Description

Technical Field

[0001] This application relates to a valve body production device, in particular to an automatic assembly and detection line for valve bodies. Background Art

[0002] Valves are widely used in modern production and life. Among them, the pressure relief valve is an important safety device. The function of the pressure relief valve is to automatically open the valve when the pressure in the system exceeds the set value, release the excessive pressure, and ensure the safe operation of the system. The purpose of the pressure relief valve is to protect the safety of equipment and personnel and prevent accidents and equipment damage caused by excessive pressure. In various hydraulic, pneumatic and water supply systems, the pressure relief valve is a crucial safety component and plays a key protective role.

[0003] The T-valve is a type of pressure relief valve. The production of T-valve products mainly relies on manual assembly, which is widely used in modern manufacturing, especially in the valve production process. The T-valve is a complex component, and its core part consists of a paper core formed by stacking multiple layers of paper strips, a base with a plunger, and a housing with a spring.

[0004] However, the existing technologies of T-valves have some obvious disadvantages in practical applications. First of all, in the existing technologies, each component needs to be strictly detected before assembly, including the detection of multiple items such as component size, surface roughness, and flatness. In addition, corresponding tests also need to be carried out during the assembly process to ensure that each step meets the requirements before proceeding to the next assembly step. This multi-item detection and complex detection process not only increase the production time but also raise the production cost.

[0005] Secondly, in order to ensure the output, the existing technologies require a large amount of manual participation in production. Due to the large variety of detections, it is easy to have the situations of missed detection and wrong detection, making it difficult to control the product yield rate. This not only increases the human resource cost but also affects the quality stability of the products. The errors in manual operations are inevitable. The stability and accuracy of manual detection are relatively low, and it is easily affected by the experience and skill level of the operators, resulting in unstable detection results and affecting the quality control of the products.

[0006] In addition, the existing manual operation methods cannot effectively trace the detection data of each product. During the production process, if quality problems occur, it is difficult to quickly locate and solve the root causes of the problems, affecting the production efficiency and product reliability. Due to the lack of an effective data management and traceability system, the detection data of each product cannot be recorded and traced, which leads to the difficulty in quickly tracing and solving problems when product quality problems occur, affecting the production efficiency and product reliability.

[0007] In summary, the existing manual assembly of T-valves has obvious deficiencies in terms of numerous inspection items, complex inspection processes, large investment in human resources, and lack of effective traceability means. These problems not only increase production costs but also affect product quality control and production efficiency. Therefore, there is an urgent need for an improved technical solution to address these deficiencies in the existing technology and improve the production efficiency and product quality of T-valve assembly. At the same time, the improved technical solution should ensure that when the T-valve is used as a pressure relief valve, it can perform its function of protecting system safety more efficiently and reliably.

The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items.

[0048] Before describing the implementation in detail, in order to facilitate understanding of this embodiment, the structure of the T valve is briefly described first. Structurally, the T valve includes a paper core formed by stacking multiple layers of paper strips, an integrated plunger, and a shell with a spring. The paper core is the core part of the T valve and is stacked with multiple layers of high-strength wear-resistant paper material. Through precision processing and stacking, these paper strips form a solid core. The arrangement and stacking of the paper strips are strictly designed to ensure that the paper core has sufficient strength and density to meet the use requirements of the valve.

[0049] The plunger is an important part of the T valve, usually made of polymer plastic material with high strength and corrosion resistance. The plunger is precisely machined to fit closely with the paper core and the shell.

[0050] The housing is made of high-strength engineering plastics. Inside the housing, there is a spring which provides elastic support through the support and fixation on the inner wall of the housing. At the top and bottom of the housing, there are connecting ports respectively, which are used to connect with other pipelines or devices to ensure the smooth flow of the medium. The housing plays a role of protection and sealing. Through the pressure of the spring, it ensures the tight fit between the paper core and the plunger, preventing the leakage of the medium. The housing also provides a stable support environment, enabling the valve to work properly under various complex working conditions.

[0051] The spring is usually made of high-strength steel wire and has good elasticity and durability. The spring is installed inside the housing and its position is kept stable through the fixing structure on the inner wall of the housing. The spring provides the necessary elastic force to ensure the sealing performance of the valve when it is closed, preventing the leakage of the medium. Embodiment

[0052] As Figures 1 to 9 shown, this embodiment discloses an exemplary structure of an automatic assembly and detection line for valve bodies. In the specific structure, as Figures 1 to 3 shown, it includes a control host (not shown in the figure) and a plunger paper sheet detector 2, a spring housing detector 1, a T-valve finished product assembly detector 3, and a finished product palletizer 4 which are connected in sequence under its control. Each detector is provided with an independent circulating conveyor line 5. There are carriers 501 on each independent circulating conveyor line 5 and they are adjacent in sequence, and the material transfer between adjacent circulating conveyor lines 5 is realized by a transfer device 6. This assembly and detection line reduces manual operation through automated equipment, improving production efficiency and product quality.

[0053] More specifically, in this embodiment, the circulating conveyor line 5 controlled by the control host realizes continuous operation between each working station to ensure the independence and efficient operation between each process. The material transfer between each machine is realized through the transfer device 501, that is, it is transferred from one circulating conveyor line 5 to the adjacent next circulating conveyor line 5, thus ensuring the smooth progress of the entire production process.

[0054] In terms of the specific structure, each circulating conveyor line 5 mainly consists of a conveyor belt, a carrier 501, a driving device, a guiding device, and a sensor. Each part coordinates with each other to ensure the efficient operation of each independent working station, and realizes the material transfer between adjacent working stations through the transfer device.

[0055] The conveyor belt is the core component of the circulating conveyor line. It is made of wear-resistant and high-temperature-resistant polyurethane material to ensure the durability of long-term operation. The conveyor belt runs in a loop along a preset track, forming a closed-loop system. Each circulating conveyor line 5 is equipped with an independent driving device, which can be independently controlled for the running speed and direction according to needs, so as to adapt to the requirements of different processes.

[0056] The carrier 501 is installed on the conveyor belt and is used to carry the components to be detected and assembled. The carrier 501 is made of high-strength aluminum alloy or stainless steel materials to ensure stability and durability.

[0057] During implementation, as an optimization, each carrier 501 is provided with a positioning pin and a fixture to ensure that the components do not shift or tilt during transportation.

[0058] As a further description, the driving device includes a motor, a reducer, a conveyor belt, etc. The motor drives the conveyor belt to run, and the reducer adjusts the running speed to ensure the smooth operation of the conveyor belt. Each independent driving device is distributed at the key nodes of the conveyor line to provide sufficient power and precise speed control to meet the requirements of different processes.

[0059] More specifically, the guiding device consists of a guide rail and guide wheels to ensure the smooth operation of the conveyor belt along a predetermined track. The guide rail is made of high-strength steel, and the guide wheels are connected through rolling bearings to reduce friction and wear, improving the running efficiency and service life. The guiding device ensures that the conveyor belt can still maintain stability during high-load and high-speed operation.

[0060] In addition, sensors are used to detect information such as the position of the carrier, the state of the components, and the running speed, etc., to ensure the precise control of the entire conveyor line. Commonly used sensors include photoelectric sensors, magnetic induction sensors, and encoders, etc. The sensors feed back the detected information to the control system in real time to achieve automated control and monitoring, improving the intelligent level and response speed of the system.

[0061] The independent loop conveyor line on each inspection machine realizes material transfer through a transfer device. The transfer device includes a transfer robot, a transfer track, and a transfer control system. The transfer robot uses a multi-axis robotic arm installed on the transfer track to grab the components on the carrier from the end of one loop conveyor line and transfer them to the starting point of the adjacent next loop conveyor line. The transfer control system precisely controls the grasping, moving, and releasing actions of the transfer robot according to the information fed back by the sensors to ensure the stability and accuracy of the components during the transfer process.

[0062] During actual operation, the independent loop conveyor line 5 on each inspection machine drives the conveyor belt to run through the driving device, and the carrier 501 moves accordingly, sequentially conveying the components at each work station to the corresponding positions. The sensors continuously monitor the states of the carrier and the components and feed back the information to the control host. The control host adjusts the operating parameters of the driving device according to the information fed back by the sensors to ensure the synchronization and coordination of each work station.

[0063] In the specific operation steps, during initial feeding, the component to be processed (plunger) is placed on the starting stage 501 of the first circulating conveyor line 5. After the sensor detects that there is material on the stage 501, the control host starts the driving device, and the conveyor belt begins to run. The stage 501 passes through each working station in sequence. After the sensor at each working station detects the arrival of the stage 501, the control host pauses the conveyor belt, and the station equipment starts to perform corresponding operations on the component, such as detection, assembly, etc. After each working station completes the operation, the sensor feeds back the status information of the component to the control host. The control host determines whether it meets the requirements based on the feedback information. If it meets the requirements, the driving device continues to operate and conveys the stage 501 to the next working station; if it does not meet the requirements, the control host issues an alarm and stops running, waiting for manual processing or automatic correction. After the component completes the operation on the circulating conveyor line 5 of one inspection machine, the transfer device 6 transfers the component from the end of this inspection machine to the starting point of the circulating conveyor line 5 of the adjacent inspection machine to continue the next operation. After all the working stations complete the operations, the finished component (valve) is automatically taken out and palletized by the finished product palletizing machine 4.

[0064] As shown in Figures 1 to 6 In this embodiment, the plunger paper sheet inspection machine 2 is an important part of the valve body automatic assembly and inspection line, and its structure includes a plunger feeding and inspection module 201 and a paper sheet feeding, assembly and inspection module 202. The plunger feeding and inspection module 201 is composed of a first vibrating discharging device, a transfer robot 203, a visual diameter inspection component 204, an appearance flatness inspection component 205 and a roughness inspection component 206. The first vibrating discharging device discharges the plungers in sequence. The control host intermittently (i.e., spot-checks) grabs the plungers through the transfer robot 203 and sends them into the roughness inspection component 206. After passing the inspection, they are sent into the visual diameter inspection component 204. Similarly, after passing the inspection, they enter the appearance flatness inspection component 205 to sequentially inspect the roughness, diameter, thickness and flatness of the plungers, achieving detailed inspection to ensure that all parameters of the plungers meet the requirements.

[0065] It can be understood that the working purpose of the plunger paper sheet inspection machine 2 is to improve the inspection and assembly efficiency of the plunger and the paper sheet through automated equipment, reduce manual operations, and improve product quality. In the traditional manual inspection and assembly process, it is easy to have situations of misinspection and missed inspection. Automated inspection and assembly not only improve the accuracy and consistency of inspection, but also greatly improve production efficiency. The sensor monitors the status of each component in real time and feeds back the information to the control system to ensure the smoothness and high efficiency of the whole process.

[0066] In the above structure, the main function of the transfer robot 203 is to transfer the plunger to ensure the continuity and high efficiency of the production process. In terms of the specific structure, the transfer robot 203 includes a three-axis robotic arm, a gripper, a camera and a control system, etc. Each part cooperates with each other to achieve efficient and precise material transfer.

[0067] During implementation, for layout requirements, to achieve transfer detection, it also includes a material transfer mechanism with a slide rail that cooperates with the transfer robot 203. The structure of this material transfer mechanism is conventional. As long as its transfer purpose can be achieved, no detailed description will be given here.

[0068] More specifically, the linear guide rail is a basic part of the transfer robot, usually made of high-strength steel to ensure stable and smooth movement under high loads. As the movement track of the robotic arm, the guide rail undergoes precision machining and lubrication treatment, and can withstand the rapid movement and frequent operation of the robotic arm, ensuring the smoothness and efficiency of the transfer process.

[0069] The three-axis robotic arm is the execution part of the transfer robot, with three degrees of freedom in the X, Y, and Z directions, capable of performing complex three-dimensional movements. Each joint of the robotic arm is driven by a high-precision servo motor to ensure the accuracy and stability of the movement. The material of the robotic arm is usually lightweight and high-strength aluminum alloy to reduce its own weight and improve the movement speed and response ability. A gripper and a camera are installed at the end of the robotic arm, responsible for grasping and identifying components.

[0070] The gripper is the grasping tool of the transfer robot, usually made of high-strength materials such as steel or carbon fiber to ensure that it can withstand greater forces during the grasping process. The design of the gripper takes into account the shape and material of the component, and has an adaptive function, which can be adjusted according to the size and shape of the component to ensure a firm grasp. Pressure sensors and position sensors are installed inside the gripper to monitor the grasping force and position in real time, preventing damage to the component.

[0071] The camera is the visual recognition tool of the transfer robot, usually a high-resolution industrial camera, installed at the end of the robotic arm or in an appropriate position, used to identify and locate components. The camera captures images of the components and transmits the image information to the control host. The control host uses image processing algorithms to analyze the position and posture of the components, guiding the robotic arm to perform precise grasping and transfer operations.

[0072] The working purpose of the transfer robot is to achieve the efficient transfer of components between various workstations through automated means, reduce manual operations, and improve production efficiency. In traditional manual operations, the transfer of components relies on manual labor, which is not only inefficient but also prone to operation errors, affecting the continuity of the production process and product quality. With the transfer robot, the transfer speed and accuracy can be greatly improved, the interference of human factors can be reduced, and the overall efficiency and stability of the production line can be enhanced.

[0073] In a more specific structure, the main function of the roughness detection component 206 is to detect the roughness of the plunger surface to ensure that the surface quality of the plunger meets the requirements.

[0074] First of all, it is necessary to understand that roughness inspection is the first step in sampling inspection.

[0075] In terms of structure, it includes a detection fixture and a stylus roughness detector for detecting the surface roughness of the plunger. The entire detection process is coordinated by a control host, and precise control is achieved through the information fed back by sensors.

[0076] The detection fixture is a device used to fix and position the plunger. It is usually made of high-strength materials such as stainless steel or hard aluminum alloy to ensure its stability and durability during the detection process. The detection fixture is equipped with precise clamps and positioning pins to firmly fix the plunger in the specified position, ensuring that the plunger does not displace or vibrate during the detection process.

[0077] The stylus roughness detector measures the surface roughness of the plunger through the scanning of a precision stylus. The stylus is made of high-hardness material and can withstand high-frequency scanning actions to ensure the accuracy and reliability of the detection. Under the control of an electric drive device, the stylus moves on the surface of the plunger along a set scanning path and speed, and the microscopic profile of the plunger surface is recorded in real time. The displacement sensor of the stylus converts the movement data of the stylus into an electrical signal and transmits it to the control host for processing and analysis.

[0078] The control host is responsible for receiving and processing the detection data from the stylus roughness detector, and can quickly analyze the movement data of the stylus to calculate the roughness parameters of the plunger surface. According to the preset quality standards, the control host compares the detection results with the standard values to judge whether the surface roughness of the plunger meets the requirements.

[0079] The purpose of the detection is to ensure that the surface quality of the plunger meets the technical requirements of the product. The surface roughness of the plunger directly affects the sealing performance and service life of the valve body. If the surface is too rough, it may cause the valve body to be poorly sealed, resulting in air leakage or liquid leakage; if the surface is too smooth, it may affect the lubrication effect and accelerate wear. Therefore, through roughness detection, unqualified plungers can be effectively screened out to ensure that only plungers with qualified surface quality enter the next process, thereby improving the overall quality of the finished valve body.

[0080] Through this efficient sampling roughness detection method, the production line can quickly screen out unqualified plungers to ensure that all plungers entering the next process in batches have good surface quality, thereby improving the efficiency of the entire production process and the final quality of the product.

[0081] In this embodiment, the visual diameter detection component 204 accurately measures the diameter of the plunger through vision technology to ensure that its size meets the predetermined specification requirements. The detection component includes a detection fixture, a light source, a camera, an image processing system and a control system, and each part cooperates with each other to achieve efficient and accurate diameter measurement.

[0082] The light source is an important part of the visual diameter detection component 204. It provides uniform and stable lighting conditions to ensure that the camera can clearly capture the image of the plunger. High-brightness LED lights are usually used as the light source, which have the advantages of high brightness, long lifespan, and low energy consumption. The position and angle of the light source are aimed at eliminating shadows and reflections, ensuring that the edge of the plunger is clearly visible, thereby improving the measurement accuracy.

[0083] The camera measures the diameter of the plunger by capturing an image of the plunger at a fixed position at a fixed height. High-resolution industrial cameras are usually used as the camera, which can capture the fine features of the plunger. The camera is installed above or on the side of the detection fixture. By cooperating with the light source, a clear image of the plunger is obtained. The position and focal length of the camera are precisely adjusted, and after adjustment, they are fixed to ensure the clarity and accuracy of the image.

[0084] The image processing system is integrated into the control host and is responsible for processing the images captured by the camera. Through a series of algorithms and technologies, the edge features of the plunger are extracted from the images, and the diameter of the plunger is calculated. The processing process includes steps such as image acquisition, preprocessing, edge detection, feature extraction, and dimension calculation, ensuring the accuracy and stability of the measurement results.

[0085] If the measurement result is within the allowable range, the plunger is judged to be qualified and can enter the next process; if it exceeds the standard range, the plunger is judged to be unqualified, marked as NG (unqualified) by the system, an alarm is issued, and it waits to be processed.

[0086] The purpose of visual diameter detection is to ensure that the size of the plunger meets the technical requirements, guarantee the accuracy of subsequent assembly and the quality of the product. The diameter of the plunger directly affects the assembly quality and performance of the valve body. Through precise diameter measurement, unqualified plungers in terms of size can be effectively screened out, preventing them from entering the next process, thereby improving the consistency and reliability of the product. Visual diameter detection has the advantages of high precision, high efficiency, and non-contact, which can greatly improve the detection speed and accuracy, and reduce the errors and omissions of manual detection.

[0087] In this embodiment, the paper sheet feeding and assembling detection module 202 of the plunger paper sheet detector 2 includes a second vibrating discharging device and a flexible feeding device 207. The second vibrating discharging device discharges the foam in sequence, and the flexible feeding device 207 grabs the foam and assembles it with the plunger in the carrier 501 at a specific station.

[0088] More specifically, a camera for identifying the position of the foam is provided inside the flexible feeding device 207. Through image recognition technology, the position and posture of the foam are ensured to be correct, guaranteeing the accuracy and consistency of the assembly.

[0089] In terms of specific structure, the flexible loading device 207 consists of the following main components: a camera, a robotic arm, a flexible fixture, and a control system. These components cooperate with each other to ensure the accuracy and efficiency of the loading process.

[0090] First of all, the camera in the flexible loading device 207 is a key device for identifying the position of the foam. The camera is installed above and uses image acquisition technology to monitor the specific position and posture of the foam in real time. After the camera captures the position of the foam, it transmits the image information to the control host. The control host analyzes the position and angle of the foam through image processing algorithms to determine the optimal grasping point. This process ensures that the foam can be accurately identified and positioned in any position and posture, providing reliable data support for subsequent grasping operations.

[0091] The robotic arm is the execution component of the flexible loading device 207. It is installed on a high-precision linear guide rail and can move smoothly along the guide rail. The robotic arm is equipped with a multi-axis motion module that can perform complex three-dimensional motions. This enables the robotic arm to move freely in all directions with extremely high flexibility. A flexible fixture is installed at the end of the robotic arm. The flexible fixture is made of high-elasticity material and can be adaptively adjusted according to the shape and size of the foam to ensure the stability and reliability of the grasping process. Under the command of the control host, the robotic arm accurately moves to the position of the foam according to the position information provided by the camera and firmly grasps the foam through the flexible fixture.

[0092] The flexible fixture is an important component in the flexible loading device 207. It can be finely adjusted during the grasping process through pneumatic or electric control to adapt to foams of different sizes and shapes. The design of the flexible fixture takes into account the force and angle during the grasping process to ensure that the foam will not be damaged when grasped. Pressure sensors and displacement sensors are installed inside the fixture to monitor the grasping force and displacement in real time and feed the data back to the control host. The control host makes real-time adjustments according to the feedback data to ensure the accuracy and stability of the grasping action.

[0093] It can be understood that the working principle of the flexible loading device 207 is an automated process based on image recognition and precise control. First, the camera captures the position and posture of the foam and transmits the image information to the control system. The control system analyzes the image information and generates the motion trajectory of the robotic arm. The robotic arm moves to the position of the foam under the command of the control system, grasps the foam through the flexible fixture, and accurately places it on the plunger. The entire process is monitored and adjusted in real time by the control system to ensure the efficiency and accuracy of each link.

[0094] The working purpose of the flexible feeding device 207 is to achieve precise feeding and assembly of the foam through automated means, improving production efficiency and product quality. Traditional manual feeding methods have problems such as low efficiency, poor accuracy, and easy errors. The flexible feeding device significantly improves the feeding accuracy and efficiency through automated technology, reducing the errors of manual operations. At the same time, through flexible jigs and high-precision control systems, it ensures that the grasping and assembly of each piece of foam can meet high-standard quality requirements.

[0095] More specifically, the main function of the appearance flatness detection component 205 is to detect the flatness of the plunger surface to ensure that the appearance quality of the plunger meets the requirements. This detection component includes parts such as a detection fixture, a digital displacement sensor, a detection fixture fixing device, and a control system. Each part cooperates with each other to achieve efficient and precise appearance flatness detection.

[0096] The digital displacement sensor is used to measure the flatness of the plunger surface. The digital displacement sensor calculates the flatness value of the plunger surface by detecting the height difference between different points on the plunger surface. The sensor is installed above or on the side of the detection fixture and can move vertically or horizontally during the detection process. The accuracy and resolution of the digital displacement sensor are very high, capable of detecting height differences at the micron level, ensuring the accuracy of the measurement results.

[0097] The detection fixture fixing device is used to fix and adjust the position of the detection fixture to ensure that the fixture remains stable during the detection process. The fixing device usually uses high-precision guide rails and locking mechanisms, which can precisely adjust the position of the fixture before the detection starts and remain stationary during the detection process. The design of the fixing device takes into account the stability and repeatability of the detection, ensuring the reliability of each detection result.

[0098] The working principle of appearance flatness detection is based on height measurement technology. By detecting the height difference between different points on the plunger surface with a digital displacement sensor, the measurement of flatness is achieved. When the plunger enters the detection station, the detection fixture fixes it in the designated position. Under the command of the control system, the digital displacement sensor starts to scan the plunger surface and records the height data of different points. The displacement data of the sensor is transmitted to the control system through electrical signals, and the control host can quickly analyze these data and calculate the flatness value of the plunger surface. According to the preset quality standard, the control host compares the detection result with the standard value to judge whether the flatness of the plunger meets the requirements.

[0099] The purpose of the detection is to ensure that the surface flatness of the plunger meets the technical requirements of the product. The surface flatness of the plunger directly affects the assembly quality and service performance of the valve body. If the surface is uneven, it may lead to loose assembly of the valve body, resulting in air leakage or liquid leakage. Therefore, through the appearance flatness detection, the plungers with unqualified surfaces can be effectively screened out, ensuring that only the plungers with qualified surface flatness enter the next process, thus improving the overall quality of the finished valve body.

[0100] In this embodiment, the main function of the paper sheet feeding and assembling detection module 202 is to feed the paper sheets in sequence, assemble them into a paper core and conduct detection to ensure the quality of the paper sheets and the accuracy of the assembly. This module includes parts such as a paper sheet vibrating disk 208, a PPU feeding mechanism 209, a rotary assembling disk 210, a detection component and a core transferring mechanism, etc. Each part cooperates with each other to achieve efficient and precise paper sheet feeding and assembling detection.

[0101] Firstly, the paper sheet vibrating disk 208 is an important part of the paper sheet feeding. The paper sheet vibrating disk 208 is driven by a motor to generate high-frequency vibration, making the paper sheets move in sequence along the preset track. The track design of the vibrating disk takes into account the size and shape of the paper sheets, which can ensure that the paper sheets will not turn over or overlap during the movement, guaranteeing the order and stability of the paper sheets. The vibrating disk sends out the paper sheets in sequence, providing a reliable basis for subsequent feeding and assembling.

[0102] The PPU feeding mechanism 209, also known as the Pick and Place Unit, is a device responsible for grasping the paper sheets from the paper sheet vibrating disk 208 and sending them to the assembling position. The PPU feeding mechanism 209 consists of a multi-axis robotic arm, a flexible fixture and a control system. The multi-axis robotic arm can move flexibly in three degrees of freedom. The fixture is made of flexible materials and can be adaptively adjusted according to the shape and size of the paper sheets to ensure firm grasping of the paper sheets. Under the command of the control system, the PPU feeding mechanism 209 grasps the paper sheets from the paper sheet vibrating disk 208 and sends them to the designated position of the rotary assembling disk 210 according to the preset track and sequence.

[0103] More specifically, the working principle of the PPU loading mechanism 209 is based on visual recognition and precise control. The camera captures the image of the paper sheet, and the image processing algorithm is used to extract the position and attitude information of the paper sheet. Then, the control system guides the robotic arm to perform the grasping operation. When the paper sheets are arranged in sequence on the vibrating paper sheet tray, the camera takes pictures of the paper sheets, and the image processing unit analyzes the images to extract the position information of the paper sheets. According to this information, the control system generates the motion trajectory of the robotic arm. Under the instruction of the control system, the robotic arm moves to the position of the paper sheet. The flexible fixture adjusts according to the thickness and shape of the paper sheet to firmly grasp the paper sheet. Subsequently, the robotic arm moves the paper sheet to the designated position on the rotary assembly tray 210 along the preset trajectory and places it precisely. The whole process is monitored and adjusted in real time by the control system to ensure the efficiency and accuracy of each link.

[0104] The working purpose of the PPU loading mechanism 209 is to achieve precise loading of paper sheets through automated means, improving production efficiency and product quality. In traditional manual operations, the loading of paper sheets relies on manual labor, which is not only inefficient but also prone to operational errors, affecting the continuity of the production process and product quality. With the PPU loading mechanism, the loading speed and accuracy can be significantly improved, reducing the interference of human factors and enhancing the overall efficiency and stability of the production line.

[0105] A number of rod shafts are evenly distributed on the rotary assembly tray 210 for fixing and supporting the paper sheets. Driven by the rotating mechanism, the rotary assembly tray 210 can perform precise rotation and positioning. The paper sheets are sent into the rod shafts by the PPU loading mechanism 209 and stacked together to form a paper core.

[0106] The detection component is a device responsible for detecting the quality of the paper core, usually including a visual detection system and a pressure detection system. The visual detection system consists of a high-resolution camera and an image processing system, which is used to detect the appearance quality of the paper core, such as whether the paper sheets are neatly arranged and whether there are defects. The camera captures the image of the paper core and transmits it to the image processing system for analysis and judgment. The pressure detection system applies a certain pressure to the paper core to detect the thickness and density of the paper core, ensuring that the assembly quality of the paper core meets the requirements. The design and installation position of the detection component take into account the accuracy and stability of detection, and can complete high-precision detection in a short time.

[0107] The core transfer mechanism is a device responsible for transferring the assembled and inspected paper cores to the next process, usually consisting of a multi-axis robotic arm, a fixture, and a control system. The multi-axis robotic arm can move flexibly in three degrees of freedom. The fixture is made of flexible material and can firmly grasp the paper core. Under the command of the control system, the core transfer mechanism grabs the paper core from the assembly tray and transfers it to the designated position on the circular conveyor line according to the preset trajectory and sequence. The design of the core transfer mechanism takes into account the size and shape of the paper core to ensure stability and accuracy during the transfer process.

[0108] When the paper piece feeding, assembling and inspecting module 202 is working. When the paper pieces enter the paper piece vibrating bowl 208, the vibrating bowl sends out the paper pieces in sequence through high-frequency vibration. Under the command of the control host, the PPU feeding mechanism 209 grabs the paper pieces from the vibrating bowl and sends them to the designated position of the rotary assembly tray 210. After assembly, the assembly tray rotates to the next station according to the preset program. The inspection component inspects the appearance and thickness of the paper core to ensure that its quality meets the requirements. The core transfer mechanism transfers the qualified paper cores to the next process, and the whole process is monitored and adjusted in real time by the control host to ensure the efficiency and accuracy of each link.

[0109] In this embodiment, the main function of the spring housing inspection machine 1 is to assemble and inspect the spring and the housing to ensure that the assembly quality meets the technical requirements. The inspection machine includes parts such as an assembly fixture, a housing vibrating bowl, a spring vibrating bowl, a spring transfer mechanism, a housing transfer mechanism, a vision inspection system, and a control system. Each part cooperates with each other to achieve efficient and precise assembly and inspection.

[0110] The housing vibrating bowl is a device for sending out the housings in sequence. It is usually made of high-strength material to ensure its stability and durability under high-frequency vibration. The housing vibrating bowl is driven by a motor to generate high-frequency vibration, so that the housings move along the preset track in sequence. The track design of the vibrating bowl takes into account the size and shape of the housings to ensure that the housings will not turn over or overlap during the movement, and to ensure the sequence and stability of the housings. The housing vibrating bowl sends out the housings in sequence, providing a reliable basis for subsequent transfer and assembly.

[0111] The spring vibrating bowl is a device for sending out the springs in sequence. Its design and working principle are similar to those of the housing vibrating bowl. The spring vibrating bowl moves the springs along the preset track in sequence through high-frequency vibration, ensuring that each spring can reach the designated position smoothly. The design of the spring vibrating bowl takes into account the size and shape of the springs to ensure that the springs will not be distorted or stuck during the movement, and to ensure the sequence and stability of the springs.

[0112] The spring transfer mechanism is a device responsible for grasping springs from the vibrating bowl and feeding them into the assembly jig. It usually consists of a multi-axis robotic arm, a flexible fixture, and a control system. The multi-axis robotic arm can move flexibly in multiple degrees of freedom. The fixture is made of flexible materials and can adaptively adjust according to the shape and size of the spring to ensure stability and reliability during the grasping process. Under the command of the control system, the spring transfer mechanism grasps the springs from the vibrating bowl and feeds them into the specified position of the assembly jig according to the preset trajectory and sequence.

[0113] The housing transfer mechanism is a device responsible for grasping the housings from the vibrating bowl and feeding them into the assembly jig. Its structure and working principle are similar to those of the spring transfer mechanism. The housing transfer mechanism uses a multi-axis robotic arm and a flexible fixture to grasp the housings from the vibrating bowl and feed them into the specified position of the assembly jig, ensuring that each housing can be accurately placed in position, providing guarantee for subsequent assembly and inspection.

[0114] The vision inspection system is a device used to detect the assembly quality of springs and housings. It usually includes a high-resolution camera and an image processing system. The camera is installed above or on the side of the assembly jig and can monitor the components during the assembly process in real time. The image processing system analyzes the images captured by the camera to detect the assembly quality of springs and housings, such as whether the position is correct and whether the assembly is tight. The design and installation position of the vision inspection system take into account the accuracy and stability of detection, and can complete high-precision detection in a short time.

[0115] The working principle of the spring-housing inspection machine 1 is based on precise mechanical and control technologies. It realizes the efficient assembly of springs and housings through the transfer mechanism and the assembly jig, and conducts quality inspection through the vision inspection system. When the housings and springs enter their respective vibrating bowls, the vibrating bowls send out the housings and springs in sequence through high-frequency vibration. Under the command of the control system, the spring transfer mechanism and the housing transfer mechanism grasp the components from the vibrating bowls and feed them into the assembly jig. The assembly jig pushes the springs into the housings to form a combined body. The vision inspection system monitors the components during the assembly process in real time and detects the assembly quality. The control system judges whether the components meet the requirements according to the detection results. If the detection results are within the allowable range, the components are judged to be qualified and can enter the next process; if they exceed the standard range, the components are judged to be unqualified, marked as NG by the system, an alarm is issued, and they wait for processing.

[0116] More specifically, the vision waiting tray and the spring transfer mechanism are important components of the spring-housing inspection machine, mainly responsible for sending out the springs in sequence and accurately transferring them into the assembly jig. The two cooperate with each other to ensure the efficiency and accuracy of the springs during the entire transfer and assembly process.

[0117] The visual buffer tray is a device used for temporarily storing and organizing springs, ensuring that the springs are neatly arranged before entering the transfer mechanism. The buffer tray is usually made of wear-resistant materials such as stainless steel or hard plastic to ensure its durability and stability under high-frequency use. A vibration device is installed at the bottom of the buffer tray, which makes the springs arranged in order in the buffer tray and move to the designated position through high-frequency vibration. A high-resolution camera is installed above the visual buffer tray, which is responsible for monitoring the springs in the buffer tray in real time.

[0118] The spring images captured by the camera are analyzed by the image processing system to extract the position, angle, and posture information of the springs. The image processing system uses advanced image processing algorithms to quickly and accurately identify the specific positions of each spring and transmits this information to the control system. Based on this data, the control system generates corresponding control instructions to guide the precise operation of the spring transfer mechanism.

[0119] The spring transfer mechanism is a device responsible for grasping the springs from the visual buffer tray and feeding them into the assembly fixture. It mainly consists of a multi-axis robotic arm, a flexible fixture, and a control system. The multi-axis robotic arm usually has three degrees of freedom in the X, Y, and Z directions and can move flexibly in three-dimensional space. Each joint of the robotic arm is driven by a high-precision servo motor to ensure the accuracy and stability of the movement. The material of the robotic arm is usually lightweight and high-strength aluminum alloy to reduce its own weight and improve the movement speed and response ability.

[0120] The flexible fixture is a grasping tool at the end of the robotic arm, made of high-strength and elastic materials such as polyurethane or rubber. The design of the fixture takes into account the shape and size of the springs and can be adjusted adaptively according to the thickness and shape of the springs to ensure the stability and reliability during the grasping process. Pressure sensors and position sensors are installed inside the fixture to monitor the grasping force and position in real time to prevent damage to the springs.

[0121] During the specific operation process, the visual buffer tray arranges the springs in order through the vibration device and moves them to the camera monitoring area. The spring images captured by the camera are transmitted to the image processing system, and after analysis, the system transmits the position and posture information of the springs to the control system. The control system generates the movement trajectory of the robotic arm based on this information, and the robotic arm moves to the spring position under the instructions of the control system.

[0122] The flexible fixture adjusts according to the shape and size of the springs and firmly grasps the springs. Subsequently, the robotic arm moves the springs to the designated position of the assembly fixture along the preset trajectory and places them precisely. The entire process is monitored and adjusted in real time by the control host to ensure the efficiency and accuracy of each link.

[0123] The beneficial effects include improving the speed and accuracy of spring transfer and assembly, ensuring that each spring can be accurately positioned and stably grasped before assembly, and reducing assembly problems caused by human operation errors. The close cooperation between the visual stock tray and the spring transfer mechanism enables the spring housing inspection machine to operate efficiently in a complex production environment, providing a reliable guarantee for the high-efficiency production of the valve body automatic assembly and inspection line.

[0124] In the above structure, the rotary inspection table provides an efficient inspection method through precise rotation and 3D vision inspection to ensure the assembly quality. The following is a detailed description of the rotary inspection table and its inspection purposes and functions.

[0125] The rotary inspection table consists of a rotary mechanism, an inspection fixture, and a high-resolution camera.

[0126] The rotary mechanism is the core component of the rotary inspection table and is usually composed of a high-precision electric turntable and a transmission device. The rotary mechanism can accurately rotate the housing at a set speed and angle to ensure a comprehensive inspection of the housing at different angles. The electric turntable is driven by a servo motor and has the characteristics of high precision, enabling a smooth and uniform rotational movement.

[0127] The high-resolution camera is the core device for visual inspection and is usually installed above or on the side of the rotary inspection table. It can capture omnidirectional images of the housing during rotation. The camera is equipped with a high-precision lens and a light source system to ensure clear capture of the details of the housing at different angles. The high resolution and fast capture ability of the camera enable it to complete a comprehensive scan of the housing in a short time.

[0128] The 3D image processing system is responsible for processing the images captured by the camera and generating 3D visual images of the housing. The control host extracts the geometric features and surface details of the housing through the 3D visual images and generates a three-dimensional model. Through the 3D visual images, the system can comprehensively inspect the size, shape, surface defects, etc. of the housing. The inspection includes the size, shape, surface defects, etc. of the housing, and the system will compare the inspection results with the preset standards.

[0129] In this embodiment, the main function of the T-valve finished product assembly inspection machine 3 is to comprehensively inspect the assembled T-valve to ensure that its quality and performance meet the technical requirements. The inspection machine includes parts such as an airtightness inspection component, an assembly inspection component, a liquid leakage inspection component, and a two-dimensional code engraving component. Each part cooperates with each other to achieve efficient and accurate finished product inspection.

[0130] The airtightness detection component is the first detection link of the T-valve finished product assembly detection machine, mainly used to detect the sealing performance of the T-valve. This component usually includes an airtightness detector, a sealing fixture, and a control system. The airtightness detector detects whether there is leakage in the valve body by filling a certain pressure of air or gas into the T-valve. The sealing fixture is used to fix the T-valve and ensure the stability of the valve body during the detection process. The control system judges the detection results according to the preset airtightness standard. If the detected leakage amount is within the allowable range, the T-valve passes the airtightness detection; otherwise, the system will give an alarm and mark it as a non-conforming product.

[0131] The assembly detection component is used to detect the appearance and overall assembly quality of the T-valve. This component usually includes a rotating seat, a camera, a flipping mechanism, and an image processing system. The rotating seat is used to fix the T-valve and make it rotate 360 degrees during the detection process to ensure that the camera can capture all angles of the valve body. The camera is installed around the rotating seat and takes pictures of the appearance and assembly of the T-valve from multiple angles. The flipping mechanism is used to flip the T-valve at different angles to ensure comprehensive detection. The control host analyzes the images captured by the camera to detect whether there are defects in the appearance of the T-valve and whether the assembly is correct. If the detection results meet the requirements, the T-valve passes the assembly detection; otherwise, the system will give an alarm and mark it as a non-conforming product.

[0132] The liquid leakage detection component is used to detect whether the T-valve will leak liquid during actual use. This component usually includes a liquid leakage detector, a sealing fixture, and a control system. The liquid leakage detector injects a certain amount of liquid into the T-valve to detect the sealing performance of the valve body and the liquid flow situation. The sealing fixture is used to fix the T-valve and ensure the stability of the valve body during the detection process. The control system judges the detection results according to the preset liquid leakage standard. If the detected liquid leakage amount is within the allowable range, the T-valve passes the liquid leakage detection; otherwise, the control host will give an alarm and mark it as a non-conforming product.

[0133] The QR code engraving component is used to engrave a unique QR code identification on the qualified T-valve for subsequent product traceability and quality management. This component usually includes a QR code engraving machine, a positioning fixture, and a control system. The QR code engraving machine engraves a unique QR code identification on the specified position of the T-valve by laser or other engraving technologies. The positioning fixture is used to fix the T-valve and ensure the stability of the valve body during the engraving process. The control host controls the operation of the QR code engraving machine according to the preset engraving standard and records the QR code information of each T-valve.

[0134] The purpose of detection is to ensure that the quality and performance of the T-valve meet the technical requirements, and to ensure that every T-valve leaving the factory has undergone strict quality inspection and meets the needs of customers and the market. Through airtightness detection, the sealing performance of the T-valve can be guaranteed, and gas or liquid leakage during use can be avoided. Through assembly detection, the appearance and assembly quality of the T-valve can be guaranteed, ensuring the aesthetics and usability of the product. Through liquid leakage detection, it can be ensured that the T-valve will not leak liquid during actual use, improving the safety and reliability of the product. Through QR code engraving, traceability and management of each T-valve can be achieved, facilitating subsequent quality control and after-sales service.

[0135] In this embodiment, the main function of the finished product palletizing machine 4 is to sequentially place the qualified T-valve finished products that have passed all inspections into the specified trays, and after the tray is full, move it to the finished product stacking position for storage. Through automated operation, this equipment realizes efficient and precise placement and storage of finished products. The finished product palletizing machine 4 includes a servo slide, a clamping device, a suction cup, an interleaving paper placement mechanism, and a control system, etc.

[0136] The servo slide is one of the core components of the finished product palletizing machine, responsible for transporting the finished product from the detection position to the palletizing position. The servo slide is usually composed of a high-precision servo motor and a linear guide rail, and can achieve high-speed and precise linear motion. The servo motor drives the slide to move along the guide rail through a transmission mechanism, ensuring the smoothness and accuracy of the finished product during transportation. The movement trajectory and speed of the slide are precisely controlled by the control system to adapt to different requirements for placing finished products.

[0137] The clamping device is installed at the end of the servo slide and is used to grab and place the finished product T-valve. The clamping device is usually composed of a flexible fixture and a pressure sensor. The flexible fixture is made of high-strength and elastic materials, and can be adjusted adaptively according to the shape and size of the T-valve, ensuring the stability and reliability during the grabbing process. The pressure sensor monitors the grabbing force in real time to prevent damage to the finished product. Under the command of the control system, the clamping device accurately grabs the finished product T-valve and transports it to the palletizing position.

[0138] During the process of palletizing the finished product, the clamping device grabs the qualified T-valve finished products that have passed all inspections from the detection position and sequentially places them into the trays according to the preset order and position. The control host accurately calculates the placement position of each T-valve according to the layout of the tray and the size of the finished product, ensuring neat and orderly placement. When a tray is full, the system will send a signal to start the next operation.

[0139] The suction cup is a device used to place separator paper, usually composed of a vacuum generator and a flexible suction cup. The vacuum generator generates negative pressure, enabling the suction cup to firmly adsorb the separator paper. The flexible suction cup is made of high-elasticity material and can adapt to separator papers of different thicknesses and materials. After the tray is filled with finished products, the suction cup device starts. The suction cup sucks the separator paper from the paper stack above the tray and moves it to the top of the full tray to place the separator paper.

[0140] The separator paper placement mechanism ensures that there is separator paper between each layer of finished products to prevent the finished products from being squeezed and damaged during storage. The placement position of the separator paper is precisely controlled by the control system to ensure that the separator paper covers the entire top of the tray, preparing for the placement of the next layer of finished products.

[0141] When a tray is filled with finished products and the separator paper is placed, the sliding table moves the full tray into the finished product stacking position for storage. The movement trajectory and speed of the sliding table are precisely controlled by the control system to ensure the smoothness and accuracy of the full tray during the transfer process. The finished product stacking position is usually equipped with multiple storage positions to facilitate the classification and management of finished products. The sliding table moves the full tray to the designated storage position and performs the stacking operation.

[0142] The function of the finished product placing machine is to achieve the efficient placement and storage of T-valve finished products through automated means, improving production efficiency and product quality. In traditional manual operations, the placement and storage of finished products rely on manual labor, which is not only inefficient but also prone to operational errors, affecting the continuity of the production process and product quality. Through the finished product placing machine, the speed and accuracy of placing and storing finished products can be significantly improved, reducing the interference of human factors and enhancing the overall efficiency and stability of the production line.

[0143] In this embodiment, the control host is the core of the valve body automatic assembly and detection line, responsible for coordinating and controlling the operation of each device to ensure the efficient and precise operation of the entire system. The following is a detailed description of the control host:

[0144] The control host includes a central processing unit (CPU), a storage device, an input / output module (I / O module), a human-machine interface (HMI), and a communication module.

[0145] The central processing unit (CPU) is the core component of the control host, responsible for executing the control program, processing data from various sensors, and generating control instructions according to preset logic and algorithms. This CPU is usually a high-performance, multi-core processor that can handle complex control tasks and large amounts of data operations to ensure the real-time response and efficient operation of the system.

[0146] The storage device is used to store control programs, operating systems, device parameters, and production data. The storage device includes a solid-state drive (SSD) and memory (RAM), ensuring high-speed and stable data reading and writing. The stored production data can be used for subsequent analysis and optimization to improve the performance and efficiency of the system.

[0147] The input / output module (I / O module) realizes signal exchange between the control host and various devices. The I / O module includes digital and analog input / output interfaces, supporting multiple communication protocols (such as Ethernet, RS232, RS485, CAN, etc.), ensuring compatibility with different devices. These modules achieve precise control of the entire system by collecting sensor data and sending control instructions.

[0148] The human-machine interface (HMI) provides a user operation and monitoring interface, displaying device status, production parameters, alarm information, etc. The HMI usually adopts a touch-screen design with a friendly graphical interface and simple operation. Through the HMI, users can view the operating status and production data of the device in real time, perform parameter settings and operation control, and handle faults and alarm information.

[0149] The communication module realizes data exchange between the control host and external systems (such as enterprise management systems, databases, etc.), supporting wireless and wired communication methods, and featuring high bandwidth and low latency. Through the communication module, the control host can upload production data to the enterprise management system in real time, enabling remote monitoring and management.

[0150] The functions of the control host include real-time monitoring and control, data processing and storage, user operation and monitoring, alarm and fault handling, as well as system integration and data exchange. The control host receives data from various detectors, transfer mechanisms, and sensors in real time to monitor the operating status of the device. According to preset control logics and algorithms, it generates and sends control instructions to coordinate the operation of each device. It processes and analyzes sensor data to identify abnormal situations during device operation and makes corresponding adjustments. Through the human-machine interface (HMI), users can perform parameter settings, device control, and status monitoring. The control host has a perfect alarm and fault handling mechanism, which can send alarm signals in a timely manner when the device operates abnormally and record fault information. Through the communication module, it realizes data exchange with external systems, supporting real-time upload of production data and remote monitoring of device status.

[0151] The operating principle of the control host is based on real-time data acquisition, processing, and feedback control. The specific operation process is as follows: The control host collects sensor data from each detector, transfer mechanism, and finished product palletizing machine in real-time through the input / output module (I / O module). This data includes the operating status of the equipment, production parameters, detection results, etc. The control host processes and analyzes the collected data to identify the operating status and abnormal conditions of the equipment. The central processing unit (CPU) executes the control program and processes and calculates the data according to the preset logic and algorithms. Based on the results of data processing, the control host generates corresponding control instructions. These instructions include starting or stopping the equipment, adjusting operating parameters, triggering alarms, etc. The control instructions are sent to each device through the output module (I / O module) to control it to perform corresponding operations. The equipment adjusts its status or performs operating operations according to the received instructions.

[0152] During implementation, the control host monitors the operating status of the equipment in real-time and evaluates the execution effect of the control instructions through sensor data feedback. If any abnormalities or deviations are found, the control host will make adjustments according to the preset logic to ensure the stable operation of the system. Through the human-machine interface (HMI), users can view the operating status of the equipment, production data, and alarm information in real-time. Users can also perform parameter settings, equipment control, and fault handling through the HMI. The control host stores the key data generated during the production process in the local storage device and uploads the data to the enterprise management system or database through the communication module to support the real-time upload of production data and remote monitoring of the equipment status.

[0153] It should be understood that within the control host, this application does not specifically limit to a certain specific control software, control program, or PLC control program because these programs can be implemented using existing technologies or common knowledge. Therefore, this application does not describe the specific software, control program, or PLC control program in detail.
