Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, and in particular to a manipulator for die-forming. Background Art

[0002] In the standardized process of die production, the robot arm, as an indispensable executive component of the automated production line, is responsible for grabbing the die from the feeding conveyor belt and accurately placing it on the die forming machine, and after the die forming process is completed, accurately transferring the product to the discharge conveyor belt. However, the traditional robot arm design often ignores the precise positioning and stability of the die during the transfer process, which has become a major bottleneck affecting production efficiency and product quality.

[0003] Conventional manipulators only rely on the positioning system of the robot arm when picking up and placing dies, without any additional alignment device. The accumulation of small positioning errors may cause the position of the die to shift on the die-casting machine, thus affecting the die quality.

[0004] When the mold is being grabbed and transferred by the robot, if there is no effective fixing method, it is easy to be affected by factors such as air flow and mechanical vibration, causing slight deviation or shaking. Especially in a high-speed operation environment, the stability of the mold is difficult to guarantee, increasing the risk of the mold not being able to be accurately aligned on the compression molding machine, and the possible collision or falling on the discharge conveyor belt due to position deviation, causing unnecessary losses.

[0005] Traditional robot designs are often targeted at dies of specific sizes and shapes. When dies of different specifications need to be processed on the production line, the versatility of the robot is challenged. The lack of flexible alignment and adjustment mechanisms has greatly reduced the flexibility and efficiency of the production line when facing diversified product demands.

[0006] The deviation of the die not only increases the rejection rate of the finished product, but may also cause the production line to frequently stop for manual correction, seriously affecting the production rhythm and overall efficiency. The increase in scrap caused by the positioning error of the die during the molding process, as well as the possible collision and falling on the discharge conveyor belt, not only wastes raw materials, but also may cause minor damage to the equipment, increasing production costs in the long run. The deviation or fall of the die on the high-speed production line not only affects the production quality, but also may pose a safety hazard to the operator, especially in an unmanned automated production environment, the potential safety risks cannot be ignored.

[0047] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] Reference Figure 1~Figure 4 , is an embodiment of the utility model, which proposes a manipulator for die pressing, used for transferring mold pieces, including: a manipulator body 1; a transfer frame 3 is arranged at the operating end 2 of the manipulator body 1; a transfer component 4 is arranged at one end of the transfer frame 3, and the transfer component 4 includes: two guide blocks 401 are both arranged at one end of the transfer frame 3, the guide block 401 has a guide part 402, the two guide parts 402 are inclined surfaces and are arranged opposite to each other, and the two guide parts 402 are respectively used to abut against the two side walls of the mold piece; a suction cup 403, the suction cup 403 is movably arranged relative to the guide block 401, and is located above the two guide parts 402. After the suction cup 403 moves, it approaches or moves away from the guide block 401, and the suction cup 403 is used to adsorb the mold piece.

[0049] In this embodiment, the transfer rack 3 is fixedly mounted on the operating end 2 of the manipulator body 1 to serve as the bearing base of the transfer assembly 4. One end of the transfer rack 3 has two guide blocks 401. Each guide block 401 is provided with a slope as a guide portion 402. The two guide portions 402 are arranged relative to each other. The slope can guide the mold to be correctly positioned and avoid the displacement of the mold during the transfer process. The suction cup 403 is installed above the guide block 401 and can be driven by a cylinder or a motor to move up and down. By controlling the lifting and lowering of the suction cup 403, the mold can be accurately grasped and released. When the mold needs to be adsorbed, the suction cup 403 descends to the top of the mold, contacts the surface of the mold and generates sufficient adsorption force to ensure the stability of the mold during the transfer process.

[0050] The suction cup 403 moves relative to the guide block 401, and a related track can be set on the transfer frame 3 to provide the suction cup 403 with lifting and horizontal movement. The purpose of horizontal movement is that the lengths of different diaphragms may be different, and the lengths of the dies that move through the guide part 402 and enter between the two guide blocks 401 may also be different. Therefore, in the case of consistent widths and different lengths of dies, the suction cup 403 can be adjusted to the top of the center of the die by horizontally moving the suction cup 403 to improve the stability of adsorption. The whole process has a high degree of automation, which greatly improves production efficiency and precision.

[0051] Furthermore, the suction cup 403 is arranged to be lifted relative to the die, and the transfer assembly 4 further includes: a horizontal track 404, which is arranged on the transfer frame 3 and is located above the guide block 401; a moving platform 405 is arranged to be moved on the horizontal track 404; and a lifting track 406, which is arranged to be moved on the moving platform 405. After the lifting track 406 moves, it approaches or moves away from the guide block 401, and the suction cup 403 is lifted and lowered on the lifting track 406. A first linear drive member 407 is arranged on the transfer frame 3, and is used to drive the moving platform 405 to move; a second linear drive member 408 is arranged on the moving platform 405, and is used to drive the suction cup 403 to lift and lower.

[0052] In this embodiment, the horizontal track 404 is fixed on the transfer rack 3, located above the guide block 401, and provides a track for the horizontal movement of the suction cup 403. A movable table 405 is movably provided on the horizontal track 404. The movable table 405 can slide freely on the horizontal track 404 to adjust the lateral position. A lifting track 406 is vertically installed on the movable table 405, and a suction cup 403 is movably installed on the lifting track 406. The suction cup 403 can move up and down along the lifting track 406 to capture and release the die. The first linear drive member 407 is fixed on the transfer rack 3, and its output end is connected to the movable table 405. The movable table 405 can be pushed or pulled to move on the horizontal track 404, so as to adjust the lateral position of the suction cup 403 and ensure that the suction cup 403 can accurately align with the center position of the die. The second linear drive member 408 is installed on the moving platform 405, and its output end is connected to the suction cup 403, which can drive the suction cup 403 to move up and down along the lifting track 406 to achieve the adsorption and release of the mold, greatly improving the production efficiency and product quality.

[0053] Furthermore, two guide blocks 401 are movably arranged on the transfer frame 3, and the two guide blocks 401 move closer to or farther from each other. The forward and reverse screw rods 409 have a positive thread portion 4091 and a negative thread portion 4092, and the positive thread portion 4091 and the negative thread portion 4092 are respectively threadedly connected with the two guide blocks 401. The transfer assembly 4 also includes: a first gear 410, the first gear 410 is arranged at one end of the forward and reverse screw rods 409; a second gear 411 is meshedly connected with the first gear 410; and a rotating drive member 412, the rotating drive member 412 is arranged on the horizontal track 404, and is used to drive the second gear 411 to rotate.

[0054] In this embodiment, the positive and negative screw rod 409 is used as a transmission element, one end of which is a positive threaded portion 4091, and the other end is a negative threaded portion 4092. The positive threaded portion 4091 and the negative threaded portion 4092 are respectively threadedly connected to the two guide blocks 401. When the positive and negative screw rod 409 rotates, since the threads at both ends are in opposite directions, the two guide blocks 401 can be driven to move in opposite directions, that is, when one guide block 401 moves to the left, the other guide block 401 moves to the right, and vice versa. This design can ensure the synchronization of the two guide blocks 401 during movement, and prevent the mold from being offset during the grabbing process.

[0055] The first gear 410 is installed at one end of the forward and reverse screw rod 409 and is fixedly connected to the forward and reverse screw rod 409; the second gear 411 is meshed with the first gear 410, and the second gear 411 can drive the first gear 410 to rotate through the drive of the rotating drive member 412, thereby controlling the rotation of the forward and reverse screw rod 409. The control of the rotating drive member 412 The rotating drive member 412 can be an electric motor, a pneumatic motor or a hydraulic motor, etc., and the specific selection depends on the actual work requirements and environmental conditions. Its main function is to provide a power source, control the rotation speed and direction of the forward and reverse screw rod 409, and thus indirectly control the moving distance and speed of the two guide blocks 401.

[0056] Specifically, before grabbing the mold, the two guide blocks 401 are driven to move relative to each other by the rotating drive member 412 to accommodate molds of different sizes. When the mold needs to be placed, the rotating drive member 412 is started again to control the forward and reverse screws 409 to reverse, so that the two guide blocks 401 move away from each other, release the mold, and place it stably in the target position. Through the above design, the die-casting manipulator in this embodiment can achieve precise positioning and stable operation of the mold, greatly improving production efficiency and product quality. The coordinated work of the forward and reverse screws 409, the gear set and the rotating drive member 412 ensures the accuracy and reliability of the mold during the grabbing and placement process.

[0057] Furthermore, the guide block 401 also has a placement slope 413, which is arranged on one side of the guide portion 402 and connected to the guide portion 402 in an arc-shaped transition. The two placement slopes 413 are used to carry the same mold, and the distance between the two placement slopes 413 gradually decreases from top to bottom.

[0058] In this embodiment, the placement slope 413 is located on one side of the guide part 402 and is connected to the guide part 402 through an arc transition to form a progressive convergence structure. The placement slopes 413 of the two guide blocks 401 are used together to carry the mold, and the distance between the two placement slopes 413 gradually decreases from top to bottom, similar to an inverted funnel shape. The support of the placement slope 413 is mainly used for the mold before the suction cup 403 adsorbs the mold. The mold is initially positioned and offset adjusted by the guide block 401, and initially supported and fixed by the placement slope 413, thereby improving the stability and accuracy of the suction cup 403 during the adsorption process. Secondly, it is mainly used for the mold after the suction cup 403 releases the mold. The released mold first falls on the two placement slopes 413. Further, through the drive of the rotating drive member 412, the two guide blocks 401 are relatively far apart, so that the mold gradually descends, which plays a certain buffering role, avoiding the mold from falling at a higher height after the suction cup 403 directly releases the mold, resulting in position offset, wear, etc., thereby improving the production quality.

[0059] Furthermore, the guide block 401 also has a stopper 414 , which is located on one side of the placement slope 413 and is used to abut against the side wall of the die.

[0060] In this embodiment, the stopper 414 is located on one side of the placement slope 413, and its main function is to abut against the side wall of the mold to form a physical barrier to prevent excessive movement of the mold in the lateral direction, thereby ensuring the stability and accuracy of the mold during the grasping and placement process.

[0061] Furthermore, the transfer assembly 4 has two groups, which are respectively arranged on both sides of the transfer frame 3, and the transfer frame 3 is rotatably arranged on the manipulator body 1.

[0062] In this embodiment, the transfer components 4 are designed as two groups, which are respectively arranged on both sides of the transfer frame 3. The two independent transfer components 4 can perform different operations at the same time, such as one group is grabbing the mold and the other group is placing the mold, or the two groups are performing grabbing or placing operations at the same time, which greatly improves the production efficiency of the manipulator. The independent operation of the two groups of transfer components 4 enables the manipulator to more flexibly respond to the multi-task requirements on the production line, such as quickly switching between different workstations, or processing molds of different sizes and shapes at the same time. The symmetrical layout of the two groups of transfer components 4 helps to maintain the balance of the manipulator during operation, reduce the torque caused by unilateral operation, and improve the overall stability and safety.

[0063] Furthermore, it also includes: a loading conveyor 5, through which the mold piece enters between the two guide parts 402; a die-casting machine 6, after the operating end 2 of the robot body 1 rotates, the transfer component 4 that adsorbs the mold piece to be processed is located above the die-casting machine 6, and after the operating end 2 of the robot body 1 rotates, the transfer component 4 that adsorbs the mold piece that has been pressed is located above the unloading conveyor 7.

[0064] In this embodiment, the loading conveyor 5 serves as the starting point of the production line and is responsible for delivering the mold to be processed into the operating range of the manipulator. The mold is conveyed by the loading conveyor 5 and moves to the two guide parts 402. After the two guide parts 402 adjust the angle, the mold enters between the two guide blocks 401. At this time, the two side walls of the mold are in contact with the two placement slopes 413 respectively, and one end of the moving direction abuts against the stopper 414. At this time, the operating end 2 of the manipulator body 1 rises, and the transfer assembly 4 is lifted as a whole through the transfer frame 3. The two placement slopes 413 jointly support and drive the mold to move away from the loading conveyor 5. At this time, the mold remains stable under the support of the two placement slopes 413, without other interference, and has good stability, providing a stable foundation for the suction cup 403 to adsorb. Further, the suction cup 403 descends to adsorb the mold. After the manipulator body 1 rotates, it drives the mold to enter the top of the compression molding machine 6. First, The suction cup 403 releases the die, and the die falls on the two placement slopes 413. The rotating drive member 412 drives the two guide blocks 401 to move relatively far apart, so that the die falls on the processing part of the die pressing machine 6 more gently and accurately. After the die pressing machine 6 is processed, the operating end 2 of the manipulator body 1 drops, and the rotating drive member 412 drives the two guide blocks 401 to move relatively far apart, so that the suction cup 403 is located above the die, and the two guide blocks 401 are located on the side of the die. The rotating drive member 412 drives the two guide blocks 401 to move relatively close, so that the two placement slopes 413 form support for the die and lift the die. The suction cup 403 further sucks the die and transports it to the top of the unloading conveyor 7. The release above the unloading conveyor 7 is the same as the release above the die pressing machine 6. The production efficiency and product quality of the die are significantly improved, bringing technological innovation and productivity leaps to the die pressing industry.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
