetic head from tilting to one side of the sheet. This ensures that the first magnetic head can provide a stable sheet separation function, and also prevents the first magnetic head from tilting onto the surface of the sheet, making it impossible for the gripping mechanism to grip the sheet.

[0020] In other words, the handheld sheet separator provided in this application, as the gripping mechanism grasps the sheet material, falls under the influence of gravity until it lands on the base. A counterweight ensures the stability of the first magnetic head and prevents tipping, thus ensuring smooth sheet material gripping. Furthermore, because the handheld sheet separator is flexible in its position and can be set according to the actual shape and specifications of the sheet material, it provides effective sheet material separation, preventing issues such as material dragging, falling, or misalignment during gripping, thereby ensuring production efficiency and product quality. This handheld sheet separator only requires initial setup by an operator to attach and fix the first magnetic head to the sheet material; during production, no manual operation is required, reducing reliance on specialized technicians and simplifying operation.

[0021] The handheld sheet separator has a simple overall structure, eliminating the need for a magnetic fixing base. Furthermore, since the handheld sheet separator does not require high positional accuracy during use, there is no need for guide rods or other components to guide the descent of the first magnetic head. Therefore, compared to existing technologies that use magnetic fixing bases and / or guide rods to guide the movement of the magnets, the handheld sheet separator provided in this application simplifies the overall structure, effectively reduces overall weight, facilitates manual handling, and is less costly. Moreover, when removing the handheld sheet separator from the base after sheet material gripping, the force required to remove it is greatly reduced because there is no need to overcome the magnetic attraction between the magnetic fixing base and the base, facilitating operation. Additionally, the absence of guide rods avoids interference with the gripping mechanism's movement, simplifying the gripping mechanism's path design. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This application provides a handheld sheet separator, a sheet separation mechanism, and a stamping production line. The stamping production line includes a sheet separation mechanism, a gripping mechanism, and a stamping mechanism located downstream. The sheet separation mechanism is located at the beginning of the line and is used to separate stacked sheet materials 3. The gripping mechanism can move a single sheet material 3 from the sheet separation mechanism to the stamping mechanism located downstream for stamping operation.

[0033] like Figure 1 and Figure 2 As shown, the sheet-splitting mechanism includes a base 2 and a handheld sheet-splitter 1. The base 2 is provided with a sheet material placement area for placing sheet materials 3. Multiple sheet materials 3 are stacked sequentially in the sheet material placement area along a first direction to form a stack. The first direction refers to the height direction of the stacked sheet materials 3. The handheld sheet-splitter 1 is located on the periphery of the sheet material placement area and provides a magnetic force to the sheet materials 3 from the side, so that adjacent layers of sheet materials 3 are repelled by the same magnetic poles and move away from each other, thereby achieving the effect of sheet-splitting. When the gripping mechanism grips the top sheet material 3, it avoids the situation of material being carried along or double material. Since the sheet materials 3 are effectively split, it can also avoid the situation of material falling or gripping off-center during the gripping process, reducing the probability of machine downtime due to malfunction, thereby ensuring production efficiency and product quality.

[0034] Specifically, such as Figure 3 As shown, the handheld sheet separator 1 includes a first magnetic head 11, a connecting rod 12, and a counterweight 13. One end of the connecting rod 12 is connected to the first magnetic head 11, and the other end of the connecting rod 12 is connected to the counterweight 13. Along a first direction, the bottom end of the first magnetic head 11 protrudes beyond the bottom end of the counterweight 13, or the bottom end of the first magnetic head 11 is aligned with the bottom end of the counterweight 13. That is to say, the bottom end of the counterweight 13 does not extend downward beyond the bottom end of the first magnetic head 11.

[0035] The first magnetic head 11 has an adsorption surface 113 formed on the side face away from the counterweight 13. In use, the adsorption surface 113 is attached to the side wall of the stack. The projection of the bottom end of the counterweight 13 along the first direction onto the adsorption surface is located within the adsorption surface 113, so that the bottom end of the counterweight 13 does not extend beyond the bottom end of the first magnetic head 11.

[0036] In use, the first magnetic head 11 of the handheld sheet divider 1 has its adsorption surface 113 facing the stack of materials and adsorbing onto the side wall of the stack. That is, the first magnetic head 11 is simultaneously adsorbed onto the side wall of multiple sheets 3. The adsorption force is greater than the overall weight of the handheld sheet divider 1, so that the handheld sheet divider 1 is adsorbed and fixed on the side of the stack of materials. As the gripping mechanism grips the sheet 3, the number of sheet 3 adsorbed by the first magnetic head 11 decreases. When the weight of the handheld sheet divider 1 is greater than the adsorption force, the handheld sheet divider 1 will fall under the action of gravity. As it falls, the handheld sheet divider 1 adsorbs onto the sheet 3 located below. When the adsorption force and gravity are balanced, the position of the handheld sheet divider 1 stabilizes again and continues to divide the sheet 3 located above.

[0037] As the gripping mechanism grips the sheet material 3, the remaining quantity of sheet material 3 gradually decreases, and the first magnetic head 11 gradually falls. Since the bottom end of the counterweight 13 does not extend downwards beyond the bottom end of the first magnetic head 11, the first magnetic head 11 can fall to its bottom end and abut against the base 2 without being affected by the counterweight 13. This ensures that the first magnetic head 11 can provide magnetic adsorption for the sheet material 3 located at the bottom, thereby ensuring that the sheet material 3 located at the bottom can be effectively separated.

[0038] Furthermore, when the number of remaining sheets 3 in the sheet placement area is small, the first magnetic head 11 is prone to tilting to one side of the sheet 3 due to the attraction between it and the sheet 3. The counterweight and connecting rod 12 can provide a pulling force to the first magnetic head 11 from the side away from the sheet 3, preventing the first magnetic head 11 from tilting to one side of the sheet 3. This ensures that the first magnetic head 11 can provide a stable sheet separation function for the sheet 3, and also prevents the first magnetic head 11 from tilting onto the surface of the sheet 3, making it impossible for the gripping mechanism to grip the sheet 3.

[0039] In other words, the handheld sheet separator 1 provided in this embodiment, as the gripping mechanism grips the sheet material 3, falls under the action of gravity until it lands on the base 2. The counterweight 13 ensures the stability of the first magnetic head 11 and prevents it from tipping over, thus ensuring smooth gripping of the sheet material 3. Furthermore, since the handheld sheet separator 1 is flexible in its position, it can be set according to the actual shape and specifications of the sheet material 3. By providing effective sheet separation for the sheet material 3, the handheld sheet separator 1 can prevent issues such as material dragging, falling, or misalignment during gripping, thereby ensuring production efficiency and product quality. The handheld sheet separator 1 only requires the operator to attach and fix its first magnetic head 11 to the sheet material 3 during initial use. During production, no manual operation is required, reducing reliance on specialized technicians and simplifying operation.

[0040] The handheld sheet separator 1 has a simple overall structure, eliminating the need for a magnetic fixing base to secure it to the base 2. Furthermore, since the handheld sheet separator 1 does not require high positional accuracy during use, there is no need for guide rods or other components to guide the descent of the first magnetic head 11. Therefore, compared to existing technologies that use magnetic fixing bases to attach to the base 2 and / or guide rods to guide the movement of the magnet 111, the handheld sheet separator 1 provided in this embodiment simplifies the overall structure, effectively reduces the overall weight, facilitates manual handling, and is less expensive. Moreover, when the sheet 3 is gripped and the handheld sheet separator 1 is removed from the base 2, the force required to remove it is greatly reduced because there is no need to overcome the magnetic attraction between the magnetic fixing base and the base 2, making operation easier. Additionally, the absence of guide rods avoids interference with the movement of the gripping mechanism, simplifying the path design of the gripping mechanism.

[0041] In addition, in this embodiment, there are no restrictions on the length of the connecting rod 12 and the size and weight of the counterweight 13. They can be set according to the actual situation. This ensures the stability of the handheld sheet divider 1 when there is a sufficient amount of sheet material 3 and the first magnetic head 11 is adsorbed on the side wall of the sheet material 3. At the same time, when the number of sheet materials 3 is small, the first magnetic head 11 can be prevented from tilting to one side of the sheet material 3 by the action of the counterweight 13 and the connecting rod 12.

[0042] like Figure 3 As shown, a preset distance H is left between the end of the connecting rod 12 connected to the first magnetic head 11 and the bottom end of the first magnetic head 11 along the first direction. That is to say, the connecting rod 12 is connected to the first magnetic head 11 at a certain height, but not to the bottom end of the first magnetic head 11. With this setting, when the first magnetic head 11 falls to abut against the base 2, there is still a certain distance between the connecting rod 12 and the base 2, and it does not fit against the base 2. The connecting rod 12 forms a handle, and the operator can pick up and put down the handheld sheet separator 1 through the connecting rod 12.

[0043] Of course, in this embodiment, the connecting rod 12 can simply serve as a connection between the first magnetic head 11 and the counterweight, while a handle component connected to the first magnetic head 11 can also be provided. When the connecting rod 12 serves as both a connector and a handle, the overall structure can be simplified, the overall weight reduced, and the cost effectively lowered. In addition, since the connecting rod 12 is connected to the first magnetic head 11 at a certain height, the counterweight is connected to the end of the connecting rod 12 away from the first magnetic head 11. Compared to the solution of connecting the connecting rod 12 to the bottom of the first magnetic head 11, the counterweight can better exert its counterweight function. That is to say, while achieving the same counterweight effect to prevent the first magnetic head 11 from tilting to one side of the sheet 3, the weight of the counterweight part 13 can also be reduced, thereby effectively reducing costs and facilitating handheld operation.

[0044] In this embodiment, the specific structure of the connecting rod 12 is not limited, such as... Figure 3 As shown, the axis of the connecting rod 12 is a straight line, which simplifies the structure of the connecting rod 12 and facilitates the selection of materials for the connecting rod 12. The connecting rod 12 can be a tubular structure or a rod structure. Furthermore, the cross-section of the connecting rod 12 can be a circular structure, a square structure, a triangular structure, an I-shaped structure, etc., which makes the structure flexible and the materials convenient to obtain.

[0045] The first magnetic head 11 includes at least two magnets 111, which are stacked and connected to each other along a first direction. Alternatively, in this embodiment, the first magnetic head 11 may have only one magnet 111. Using at least two magnets 111 reduces the size of a single magnet 111 while maintaining the same magnetic force, thus lowering costs. Specifically, the number of magnets 111 is not limited; the number of magnets 111 can be as follows: Figure 2 The three shown can also be two, four or more.

[0046] like Figure 2 As shown, the first magnetic head 11 also includes a housing 112, and each magnet 111 is fixed inside the housing 112. The outer wall of the housing 112 is connected to the connecting rod 12. Of course, in this embodiment, there is no limitation on the connection method between the magnets 111. For example, the magnets 111 can also be connected by binding or clamping through binding structures, clamping components, etc. After setting the housing 112 to place the magnets 111 inside the housing 112, the structure of the first magnetic head 11 is more regular, the stability of the magnets 111 is better, and it is convenient for the first magnetic head 11 to be connected to the connecting rod 12 through the housing 112.

[0047] In this embodiment, the specific structure of the outer shell 112 is not limited. For example, it can be a closed shell or a partially open structure.

[0048] In this embodiment, the connection method between the connecting rod 12 and the first magnetic head 11, and the connection method between the connecting rod 12 and the counterweight 13, are not limited. Preferably, the connecting rod 12 and the first magnetic head 11 are connected by welding, that is, the connecting rod 12 and the outer shell 112 are connected by welding, and the connecting rod 12 and the counterweight 13 are also connected by welding. This facilitates operation and ensures stable connection. Of course, the connecting rod 12 and the first magnetic head 11 can also be connected by welding, and the connecting rod 12 and the counterweight 13 can be connected by fasteners, snap-fit, or other means. Alternatively, the connecting rod 12 and the first magnetic head 11 can be connected by fasteners, snap-fit, or other means, and the connecting rod 12 and the counterweight 13 can be connected by welding.

[0049] like Figure 1 As shown, the sheet separation mechanism also includes a magnetic sheet separator 4 and a support 5. The support 5 is located on the periphery of the base 2, and the magnetic sheet separator 4 is mounted on the support 5. Specifically, it includes a drive unit 41 and a second magnetic head 42. The drive unit 41 is used to drive the second magnetic head 42 to move, so that the second magnetic head 42 moves closer to or away from the sheet 3 placed in the sheet placement area. That is, after the sheet 3 is placed in the sheet placement area, the drive unit 41 drives the second magnetic head 42 to move closer to the side of the sheet 3, so that the second magnetic head 42 is attracted to the side of the sheet 3 by magnetic attraction. The effect of the second magnetic head 42 on the sheet 3 is the same as the effect of the first magnetic head 11 on the sheet 3. By adhering to the sheet 3, the adjacent two sheets 3 repel each other to achieve the effect of sheet separation.

[0050] Specifically, the number of supports 5 corresponds to the number of magnetic sheet separators 4, and the number and placement of the magnetic sheet separators 4 can be set according to the shape and size of the actual sheet material 3. Figure 1 As shown, the magnetic sheet separator 4 is arranged in two rows. The two rows of magnetic sheet separators 4 are located on the first side 31 and the second side 32 of the sheet 3, respectively. The first side 31 and the second side 32 are two sides of the sheet 3 that are arranged opposite to each other. The handheld sheet separator 1 is located on the third side 33 of the sheet 3. After the gripping mechanism grips the sheet 3, it can move to the third side 33 to avoid interference with the magnetic sheet separators 4 located on the first side 31 and the second side 32.

[0051] Of course, in this embodiment, the fourth side 34 can also be provided with a magnetic separator 4 or a handheld separator 1. This fourth side 34 is opposite to the third side 33, and the specific configuration can be determined according to the actual situation of the sheet material 3. Figure 1As shown, when the sheet metal 3 has a trapezoidal structure, the two sides of the trapezoidal structure form a first side 31 and a second side 32, respectively, the bottom edge forms a third side 33, and the top edge forms a fourth side 34. Magnetic sheet separators 4 are respectively provided on the first side 31 and the second side 32. The third side 33 is relatively longer, and the fourth side 34 is relatively shorter. Therefore, the aforementioned handheld sheet separator 1 is provided on the third side 33, and a handheld sheet separator 1 can also be provided on the fourth side 34. The gripping mechanism can grip the sheet metal 3 and move it towards the third side 33, avoiding interference with the magnetic sheet separator 4.

[0052] like Figure 1 As shown, the first side 31 is provided with three magnetic separators 4, and the second side 32 is provided with two magnetic separators 4. The number of magnetic separators 4 can also be other than the specified number, depending on the length and other dimensions of the side of the sheet material 3. No specific limitation is made here. Alternatively, in this embodiment, the first side 31 and the second side 32 of the base 2 can each be provided with multiple magnetic separators 4, depending on the shape of the material placed in the sheet material placement area.

[0053] The sheet-splitting mechanism also includes a lifting unit (not shown in the figure). The lifting unit drives the base 2 to move relative to the support 5 in a first direction. The handheld sheet separator 1 is attracted and fixed to the sheet 3. When the lifting unit is lifting the base 2, it drives the handheld sheet separator 1 to rise and fall through the sheet 3, while the positions of the support 5 and the magnetic sheet separator 4 remain unchanged. The relative positions of the sheet 3 and the second magnetic head 42 can be adjusted by lifting the base 2 and the sheet 3, ensuring that the second magnetic head 42 can perform the sheet-splitting function. Of course, in this embodiment, the lifting unit can also drive each support 5 to move to adjust the relative position of the second magnetic head 42 and the sheet 3. Since there can be multiple supports 5, and each support 5 is spaced apart on the periphery of the base 2, the method of lifting the base 2 by setting the lifting unit can reduce the number of lifting units, simplify the overall structure, and reduce costs compared to the method of driving each support 5 by setting the lifting unit.

[0054] The base 2 also features a perforated structure. Specifically, the base 2 can be constructed as a single plate with perforated holes or grooves formed within it. Alternatively, the base 2 can be formed by fixing multiple strip plates together, with perforations between the strip plates. This perforated structure reduces the amount of material used in the base 2, lightens its overall weight, and lowers the driving force required for the lifting mechanism to raise and lower the base 2, thereby reducing costs and improving economic efficiency.
