Description

Technical Field

[0001] This utility model belongs to the field of stamping robot technology, and specifically relates to an inductive stamping robot. Background Technology

[0002] In order to increase interactivity and fun, various science museums and cultural venues often set up stamp collection areas. However, the current stamp collection methods have several problems.

[0003] Traditional manual stamping requires dedicated staff. This not only increases labor costs but also leads to fatigue among staff due to the repetitive, mechanical stamping motions. As working hours increase, stamping efficiency gradually decreases, and consistent quality becomes difficult to guarantee. For example, uneven stamping pressure may result in partially clear and partially blurred stamps, severely impacting the stamping effect and reducing visitor satisfaction. Furthermore, the quality of manual service is significantly affected by staff's personal emotions and physical condition. If staff are not in good spirits that day, they may display impatience or other negative emotions during service, undoubtedly creating a poor experience for visitors and damaging the overall image of the venue.

[0004] While some existing automated stamping equipment has addressed the efficiency issues of manual stamping to some extent, its paper handling is relatively limited, and it typically lacks the ability to automatically detect whether the paper is placed correctly. This requires visitors to place the paper accurately in the designated position themselves, which can be challenging for those unfamiliar with the operation, easily leading to stamping errors, omissions, and other issues that affect the accuracy and completeness of the stamping process. Summary of the Invention

[0005] The purpose of this invention is to provide an inductive stamping robot, thereby solving the defect of existing automated stamping equipment that does not have the ability to automatically detect whether the paper is placed in the correct position.

[0014] The main control board is connected to the motor, human body sensor, voice player and paper detector respectively.

[0015] Preferably, the above technical solution further includes a plurality of indicator light strips, which are sequentially arranged on the front side of the stamping platform, and the plurality of indicator light strips are respectively connected to the main control board.

[0016] Preferably, in the above technical solution, the boom frame is fixed to the main support using screws via stainless steel connectors.

[0017] Preferably, in the above technical solution, the main support includes a sub-support and a seat, and the sub-support is fixed to the seat.

[0018] Preferably, in the above technical solution, there are two human body sensors, which are respectively located at both ends of the front side of the stamping platform.

[0019] Preferably, in the above technical solution, the paper placement slot is a transparent acrylic protective cover, the front side of the transparent acrylic protective cover is provided with a paper placement notch, and the transparent acrylic protective cover is provided with a stamping notch corresponding to the position of the stamp.

[0020] Preferably, in the above technical solution, the stamp holding and fixing assembly includes a tube clamp, a fixing screw and a fixing nut. The tube clamp is fixed to the other end of the forearm frame. The tube clamp has clamping holes at both ends. The stamp is placed in the tube clamp.

[0021] Preferably, in the above technical solution, the stamp includes a stamp body, a stamp body protective cover, a telescopic hollow guide rod, a spring, a stamp body connector, and a spring connector. The stamp body is telescopically positioned at the opening of the stamp body protective cover. The stamp body protective cover is connected to the telescopic hollow guide rod, and the stamp body protective cover has a cover hole communicating with the telescopic hollow guide rod. One end of the stamp body connector is connected to the stamp body, and the other end extends through the cover hole to the telescopic hollow guide rod. One end of the spring is connected to the other end of the stamp body connector, and the other end is fixed to the other end of the telescopic hollow guide rod via the spring connector.

[0022] Preferably, in the above technical solution, the motor is a planetary motor, and the first motor fixing component includes a first L-shaped connecting rod and a first motor connecting flange connected to the first L-shaped connecting rod.

[0024] Compared with existing technologies, this utility model has the following beneficial effects:

[0025] 1. The inductive stamping robot of this utility model has a paper placement slot with a paper detector on the stamping platform. The paper detector is located behind the position where the stamp moves to the paper placement slot. When the paper detector detects paper, it can be detected that the paper has been placed in place. After placement, the motor is activated to drive the forearm frame to move the stamp to perform the stamping action, thereby detecting whether the paper is placed in place and improving the stamping success rate.

[0026] 2. This utility model uses a human body sensor to detect when a person approaches, and a voice player to guide the stamping process, thereby increasing the humanized service and attracting people to approach.

[0027] 3. The stamp component of this utility model has an internal spring telescopic structure, consisting of a set of springs and a telescopic hollow guide rod. When the stamp component contacts the paper, the springs automatically extend and retract according to the paper's resistance, adjusting the angle of the stamp component to ensure that the stamping surface is parallel to the tabletop. This effectively avoids problems such as blurry stamps and missing corners, ensuring clear and complete stamps every time, significantly improving stamping quality and providing excellent service to visitors.

Detailed Implementation

[0034] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0037] like Figures 1-4 As shown, the inductive stamping robot in this embodiment includes: a main support, a large arm frame 1, a motor M1, a forearm frame 2, a stamp, a stamping platform 15, a paper placement slot 16, a main control board U1, and several indicator light strips H1. In this embodiment, the main control board U1 can be either a 51 microcontroller control board or an STM32 microcontroller control board, but this embodiment is not limited to these.

[0038] In this embodiment, the main support includes a sub-support and a seat, with the sub-support fixed to the seat. It is worth noting that the main body of the sub-support can be a steel frame structure, which possesses high strength and good stability, ensuring a stable shape during long-term use and preventing deformation from external forces. The exterior is covered with filling materials such as sponge and foam. The sponge has good elasticity, mimicking the soft touch of the human body, while the foam serves to fill and shape, making the overall shape closer to the human body contour. It also provides some cushioning protection, preventing injury from collisions with the steel frame structure. Furthermore, to enhance the stamping experience, the sub-support can be made into a frame similar to a human skeleton. For example, the chest section of the frame can be constructed using thicker steel beams to support internal electronic components and voice broadcast speakers; the limb frames can use steel of appropriate thickness according to actual movement requirements, ensuring strength without hindering the flexible movement of the arms and other parts.

[0039] Furthermore, to enhance the user experience, the human skeleton frame can be used with various costumes. For example, in the space museum, spacesuits can be used, and astronaut costumes can be made from highly realistic spacecraft exosuits. From the selection of materials to the handling of details, everything is designed to be realistic. Whether it is the color, texture, or special markings on the surface of the spacesuit, it is highly similar to the real spacecraft exosuit. The highly realistic spacesuit is tightly wrapped around the padding and fixed by special adhesive or sewing methods. The highly realistic spacesuit makes visitors feel as if they are in a real space scene. This immersive experience greatly stimulates visitors' interest in space knowledge, making them feel as if they are having a "close encounter" with astronauts. While getting a stamped souvenir, they can also feel the charm of space culture more deeply, greatly enhancing their sense of experience and gain.

[0040] In addition, the seat back features a hollow structure. This design is not only aesthetically pleasing but, more importantly, facilitates the fixation of the ergonomic sub-support, making the sitting posture more stable and less susceptible to external forces. The hollow structure of the seat back is designed to fit the shape of the steel frame of the human skeleton. By setting corresponding fixing holes on the backrest and the steel frame, bolts or nuts are used to firmly connect the two, ensuring the stability of the sitting posture and maintaining a correct posture even under certain external interference.

[0041] Continue to refer to Figure 1 and Figure 2One end of the boom frame 1 is fixedly connected to the main support, and the other end is connected to the first motor fixing component 3. More specifically, one end of the boom frame 1 is connected to the main support via a connector. The connector has screw holes that match the boom frame 1 and the main support, and screws are used to firmly fix the boom frame 1 to the main support. The boom frame 1 is made of seamless stainless steel tubing. Stainless steel has good strength and corrosion resistance, and can withstand the stress generated during frequent arm movements, extending the service life of the equipment. A high-precision threaded connection method forms a flexible and stable arm structure. It also facilitates disassembly operations when maintenance or component replacement is required.

[0042] Motor M1 is fixed to the first motor fixing component 3. One end of the forearm frame 2 is connected to the drive unit of motor M1 through the second motor fixing component 4. The main control board U1 is connected to the motor. In this embodiment, motor M1 is a planetary motor. Planetary motors have advantages such as small size, light weight, high transmission efficiency, and high control precision. They can accurately simulate the flexion and extension movements of an astronaut's elbow to complete the key operation of stamping, presenting a good demonstration of the stamping action to visitors. The first motor fixing component 3 includes a first L-shaped connecting rod and a first motor connecting flange connected to the first L-shaped connecting rod. The first L-shaped connecting rod is connected to the other end of the upper arm frame 1, and the first motor connecting flange is connected to the end of the planetary motor. The second motor fixing component 4 includes a second L-shaped connecting rod and a second motor connecting flange connected to the second L-shaped connecting rod. The second L-shaped connecting rod is connected to one end of the forearm frame 2, and the second motor connecting flange is connected to the drive end of the planetary motor. When motor M1 receives a control signal from the main control board U1, the output shaft of the planetary motor's drive end rotates, causing the elbow joint to rotate, thus realizing the flexion and extension of the arm and simulating the astronaut's stamping action.

[0043] The stamp is fixed to the other end of the forearm frame 2 by a stamp-holding and fixing assembly. In this embodiment, the stamp-holding and fixing assembly includes a tube clamp 5, a fixing screw 6, and a fixing nut 7. The tube clamp 5 is fixed to the other end of the forearm frame 2, and clamping holes are opened at both ends of the tube clamp 5. The stamp is placed in the tube clamp, and the fixing screw 8 of the fixing screw 6 passes through the clamping hole and is threadedly connected to the fixing nut 7 to fix the stamp. The tube clamp 5 can enhance the stability of the stamping action, reduce the shaking that may occur during the stamping process, and ensure that each stamping achieves a high-quality effect.

[0044] Furthermore, the seal includes a seal body 10, a seal body protective cover 9, a telescopic hollow guide rod 11, a spring 12, a seal body connector 13, and a spring connector 14. In this embodiment, the telescopic hollow guide rod 11 preferably adopts a telescopic structure with a certain telescopic distance, such as... Figure 3The diagram shows a telescopic hollow guide rod. The stamp body 10 is telescopically positioned at the opening of the stamp body protective cover 9, with the stamping surface of the stamp body 10 slightly protruding from the opening of the protective cover 9. The stamp body protective cover 9 is connected to the telescopic hollow guide rod 11, and the protective cover 9 has a cover hole communicating with the telescopic hollow guide rod 11. One end of the stamp body connector 13 is connected to the stamp body 10, and the other end extends through the cover hole to the telescopic hollow guide rod 11. One end of the spring 12 is connected to the other end of the stamp body connector 13, and the other end is fixed to the other end of the telescopic hollow guide rod 11 via a spring connector 14. The stamp body connector 13 is preferably a screw and a matching nut. The nut abuts against the inside of the cover hole and is connected to one end of the spring 12, while the screw is connected to the stamp body 10. The spring connector 14 is preferably a screw and a nut. The screw extends from the outside of the telescopic hollow guide rod 11 to its inside, and the nut is threadedly connected to the screw for fixation. The nut is also connected to the other end of the spring 12. When the stamp component contacts the paper, the spring automatically extends and retracts according to the paper's resistance. The stamping component employs a spring-loaded telescopic structure, which automatically adjusts the angle of the stamping component based on the paper's placement and the flatness of the tabletop, ensuring the stamping surface is as parallel to the tabletop as possible. This ensures clear stamping regardless of whether the paper is perfectly flat, effectively preventing problems such as blurred or partially missing stamp images caused by the stamping surface not being parallel to the tabletop.

[0045] The stamping platform 15 is equipped with a human body sensor S1, a voice player BY, and several indicator light strips H1. The indicator light strips H1 are sequentially arranged on the front side of the stamping platform 15. Preferably, there are two human body sensors S1, located at opposite ends of the bottom front side of the stamping platform 15. Preferably, there are three indicator light strips H1, each a yellow, red, and blue color. The human body sensor model can be ZSS-S01-PIR, but this embodiment is not limited to this. The two human body sensors S1, the voice player BY, and the three indicator light strips H1 are connected to the main control board U1, and a voice broadcast speaker is installed. Combined with the two human body sensors and the three rings of indicator light strips installed at the bottom of the stamping platform 15, rich interactive functions are achieved. The detection range of the two human body sensors is set as follows: the left human body sensor detects a distance of approximately 8 meters to the left and 3 meters to the right of the stamping platform; the right human body sensor detects a distance of 3 meters to the left and 8 meters to the right (the detection range of the human body sensors is existing technology and will not be elaborated here). When a human body sensor detects someone approaching within 8 meters, it sends a signal to the main control board, which in turn sends a signal to the light strip, illuminating the front yellow indicator light strip and playing a welcome voice message. This setup attracts the attention of visitors from a distance, guiding them closer. When both human body sensors detect someone, indicating they are within 3 meters, both sensors send signals to the main control board, which in turn sends signals to the light strip, illuminating all indicator lights and playing corresponding voice messages, further creating a warm welcome atmosphere and making visitors feel specially cared for. When no one is detected within the detection range, all lights are turned off to save energy.

[0046] A paper placement slot 16 is disposed on the stamping platform 15. The paper placement slot 16 is equipped with a paper detector S2, which is located behind the position where the stamp moves to the paper placement slot 16. In this embodiment, the paper placement slot 16 is preferably a transparent acrylic protective cover. A paper placement notch is provided on the front side of the transparent acrylic protective cover, and a stamping notch is provided corresponding to a certain position of the stamp. The paper detector is located at the bottom of the stamping notch and behind the position of the stamp. The paper detector S2 is connected to the main control board. The transparent acrylic protective cover protects the stamp components from interference and damage from the external environment without affecting the visitor's observation of the stamping process. The paper detector S2 uses photoelectric sensing or capacitive sensing principles to quickly and accurately detect the placement of paper. The paper detector S2 can be an E2K series capacitive sensor or a JV300 paper measuring sensor, but this embodiment is not limited to these. When paper is placed inside the protective cover, the paper detector S2 is triggered, transmitting a signal to the main control board U1. Upon receiving the signal, the main control board U1 immediately initiates the relevant program of the arm-based stamping system, controlling the planetary motor to drive the forearm frame 2 to complete the flexion and extension movements, thus performing the stamping operation. As long as the paper is placed in the designated position, the device can automatically respond, improving the efficiency and convenience of stamping. After stamping is completed, the main control board also triggers the voice player to announce the process, reminding visitors to take the stamped document, demonstrating thoughtful service details. When the human body sensor does not detect any human signal within its detection range for a period of time, the main control board controls the indicator light strip to turn off, achieving energy saving.
