Description

Technical Field

[0001] The present invention relates to the technical field of suction cups, in particular to a countable intelligent suction cup. Background Art

[0002] A suction cup is a disc-shaped tool that utilizes atmospheric pressure. It's typically made of elastic materials like rubber and silicone. When pressed against a smooth surface, the air inside is squeezed out, creating a negative pressure space. Under the influence of external atmospheric pressure, the cup clings tightly to the surface. Its applications range from bathroom hooks and glass cleaners to industrial handling equipment, all of which utilize the cup's adsorption properties to secure or transport objects. It boasts a simple structure, ease of use, and reliable adhesion.

[0003] In the process of industrial automation, factories need to accurately monitor the operating status of their equipment. Suction cups, a common material handling tool, require data such as usage frequency and operating hours to maintain equipment and assess production efficiency. For example, in an automotive manufacturing line, the suction cups on robotic arms perform a large number of parts handling operations daily. Without a counting function, companies would be unable to accurately determine the degree of wear and the remaining service life of the suction cups, potentially leading to sudden equipment failures and disrupting 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 the atmospheric pressure difference through extrusion.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 , an embodiment of the present invention provides a countable smart suction cup, comprising a first shell 1 and a second shell 33, the first shell 1 and the second shell 33 being sealedly connected by a screw 16, and the first shell 1 and the second shell 33 forming an installation cavity; A charging port 5 is provided on one side of the first shell 1, a charging module 18 is provided inside the installation cavity, a battery 15 is provided inside the installation cavity, and a control module 17 is provided on one side of the battery 15. A technical screen is provided through one side of the first shell 1, a display panel 19 is provided inside the installation cavity, and the display panel 19 is fitted with the counting screen 8. An adsorption chamber 2 is provided at the bottom of the first shell 1 and the second shell 33, and an adsorption disk 3 is connected to the bottom end of the adsorption chamber 2. A plurality of adsorption holes 21 are provided on the bottom surface of the adsorption disk 3. A pressure sensor 20 is installed at the inner edge of the adsorption chamber 2. Function keys 6 and a count reset key 7 are sequentially installed on one side of the first shell 1; One side of the second shell 33 is fixedly connected to the extension shell 10, and a dust-proof and heat-dissipating net 12 is embedded in one side of the extension shell 10. A winding rod 13 is provided on the side of the dust-proof and heat-dissipating net 12, and 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, and a linkage component is connected to one side of the cooling fan 24.

[0028] Specifically, the first shell 1 and the second shell 33 are combined, and the opposite sides of the first shell 1 and the second shell 33 are tightly fitted, thereby ensuring the tightness of the connection between the first shell 1 and the second shell 33. After the first shell 1 and the second shell 33 are assembled and installed, a cavity is provided therein. The suction cup is provided with an electrical control component arranged inside the cavity. The charging module 18 is connected to the battery 15 through a wire. The charging module 18 is actually a charging management chip. By converting the electrical energy input by the charging port 5 into a voltage and current suitable for charging the battery 15, overvoltage or overcurrent is avoided to cause damage to the battery 15. The pressure sensor 20 is installed on the inside of the suction cup 3 for detecting the pressure change between the suction cup and the surface of the object and judging the adsorption and release status of the suction cup. The suction cup body is built with a counter and a timer, and the counter and the timer are both connected to the pressure sensor 20. Whenever the pressure sensor 20 detects a complete adsorption-release cycle, the counter increases by one to record the number of times the suction cup is used. When the pressure sensor 20 detects the adsorption state, the timing starts and when the release state is detected, the timing stops to record the duration of each adsorption. The control module Block 17 uses a low-power microcontroller, which is responsible for processing the data from the pressure sensor 20 and transmitting the data. The processed data can be transmitted to the display panel 19 and finally displayed on the counting screen 8 for intuitive viewing by the staff. The suction cup also has a built-in data transmission module, which can transmit the recorded data to an external device in real time through wireless transmission methods such as Bluetooth Wi-Fi, thereby increasing its functionality. The wireless transmission used by the suction cup is a commonly used transmission method in the prior art and is widely used in various fields. Therefore, its specific structure and system principle are not described in detail here. The extension shell 10 is connected to the interior of the installation cavity formed by the first shell 1 and the second shell 33, and the air outlet of the cooling fan 24 is directly opposite the installation position of the electrical components. When the suction cup is in operation, the electrical components inside it will generate heat. The cooling fan 24 blows air into the interior of the installation cavity, which can force the heat dissipation of the electrical hardware, thereby preventing the electrical components from heating up for a long time and causing short circuit damage. In conjunction with the dust-proof heat dissipation net 12, the ventilation effect in the installation cavity can be increased, further enhancing the heat dissipation effect in the installation cavity.

[0029] Please see the attached Figure 3 , Attachment 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 is composed of ADC, STM32, TIM1, OLED, KEY1 and KEY2; Among them, ADC represents the analog-to-digital converter, which converts the analog voltage of the pressure sensor 20 into a digital quantity, STM32 represents the microcontroller, which processes data, control logic and communication, TIM1 represents the timer and counter, which is used for event counting, OLED represents the display screen, which communicates with STM32 via SPI to display counts and animations, KEY1 represents the power button used to turn on the power, trigger the power-on animation and counting interface, and KEY2 represents the reset button used to clear the count and shut down the power, triggering the shutdown animation and screen off.

[0030] Specifically, the ADC analog-to-digital converter can convert the analog voltage output by the pressure sensor 20 into a 12-bit digital quantity, where the 12-bit digital quantity is specifically 0-4095, which is determined based on the binary working principle and quantization characteristics. The STM32 microcontroller is used for the digital quantity of the ADC and processes its data. The processed data is sent to the OLED for display through the SPI protocol, and the STM32 can manage the OLED display and response buttons. In addition, the STM32 can store and manage the data, save the count value to non-volatile storage, and realize the number protection.

[0031] Please see the attached Figure 9 , the working process of the control module 17 is: S1, ADC converts the collected pressure analog value into digital value and sends it to the STM32 chip; S2 and STM32 are connected to OLED through SPI communication; S3. When the STM32 detects that the ADC value is less than the given threshold, TIM1 counts and controls the OLED to display; S4. When STM32 detects that KEY1 is pressed, the OLED displays the power-on animation and enters the counting interface; S5. When KEY2 is pressed, STM32 controls the OLED to display the shutdown animation and turns off the screen.

[0032] Specifically, the pressure sensor 20 detects pressure information and determines the adsorption and release status of the suction cup. The ADC is used to receive the pressure information of the pressure sensor 20 and convert it into a digital quantity to the STM32 chip. The STM32 chip processes the information. When the information is less than a given threshold, the counter counts it by one, and the timer starts timing to record the adsorption time. The STM32 can also transmit the counting information to the OLED for display, so that the staff can judge the number of adsorptions. KEY1 and KEY2 are the power button and the power button respectively. The STM32 is used to receive the power on / off signal to control the power on / off status of the suction cup body.

[0033] Please see the attached Figure 9 and attached Figure 10, in S1, the ADC converts the analog voltage of the pressure sensor 20 into a digital quantity for STM32 to process. The STM32 processing formula is: = ×(2 12 -1); Among them, 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, divide the input voltage by the reference voltage to obtain the ratio of the input voltage relative to the reference voltage, with a range of 0 - 1. Multiply the normalized ratio by the maximum digital value of the ADC to obtain the output digital quantity of the ADC. The actual process is as follows: The suction cup adsorbs the workpiece and generates negative pressure inside. The pressure sensor 20 detects the pressure information and outputs the voltage . Substitute the output voltage into the above formula. If the ADC is less than the predetermined threshold, trigger the counting of TIM1. Its essential principle is: The physical pressure of the pressure sensor 20 is converted into an analog voltage, and the ADC converts the analog voltage into a digital quantity and transmits it to STM32 for processing and control.

[0035] Please refer to Appendix Figure 9 and Appendix Figure 10 . In S3, the TIM1 counting formula is: ; Among them, Threshold represents the event detection threshold, and Event represents the event flag When <Threshold, when the suction cup suction event occurs, STM32 sets Event = 1 and triggers the counting of TIM1.

[0036] Specifically, the same as above, Event is the current time flag, Threshold is the currently detected threshold. When the digital quantity output by the ADC is greater than the threshold, it means that the voltage of the pressure sensor 20 is insufficient, indicating that the suction cup does not adsorb the external object, and TIM1 does not count. On the contrary, when the digital quantity output by the ADC is less than the predetermined threshold, Event is equal to 1, and its signal can be transmitted to STM32 to control TIM1 to count it.

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

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

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

[0040] Specifically, the elastic material has good elasticity and plasticity, and can conform to the subtle undulations, grooves or irregular shapes on the surface of an object, while filling gaps, reducing air residue, forming a more sealed space, thereby enhancing adsorption force and increasing the stability of adsorption.

[0041] Please see the attached Figure 1 and attached Figure 3 The four corners of the first shell 1 and the second shell 33 are provided with mounting holes 9, and the screws 16 extend into the interior of the mounting holes 9, and the tops of the first shell 1 and the second shell 33 are fixedly connected with external connecting parts 4.

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

A light rod 26 is provided inside the extension shell 10, and the light rod 26 is passed through the movable seat 23. The interior of the extension shell 10 is fixedly installed with a hanging plate 22.

[0044] Specifically, the screw rod 25 and the movable seat 23 are connected by a threaded connection, so when the screw rod 25 rotates, the movable seat 23 can be driven to move on the screw rod 25, and when the movable seat 23 moves, the cooling fan 24 can be driven to move inside the extension shell 10. When the cooling fan 24 moves, the blowing area in the installation cavity can be increased, thereby enhancing the heat dissipation effect of the electrical components in the installation cavity, and when the movable seat 23 moves, it can slide on the outside of the light rod 26, thereby increasing the directionality and stability of the movable seat 23 when moving.

When the second worm gear 29 rotates, it can drive the screw rod 25 to rotate, thereby increasing the linkage of the entire equipment. The end of the rotating rod 36 is provided with an opening, and the plug 32 is inserted into the inside of the opening and fixed to the end of the rotating rod 36 by bolts, so that the positioning ring 11 can limit the winding rod 13. At the same time, the clamping block 14 corresponds to the clamping groove provided on the outer surface of the rotating rod 36. When the rotating rod 36 rotates, the clamping block 14 is clamped into the inside of the clamping groove, thereby ensuring the normal winding of the winding rod 13. By removing the bolts that fix the plug 32, the positioning ring 11 can be removed, so that the winding rod 13 can be removed from the rotating rod 36, so as to facilitate cleaning of the sweeping brush 31.
