[0002] In a conventional valve body production process, the detection process of the valve body is an extremely important link. The valve body detection process is usually carried out after the valve body production is completed, mainly to detect the appearance of the valve body in terms of whether the parts of the valve body are missing and the assembly accuracy of the valve body, etc. At the same time, the functional (airtightness) detection of the valve body is also an important control process to ensure the quality of the valve body. After the above two valve body detection processes are completed, the valve body is usually classified into three categories: one category is the finished product that passes the two detection processes, one category is the substandard product that can be recycled and repaired, and the last category is the scrap product that fails to pass the detection and cannot be recycled.

DETAILED DESCRIPTION

[0034] Hereinafter, the present application will be further described with reference to the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined arbitrarily to form new embodiments without conflict.

[0035] The present application refers to Figure 1 As shown in the figure, the device comprises a conveying device 50 provided with a placing station for placing the valve body, a detection device for detecting the air tightness and appearance information of the valve body on the placing station, a carrying device for carrying the valve body on the placing station to a target position, and a controller in communication connection with the conveying device 50, the detection device and the carrying device, the conveying device 50 is used to drive the valve body on the placing station to move, the controller can control the conveying device 50 and the detection device to act to receive and analyze the detection information of the detection device, and obtain the target position information of the valve body conveying according to the detection information, and the controller can control the carrying device to act according to the target position information. In use, the valve body can be placed on the placing station, and then the conveying device 50 is started to drive the valve body on the placing station to reach the detection device and perform appearance detection and functional detection, after the two detections are completed, the controller receives the detection information of the detection device and analyzes whether the valve body is a finished product passing the detection, a recyclable defective product or a non-recyclable scrap product, and confirms the final target position of the valve body, and finally controls the carrying device to start and carry the valve body to the corresponding target position after grabbing it. Through the above setting, the valve body detection process is automated, not only reducing the labor intensity of the workers and improving the work efficiency, but also reducing the detection error through automatic analysis and classification, so that the quality of the valve body is higher.

[0036] The conveying device 50 in the embodiment is a rotating conveying device 50 which conveys the valve body on the placing station to the detection device through rotation. Through the above arrangement, the placing station can be arranged at the edge of the rotating conveying device 50, and the detection device and the carrying device are arranged at intervals around the rotating conveying device 50. In use, the rotating conveying device 50 can be rotated by a certain angle each time, so that the valve body on the placing station is aligned with the device in operation each time. This arrangement makes the overall device occupy less space, and the rotating mode makes the detection system form a cycle, improving the work efficiency. In other embodiments, the conveying device 50 can also be a linear conveying device 50 such as a conveyor belt, and the detection device and the carrying device are arranged on both sides of the linear conveying device 50, so as to complete the carrying and detection of the valve body.

[0037] The rotating conveying device 50 in the embodiment is shown in Figure 9 The specific structure includes a rotating platform 51 and a rotating driving device 52 for driving the rotating platform 51 to rotate. The rotating driving device 52 includes a worm gear transmission mechanism and a driving motor. The worm gear is coaxially arranged with the rotating platform 51, and the worm is connected with the output shaft of the driving motor through a shaft coupling. When the driving motor is started, the worm gear is driven to rotate, thereby realizing the rotation of the rotating platform 51. Through this rotating mode, the structure is simple, and the angle of rotation of the rotating platform can be accurately controlled, ensuring that the valve body on the placing station can be aligned with each device after each rotation. In other embodiments, the rotating conveying device 50 can also drive the gear transmission mechanism to act through the driving motor to realize the rotation of the rotating platform 51.

[0038] The rotating conveying device 50 in the embodiment is provided with a fixing device 31 for placing the valve body, wherein the placing station is arranged on the fixing device 31. Through this arrangement, the fixing device 31 for placing the valve body and the rotating conveying device 50 become separate arrangements. When detecting different valve bodies, the type of the fixing device 31 on the rotating conveying device 50 can be directly replaced to accommodate different types of valve bodies, so that the detection system can detect more types of valve bodies. Meanwhile, the rotating conveying device 50 in the embodiment is also provided with a plurality of fixing devices 31, wherein the plurality of fixing devices 31 are arranged at the edge of the rotating platform 51 and are arranged at intervals around the center of the rotating platform 51. By increasing the number of fixing devices 31 and arranging them at intervals, when the rotating conveying device 50 rotates each time, one fixing device 31 is rotated and conveyed to the position opposite each detection device and carrying device nearby, thereby greatly improving the efficiency of valve body detection.

[0039] The detection device in the embodiment includes a visual detection device 30 for collecting valve body images and a gas tightness detection device 40 for detecting the gas tightness of the valve body. The visual detection device 30 is used to detect the appearance of the valve body, such as whether the parts of the valve body are missing and the assembly accuracy of the valve body. After the image of the valve body is collected, the controller compares the collected image with the standard image to obtain the difference in appearance of the valve body. The gas tightness detection device 40 is mainly used to detect the functionality (gas tightness) of the valve body. After air is supplied to the valve body, the gas tightness detection device 40 detects the change in air pressure in the valve body, and the controller determines whether the air pressure changes to determine whether the gas tightness of the valve body is good.

[0040] The specific structure of the visual detection device 30 in the embodiment is shown in Figure 4 The visual detection device 30 includes an image collection device for collecting valve body images and a rotation driving device 32 for driving the valve body on the placement station to rotate so that the valve body is at different angles to the image collection device. The controller is in communication connection with the rotation driving device 32 and the image collection device and can control the rotation driving device 32 and the image collection device to collect images of the valve body at different angles. The controller can receive the images collected by the image collection device and compare the images with the standard images of the valve body. In the above-mentioned arrangement, the valve body can be placed on the placement station, and then the controller controls the rotation driving device 32 to start and drive the valve body to rotate. After the valve body rotates to a specified position, the image collection device starts to collect images of the valve body at the angle. Finally, the collected images are sent to the controller, which compares the images with the standard images of the valve body to determine whether the valve body is qualified. This reduces the labor intensity of workers, greatly improves the detection efficiency, and ensures the quality of the valve body.

[0041] The specific structure of the fixing device 31 in the embodiment is shown in Figure 6 The fixing device 31 includes a mounting plate 311 and a positioning column 312 rotatably arranged on the mounting plate 311, and the placement station is arranged on the positioning column 312. The rotation driving device 32 is used to drive the positioning column 312 to rotate to drive the valve body to rotate. The valve body can be accurately placed on the placement station, which facilitates the image collection device to collect the images of the valve body at different angles. The positioning column 312 is rotatably arranged on the mounting plate 311, which ensures that the rotation driving device 32 can drive the valve body to rotate. In other embodiments, the fixing device 31 can also be a clamp for the valve body.

[0042] The mounting plate 311 is provided with a plurality of positioning columns 312 in the embodiment. Each positioning column 312 is rotatably arranged on the mounting plate 311, and the valve body on each positioning column 312 is located within the image acquisition range of the image acquisition device, so that image acquisition and detection of a plurality of valve bodies are simultaneously realized, and the detection efficiency is greatly improved. In the embodiment, only one rotating drive device 32 is arranged, and all the positioning columns 312 are driven to rotate by the rotating drive device 32, so that energy is saved. In other embodiments, the rotating drive device 32 can be provided with a plurality of rotating drive devices 32, and each positioning column 312 is driven to rotate by at least one rotating drive device 32. This includes the case that each positioning column 312 is driven to rotate by a corresponding rotating drive device 32, or the case that a plurality of rotating drive devices 32 drive the same positioning column 312 to rotate.

[0043] In the embodiment, all the positioning columns 312 rotate at the same time, so that the valve bodies are all presented at a specified angle and state in the same image acquisition of the image acquisition device, which facilitates the image comparison of the controller at the angle and state. In combination with the above case, in the case that the rotating drive device 32 is only one, the embodiment also enables each positioning column 312 to be connected by the simultaneous transmission mechanism to realize self-rotation at the same time. In other embodiments, the rotating drive device 32 can be arranged according to the number of positioning columns 312, and each rotating drive device 32 drives a corresponding positioning column 312 to rotate. Finally, adjusting the speed of each rotating drive device 32 to be consistent can achieve the effect of simultaneous rotation of the positioning columns 312.

[0044] The simultaneous transmission mechanism in the embodiment is a gear transmission mechanism, and the specific structure includes a driven wheel 322 arranged below each positioning column 312 and a driving wheel 321 arranged on the rotating drive device 32. Each two adjacent driven wheels 322 are meshed with each other. The rotating drive device 32 can drive the driving wheel 321 to rotate, and the driving wheel 321 can be meshed with a driven wheel 322. In the embodiment, the rotating drive device 32 is a motor, and the driving wheel 321 is fixed on the output shaft of the motor. When the motor rotates and outputs, the driving wheel 321 is driven to rotate, and the driven wheel 322 meshed with the driving wheel 321 is also driven to rotate. At this time, all the driven wheels 322 also rotate together. In other embodiments, the simultaneous transmission mechanism can also be a chain transmission mechanism or a belt transmission mechanism, and the rotating drive device 32 can also be a swing cylinder.

[0045] The embodiment also includes a sliding device 33 for driving the rotating device to approach or move away from the fixing device 31. Since the valve body is placed on the fixing device 31, when the image acquisition of a batch of valve bodies is completed, the valve body will enter the next working process. Therefore, through the setting of the sliding device 33, the rotating device can be driven to move away from the fixing device 31 after the rotating work of the valve body is completed, at this time, the fixing device 31 can be transported to the device of the next process by the conveying device 50, and will not interfere with the rotating device. After the next fixing device 31 carrying the valve body is placed here, the sliding device 33 will drive the rotating device to approach the fixing device 31, and the driving wheel 321 and the driven wheel 322 are engaged to ensure that the subsequent rotating process can be carried out.

[0046] The fixing device 31 in the embodiment also includes a support plate 313 for supporting the valve body, and a through hole 314 for accommodating the valve body is formed on the support plate 313 corresponding to the positioning column 312. Through the setting, the valve body can be placed in the through hole 314 of the support plate 313, and will not be offset and shaken due to external collision, ensuring that the angle and state of the valve body are in the specified position when the image is acquired.

[0047] The width of the through hole 314 is less than the maximum width of the valve body. The valve body in the embodiment is a one-way valve 70, one end of which has a large diameter and the other end has a small diameter. The through hole 314 can just accommodate the end with a small diameter, that is, a part of the one-way valve 70 is placed in the through hole 314 and the other part is exposed above the through hole 314. This design can make the one-way valve 70 stably placed in the through hole 314 without offset and shaking.

[0048] The width of the through hole 314 is less than the maximum width of the valve body. The valve body in the embodiment is a one-way valve 70, one end of which has a large diameter and the other end has a small diameter. The through hole 314 can just accommodate the end with a small diameter, that is, a part of the one-way valve 70 is placed in the through hole 314 and the other part is exposed above the through hole 314. This design can make the one-way valve 70 stably placed in the through hole 314 without offset and shaking.

[0049] The embodiment further comprises a reset member arranged on the support plate 313 for resetting the support plate 313 after sliding. When the image acquisition is completed, the support plate 313 can be reset to the initial position to support and stabilize the valve body again. The reset member in the embodiment is a spring. When the support plate 313 and the positioning column 312 slide relative to each other until the support plate 313 is completely misaligned with the valve body, the spring is compressed at this time. When the image acquisition is completed, the spring expands and resets the support plate 313 to the initial position. In other embodiments, the reset member can be a rubber sleeve or other elastic material.

[0050] The embodiment further comprises a pressing device 34 for driving the support plate 313 and the positioning column 312 to slide relative to each other until the support plate 313 is completely misaligned with the valve body. In other embodiments, the action of the support plate 313 and the positioning column 312 sliding relative to each other can also be completed by manual operation.

[0051] The specific structure of the pressing device 34 in the embodiment is shown in Figure 5 The pressing device 34 in the embodiment comprises a pressing block 341 for abutting against the support plate 313, a pressing column 342 arranged corresponding to the positioning column 312, and a moving driving device 343 for driving the pressing block 341 and the pressing column 342 to approach or move away from the fixing device 31. The length of the pressing block 341 is greater than the length of the pressing column 342. When image acquisition is to be performed, the moving driving device 343 drives the pressing block 341 and the pressing column 342 to approach the fixing device 31. Since the length of the pressing block 341 is greater than the length of the pressing column 342, the pressing block 341 first abuts against the support plate 313 and is pressed downward until the support plate 313 is completely misaligned with the valve body. At the same time, the pressing column 342 above the positioning column 312 also approaches the valve body downward and abuts against the upper end of the valve body. The positioning column 312 abuts against the valve body from both ends to fix the valve body (see Figure 7 At this time, the complete image of the valve body can be acquired.

[0052] At the same time, the pressing column 342 is also rotatably arranged. When the valve body needs to be rotated during image acquisition, the pressing can be performed in the state of the pressing device 34, that is, the pressing column 342 and the positioning column 312 abut against both ends of the valve body at the same time, and the positioning column 312 is driven by the rotating driving device 32 to rotate together with the valve body and the pressing column 342, so as to ensure that the overall appearance of the valve body can be shot, and the image acquisition of the valve body in all directions can also be realized by rotating.

[0053] The air tightness detection device 40 in the embodiment is shown in Figure 8As shown, the gas filling device capable of communicating with the valve body on the placing station to introduce gas into the valve body, the controller is in communication connection with the gas filling device and the air pressure detection device 42, and the controller can control the action of the gas filling device and receive and analyze the detection data of the air pressure detection device 42. In use, the valve body can be placed on the placing station, and then the gas filling device is started to inflate the valve body until the valve body reaches a steady pressure state. At this time, the controller controls the gas filling device to stop filling gas, and the air pressure detection device 42 continuously detects the change of the pressure value in the valve body under the steady pressure state for a certain period of time. If the pressure value of the valve body changes, it means that the valve body is unqualified. Otherwise, if the pressure value of the valve body does not change, it means that the valve body is qualified. Through the above arrangement, the valve body air tightness detection can be automatically completed, the labor intensity of the workers is reduced, the detection efficiency is improved, and the quality of the valve body detection is higher.

[0054] The air pressure detection device 42 in the embodiment is a pressure switch, which is in communication connection with the controller and sends the detected information to the controller for automatic analysis and detection. In other embodiments, the air pressure detection device 42 can be a pressure gauge. The pressure gauge directly presents the detected data on the gauge after real-time detection of the pressure in the valve body. At this time, the worker can manually identify whether the pressure changes, or the pressure information of the pressure gauge can be recognized by the image acquisition device to realize automatic control.

[0055] As known from the above, the fixing device 31 in the embodiment is provided with a plurality of placing stations. The air tightness detection device 40 is provided with an air filling device and an air pressure detection device 42 corresponding to each placing station. The controller can control the air filling device and the air pressure detection device 42 to link each other to detect the valve body on each placing station. Finally, the controller can receive and analyze the detection information of all air pressure detection devices 42 and determine whether the corresponding detected valve body is qualified according to the detection information of each air pressure detection device 42. Through the above arrangement, multiple valve bodies can be detected at the same time, the detection efficiency is improved, the automatic detection can ensure the correctness of the detection, and the accuracy of the valve body detection is improved.

[0056] The corresponding embodiment in the present embodiment also includes a busbar for shunting the gas flow of the external gas generating device, and a plurality of shunt ports of the busbar are respectively connected with each of the air supply devices. In combination with the above, since a plurality of gas pressure detection devices 42 are required to be arranged to detect the valve bodies on the plurality of placement stations, the output end of the busbar is communicated with the external gas generating device, and then under the shunting effect of the busbar, the gas is respectively connected with the air supply devices through a plurality of shunt ports to achieve the air charging of each valve body. Through the arrangement of the busbar, the gas channel arrangement can be more simple, and the interference of the gas pipeline on other devices can be reduced.

[0057] In the present embodiment, an electromagnetic valve for controlling the opening and closing of the air supply device is arranged at each shunt port of the busbar, and each electromagnetic valve is in communication connection with the controller. The controller can control the opening and closing of the electromagnetic valve to correspondingly control the opening and closing of the air supply device. This arrangement is mainly applicable to the case where there are a plurality of placement stations and no valve body is placed on each placement station. At this time, the air supply device without the valve body can be controlled to stop the gas output, thereby saving the energy consumption.

[0058] The air supply device in the present embodiment includes a pneumatic connector 41 and a conduit connected with the external gas generating device, wherein the pneumatic connector 41 and the conduit are connected, and the output end of the pneumatic connector 41 is aligned with the valve body. When the external gas generating device is started, the gas can enter the valve body along the conduit and the pneumatic connector 41. In other embodiments, the air supply device can also be a gas pump or other device.

[0059] The detection system in the present embodiment also includes an air supply moving device 43 for moving the air supply device and the valve body close to or away from each other. After the valve body is placed on the placement station in the present embodiment, there is still a gap between the valve body and the air supply device. At this time, the air supply moving device 43 is started to move the air supply device close to the valve body to realize the contact between the output end of the pneumatic connector 41 and the valve body to achieve the air supply of the valve body. The specific structure of the air supply moving device 43 includes a sliding rail mechanism and a driving device for driving the sliding rail mechanism to act. The sliding rail mechanism includes a sliding rail and a sliding block slidingly arranged on the sliding rail, and the air supply device and / or the fixing device 31 are arranged on the sliding block. The driving device is used to drive the sliding block to slide along the sliding rail to realize the mutual approach or separation of the air supply device and the valve body. By adopting the sliding mode of the sliding rail, the air supply device can be guided, and the output end of the pneumatic connector 41 can be accurately connected to the valve body. In addition, the air supply moving device 43 in the present embodiment can drive the air supply device to move or drive the fixing device 31 to move. In other embodiments, in addition to the linear sliding rail and the arc-shaped sliding rail, a connecting rod mechanism and a driving device can also be used to realize the arc-shaped swinging mode.

[0060] The embodiment includes a distribution device 10 for orderly conveying the valve bodies to the distribution station, referring to Figure 2 As shown, it includes a distribution channel 11 and a distribution drive device 12 for driving the valve bodies to move along the distribution channel 11. In this embodiment, a vibrating disc is used as the distribution drive device 12, wherein the output end of the vibrating disc is connected with the head end of the distribution channel 11, and the valve bodies are orderly conveyed one by one along the track in the hopper of the vibrating disc and gradually upward, and finally enter the distribution channel 11. This conveying mode can ensure that the valve bodies are conveyed more orderly, and can also directly combine with the setting that the distribution channel 11 can pass through only one valve body in the above embodiment, so that the valve bodies can be directly docked on the distribution channel 11 after being conveyed one by one from the track, and the transition is more convenient. In other embodiments, a conveyor belt can also be used as the distribution drive device 12.

[0061] The distribution channel 11 is provided with a plurality of through grooves which are arranged side by side, the width of the through grooves is matched with the width of the valve bodies, and the number of positioning columns 312 on the taking device 21 and the fixing device 31 is consistent with and corresponds to the number of the through grooves. In this way, the number of each time carrying detection becomes multiple, the number of each time conveying and detecting is increased, and the overall work efficiency is improved.

[0062] The embodiment also includes a material supplementing device 13 for supplementing the valve bodies to the hopper of the vibrating disc, which is automatically supplemented by the automatic device when the valve bodies in the hopper are reduced. The material supplementing device 13 is arranged directly above the hopper of the vibrating disc, and the specific structure includes a hopper, a baffle for blocking the opening below the hopper, and an opening and closing drive device for controlling the opening and closing of the baffle. In the conventional state, the valve bodies are placed in the hopper, at this time the baffle can block the opening below the hopper to limit the valve bodies from flowing out of the hopper, and when the valve bodies in the vibrating disc are insufficient, the opening and closing drive device can be opened to open the baffle, and at this time the valve bodies can directly fall into the hopper below from the hopper.
