Description

Technical Field

[0001] The present invention relates to the technical field of precision filter detection, and particularly relates to a backwater detection system based on the air film of a precision filter. Background Art

[0002] At present, precision filters are widely used in the medical treatment process. A precision filter is composed of an upper shell, an air film, a lower shell, and a liquid film. The air film needs to be welded to the upper shell through an ultrasonic welding process.

[0003] In the prior art, the quality of the air film is usually detected by CCD vision detection technology. In view of the characteristic that the air film is breathable but not water-permeable, the CCD vision detection technology cannot accurately detect the quality of the air film and the welding quality between the air film and the upper shell. Therefore, manual inspection is usually also used to detect the quality of the air film and the welding quality between the air film and the upper shell. However, manual inspection is prone to attaching germs to the air film, resulting in unqualified product hygiene requirements. Moreover, manual inspection is also easily affected by personnel differences, resulting in low detection qualification rates and huge consumption of human resources.

[0004] Therefore, the existing detection methods for the quality of the air film and the welding quality between the air film and the upper shell have problems of low detection qualification rates and low detection efficiency. Summary of the Invention

[0020] The control device is used to control the motion states of the feeding device, the transfer device, the detection device, the drying device, and the blanking device.

[0021] Among them, the control device includes a display panel and a plurality of control buttons.

[0055] The precision filter is composed of an upper shell 700, an air film 710, a lower shell, and a liquid film. For details, please refer to Figure 12 As shown, it is the upper shell 700 in the precision filter. The air film 710 is welded inside the upper shell 700. Since the other components of the precision filter belong to the prior art, only the air film 710 and the upper shell 700 are shown in Figure 12 this figure.

[0056] Embodiment

[0057] Please refer to Figures 1 to 11 shown in the figure, which is a backwater detection system based on the air film of a precision filter in an embodiment of the present invention, including a transfer device 100, and a loading device 200 and a detection device 300 sequentially distributed along the transfer trajectory of the transfer device 100.

[0058] The transfer device 100 is used to transfer a plurality of materials to be detected placed in the loading device 200 to the detection device 300 for quality detection. The materials are the upper shell 700 and the air film 710 welded inside the upper shell 700;

[0059] The transfer device 100 includes an intermittent driver 110 and a plurality of material fixtures 120. The intermittent driver 110 is used to drive the material fixtures 120 to perform intermittent movement. Among them, each material fixture 120 is provided with a plurality of accommodating cavities 130 for accommodating materials;

[0060] The detection device 300 includes a hydraulic execution component 310, a plurality of lifting spray heads 320, and a plurality of image acquirers 330;

[0061] Each lifting spray head 320 and each image acquirer 330 are respectively used to face opposite sides of each accommodating cavity 130. The hydraulic execution component 310 is used to fix the material fixture 120 within the lifting trajectory of the lifting spray head 320, so that when the lifting spray head 320 rises, the lifting spray head 320 is hermetically connected to the material;

[0062] Among them, the lifting spray head 320 is used to inject the detection liquid into the material, and each image acquirer 330 is respectively used to obtain the image information of the detection liquid in each material, so as to judge the quality of the air film 710 in each material and the welding quality of each upper shell 700 and the air film 710 through the corresponding graphic information.

[0063] It should be noted that in actual situations, the air film 710 has the characteristics of being breathable but not permeable to water. When the air film 710 is welded to the upper shell 700, both the quality of the air film 710 itself and the welding quality between the air film 710 and the upper shell 700 will affect the use effect of the precision filter.

[0064] In this embodiment, to facilitate the detection of the quality of the air film 710 and the welding quality between the air film 710 and the upper shell 700, first, the feeding device 200 is used to transport multiple materials into the material fixture 120 of the transfer device 100. The intermittent driver 110 of the transfer device 100 can intermittently transport the material fixture 120, so that the material fixture 120 with materials can face the detection device 300. The hydraulic execution component 310 of the detection device 300 is used to fix the material fixture 120, so that when the lifting nozzle 320 rises to the bottom of the material, the lifting nozzle 320 can be hermetically connected to the bottom of the material. Finally, the detection liquid is injected into the interior of the material through the lifting nozzle 320. Due to the characteristics of the air film 710 in the material being breathable but not permeable to water, when there are problems with the quality of the air film 710 itself in the material and the welding quality between the air film 710 and the upper shell 700, bubbles will be generated inside the upper shell 700. The image acquisition device 330 is used to acquire the image information inside the upper shell 700. When there are bubbles in the image information, it is determined that there are problems with the quality of the air film 710 in the corresponding material and the welding quality between the air film 710 and the upper shell 700. Through this setting, the situation of misjudgment during manual detection can be effectively avoided, and the technical problems of low detection qualification rate and low detection efficiency in the existing technology are solved.

[0065] Please refer to Figure 4 and Figure 5 As shown, the feeding device 200 includes at least two groups of vibrating bowls 210 and at least two groups of feeding grippers 220. Each group of vibrating bowls 210 includes a plurality of spaced transmission channels 211. Each group of feeding grippers 220 includes a plurality of feeding grippers 220. Each feeding gripper 220 is respectively arranged opposite to each transmission channel 211. Among them, each transmission channel 211 is used to transport the material to the feeding position of each feeding gripper 220, and the feeding gripper 220 clamps the material into the corresponding accommodating cavity 130. It should be noted that the vibrating bowl 210 can generate vibration, so that a plurality of materials can vibrate and be transported along the direction of the transmission channel 211, and the corresponding materials are clamped into the corresponding accommodating cavity 130 by the feeding gripper 220. The vibrating bowl 210 belongs to the conventional prior art in this field, so no special description will be made here.

[0066] In some actual situations, the loading device 200 may further include a loading bracket. The loading gripper 220 may adopt a jaw with a gripping function in the prior art. The loading gripper 220 may be slidably connected to the loading bracket, so that after the loading gripper 220 grips the material, it can be moved into the corresponding receiving cavity 130.

[0067] To further understand this case, in this embodiment, there may be four material fixtures 120, and each material fixture 120 has 12 receiving cavities 130. That is to say, when the loading device 200 first transports a plurality of materials to the first material fixture 120, 12 materials can be transported into the first material fixture 120 at one time. Subsequently, the intermittent driver 110 performs the first drive, so that the first material fixture 120 can face the detection device 300 for detection. At this time, the second material fixture 120 will face the loading device 200. After the materials in the first material fixture 120 are detected, the intermittent driver 110 performs the second drive, so that the first material fixture 120 can move to the side away from the detection device 300. At this time, the second material fixture 120 will face the detection device 300 for detection. By using this method, multiple materials can be synchronously detected, further improving the detection efficiency.

[0068] It should be noted that when there are 12 receiving cavities 130, the lifting nozzle 320 and the image acquirer 330 also have 12, and the receiving cavity 130, the lifting nozzle 320, and the image acquirer 330 are arranged in one-to-one correspondence, and the image acquirer 330 may adopt a high-definition camera in the prior art.

[0069] Specifically, please refer to Figure 2 and Figure 3 As shown, the four material fixtures 120 can move in a circular trajectory. In this embodiment, the transfer device 100 further includes a turntable 140. The turntable 140 is connected to the output end of the intermittent driver 110. Among them, a plurality of material fixtures 120 are circumferentially spaced on the turntable 140 with the center of the turntable 140 as the origin. It should be noted that the intermittent driver 110 in this embodiment may adopt a servo motor, and the servo motor is used to drive the turntable 140 to rotate intermittently, so that the plurality of material fixtures 120 on the turntable 140 can rotate synchronously and intermittently.

[0070] In addition, it should be noted that the hydraulic actuator assembly 310 shown in this embodiment may be composed of a cylinder and a pressing plate. There are a plurality of shooting through holes on the pressing plate, and the shooting through holes can ensure the normal shooting of the image acquirer. The cylinder can be used to drive the pressing plate to lift, so that the pressing plate fixes the material fixture 120 on the turntable 140.

[0071] In some preferred embodiments, when the quality inspection of the material is qualified, to avoid contamination of the material caused by the detection liquid remaining inside the material, the backwater detection system further includes a drying device 400 for cleaning the detection liquid inside the material.

[0072] Among them, the drying device 400 includes a plurality of upper air nozzles 410 and a plurality of lower air nozzles 420.

[0073] Each upper air nozzle 410 and each lower air nozzle 420 are respectively used to face opposite sides of each accommodating cavity 130, so that the upper air nozzle 410 and the lower air nozzle 420 blow dry opposite sides of the material respectively.

[0074] Specifically, the drying device 400 is arranged after the detection device 300. That is to say, when the material detection is completed, there will be materials with qualified detection and materials with unqualified detection. When the material detection is qualified, there will be detection liquid remaining at the bottom of the air film 710 in the material. The lower air nozzle 420 can be used to blow dry the detection liquid to ensure the dryness at the bottom of the air film 710.

[0075] When the material detection is unqualified, the quality of the air film 710 itself and the welding quality between the air film 710 and the upper shell 700 will both cause the detection liquid to penetrate to the top of the air film 710, resulting in detection liquid remaining at both the bottom and the top of the air film 710. By blowing air to the top and bottom of the air film 710 respectively through the upper air nozzle 410 and the lower air nozzle 420, and during the blowing process, the inside of the upper shell 700 can also be dried, which can ensure the dryness of the inside of the upper shell 700, as well as the dryness of the top and bottom of the air film 710.

[0076] Furthermore, to facilitate the centralized treatment of the detection liquid, in some preferred embodiments, the drying device 400 further includes an air nozzle pressing component 430 and a drying bracket 440 with a diversion groove 441. A plurality of upper air nozzles 410 are all connected to the air nozzle pressing component 430. The air nozzle pressing component 430 is used to synchronously drive a plurality of upper air nozzles 410 to connect with the end face of the corresponding material. The diversion groove 441 is used to collect the detection liquid and conduct diversion. That is to say, the air nozzle pressing component 430 can be used to drive a plurality of upper air nozzles 410 to contact the top of the corresponding upper shell 700, so that the upper air nozzle 410 can accurately blow dry the top of the air film 710 and the upper half inside of the upper shell 700.

[0077] It should be noted that in this embodiment, the air nozzle pressing component 430 can be composed of a cylinder and a connecting plate. A plurality of upper air nozzles 410 can be arranged on the connecting plate, and the cylinder can drive the connecting plate to move up and down.

[0078] Please refer to Figure 10As shown in the figure, to prevent the detection liquid from splashing to other parts during air blowing, the middle part of the drying bracket 440 is provided with a protective frame. The lower air nozzle 420 is arranged inside the protective frame, and the upper air nozzle 410 is arranged above the protective frame. By using the protective frame, when the lower air nozzle 420 blows air, the detection liquid at the bottom of the air film 710 will splash onto the inner wall of the protective frame and finally fall into the diversion groove 441 for collection. At the same time, considering that the upper air nozzle 410 is lifted and lowered by the air nozzle pressing component 430, the upper air nozzle 410 can contact the upper end surface of the upper shell 700. Then, a closed space is formed between the edge of the upper air nozzle 410 and the edge of the upper end surface of the upper shell 700. Then, the upper air nozzle 410 will directly perform the drying process, and the detection liquid at the top of the air film 710 will not splash.

[0079] It should be noted that in this example, the detection liquid can be pure water.

[0080] In addition, to facilitate the feeding of qualified and unqualified materials after detection, in this example, the anti-water detection system further includes a feeding device 500, and the feeding device 500 is used to sort the qualified materials and unqualified materials by quality;

[0081] The feeding device 500 includes a feeding bracket 510, a plurality of feeding claws 520 slidably connected to the feeding bracket 510, and at least two material collection bins 530 arranged below the feeding bracket 510;

[0082] Each feeding claw 520 is used to be arranged opposite to each accommodating cavity 130, and the feeding claw 520 is used to sort the materials into the corresponding material collection bins 530 for collection according to the quality of the materials;

[0083] Among them, at least one material collection bin 530 is used to collect qualified materials, and at least one other material collection bin 530 is used to collect unqualified materials.

[0084] Specifically, in this example, there can be two material collection bins 530. The first material collection bin 530 is used to collect qualified materials, and the second material collection bin 530 is used to collect unqualified materials. The first material collection bin 530 can have an inclined feeding channel, and the feeding channel is used to facilitate the transmission of qualified materials to the outside for subsequent processing. The second material collection bin 530 can be a box with an opening to facilitate the treatment of unqualified materials in the later stage.

[0085] It should be noted that the feeding claw 520 can adopt a claw with a clamping function in the prior art.

[0086] Furthermore, to realize the intelligent management of the entire system, the anti-water detection system further includes a control device 600;

[0087] The control device 600 controls the motion states of the feeding device 200, the transfer device 100, the detection device 300, the air-drying device 400, and the discharging device 500 respectively;

[0088] Among them, the control device 600 includes a display panel 610 and a plurality of control buttons 620;

[0089] The display panel 610 is used to display a plurality of image information, and the control buttons 620 are used to control the movement of the discharging jaws 520 towards the corresponding material collection bins 530.

[0090] The display panel 610 can be used to separately display a plurality of image information. That is to say, when there are 12 image acquirers 330, 12 image information will be correspondingly acquired, and the 12 graphic information will be displayed on the display panel 610, that is, 12 image screens, so as to facilitate manual inspection of the image screens in each material. When there are bubbles in one of the image screens, the corresponding control button is pressed. At this time, the corresponding discharging jaws 520 will grab the unqualified upper shells 700 and move them into the corresponding material collection bins 530. When the inspection is qualified, there is no need to press the control buttons 620. It should be noted that each control button is respectively used to control the movement state of each discharging jaw 520.

[0091] In addition, for the convenience of inspecting materials at night, in some other preferred embodiments, the detection device 300 further includes a plurality of light source components 350, and each light source component 350 is respectively arranged at the shooting end of each image acquirer 330 for emitting light;

[0092] Among them, the control device 600 further includes a plurality of light source adjustment components 630. Each light source component 350 is connected to each light source adjustment component 630, and the light source adjustment component 630 is used to adjust the brightness of the light source component 350.

[0093] It should be noted that an image splitter can be arranged in the detection device 300 to split the image information acquired by the plurality of image acquirers 330.

[0094] The light source component 350 can be an industrial light source generator. The light source component 350 can emit bright light, and at the same time, the brightness of the light source component 350 can be adjusted through the corresponding light source adjustment component 630, so that the light source can be controlled within a reasonable brightness range, further ensuring the clarity of the image screen.

[0095] In addition, due to the unreliability of manual monitoring of image screens, in this embodiment, the detection device 300 further includes a pressure barrel 340 for containing the detection liquid and for identifying pressure data. The pressure barrel 340 is connected to the control device 600 and a plurality of lifting nozzles 320.

[0096] When each lifting nozzle 320 injects the detection liquid into each material, the pressure data in each material is detected according to the pressure barrel 340, and based on the pressure data, the control device 600 controls the corresponding blanking jaw 520 to grab the corresponding material and move towards the corresponding material collection bin 530.

[0097] That is to say, the pressure barrel 340 can be used to identify the pressure data of the detection liquid in each material. When the pressure data does not meet the pressure data of qualified products, it is determined that the quality of the air film 710 in the material and the welding quality between the air film 710 and the upper shell 700 are unqualified. Through the double detection of pressure identification and image information, the accuracy of detection can be guaranteed. Especially when there are small gaps in the welding between the air film 710 and the upper shell 700 and slight bubbles appear, and the slight bubbles are not easily detected by the staff, the unqualified quality of the material can be detected by using the pressure data, further ensuring the qualification rate of detection.

[0098] In summary, a water backflow detection system based on the air film of a precision filter provided by an embodiment of the present invention, through the settings of the transfer device 100, the feeding device 200, and the detection device 300, when detecting the quality of materials with an air film 710 and an upper shell 700, first, the feeding device 200 transports a plurality of materials into the material fixture 120 of the transfer device 100. The intermittent driver 110 of the transfer device 100 can intermittently transport the material fixture 120, so that the material fixture 120 with materials can face the detection device 300. The hydraulic execution component 310 of the detection device 300 fixes the material fixture 120, so that when the lifting nozzle 320 rises to the bottom of the material, the lifting nozzle 320 can be hermetically connected to the bottom of the material. Finally, the detection liquid is injected into the interior of the material through the lifting nozzle 320. By virtue of the property that the air film 710 in the material is permeable to air but impermeable to water, when there are problems with the quality of the air film 710 itself and the welding quality between the air film 710 and the upper shell 700 in the material, bubbles will be generated inside the upper shell 700. The image acquirer 330 acquires the image information inside the upper shell 700. When there are bubbles in the image information, it is determined that there are problems with the quality of the air film 710 and the welding quality between the air film 710 and the upper shell 700 in the corresponding material. Through this setting, the situation of misjudgment during manual detection can be effectively avoided, and the technical problems of low detection qualification rate and low detection efficiency in the prior art can be solved.
