Description

Technical Field

[0001] The present invention relates to the field of angle grinder control technology, and in particular to a high-safety remote-controlled angle grinder with self-powered control and a profile set device thereof. More specifically, the present invention relates to an angle grinder with a grip assist belt and a remote-controlled operating system based on RFID technology, which can realize remote control and parameter adjustment of the angle grinder, and a profile set device matched therewith. Background Art

[0002] Angle grinders, also known as angle grinders, are handheld power tools widely used in the machinery, stone, fiberglass and other industries, mainly used for grinding and cutting operations. However, operating angle grinders for a long time faces several major challenges: 1. The large reaction force generated by the high-speed rotation of the workpiece can easily cause fatigue in the operator's hand muscles, affecting work efficiency and quality.

[0003] 2. Inconvenient to operate, especially when multi-angle observation is required.

[0004] 3. The handle design of traditional power tools often fails to fully consider the operator's needs for long-term use. For example, the handles of some angle grinders are thick and difficult to hold, which can easily cause hand fatigue in operators.

[0005] To address these challenges, the industry has made some attempts to improve: 1. Grip assist device: It is necessary to develop angle grinders with grip assist devices. An ideal grip assist device should be able to assist the palm to grasp the tool and reduce the grip force. It should also have features such as convenient binding, quick disassembly and replacement, and adjustable length to adapt to different usage needs and palm sizes.

[0006] 2. Remote control operation: In order to maintain the grip-assisting effect while improving the convenience of operation, remote control devices have been developed. For example, the detachable remote control controller for grinding machine speed regulation disclosed in patent CN211992482U enables the operator to easily adjust the working parameters of the tool without changing the grip posture.

[0007] 3. Improvement of handle design: Some manufacturers try to improve the operating comfort by improving the handle design. For example, patent document CN 219787830 U proposes to place the drive control circuit board inside the head shell, so as to make the handle thinner and improve the grip comfort. This design takes ergonomics into consideration and aims to reduce hand fatigue during long-term use.

[0008] However, the existing improvement schemes still have some limitations: Remote controllers are usually only matched with a single power tool and lack versatility. This means that multiple angle grinders require multiple different remote controls, which not only increases equipment costs but also may cause confusion in use.

[0009] The design of the control components of power tools still has room for improvement in terms of wiring efficiency and safety performance. As described in application publication number CN 117979603 A, although a design of mounting the wiring part and electronic components on both sides of the circuit board is proposed, it is still limited to the structural improvement of the tool body and fails to solve broader issues such as remote control and energy efficiency.

[0010] Although some designs have improved the ergonomics of the handle, these improvements are often isolated and not organically combined with other functions (such as remote control or smart operation).

[0011] Radio frequency identification (RFID) technology provides a new idea for solving the universality problem of remote controls. RFID achieves target identification through contactless data communication between the reader and the tag. In particular, passive RFID tags have the advantages of small size, low cost, low failure rate, and long service life, making them very suitable for the matching process between remote controls and remotely controlled devices. This application has been reflected in patents such as CN101129076A and CN110310466A.

[0012] In summary, developing an angle grinder that can reduce the burden on the operator's hands, achieve convenient and universal remote control, and have efficient wiring, good safety performance and ergonomic design will be an effective solution to the existing problems.

Embodiment 2:

[0079] This embodiment proposes a system that utilizes the working vibration of the angle grinder to collect energy and realize intelligent control based on the angle grinder with a remote control device in Embodiment 1.

[0080] Reference Fig.21 , the figure shows: the angle grinder outline and the location of the spindle housing; all key components, including piezoelectric ceramics, LTC3588-1 chip, supercapacitor, TPS62736 converter, CC2640R2F Bluetooth chip and STM32L073RZ microcontroller. And the connection relationship between the components. And the path of energy flow, control signal and wireless communication signal.

[0081] The system mainly includes an energy collection unit, an energy storage unit, a wireless communication unit and a control unit, all of which are integrated on the angle grinder body.

[0082] 1. System composition: Energy harvesting unit: A vibration energy harvester made of piezoelectric ceramic material with a size of 20 mm × 20 mm × 0.5 mm, fixed on the outer wall of the spindle housing of the angle grinder.

[0083] Energy harvesting circuit: LTC3588-1 energy harvesting chip is used to convert the collected AC power into stable 3.3V DC power.

[0084] Energy storage unit: A supercapacitor with a capacity of 1F and a withstand voltage of 5.5V is used to store the collected energy.

[0085] Wireless communication unit: Adopts CC2640R2F Bluetooth low energy (BLE) chip, supports BLE 5.0 protocol, and has power consumption as low as 5.9mA (when receiving).

[0086] Control unit: Uses the STM32L073RZ ultra-low-power microcontroller with a 32MHz main frequency and 192KB flash memory.

[0087] Power Management: The TPS62736 step-up / step-down converter is used to provide a regulated 3.3V output from a 0.3V-5.5V input range.

[0088] Working principle: When the angle grinder starts working, the vibration energy is collected by the piezoelectric element and converted into electrical energy. The LTC3588-1 rectifies and boosts this energy to 3.3V, which is then stored in the supercapacitor. The TPS62736 is responsible for converting the energy in the supercapacitor into a stable 3.3V power supply to power the wireless communication unit and the control unit.

[0089] The STM32L073RZ microcontroller runs in ultra-low power mode and wakes up only when it receives a wireless command. It receives control commands from the remote control through the CC2640R2F and then performs corresponding control operations, such as adjusting the speed of the angle grinder or turning it on and off.

[0090] System Features: Self-powered: By harvesting the energy generated by the working vibration of the angle grinder, the system can be self-powered without the need for an additional power source.

[0091] Low power design: Use ultra-low power chips and intelligent power management strategies to maximize energy efficiency.

[0092] Wireless control: Remote control is achieved through BLE technology, improving operational flexibility and safety.

[0093] Compact integration: All components are integrated into the angle grinder body without affecting the original structure and usage.

[0094] Energy analysis: Assume that the vibration frequency of the angle grinder under typical working conditions is 60Hz and the amplitude is 0.5g. According to the performance parameters of the piezoelectric element, about 0.1mJ of energy can be generated per working cycle. Taking into account the losses in energy conversion and storage, the effective energy utilization rate of the system is about 70%. Therefore, under continuous working conditions, the system can collect about 4.2mJ of energy per second.

[0095] The wireless communication unit consumes 5.9mA@3.3V in receive mode, or 19.47mW. The control unit consumes about 5mW in active mode. Therefore, the total power consumption of the system is about 24.47mW. This means that the system needs to work continuously for about 5.8 seconds to collect enough energy to support 1 second of full power operation.

[0096] To optimize energy usage, the system uses an intermittent working mode. When no control operations are required, the microcontroller and wireless module enter a deep sleep mode, reducing power consumption to microwatt levels. This allows the system to accumulate energy most of the time and only wake up briefly to perform tasks when needed.

[0097] Through this design, the system can achieve energy self-sufficiency in typical usage scenarios of angle grinders while providing reliable wireless control functions. This system not only improves the intelligence level of angle grinders, but also embodies the concept of efficient energy utilization, providing new ideas for the intelligence and energy saving of industrial tools.

[0098] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined in the attached technical proposal.
