[0002] The blanking robot is a special equipment in the field of industrial automation that integrates blanking technology and robotic technology. The robot can be used in the die-casting machine to realize the blanking operation of the die-casting machine. The die-casting machine uses aluminum-magnesium alloy to manufacture car horns. The blanking robot can drive the product out of the die-casting machine.

[0003] In the related technology, the unloading robot includes a support frame, a first cylinder is provided on the support frame, a second cylinder is provided on the driving shaft of the first cylinder, a mechanical claw is provided on the driving shaft of the second cylinder, the first cylinder is used to drive the second cylinder to move, and the second cylinder is used to drive the mechanical claw to move, and the first cylinder and the second cylinder are arranged perpendicular to each other.

[0004] The first cylinder drives the second cylinder into the die-casting machine. The second cylinder can drive the mechanical claw to pick up the product, and then the first cylinder drives the second cylinder out of the die-casting machine.

[0005] Since the first cylinder is set on the ground, the first cylinder needs to drive the second cylinder to extend into or out of the die-casting machine in a straight line, resulting in a larger overall volume of the first cylinder, that is, the unloading robot occupies a larger space, making it difficult for the unloading robot to adapt to some places with smaller spaces, affecting the applicability of the unloading robot. Summary of the Invention

[0006] In order to improve the problem that the blanking robot occupies a large space, the present application provides a blanking robot.

[0007] This application provides a blanking robot that adopts the following technical solution: A blanking robot includes a support frame, a moving component is provided on the support frame, a rotating component is provided on the moving component, a connecting piece is provided on the rotating component, a mechanical claw is provided on the connecting piece, the moving component is used to drive the mechanical claw close to or away from the product, and the rotating component is used to drive the connecting piece close to or away from the die-casting machine.

[0008] By adopting the above technical solution, the connecting part is driven to rotate by the rotating component, so that the connecting part can be located in the die-casting machine, and the moving component drives the connecting part to move, so that the mechanical claw can grab the product; driven by the rotating component, the unloading robot replaces linear movement by rotation, reducing the moving space of the unloading robot, so that the unloading robot can adapt to smaller space, allowing some manufacturers with smaller space to use it.

[0010] By adopting the above technical solution, the first connecting bar is rotatably connected to the second connecting bar, and the first limit bar is rotatably connected to the second limit bar, and the second limit bar is rotatably connected to the second connecting bar, so that the rotation angle between the first connecting bar and the second connecting bar can be adjusted, so that the staff can make adaptive adjustments according to the actual space, further increasing the adaptability of the manipulator.

[0011] Optionally, a first magnet is provided on the support frame, a second magnet is provided on the first limit bar, the first magnet repels the second magnet, a reset spring is provided on the first connecting bar, the reset spring is arranged on the first limit bar, and the first magnet is located on the rotation path of the first connecting bar; when the first connecting bar is located in the die-casting machine, the first magnet repels the second magnet, and the second connecting bar rotates toward the direction of the first connecting bar; when the first connecting bar is detached from the die-casting machine, the reset spring drives the first limit bar to reset.

[0012] By adopting the above technical solution, when the rotating component drives the first connecting bar to rotate toward the die-casting machine, since the first magnet is located on the rotation path of the first connecting bar, the first magnet repels the second magnet, so that the first limit bar can move in the direction of the reset spring until the first connecting bar is located in the die-casting machine, thereby achieving that the first connecting bar and the second connecting bar can gradually reduce the space occupied by rotation during the rotation process, so that the second connecting bar can be smoothly inserted into the die-casting machine; when the rotating component drives the first connecting bar to rotate toward the side away from the die-casting machine, the force of the first magnet repelling the second magnet is reduced, and the reset spring drives the first limit bar to rotate, allowing the first limit bar and the second limit bar to be reset, thereby achieving the reset of the first and second connecting bars, thereby achieving that the first and second connecting bars can gradually increase the rotation space during the rotation process, so that the mechanical claw can place the product to the specified position; by gradually changing the connecting member during the rotation, the collision between the mechanical claw and the internal structure of the die-casting machine is effectively prevented. This compact design not only achieves functional integration but also avoids increasing additional space, and is particularly suitable for the die-casting workshop's requirements for miniaturization of equipment.

[0013] Optionally, a stop bar is provided on the surface of the first limit bar close to the reset spring, and the stop bar abuts the second limit bar; when the second limit bar abuts the stop bar, the first limit bar and the second limit bar are parallel to each other.

[0014] By adopting the above technical solution, the stop bar abuts against the second limit bar, and the stop bar is located on the side of the first limit bar close to the reset spring, so that the stop bar can limit the first limit bar from continuing to rotate, so that the first limit bar and the second limit bar will not be over-reset, that is, the first limit bar and the second limit bar can be parallel to each other, reducing the situation where the reset spring produces over-reset.

[0015] Optionally, a connecting groove is provided on the second connecting bar, a connecting rod is provided in the connecting groove, a connecting hole is provided on the second limiting bar for inserting the connecting rod, and the second limiting bar is detachably connected to the first limiting bar; when the connecting rod is inserted into the connecting hole, the second limiting bar is rotatably connected to the second connecting bar.

[0016] By adopting the above technical solution, the second limit bar is detachably connected to the first limit bar, and the connecting rod is inserted into the connecting hole, so that the second limit bar can be replaced, thereby allowing the distance between the first limit bar and the second limit bar to be adjusted, that is, adjusting the angle between the first connecting bar and the second connecting bar, so that the first connecting bar and the second connecting bar can adapt to different models of die-casting machines and sites, further increasing the adaptability of the connecting parts.

[0017] Optionally, a mounting groove is provided on the second connecting bar, and the mounting groove extends to the side of the second connecting bar. The mechanical claw is provided with a mounting block for inserting into the mounting groove, and the second connecting bar is slidably connected to a fixing bar for blocking the mounting groove; when the mounting block is inserted into the mounting groove and the fixing bar blocks the mounting groove, the mechanical claw is fixed on the second connecting bar.

[0018] By adopting the above technical solution, the staff inserts the mounting block into the mounting groove, and then slides the fixing bar so that the fixing bar can block the mounting groove, so that the mounting block can be fixed in the mounting groove, that is, the mechanical claw can be fixed on the second connecting bar, thereby facilitating the replacement of the mechanical claw.

[0019] Optionally, a locking spring is provided on the second connecting bar, a locking block is provided on the locking spring, the locking block is slidably connected to the fixing bar, and the locking spring is used to drive the fixing bar to block the installation slot; when the fixing bar does not block the connecting slot, the fixing bar can block the installation slot.

[0020] By adopting the above technical solution, the staff slides the fixing bar so that the fixing bar does not block the connecting groove. Since the locking block is slidably connected to the fixing bar, the fixing bar can still block the installation groove, so that the staff can replace the second limit bar. The locking spring drives the fixing bar to block the installation groove through the locking block, reducing the movement of the fixing bar during the rotation of the connecting piece, so that the fixing bar can stably block the installation groove.

[0021] Optionally, a fixing spring piece is provided on the fixing bar for inserting into the connecting groove; when the reset spring is in a compressed state, the second limiting bar squeezes the fixing spring piece; when the fixing spring piece is located in the connecting groove, the second limiting bar abuts against the fixing spring piece, and at this time the fixing bar blocks the installation groove.

[0022] By adopting the above technical solution, when the connecting part rotates toward the die-casting machine, the first magnet repels the second magnet, causing the first limit bar to rotate toward the reset spring. The reset spring is in a compressed state. At this time, the second limit bar can squeeze the fixed spring piece, so that the fixed spring piece is fixed in the connecting groove, reducing the possibility of the fixed bar sliding on the second connecting bar; when the connecting part rotates in the direction away from the die-casting machine, the reset spring drives the first limit bar to reset. At this time, the second limit bar is reset, that is, the second limit bar only abuts against the fixed spring piece. At this time, the unloading robot is in the initial state, so that the staff can slide the fixed bar and replace the second limit bar.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The rotating component drives the connecting part to rotate, so that the connecting part can be located in the die-casting machine, and the moving component drives the connecting part to move, so that the mechanical claw can grab the product; driven by the rotating component, the unloading robot replaces linear movement by rotation, reducing the moving space of the unloading robot, so that the unloading robot can adapt to smaller space, allowing some manufacturers with smaller space to use it.

[0024] When the rotating assembly drives the first connecting bar to rotate toward the die-casting machine, since the first magnet is located on the rotation path of the first connecting bar, the first magnet repels the second magnet, so that the first limit bar can move in the direction of the reset spring until the first connecting bar is located in the die-casting machine, thereby achieving that the first connecting bar and the second connecting bar can gradually reduce the space occupied by rotation during the rotation process, so that the second connecting bar can be smoothly inserted into the die-casting machine; when the rotating assembly drives the first connecting bar to rotate toward the side away from the die-casting machine, the force of the first magnet repelling the second magnet is reduced, and the reset spring drives the first limit bar to rotate, allowing the first limit bar and the second limit bar to be reset, thereby achieving the reset of the first and second connecting bars, thereby achieving that the first and second connecting bars can gradually increase the rotation space during the rotation process, so that the mechanical claw can place the product to the specified position; by gradually changing the connecting part during the rotation, the collision between the mechanical claw and the internal structure of the die-casting machine is effectively prevented. This compact design not only realizes functional integration but also avoids increasing additional space, and is particularly suitable for the die-casting workshop's requirements for miniaturization of equipment.

[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] Example 1 This embodiment discloses a blanking robot. Figure 1 A material discharging robot includes a support frame 1, a movable assembly 2 mounted on the support frame 1, and a rotating assembly 3 mounted on the movable assembly 2. The movable assembly 2 includes a movable motor 21 and a screw. The movable motor 21 is fixedly connected to the support frame 1, and the screw is fixedly connected to the drive shaft of the movable motor 21. A polished rod is fixedly connected to the support frame 1, and a mounting plate is slidably connected to the polished rod. The mounting plate is threadedly connected to the screw. When the movable motor 21 is started, the screw rotates, driving the mounting plate to move the rotating assembly 3 along the length of the die-casting machine.

[0029] Reference Figure 1The rotating assembly 3 includes a rotating motor fixedly connected to the surface of the mounting plate. A connecting member 4 is fixedly connected to the rotating motor. The connecting member 4 includes a first connecting bar 41 and a second connecting bar 42. The first connecting bar 41 is fixedly connected to the driving shaft of the rotating motor, and the second connecting bar 42 is rotatably connected to the surface of the first connecting bar 41. An operating assembly 5 is provided on the surface of the second connecting bar 42. The rotating motor drives the operating assembly 5 through the first connecting bar 41 and the second connecting bar 42 to extend into the die-casting machine, and the operating assembly 5 is capable of gripping the product.

[0030] Reference Figure 1 , the operating component 5 is used to clamp the product. The operating component 5 includes an operating motor 53, an operating rod 51 and a mechanical claw 52. The operating motor 53 is rotatably connected to the second connecting bar 42, the operating rod 51 is fixedly connected to the drive shaft of the operating motor 53, and the mechanical claw 52 is fixedly connected to the operating rod 51. When the product is in the die-casting machine, the mechanical claw 52 needs to be rotated by the operating rod 51 so that the mechanical claw 52 can grab the product in the vertical direction. When the product moves to the top of the unloading area, the operating motor 53 drives the operating rod 51 to rotate, allowing the mechanical claw 52 to drive the product to rotate, so that the mechanical claw 52 can release the product in the horizontal direction, allowing the product to fall vertically, further increasing the accuracy of the product falling.

[0031] Reference Figure 1 The mounting plate is rotatably connected with a rotating bar, which is rotatably connected to the operating motor 53. When the rotating motor drives the first connecting bar 41 to rotate, the operating motor 53 can move along the rotation direction of the rotating bar.

[0032] The implementation principle of Example 1 is: first, the rotating motor is started, and the rotating motor enables the operating component 5 to extend into the die-casting machine, and then the moving motor 21 is started, so that the mechanical claw 52 can grab the product, and through the drive of the moving motor 21 and the rotating motor, the mechanical claw 52 is separated from the die-casting machine, and finally the operating rod 51 realizes the rotation of the product. At this time, the mechanical claw 52 releases the product to realize the unloading of the product.

[0033] Example 2 Reference Figure 2 and Figure 3 This embodiment differs from Embodiment 1 in that a first limiting bar 43 is rotatably connected to the surface of the first connecting bar 41, and a second limiting bar 44 is provided on the first limiting bar 43. A connecting groove 45 is defined on the surface of the second connecting bar 42, extending through the side of the second connecting bar 42. A connecting rod 451 is fixedly connected to the wall of the connecting groove 45, and a connecting hole is defined on the surface of the second limiting bar 44 for insertion of the connecting rod 451. When the connecting rod 451 is inserted into the connecting hole, the second limiting bar 44 is rotatably connected to the second connecting bar 42.

[0034] Reference Figure 3 A rotating rod 452 is fixedly connected to the surface of the first limiting bar 43, and a rotating hole 453 is formed on the surface of the second limiting bar 44 for inserting the rotating rod 452. When the rotating rod 452 is inserted into the rotating hole 453, the first limiting bar 43 and the second limiting bar 44 are rotatably connected to each other, that is, the first limiting bar 43 and the second limiting bar 44 are detachably connected.

[0035] Reference Figure 3 A reset bar 46 is fixedly connected to the surface of the first connecting bar 41. A reset spring 461 is fixedly connected to the surface of the reset bar 46 near the first limiting bar 43. The surface of the reset spring 461 near the reset bar 46 is fixedly connected to the first limiting bar 43. A stop bar 462 is fixedly connected to the surface of the first limiting bar 43 away from the reset spring 461. The stop bar 462 extends along the length of the first limiting bar 43, that is, the stop bar 462 abuts the second limiting bar 44. When the second limiting bar 44 abuts the stop bar 462, the first limiting bar 43 and the second limiting bar 44 are parallel to each other, and the reset spring 461 is in a non-stressed state.

[0036] Reference Figure 3 A second magnet 472 is fixedly connected to the surface of the first limiting bar 43 away from the return spring 461. A placement bar 47 is fixedly connected to the surface of the support frame 1, and a first magnet 471 is fixedly connected to the surface of the placement bar 47. The first magnet 471 repels the second magnet 472 and is located in the rotation path of the second magnet 472. When the first magnet 471 repels the second magnet 472, the first limiting bar 43 and the second limiting bar 44 rotate relative to each other. At this time, the second connecting bar 42 can rotate toward the first connecting bar 41 to reduce the space occupied by the connecting member 4.

[0037] Reference Figure 2 and Figure 3 When the operating component 5 rotates toward the die-casting machine, the first magnet 471 repels the second magnet 472, and the repulsive force of the first magnet 471 on the second magnet 472 is greater than the force of the return spring 461 on the first limiting bar 43, so that the second limiting bar 44 rotates toward the first limiting bar 43, allowing the second connecting bar 42 to rotate toward the first connecting bar 41, thereby reducing the space occupied by the connecting member 4 when rotating.

[0038] Reference Figure 2 and Figure 3When the operating component 5 rotates in a direction away from the die-casting machine, the force exerted by the return spring 461 on the first limit bar 43 can be greater than the repulsive force of the first magnet 471 on the second magnet 472, so that the second connecting bar 42 can rotate in a direction away from the first connecting bar 41, allowing the mechanical claw 52 to increase the distance between the product and the die-casting machine, so as to facilitate the collection of the product.

[0039] Reference Figure 4 The second connecting bar 42 has a mounting groove 48 formed on its surface, extending through the side of the second connecting bar 42. A mounting block 481 is fixedly connected to the surface of the operating motor 53. The mounting block 481 is elastic and can be inserted into the mounting groove 48. When the mounting block 481 is inserted into the mounting groove 48, the operating rod 51 is fixed to the second connecting bar 42, meaning that the operating rod 51 is detachably connected to the second connecting bar 42.

[0040] Reference Figure 4 A fixing groove 482 is formed on the surface of the second connecting bar 42. The fixing groove 482 extends along the length of the second connecting bar 42 and connects the mounting groove 48 with the connecting groove 45. A fixing bar 483 is slidably connected within the fixing groove 482. The fixing bar 483 can block the mounting groove 48 and the connecting groove 45 and can slide along the length of the second connecting bar 42. The fixing groove 482 extends through the surface of the second connecting bar 42, making it easy for a worker to slide the fixing bar 483.

[0041] Reference Figure 4 and Figure 5 A limiting groove 49 for inserting the fixing strip 483 is provided on the surface of the mounting block 481 . When the fixing strip 483 is inserted into the limiting groove 49 , the mounting block 481 is fixed in the mounting groove 48 .

[0042] Reference Figure 5 The second connecting bar 42 has a sliding hole 486 formed on its surface, which communicates with the fixed slot 482. A sliding bar 489 is slidably connected to the sliding hole 486. A receiving groove 488 is formed on the wall of the fixed slot 482. The receiving groove 488 communicates with the sliding hole 486, and the sliding bar 489 is able to slide within the receiving groove 488. A locking block 485 is fixedly connected to the end surface of the sliding bar 489, and a locking spring 484 is sleeved on the outer surface of the sliding bar 489. One end of the locking spring 484 abuts the locking block 485, and the other end of the locking spring 484 is fixedly connected to the receiving groove 488.

[0043] Reference Figure 4 and Figure 5The surface of the fixing bar 483 is provided with a locking groove 491 for the locking block 485 to be inserted into. When the locking block 485 is inserted into the locking groove 491, the sliding bar 489 can limit the movement of the fixing bar 483. At this time, the fixing bar 483 can be inserted into the limiting groove 49, and the locking spring 484 is in a compressed state. When the locking block 485 is released from the locking groove 491, the locking spring 484 is in a compressed state.

[0044] Reference Figure 4 and Figure 6 A fixing spring 487 is fixedly attached to the surface of the fixing bar 483 and can be inserted into the connecting slot 45. When the fixing bar 483 blocks the connecting slot 45, the ends of the fixing spring 487 respectively abut the second limiting bar 44 and the wall of the connecting slot 45. When the second limiting bar 44 rotates toward the first limiting bar 43, the second limiting bar 44 squeezes the fixing spring 487, thereby limiting the movement of the fixing bar 483 within the second limiting bar 44.

[0045] The implementation principle of Example 2 is as follows: when the connecting member 4 rotates toward the die-casting machine, the first magnet 471 repels the second magnet 472, allowing the first limit bar 43 to drive the second limit bar 44 to rotate, that is, the second connecting bar 42 rotates toward the first connecting bar 41, reducing the rotation space occupied by the connecting member 4. After the mechanical claw 52 grabs the product, the connecting member 4 rotates away from the die-casting machine, and the reset spring 461 drives the first limit bar 43 to move, allowing the second connecting bar 42 to rotate away from the first connecting bar 41, so that the connecting member 4 can be unfolded when it leaves the die-casting machine, so as to increase the distance between the product unloading position and the die-casting machine.
