[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 10, a mechanical signature device, including a signature device housing 1. The signature device housing 1 is in the shape of a shell and is internally provided with a storage device 14. One side of the storage device 14 is movably penetrated with a joystick 142. A centrifugal speed limiter 18 is meshed and connected to the storage device 14. A connecting rod 141 is arranged in the signature device housing 1, and the connecting rod 141 is provided with three connecting ends for braking connection. A speed change device 13 is arranged in the signature device housing 1, and the speed change device 13 is meshed and connected to the storage device 14. A connecting rod 131 is arranged on the speed change device 13, and a driven wheel 132 is arranged on the connecting rod 131. Three energy storage wheels 12 are arranged in the signature device housing 1, and the energy storage wheels 12 are located on one side of the speed change device 13. Grooves 121 are formed on the energy storage wheels 12, and the grooves 121 are connected to the driven wheel 132. A differential device 16 is meshed and connected to one side of the speed change device 13. The differential device 16 is controlled by planetary gears to ensure that the outputs of the gears do not affect each other. A button 11 is arranged on the signature device housing 1, and the bottom of the button 11 is correspondingly connected to the connecting rod 141.

[0028] When using the mechanical signature device, the end of the robotic arm 17 is a rotating shaft, with two gear structures placed thereon. The gear fixed on the robotic arm 17 controls rotation, and the other freely movable gear controls telescoping. At the same time, the upper part of the end shaft is connected to the component controlling lifting to lift the robotic arm 17. The robotic arm 17 can rotate, telescope, and lift. A pen is placed at the front end of the robotic arm 17, allowing the pen to move within a fan-shaped area and write or draw according to a pre-set trajectory. Since when the robotic arm 17 rotates, the gear controlling telescoping does not follow, it will cause the robotic arm 17 to extend or retract while rotating, which requires the differential device 16 to limit. The differential device 16 is controlled by planetary gears to ensure that the outputs of the two gears do not affect each other.

[0029] When the robotic arm 17 writes or draws, it needs to follow a set trajectory. There will be two speed change devices 13 to transmit the required control and energy. The speed change device 13 mainly consists of a driven wheel 132 that can move up and down and a driving wheel that inputs energy. By the rotation of the driving wheel, the up and down movement of the driven wheel 132 is realized, so that the energy on the driving wheel rotating at a constant speed is transmitted to the driven wheel 132 at different rates and finally output to the robotic arm 17.

[0030] The driven wheel 132 is fixed on a device that can move up and down. There is a small ball at the front end of the device to be stuck in the groove 121 of the storage device 14. When the storage device 14 rotates, it will drive the driven wheel 132 to move up and down through the formed groove 121. This will cause the speed of the driven wheel 132 to change between -1 and 1 and transmit the rotation to the robotic arm 17.

[0031] The storage device 14 is used to store the designed trajectory of the robotic arm 17. The three energy storage wheels 12 respectively store the lifting, telescoping, and rotation of the robotic arm 17. The storage device 14 stores energy through a spring. The storage device 14 is divided into an inner part and an outer part, and both parts can rotate. When the storage device 14 loses energy, the user can turn the joystick 142 to store energy for the storage device 14.

[0032] The inside of the storage device 14 is connected to a braking gear, which transmits force to maintain the movement of the entire device. At the same time, it will be accelerated multiple times and transmit the rotation to the centrifugal speed limiter 18 to maintain a constant rotation speed. The inside of the centrifugal speed limiter 18 rotates, and the outside is fixed. There are three springs and friction blocks connected inside. When the inside rotates at high speed, the friction blocks will provide a reverse force with the outside to slow down the rotation.

[0033] To simplify the use of the signature machine, all operations are concentrated on the button 11. Pressing the button 11 for the first time will control the extension of the robotic arm 17. At this time, a pen can be placed. Pressing it a second time will start drawing. After drawing is completed, pressing it a third time will retract the robotic arm 17. The button 11 interacts with the connecting rod 141. When the button 11 is pressed, the end of the connecting rod 141 close to the button 11 will be pushed. After the connecting rod 141 is pushed, the part stuck on the storage device 14 will separate from the storage device 14 and remain in the pushed state. At this time, the driving wheel and the driven wheel 132 of the transmission will be squeezed and pressed together, and the pin at the head of the robotic arm 17 will be loosened. The connecting rod 141 will remain in the pushed state until it snaps into the next groove 121 of the storage device 14.

[0034] Please refer to Figure 1 - Figure 10 On one side of the signature machine housing 1, a robotic arm 17 is provided through. One end of the robotic arm 17 is meshed and connected to the differential device 16. A telescoping mechanism 171 is provided inside the robotic arm 17. A signature pen 172 is movably provided at the other end of the robotic arm 17. A lifting device 15 is provided inside the signature machine housing 1. One end of the lifting device 15 is movably and limit-connected to the groove 121 on one set of energy storage wheels 12, and the other end of the lifting device 15 is connected to the robotic arm 17. The end of the robotic arm 17 is a rotating shaft, with two gear structures placed. The gear fixed on the robotic arm 17 controls the rotation, and the other freely movable gear controls the telescoping. At the same time, the upper part of the end shaft is connected to the component controlling the lifting to lift the robotic arm 17. A telescoping gear is provided inside the robotic arm 17 and is connected to another gear at the front end through a belt. The inside of the telescoping component is engraved with straight teeth to control the telescoping. The driven wheel 132 of the transmission device 13 will move up and down according to the direction of the groove 121. The lifting device 15 also completes the lifting of the robotic arm 17 through the groove 121 in the storage device 14, so that the drawn handwriting can be interrupted.

[0035] Working principle: All operations are concentrated on button 11. Pressing button 11 for the first time will control the extension of robotic arm 17. At this time, signature pen 172 can be placed. Pressing it a second time will start drawing. After the drawing is completed, pressing it a third time will retract robotic arm 17. Button 11 and connecting rod 141 interact with each other. When button 11 is pressed, the end of connecting rod 141 close to button 11 will be pushed. After connecting rod 141 is pushed, the part stuck on storage device 14 will separate from storage device 14 and remain in the pushed state. At this time, the driving wheel and driven wheel 132 of the transmission will be squeezed and pressed together. The latch at the head of robotic arm 17 will be released. Connecting rod 141 will maintain the pushed state until it snaps into the next groove 121 of storage device 14. The inside of centrifugal speed limiter 18 rotates while the outside is fixed. There are three springs and friction blocks connected inside. When the inside rotates at high speed, the friction blocks will provide a force in the opposite direction through friction with the outside to slow down the rotation. Grooves 121 are engraved on the storage wheel. Driven wheel 132 of speed change device 13 will move up and down according to the trend of grooves 121. Lifting device 15 also completes the lifting of robotic arm 17 through grooves 121 in storage device 14, so as to interrupt the drawn handwriting. Storage device 14 is used to store the designed trajectory of robotic arm 17. The three storage wheels respectively store the lifting, extension and rotation of robotic arm 17. Driven wheel 132 is fixed on a device that can move up and down. There is a small ball at the front end of the device to get stuck in groove 121 of storage device 14. The rotation of storage device 14 will drive driven wheel 132 to move up and down, which will cause the speed of driven wheel 132 to change between -1 and 1 and transmit the rotation to robotic arm 17. Robotic arm 17 can rotate, extend and lift. A pen is placed at the front end of robotic arm 17, allowing the pen to move within a fan-shaped area and write or draw according to a pre-set trajectory. The signature machine adopts a pure mechanical structure, stores energy with a spring, extends robotic arm 17 to place the pen for signature, and is easy to operate.
