[0022] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1 to 2As shown, the present invention provides a robotic arm for a gift machine, comprising a base 1, a rotating module 2, a first robotic arm 3, a second robotic arm 4, and a robotic claw 5; the rotating module 2 is mounted on the base 1.

[0025] The first robotic arm 3 includes a base 31, a first motor 32, a crank 33, a support terminal 34, and a first swing arm 35. The base 31 is fixedly mounted on the rotating module 2 and rotates around the base 1 following the rotation of the rotating module 2. Two first swing arms 35 are arranged in parallel, and their lower ends are respectively rotatably connected to the base 31, so that the first swing arms 35 can swing up and down on the base 31. The first motor 32 is mounted on the base 31, and the crank 33 is drivenly connected to the first motor 32. The support terminal 34 is fixedly connected to one of the first swing arms 35, and the support terminal 34 contacts the end of the crank 33 to form a cam mechanism.

[0026] The second robotic arm 4 is rotatably connected to the upper ends of the two first swing arms 35, forming a parallelogram linkage mechanism. The robotic gripper 5 is mounted on the second robotic arm 4.

[0027] The most distinctive feature of this device is that the first robotic arm 3 adopts a parallelogram linkage structure and is driven by a cam. During control, the first motor 32 rotates, driving the crank 33 to rotate and retract. The support terminal 34, lacking support, swings backward, causing the first robotic arm 3 to swing outward as a whole. The second robotic arm 4, connected to the first robotic arm 3, remains vertical due to the principle of the parallelogram linkage.

[0028] This design is simple in structure, abandoning the hydraulic rod drive design of real-world engineering machinery, greatly reducing the difficulty of operation and making it more suitable for recreational use. Furthermore, the structure is small in size and structurally stable and reliable. In particular, the use of a cam principle between the crank 33 and the support terminal 34 facilitates installation and maintenance. Since there is relative sliding between the end of the crank 33 and the surface of the support terminal 34, to ensure smooth sliding and reduce noise and vibration, preferably, the end of the crank 33 is rotatably connected to a roller.

[0029] Rotating module 2 can rotate left and right to control direction. Mechanical claw 5 is used to grasp objects.

[0030] This utility model also includes components such as a housing, but since these components do not affect actual operation, they will not be described in detail here.

[0031] like Figure 2 As shown, the first robotic arm 3 also includes a detection device 36, which is fixedly installed on the base 31; a trigger disk 37 for triggering the detection device 36 is fixedly installed at the lower end of the first swing arm 35, and the detection device 36 is directly opposite the trigger disk 37.

[0032] When the first swing arm 35 rotates, the trigger disk 37 will rotate accordingly. When it rotates to a specific angle, it will trigger the detection device 36 to send a detection signal, thereby assisting the control system in determining the current swing position of the first robotic arm 3.

[0033] Preferably, a torsion spring is provided between the seat 31 and the first swing arm 35, which can help maintain stability between the first swing arm 35 and the seat 31, and can also help provide a certain force to reduce the burden on the motor.

[0034] like Figure 3 As shown, specifically, the mechanical claw 5 includes a telescopic device 51, a connecting arm 52, and a claw body 53; the telescopic device 51 is fixedly installed on the second mechanical arm 4, and its telescopic end extends and retracts along the axial direction of the second mechanical arm 4; the two connecting arms 52 are arranged in a V-shape, and their upper ends are rotatably connected to the second mechanical arm 4; the two claw bodies 53 are mirror-oriented, and their inner sides are provided with action terminals 531, the middle part of the action terminals 531 is rotatably connected to the lower ends of the two connecting arms 52 respectively, and the ends of the action terminals 531 are rotatably connected to the telescopic end of the telescopic device 51 respectively.

[0035] When an object needs to be grasped, the telescopic device 51 retracts upward, causing the two claws 53 to grasp and close via the actuation terminal 531. This process utilizes the lever principle, with the connecting arm 52 acting as the fulcrum of the actuation terminal 531, coordinating with the swinging motion of the terminal 531. When the telescopic device 51 extends downward, the claws 53 are released.

[0036] like Figure 4 As shown, specifically, the rotating module 2 includes a rotating motor 21, a rotating shaft 22, and a detection component; the rotating motor 21 is fixedly installed at the bottom of the base 1, the rotating shaft 22 is connected to the rotating motor 21 in a transmission manner, and the upper end of the rotating shaft 22 is fixedly connected to the base 31; the detection component is located around the rotating shaft 22.

[0037] Furthermore, the detection component preferably includes a detection switch 23 and a trigger terminal 24; the trigger terminal 24 is fixedly mounted on the rotating shaft 22 and rotates with the rotating shaft 22; the two detection switches 23 are fixedly mounted on both sides of the base 1, located around the rotating shaft 22 and directly opposite the trigger terminal 24.

[0038] When the player operates the entire robotic arm to turn left or right, the rotary motor 21 will respond and rotate, driving the base 31 to rotate the corresponding angle via the shaft 22. The detection component receives the signal, specifically the trigger terminal 24, which, along with the rotation of the shaft 22, triggers the detection switch 23. The control system will then recognize that the rotation module 2 has rotated to its limit position, and the rotary motor 21 will stop.

[0041] This utility model provides a robotic arm and its associated game machine for gift machines.

It also features a rotating module and a mechanical gripper for rotation and grasping control, offering high playability. A buffer structure ensures durability and smooth operation.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
