[0033] To facilitate understanding of the present invention, the present invention is described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it may be directly attached to the other element, or one or more intervening elements may be present.

The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only. In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating relative importance or implicitly specifying the number of technical features indicated. Therefore, unless otherwise specified, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; "plurality" means two or more. The term "comprising" and any variations thereof are intended to be non-exclusive, and one or more other features, integers, steps, operations, units, components, and / or combinations thereof may be present or added.

[0034] In addition, unless otherwise expressly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. All technical and scientific terms used in this specification have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] With the increasing demand for industrial automation, the demand for automation of stamping lines is also increasing. Among them, feeding automation is an important link in the automated stamping line. How to achieve a highly automated feeding process is of great significance.

[0037] The shearing assembly is used to cut the material, and the cut material needs to be transferred to the subsequent processing station through the transfer mechanism, such as the stamping station of the stamping mechanism. At present, after the shearing assembly cuts the workpiece, the workpiece falls into the conveyor belt, and is forwarded to the loading point of the stamping mechanism by the conveyor belt. The transmission distance between the shearing assembly's drop point and the stamping mechanism's loading point is not long. The workpiece is then grabbed by the robot at the loading point and moved to the stamping mechanism for stamping. The workpiece will be offset when it is transported by the conveyor belt, so it needs to be centered after arriving at the loading point. The grabbing position of the robot is usually fixed, and each time the workpiece is transferred, it needs to be centered by an additional centering assembly or manually, which affects production efficiency.

[0038] Therefore, in order to overcome the existing technical defects, the present invention provides a transfer mechanism embodiment, which is suitable for transferring workpieces between the blanking point of the shearing assembly and the loading point of the stamping assembly. This embodiment has a centering function and the workpiece will not deflect during the movement.

[0039] like Figure 1-9 , which is a schematic diagram of an embodiment of the transfer mechanism provided by the present invention.

[0040] Please refer to Figure 1-9The transfer mechanism 1 includes a support base 11, a tray assembly 12, and a first movable assembly 13. The first movable assembly 13 is disposed on the support base 11 and is in transmission connection with the tray assembly 12, driving the tray assembly 12 to reciprocate. The tray assembly 12 is provided with a support station 121, which is surrounded by a flapping plate 14. The flapping plate 14 includes a fixed flapping plate 141 and a movable flapping plate 142. The size of the support station 121 can be adjusted by adjusting the position of the movable flapping plate 142.

[0041] This embodiment only needs to adjust the movable beating plate 142 once according to the size of the workpiece, and the subsequent blanks will fall into the specified supporting station 121. During the movement, due to the limitation of the beating plate 14 and the synchronous movement of the supporting station 121 with the workpiece, the workpiece will not be offset during the movement, and no additional centering operation is required when the workpiece arrives at the loading point, which simplifies the work process and improves production efficiency.

[0042] Or in other embodiments, after the blank falls into the supporting station 121, the movable beating plate 142 is used to move and beat the workpiece to center it.

[0043] In one embodiment, the first moving assembly 13 includes a first pushing member 131 . The telescopic rod of the first pushing member 131 is connected to the tray assembly 12 via a connecting member 132 . The connecting member 132 is in rolling contact with the surface of the support base 11 .

[0044] Specifically, the support base 11 has a horizontal plane, and the tray assembly 12 and the first movable assembly 13 are arranged on the horizontal plane. The main body of the tray assembly 12 is a rectangular support frame 122 surrounded by multiple support rods. The first pusher 131 adopts a cylinder, and the movement direction of the cylinder piston is consistent with the feeding direction. The first movable assembly 13 is located below the support frame 122 and is connected to the support base 11. The first movable assembly 13 is arranged horizontally, and its telescopic rod moves in the horizontal direction. The telescopic rod is fixedly connected to the support frame 122 through the connecting member 132, and the support frame 122 is suspended above the horizontal plane of the support base 11 and does not contact the horizontal plane of the support base 11. The tray assembly 12 is driven to move by the first movable assembly 13, and then the workpiece in the tray assembly 12 is driven to move.

[0045] Connecting member 132 contacts the horizontal surface of support base 11 via pulleys 133, which are located on either side of connecting member 132 and are fixedly connected to the connecting member 132. The horizontal surface of support base 11 is provided with pulley grooves 111 that mate with pulleys 133. The orientation of pulley grooves 111 aligns with the expansion and contraction direction of the cylinder and serves to limit the rolling direction and distance of pulley 133. Pulleys 133 support connecting member 132 while also providing rolling friction.

[0046] In one embodiment, a limit assembly 15 is included. The limit assembly 15 is disposed on the support base 11 and is located in the travel path of the telescopic rod of the first pusher 131. The limit assembly 15 includes a limit screw 151, a limit nut 152, a limit seat 153, and a limit block 154. The limit block 154 is disposed at the top of the telescopic rod of the first pusher 131. The limit screw 151 is fixedly connected to the limit block 154 and is coaxially arranged with the telescopic rod of the first pusher 131. The limit seat 153 is sleeved on the limit screw 151 and is fixedly connected to the support base 11; the limit nut 152 is sleeved on the limit screw 151, and the limit nut 152 and the limit block 154 are respectively located on both sides of the limit seat 153.

[0047] Specifically, the limiting assembly 15 is used to limit the range of movement of the first pusher 131, that is, to limit the feeding range of the tray assembly 12. The limiting nut 152 and the limiting block 154 are respectively located on both sides of the limiting seat 153, and both are larger than the aperture size of the limiting seat 153 for the limiting screw 151 to pass through. Therefore, the distance between the limiting block 154 and the limiting seat 153 is the range of movement of the first pusher 131, that is, the feeding length of the tray assembly 12. By adjusting the position of the limiting nut 152 on the limiting screw 151, the distance between the limiting block 154 and the limiting seat 153 is adjusted, thereby adjusting the feeding length of the tray assembly 12. The limiting seat 153 plays the role of supporting the limiting screw 152 and limiting the limiting block 154.

[0048] Since the gripping center of the manipulator at the loading point of some types of stamping mechanisms is fixed, workpieces of different sizes need to adjust the movement stroke of the first pusher 131 through the limit assembly 15 to match the gripping center of the manipulator.

[0049] In one embodiment, the movable slapping plate 142 is respectively arranged at the exit end and the left and right ends of the supporting station 121, and the fixed slapping plate 141 is respectively arranged at the entrance end of the supporting station 121. The movable slapping plate 142 is moved by a cylinder, a servo motor or a slide rail.

[0050] Furthermore, the movable flapping plate 142 is a T-shaped structure, with a wide upper portion serving as a flapping portion and a narrow lower portion serving as a connecting portion for connecting to a cylinder or a slide rail. Both ends of the flapping portion are bent at a predetermined angle toward the outside of the support station 121. The top of the fixed flapping plate 141 is an inclined surface 143 facing the inside of the support station 121.

[0051] Specifically, the mobile flapping plate 142 is driven by a pneumatic cylinder. The mobile flapping plate 142 cooperates with the fixed flapping plate 141 to flap and center the four sides of the workpiece. The two ends of the flapping portion of the mobile flapping plate 142 are bent at a predetermined angle toward the outside of the support station 121 to prevent the edges of the workpiece from interfering with the mobile flapping plate 142 and getting stuck during blanking. The top of the fixed flapping plate 141 is an inclined surface 143 facing the inside of the support station 121, which facilitates the workpiece to contact the fixed flapping plate 141 and slide into the support station 121, thereby preventing blanking from accumulating.

[0052] In one embodiment, a plurality of parallel supporting bars 123 are provided at the bottom of the supporting station 121 , and a plurality of rollers 124 are provided on the sides of the supporting bars 123 .

[0053] There are three support bars 123, arranged parallel to the feeding direction. One support bar 123 is located on each side of the support station 121. Each support bar 123 is equipped with a row of rollers 124, located on the side of the support bar 123 closer to the interior of the support station 121. A support bar 123 is located in the middle of the support station 121, with a row of rollers 124 on each side. The rollers 124 facilitate the movement of blanked workpieces into position within the support station 121.

[0054] In one embodiment, it includes a frame 2 and a shearing assembly 3. The shearing assembly 3 and the transfer mechanism 1 are arranged on the frame 2. The shearing assembly 3 is located at the entrance end of the transfer mechanism 1. The shearing assembly 3 includes a second pushing member 31, a shearing knife 32 and a shearing seat 33. The shearing knife 32 is arranged opposite to the shearing seat 33. The second pushing member 31 is connected to the shearing knife 32 to push the shearing knife 32 to move toward the shearing seat 33.

[0055] The frame 2 is used to support and install various parts and components. The bottom of the frame 2 is connected to the ground via a lifting screw 21, and the height of the frame 2 can be adjusted by the lifting screw 21. The second pusher 31 is specifically a cylinder. The telescopic end of the cylinder is connected to a shearing knife 32, which pushes the shearing knife 32 downward to shear the workpiece supported by the shearing seat 33. After shearing, the workpiece falls into the supporting station 121 in the transfer mechanism 1, and the transfer mechanism 1 transfers the workpiece to the station loading point (stamping station loading point). The above process is repeated to complete the shearing and transfer process of the workpiece.

[0056] In one embodiment, a coiling assembly 4 is provided on the frame 2 at the inlet end of the shearing plate assembly 3. The coiling assembly 4 includes a second movable assembly 41 and a clamping assembly 42. The clamping assembly 42 clamps the edge of the workpiece. The clamping assembly 42 includes two types: a fixed clamping assembly 43 and a mobile clamping assembly 44. The mobile clamping assembly 44 is in transmission connection with the second movable assembly 41. The second movable assembly 41 drives the mobile clamping assembly 44 to move toward the fixed clamping assembly 43. The fixed clamping assembly 43 is located between the mobile clamping assembly 44 and the shearing plate assembly 3 and is fixedly connected to the frame 2.

[0057] The coil assembly 4 is used to move the workpiece in front of the shear assembly 3, where it is sheared. An arc guide assembly 5 can also be provided at the inlet end of the coil assembly 4 to guide the workpiece. This assembly 5 comprises multiple rollers 51 arranged side by side, forming a channel with an arc-shaped cross-section. Cleaning blades 52 are positioned on either side of the channel to remove debris.

[0058] In one embodiment, the second moving assembly 41 includes a screw shaft 411, a guide rail 412, and a motor 413. The motor 413 is fixedly connected to the frame 2, and the guide rail 412 is provided on the frame 2. The output end of the motor 413 is connected to the screw shaft 411, and the screw shaft 411 and the guide rail 412 are arranged parallel to each other. The moving and pressing assembly 44 is in driving connection with the screw shaft 411 and is matingly connected to the guide rail 412.

[0059] The second moving assembly 41 uses a screw drive to drive the moving and pressing assembly 44. The motor 413 is a servo motor. The motor 413 and the screw shaft 411 are located below the moving and pressing assembly 44 and are fixedly connected to the frame 2. The direction in which the screw shaft 411 is arranged is consistent with the direction of movement of the moving and pressing assembly 44. There are two guide rails 412, one on each side of the screw shaft 411 and fixedly connected to the frame 2. The guide rails 412 extend from the outlet end of the inlet arc guide assembly 5 to the front of the inlet end of the fixed pressing assembly 43. The motor 413 drives the screw shaft 411 to rotate, causing the moving and pressing assembly 44, which is transmission-connected to the screw shaft 411, to move along the guide rails 412.

[0060] In one embodiment, the clamping assembly 42 includes a third pusher 421, a clamping block 422, and a clamping seat 423. The clamping block 422 is located above the clamping seat 423, with a gap between the clamping block 422 and the clamping seat 423. The clamping seat 423 is divided into two parts, with a predetermined width between the two parts. The third pusher 421 is connected to the clamping block 422, driving the clamping block 422 to move toward the clamping seat 423 below. The clamping seat 423 is used to support the workpiece.

[0061] The third pushing member 421 is specifically a cylinder, and the pressing seat 423 is divided into two blocks with a gap in the middle. When the pressing block 422 is pressed downward, it only presses the two sides of the pressing seat 423 carrying the workpiece, and the middle of the workpiece will not be subjected to pressure.

[0062] After the workpiece enters the mobile clamping assembly 44, the mobile clamping assembly 44 clamps both sides of the workpiece. After clamping, the second mobile assembly 41 drives the mobile clamping assembly 44 to move in the direction of the fixed clamping assembly 43, and then drives the workpiece to move toward the fixed clamping assembly 43. After the mobile clamping assembly 44 moves to the end of the interval, it releases the workpiece and returns it to its original position, and continues to clamp the workpiece and move it forward. Repeat the above steps to move the workpiece through the shearing assembly 3. The workpiece passes through the shearing assembly 3 to meet the length requirement. The fixed clamping assembly 43 clamps both sides of the workpiece. The shearing assembly 3 cuts the workpiece, and the cut workpiece falls into the tray assembly 12 in the transfer mechanism 1. The blanked workpiece is transferred to the loading point of the manipulator. The fixed clamping assembly 43 releases the workpiece, and the mobile clamping assembly 44 continues to move the workpiece forward.

[0063] Conventional roll-pulling assemblies typically use rollers to press the workpiece up and down, and the rolling of the rollers drives the workpiece forward. This method of movement causes the entire surface of the workpiece to contact the rollers. However, for some light and thin workpieces, the roller pressing and rolling method can damage the workpiece, affecting the yield rate of subsequent processing. The method used in this embodiment to press and drag the workpiece from both sides avoids this problem. In addition, the pressure-bearing surfaces are only the edges of the workpiece, which are usually trimmed during the stamping process, so the yield rate is not affected.

[0064] Furthermore, anti-collision sensors 45 are installed beside the guide rails 412. Anti-collision sensors 45 are installed at the front and rear ends of the guide rails 412 to detect collisions during the movement of the movable clamping assembly 44. Furthermore, a support rod 46 is installed between the two guide rails 412. The support rod 46 is arranged parallel to the guide rails 412 and has a row of rolling wheels 47 installed inside the support rod 46. A central gap in the clamping seat 423 allows the support rod 46 and the rolling wheels 47 to pass through. The rolling wheels 47 support the workpiece and reduce friction.

[0065] In one embodiment, the machine further includes an electrical box 6 and an oil supply assembly 7. The electrical box 6 is electrically connected to the transfer mechanism 1, the shear assembly 3, the coil assembly 4, the inlet arc guide assembly 5, and the oil supply assembly 7. The oil supply assembly 7 is located between the shear assembly 3 and the coil assembly 4 for supplying oil.

[0066] A feeding method embodiment is also provided. The method embodiment is implemented by the above-mentioned transfer mechanism embodiment and includes the following steps:

[0067] S100, alignment steps

[0068] The gripper moves the workpiece from the stamping mechanism to the transfer mechanism at the loading point. At this point, the workpiece's position and size are aligned with the gripper's gripping center. The position of the movable flapper is adjusted to match the workpiece's size. The pallet assembly's travel range is adjusted to match the workpiece's position. The size of the support station and the pallet assembly's travel range are determined to complete the centering operation.

[0069] S200, coil feeding step

[0070] The coiling assembly is used for coil feeding. After the workpiece enters the movable clamping assembly of the coiling assembly, the movable clamping assembly clamps the workpiece on both sides. After clamping, the second movable assembly drives the movable clamping assembly toward the fixed clamping assembly, which in turn drives the workpiece toward the fixed clamping assembly. When the movable clamping assembly reaches the end of the range, it releases the workpiece and returns it to its original position, and continues to clamp the workpiece and move it forward.

[0071] S300, Shearing Steps

[0072] The shearing step is implemented by the shearing assembly. The workpiece is moved through the shearing assembly in step S200. When the workpiece passes through the shearing assembly to meet the length requirement, the fixing clamping assembly clamps both sides of the workpiece, and the shearing assembly cuts the workpiece and blanks it into the transfer mechanism.

[0073] S400, blanking transfer step

[0074] The cut workpiece falls into the tray assembly in the transfer mechanism, and the tray assembly is driven by the first moving assembly to move to the loading point of the grabbing robot. The fixed clamping assembly releases the workpiece, and the moving clamping assembly continues to move the workpiece forward.

[0075] In summary, the transfer mechanism embodiment provided by the present invention adjusts the size of the supporting station by adjusting the movable flapping plate to accommodate the size of the workpiece being sheared and blanked by the shearing assembly, thereby limiting the position of the blanked workpiece. The first movable assembly drives the tray assembly where the supporting station is located to move. During the movement, the workpiece will not shift due to the limitation of the flapping plate, facilitating subsequent processing. The winding assembly uses a method of pressing and dragging the workpiece on both sides to move, with the contact surface only on the edges of the workpiece, ensuring the yield rate of subsequent processing.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above.
