Description

Technical Field

[0001] This utility model belongs to the field of mechanical stamping technology, and specifically relates to a linkage manipulator for continuous synchronous stamping. Background Technology

[0002] In stamping production, robotic arms need to complete a cyclical action of "picking up → transferring → loading → returning → picking up," and their efficiency directly affects the stamping cycle time. A typical process is as follows: the robotic arm picks up the workpiece to be stamped from the stockpile or conveyor belt; moves the workpiece above the stamping die; accurately places the workpiece and exits the die area; returns to the picking position, ready for the next cycle.

[0003] The core pain point is the severe idle time during the return stroke. In a traditional robotic arm's single round trip, the return phase does not carry any workpiece, resulting in an idle stroke rate of up to 50%, leading to wasted time and operating costs. Furthermore, the motion trajectory is redundant: using a "straight-line round trip" path requires multiple changes in direction and posture adjustments, which exacerbates mechanical wear. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a linkage manipulator for continuous synchronous stamping.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a linkage robot for continuous synchronous stamping, comprising a base, wherein the top of the base is provided with an operating rod one and an operating rod two fixedly connected to each other, and a rotating rod extending through the top of the base is rotatably connected to the inside of the base via a bearing, wherein the top of the rotating rod is fixedly connected to the operating rod one and the operating rod two respectively, wherein a Geneva plate located inside the base is fixedly sleeved on the surface of the rotating rod, wherein a disc is fitted and snapped onto one side of the Geneva plate, wherein a base plate is fixedly installed on the bottom plate of the disc, and a snapping protrusion is fixedly installed at one end of the top of the base plate, wherein a loading station, a stamping station and a unloading station are sequentially formed in a circular pattern on the outer side of the base.

[0010] Preferably, the output end of the rotary motor is fixedly sleeved with a rotating rod via a coupling, and the top of the rotating rod passes through the base plate and the disc and is rotatably connected to the inner side of the base via a bearing.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0024] refer to Figures 1-5 A linkage robot for continuous synchronous stamping includes a base 1. The top of the base 1 has two operating rods, one 201 and the other 202, fixedly connected to each other. Inside the base 1, a rotating rod 2 extends through to the top of the base 1 via bearings. The top of the rotating rod 2 is fixedly connected to both operating rod 201 and operating rod 202. A Geneva plate 3 located inside the base 1 is fixedly sleeved on the surface of the rotating rod 2. A disc 4 is fitted onto one side of the Geneva plate 3. A base plate 401 is fixedly mounted on the bottom plate 401 of the disc 4. A snap-fit ​​protrusion 402 is fixedly mounted at one end of the top of the base plate 401. The outer side of the base 1 has a circumferentially formed loading station 6, a stamping station 7, and an unloading station 8. In use, the mounting component 203 adopts a modular interface, rigidly connected to operating rod 201 and operating rod 202 respectively, compatible with various robot specifications. (See attached diagram) Figure 5 As shown, the first operating lever 201 is initially located at the loading station 6, where an external robotic arm equipped with a pneumatic gripper picks up the workpiece to be stamped; the second operating lever 202 is located at the stamping station 7, where the workpiece is precisely placed into the stamping die through the extension mechanism of the robotic arm; the rotation progression frequency is achieved through the cooperation of the Geneva plate 3 and the rotary motor 5, realizing the perfect progression of the three processing stages, avoiding idle strokes, making full use of every movement progression, improving the stamping efficiency of the workshop, and reducing the time consumption and operating costs caused by multiple round trips.

[0025] One end of each of the control levers 201 and 202 is fixedly equipped with a mounting part 203. A heat dissipation hole 101 is provided on one side of the base 1. The mounting part 203 is used to connect and install with the external robotic arm mechanism in conjunction with the control levers 201 and 202 respectively. The heat dissipation hole 101 is used to dissipate heat and provide ventilation in conjunction with the rotating motor 5.

[0026] The outer side of the Geneva plate 3 is provided with equally spaced arc-shaped grooves 301, and the outer side of the Geneva plate 3 is provided with equally spaced snap-fit ​​grooves 302. The arc-shaped grooves 301 and snap-fit ​​grooves 302 are staggered with each other, and the arc-shaped grooves 301 and snap-fit ​​grooves 302 respectively cooperate with the Geneva plate 3 to achieve progressive rotation.

[0027] The arc-shaped groove 301 is used to engage with the disc 4, and the engagement groove 302 is used to engage with the engagement protrusion 402. The arc-shaped groove 301 allows the disc 4 to engage with the Geneva plate 3 during rotation, while the Geneva plate 3 remains stationary at an angle. When the engagement protrusion 402 enters the engagement groove 302, it will move the Geneva plate 3 through engagement, and the Geneva plate 3 will move around the rotating rod 2 as the center.

[0028] The base 1 has a rotating motor 5 inside. A fixing ring 501 is fixedly sleeved on the surface of the rotating motor 5 and is fixedly connected to the inside of the base 1. The fixing ring 501 will support and fix the rotating motor 5.

[0029] The output end of the rotary motor 5 is fixedly connected to the rotating rod 2 via a coupling. The top of the rotating rod 2 passes through the base plate 401 and the disc 4 and is rotated relative to the inner side of the base 1 via a bearing. The operation of the rotary motor 5 will drive the rotating rod 2 to rotate, in which the rotating rod 2 drives the disc 4 to rotate synchronously.

[0030] The loading station 6, stamping station 7, and unloading station 8 are spaced 60° apart. The angle between the operating lever 1 201 and the operating lever 202 is 60°. The loading station 6, stamping station 7, and unloading station 8 are constructed in conjunction with external facilities so that the operating lever 1 201 and the operating lever 202 pass through the loading station 6, stamping station 7, and unloading station 8 in sequence during rotation, thus realizing the progression of the stations.

[0031] Brief description of usage: In use, the loading station 6, stamping station 7, and unloading station 8 are constructed in conjunction with external facilities. The mounting component 203 uses a modular interface, rigidly connecting to operating lever 1 201 and operating lever 202 respectively, compatible with various specifications of robotic arms. (See attached...) Figure 5As shown, the first operating lever 201 is initially located at the loading station 6, where an external robotic arm equipped with pneumatic grippers picks up the workpiece to be stamped. The second operating lever 202 is located at the stamping station 7, where the robotic arm's telescopic mechanism precisely places the workpiece into the stamping die. During this process, the operation of the rotating motor 5 drives the shaft 502, the disc 4, and the base plate 401 to rotate. As the disc 4 rotates, it achieves a fitting contact with the Geneva plate 3 through the arc-shaped groove 301, while the Geneva plate 3 remains stationary at an angle. When the engaging protrusion 402 enters the engaging groove 302, it moves the Geneva plate 3 through engagement, and the Geneva plate 3 moves around the rotating rod 2 as the center. Because there are three circumferentially distributed engaging grooves 302 and arc-shaped grooves 301, the circumferential motion of the Geneva plate 3 is divided into three segments, each segment being 60°. Under the action of this mechanical transmission, the second operating lever 202 will clamp the stamped workpiece, and as the rotating rod 2 rotates, the second operating lever 202 will move to the lower material station 8 to realize the unloading of the stamped workpiece. The first operating lever 201 will clamp the workpiece from the upper material station 6 and move towards the stamped workpiece to realize the unloading of the workpiece on the stamping table. In conjunction with the external stamping equipment, the above progressive reciprocating motion is realized, and the circumferential motion is progressively divided.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
