Description

Technical Field

[0001] This invention relates to the field of suction cup technology, specifically to a countable intelligent suction cup. Background Technology

[0002] A suction cup is a tool that works using atmospheric pressure. It is typically made of elastic materials such as rubber or silicone and is usually disc-shaped. When pressed against a smooth surface, the internal air is forced out, creating a negative pressure space. Under the influence of external atmospheric pressure, it adheres tightly to the surface of the object. Its applications are wide-ranging, including bathroom hooks, glass cleaners, and handling equipment in industrial production. These applications utilize the suction cup's adsorption properties to achieve fixing or moving functions, and it features simple structure, ease of use, and reliable adsorption force.

[0003] In the process of industrial automation, factories need to accurately monitor the operating status of equipment. As a common material handling tool, the frequency of use and working time of suction cups are crucial for equipment maintenance and production efficiency assessment. Taking an automobile manufacturing production line as an example, the suction cups on the robotic arm perform a large number of parts handling operations every day. If there is no counting function, the company cannot accurately judge the wear and tear and remaining service life of the suction cups, which may lead to sudden equipment failure and affect the normal operation of the entire production line.

[0004] Traditional suction cups are widely used in industry, scientific research and daily life. Their working principle is mainly based on atmospheric pressure difference, which is achieved by squeezing.

[0005] The suction cup expels internal air and uses external atmospheric pressure to firmly press it onto the surface of an object, enabling functions such as suspension and handling. However, existing suction cups generally suffer from the drawback of being single-function, only capable of adsorption, and are insufficient to meet the needs of modern production and scientific research for data monitoring and recording. Summary of the Invention

[0018] Working principle: When in use, the suction cup body can be connected to the external connector through the external connector. The suction cup contacts the object to be suctioned and presses down, generating negative pressure inside the suction chamber, and external parts can be suctioned through the suction holes. Furthermore, during adsorption, the pressure sensor can detect the pressure change between the suction cup and the object surface, determine the adsorption and release of the suction cup, and when the pressure sensor detects pressure information, its voltage parameter changes. The analog-to-digital converter detects the voltage information, converts it into a digital quantity, and transmits it to the microcontroller. The microcontroller compares the current digital quantity with a threshold digital quantity. When it is less than the threshold, it can control the timer to count and control the counter to increment by one, so that the count can be recorded. The recorded number is displayed on the counting screen for the operator to judge. When the suction cup body is used for a long time, the motor and cooling fan can be turned on. The cooling fan blows air in the direction of the electrical components to enhance the heat dissipation effect in the mounting cavity. The motor drives the double-stage worm gear to rotate, which in turn drives the first worm wheel and the second worm wheel to rotate. The second worm wheel drives the lead screw to rotate, which in turn drives the moving seat to move.

The winding rod drives the cleaning brush to move along the surface of the dustproof heat dissipation mesh to sweep away the dust attached to its surface.

[0019] This invention provides a countable smart suction cup. It has the following beneficial effects: 1. This invention uses a pressure sensor to capture the adsorption and release actions of the suction cup in real time and accurately. Combined with a high-performance counter, the counting error can be controlled within a very small range. Compared with the traditional manual recording method, it increases the accuracy during use. In addition to recording the number of uses, it can also use a timer to accurately record the duration of each adsorption.

[0020] 2. Based on the suction cup counting function, this invention can automatically generate equipment operation data, helping enterprises to understand the frequency of equipment use, working hours and other information in a timely manner. Based on this data, enterprises can reasonably arrange equipment maintenance plans, prevent failures in advance, reduce equipment downtime, thereby improving production efficiency and reducing production costs.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 The present invention provides a countable smart suction cup, including a first outer shell 1 and a second outer shell 33, the first outer shell 1 and the second outer shell 33 are sealed together by a screw 16, and the first outer shell 1 and the second outer shell 33 form a mounting cavity; A charging port 5 is provided on one side of the first outer shell 1. A charging module 18 is provided inside the mounting cavity. A battery 15 is provided inside the mounting cavity. A control module 17 is provided on one side of the battery 15. A technical screen is provided through one side of the first outer shell 1. A display panel 19 is provided inside the mounting cavity, and the display panel 19 is attached to the counting screen 8. An adsorption cavity 2 is provided at the bottom of the first outer shell 1 and the second outer shell 33. An adsorption plate 3 is connected to the bottom end of the adsorption cavity 2. Multiple adsorption holes 21 are provided on the bottom surface of the adsorption plate 3. A pressure sensor 20 is installed at the inner edge of the adsorption cavity 2. A function key 6 and a count reset key 7 are installed in sequence on one side of the first outer shell 1. An extension shell 10 is fixedly connected to one side of the second outer shell 33. A dustproof heat dissipation mesh 12 is embedded in one side of the extension shell 10. A winding rod 13 is provided on the side of the dustproof heat dissipation mesh 12. A cleaning brush 31 is installed on one side of the winding rod 13. A cooling fan 24 is installed inside the extension shell 10. A linkage component is connected to one side of the cooling fan 24.

[0028] Specifically, the first outer shell 1 and the second outer shell 33 are combined, with their opposite sides tightly fitted to ensure a tight connection. After assembly, the first outer shell 1 and the second outer shell 33 have an internal cavity. The suction cup has electrical control components housed within this cavity. The charging module 18 is connected to the battery 15 via wires. The charging module 18 is essentially a charging management chip that converts the electrical energy input from the charging port 5 into voltage and current suitable for charging the battery 15, preventing damage to the battery 15 due to overvoltage or overcurrent. A pressure sensor 20 is installed inside the suction cup 3 to detect pressure changes between the suction cup and the object surface, determining the suction cup's adsorption and release states. The suction cup body has a built-in counter and timer, both connected to the pressure sensor 20. Each time the pressure sensor 20 detects a complete adsorption-release cycle, the counter increments by one, recording the number of times the suction cup has been used. Timing starts when the pressure sensor 20 detects adsorption and stops when it detects release, recording the duration of each adsorption cycle. Block 17 uses a low-power microcontroller to process and transmit the data from the pressure sensor 20. The processed data is then transmitted to the display panel 19 and finally displayed on the counting screen 8 for easy viewing by staff. The suction cup also has a built-in data transmission module that can transmit recorded data to external devices in real time via wireless transmission methods such as Bluetooth and Wi-Fi, increasing its functionality. The wireless transmission method used by this suction cup is a commonly used transmission method in existing technologies and is widely used in various fields. Therefore, its specific structure and system principle will not be described in detail here. The extension shell 10 is connected to the mounting cavity formed by the first shell 1 and the second shell 33. The air outlet of the cooling fan 24 is directly facing the mounting position of the electrical components. When the suction cup is running, the internal electrical components will generate heat. By blowing air into the mounting cavity through the cooling fan 24, the electrical hardware can be forcibly cooled, thus preventing the electrical components from overheating during long-term operation and causing short circuit damage. Combined with the dustproof heat dissipation mesh 12, the ventilation effect in the mounting cavity can be increased, further enhancing the heat dissipation effect in the mounting cavity.

[0029] Please see the appendix Figure 3 Appendix Figure 9 and attached Figure 10 The control module 17 includes a software program module and a hardware control module 17; The hardware control module 17 consists of ADC, STM32, TIM1, OLED, KEY1 and KEY2; Among them, ADC stands for Analog-to-Digital Converter, which converts the analog voltage of pressure sensor 20 into a digital quantity; STM32 stands for Microcontroller, which processes data, controls logic, and communicates; TIM1 stands for Timer and Counter, used for event counting; OLED stands for Display, which communicates with STM32 via SPI to display the count and animation; KEY1 stands for Power Button, used to power on the device and trigger the power-on animation and counting interface; KEY2 stands for Reset Button, used to reset the count and power off the device, triggering the power-off animation and screen-off.

[0030] Specifically, the ADC (Analog-to-Digital Converter) converts the analog voltage output from the pressure sensor 20 into a 12-bit digital value, specifically 0-4095, which is determined by the binary working principle and quantization characteristics. The STM32 microcontroller is used to process the digital value of the ADC. The processed data is then sent to the OLED for display via the SPI protocol. The STM32 can also manage the OLED display and respond to buttons, and it can store and manage the data, saving the count value to non-volatile memory to achieve count protection.

[0031] Please see the appendix Figure 9 The workflow of control module 17 is as follows: S1, ADC converts the collected analog pressure signal into a digital signal and sends it to the STM32 chip; S2 and STM32 communicate with the OLED via SPI. S3. When the STM32 detects that the ADC value is less than a given threshold, TIM1 counts the number of times and controls the OLED to display the value. S4. When the STM32 detects that KEY1 is pressed, the OLED displays a power-on animation and enters the counting interface; S5. When KEY2 is pressed, the STM32 controls the OLED to display a shutdown animation and then turns off the screen.

[0032] Specifically, pressure sensor 20 detects pressure information to determine the adsorption and release state of the suction cup. ADC receives the pressure information from pressure sensor 20 and converts it into a digital value for the STM32 chip. The STM32 chip processes the information; when the information is less than a given threshold, the counter increments by one, and the timer starts counting to record the adsorption time. The STM32 can also transmit the count information to an OLED for display, allowing staff to determine the number of adsorption cycles. KEY1 and KEY2 are the power button and power button, respectively. The STM32 receives power-on / off signals to control the power-off state of the suction cup body.

[0033] Please see the appendix Figure 9 and attached Figure 10In step S1, the ADC converts the analog voltage of the pressure sensor 20 into a digital quantity for processing by the STM32, and the processing formula of STM32 is: = ×(2 12 -1); wherein, represents the input voltage, represents the ADC reference voltage, 2 12 -1 represents the maximum digital value of the ADC, represents the digital quantity output by the ADC.

[0034] Specifically, the input voltage is divided by the reference voltage to obtain the proportion of the input voltage relative to the reference voltage, with a range of 0-1. Multiplying the normalized proportion by the maximum digital value of the ADC can obtain the output digital quantity of the ADC. The actual process is as follows: negative pressure is generated inside the suction cup when it adsorbs a workpiece, the pressure sensor 20 detects pressure information and outputs voltage , substitute the output voltage into the above formula. If the ADC is less than the predetermined threshold, counting of TIM1 is triggered. The essential principle is: physical pressure is converted into analog voltage by the pressure sensor 20, the ADC converts the analog voltage into a digital quantity, and transmits the digital quantity to STM32 for processing and control.

[0035] Please refer to the appendi Figure 9 and appendi Figure 10 , in step S3, the counting formula of TIM1 is: ; wherein, Threshold represents the event detection threshold, and Event represents the event flag <Threshold, when a suction cup suction event occurs, STM32 sets Event=1 and triggers TIM1 counting.

[0036] Specifically, same as the above, Event is the current event flag, Threshold is the current detection threshold. When the digital quantity output by the ADC is greater than the threshold, it indicates that the voltage of the pressure sensor 20 is insufficient, which means that the suction cup does not adsorb an external object, and TIM1 does not count. Conversely, when the digital quantity output by the ADC is less than the predetermined threshold, Event is equal to 1, and the signal can be transmitted to STM32, which controls TIM1 to perform counting.

[0037] Please refer to the appendi Figure 9 and appendi Figure 10 , in step S3, the display formula of OLED is: = +Event in, Indicates the current count value. This represents the updated count value.

[0038] Specifically, as mentioned above, Event represents the current event flag. The updated count value can be obtained by adding the current time flag to the current count value.

[0039] Please see the appendix Figure 1 The adsorption chamber 2 and the adsorption disk 3 are made of elastic material.

[0040] Specifically, elastic materials have good elasticity and plasticity, which can conform to the slight undulations, grooves or irregular shapes of the object's surface, while filling gaps, reducing air residue, forming a more sealed space, thereby enhancing the adsorption force and increasing the stability of the adsorption.

[0041] Please see the appendix Figure 1 and attached Figure 3 Mounting holes 9 are provided at the four corners of the first outer shell 1 and the second outer shell 33, and the screw 16 extends into the interior of the mounting holes 9. External connectors 4 are fixedly connected to the top of the first outer shell 1 and the second outer shell 33.

[0042] Specifically, the inner wall of the mounting hole 9 is provided with threads corresponding to the screw 16. By screwing the screw 16 into the interior of the mounting hole 9 in sequence, the first outer shell 1 and the second outer shell 33 can be connected. When the screw 16 is tightened, the first outer shell 1 and the second outer shell 33 can be tightly connected to increase the sealing and stability of the connection between the first outer shell 1 and the second outer shell 33. Through the external connector 4, the suction cup body can be connected to external equipment for easy use.

[0043] Please see the appendix Figure 6 Appendix Figure 7 and attached Figure 8The linkage assembly includes a lead screw 25, a movable seat 23, a second worm gear 29, a first worm gear 28, a double-segment worm 30, a connecting worm 27, a third worm gear 34, and a rotating rod 36. The movable seat 23 is fixedly installed on one side of the cooling fan 24. The lead screw 25 passes through the movable seat 23. The second worm gear 29 is fixedly installed at one end of the lead screw 25. The rotating rod 36 is inserted into the inner side of the winding rod 13. The third worm gear 34 is fixedly installed at one end of the rotating rod 36. The connecting worm 27 is located on the top of the third worm gear 34, and the connecting worm 27 is meshed with the third worm gear 34. The worm gear 28 is fixedly installed at one end of the connecting worm 27. The double-section worm 30 is set on the top of the first worm gear 28 and the second worm gear 29. The extension shell 10 is equipped with a motor 37, and the output end of the motor 37 is connected to the double-section worm 30. A through slot 35 is opened on one side of the winding rod 13. A snap block 14 is installed inside the slot 35. The end of the rotating rod 36 is fixedly installed with a positioning ring 11 by bolts. The extension shell 10 is equipped with a smooth rod 26, and the smooth rod 26 passes through the moving seat 23. A hanging plate 22 is fixedly installed inside the extension shell 10.

[0044] Specifically, the lead screw 25 and the movable seat 23 are connected by a thread. Therefore, when the lead screw 25 rotates, it can drive the movable seat 23 to move on the lead screw 25. When the movable seat 23 moves, it can drive the cooling fan 24 to move inside the extension shell 10. When the cooling fan 24 moves, it can increase the airflow area inside the mounting cavity, thereby enhancing the heat dissipation effect on the electrical components inside the mounting cavity. When the movable seat 23 moves, it can slide on the outside of the smooth rod 26, thereby increasing the directional and stability of the movable seat 23 during movement. Through the rotation of the double-stage worm gear 30, the first worm wheel 28 and the second worm wheel 29 can be driven to rotate simultaneously. The first worm wheel 28 can drive the connecting worm gear 27 to rotate, the connecting worm gear 27 can drive the third worm wheel 34 to rotate, the third worm wheel 34 can drive the rotating rod 36 to rotate, the rotating rod 36 can drive the winding rod 13 to rotate, and the winding rod 13 drives the clear rod 26 to rotate. The brush 31 rotates around the connection point with the rotating rod 36, simultaneously sweeping the dustproof heat dissipation mesh 12 to prevent dust from adhering to its surface and affecting its heat dissipation performance. When the second worm gear 29 rotates, it can drive the lead screw 25 to rotate, thereby increasing the overall linkage of the equipment. The end of the rotating rod 36 has an opening, and the plug 32 is inserted into the opening and fixed to the end of the rotating rod 36 with bolts. This allows the positioning ring 11 to limit the winding rod 13. At the same time, the snap-fit ​​block 14 corresponds to the snap-fit ​​groove opened on the outer surface of the rotating rod 36. When the rotating rod 36 rotates, the snap-fit ​​block 14 snaps into the snap-fit ​​groove, thereby ensuring the normal rotation of the winding rod 13. By removing the bolts fixing the plug 32, the positioning ring 11 can be removed, thereby removing the winding rod 13 from the rotating rod 36 to facilitate cleaning of the brush 31.

[0045] In this embodiment, a countable smart suction cup can be used by connecting the suction cup body to the external connector 4. The suction cup 3 contacts the object to be suctioned and presses down, generating negative pressure inside the suction chamber 2. External components can be suctioned through the suction hole 21. Furthermore, during adsorption, the pressure sensor 20 can detect the pressure change between the suction cup and the object surface, determine the adsorption and release of the suction cup, and when the pressure sensor 20 detects pressure information, its voltage parameter changes. The analog-to-digital converter detects the voltage information, converts it into a digital quantity, and transmits it to the microcontroller. The microcontroller compares the current digital quantity with the threshold digital quantity. When it is less than the threshold, it can control the timer to count and control the counter to increment by one, so that the count can be recorded. The recorded number is displayed on the counting screen 8 for the operator to judge. When the suction cup body is used for a long time, the motor 37 and the cooling fan 24 can be turned on. The cooling fan 24 blows air in the direction of the electrical components to enhance the heat dissipation effect in the mounting cavity. The motor 37 drives the double-segment worm gear 30 to rotate, which drives the first worm wheel 28 and the second worm wheel 29 to rotate. The second worm wheel 29 drives the lead screw 25 to rotate, which drives the moving seat 23 to move. The moving seat 23 drives the cooling fan 24 to move, thereby increasing the heat dissipation area of ​​the mounting cavity. The first worm wheel 28 drives the connecting worm gear 27 to rotate, which drives the third worm wheel 34 to rotate. The third worm wheel 34 drives the rotating rod 36 to rotate, which drives the winding rod 13 to rotate. The winding rod 13 drives the cleaning brush 31 to move around the surface of the dustproof heat dissipation mesh 12 to sweep away the dust attached to its surface.

The workflow of the control module (17) is as follows: S1, ADC converts the collected analog pressure signal into a digital signal and sends it to the STM32 chip; S2 and STM32 communicate with the OLED via SPI. S3. When the STM32 detects that the ADC value is less than a given threshold, TIM1 counts the number of times and controls the OLED to display the value. S4. When the STM32 detects that KEY1 is pressed, the OLED displays a power-on animation and enters the counting interface; S5. When KEY2 is pressed, the STM32 controls the OLED display to show a shutdown animation and then turns off the screen. During adsorption, a pressure sensor detects the pressure change between the suction cup and the object surface to determine the adsorption and release of the suction cup; The suction cup body has a built-in counter and timer, both of which are connected to a pressure sensor. Each time the pressure sensor detects a complete adsorption-release cycle, the counter increments by one, recording the number of times the suction cup has been used. The timer starts when the pressure sensor detects the adsorption state and stops when the adsorption state is detected, recording the duration of each adsorption cycle.
