Description

Technical Field

[0001] This application relates to the technical field of nursing pads, and in particular to the technology for preparing high-absorbency embossed nursing pads. Background Technology

[0002] Nursing pads are a common hygiene product, often used by people with limited mobility, such as postpartum or post-operative individuals, to absorb excreted fluids. Therefore, during the manufacturing process, nursing pads need to be packaged in sealed bags to prevent external moisture and impurities from entering and causing the pads to become damp and moldy. However, current production processes lack inspection of the sealed bags. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a high-absorbency embossed nursing pad preparation technology, which has the advantage of being able to inspect the sealed bag.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] The high-absorbency embossed nursing pad manufacturing technology includes an inspection box, a negative pressure device, and a detection system. The inspection box is sealed and contains a support device, which includes a support plate and multiple electric suction cups mounted on the support plate. The negative pressure device is connected to the inspection box and is used to create a negative pressure within the inspection box. The electric suction cups are used to pick up the packaging bags placed on the support plate. The detection system includes a data acquisition module, a notification module, and a comparison module. The data acquisition module acquires images of the packaging bags under negative pressure and sends the acquired images to the comparison module. After receiving the images from the data acquisition module, the comparison module makes a judgment. If the images differ from the standard images, it sends a non-compliance signal to the notification module. Upon receiving the non-compliance signal, the notification module issues a non-compliance notification.

[0006] By adopting the above technical solution, the packaging bag is fixed during use, and negative pressure is applied inside the inspection box. When the packaging bag is damaged, it will not expand under negative pressure. Therefore, the packaging bag is image captured, which can determine whether the packaging bag is damaged. This allows for the inspection of sealed bags and reduces the probability of damaged packaging entering the market.

[0007] In a preferred embodiment, the present application may be further configured such that: the support device includes a driving member for driving the support plate to rotate; the upper and lower surfaces of the support plate are provided with electric suction cups; the electric suction cups on the upper surface are connected to a rotary joint through a pipe; and the electric suction cups on the lower surface are connected to a rotary joint through a pipe.

[0008] By adopting the above technical solution, the product is rotated so that the adsorbed side faces downwards by rotating the support plate, and then the adsorption on the product is released, thereby achieving unloading. There is also an electric suction cup on the other side, so loading can be carried out at the same time as unloading, thereby improving inspection efficiency.

[0009] In a preferred embodiment, the present application may be further configured such that: the detection system further includes a control module; after receiving a non-conforming signal, the notification module sends a rejection signal to the control module; after receiving the rejection signal, the control module queries the number of the electric suction cup corresponding to the non-conforming product in the comparison module, controls the electric suction cup corresponding to the number to maintain a suction state for a duration of T, and the control module controls the drive component to drive the support plate to flip.

[0010] By adopting the above technical solution, which involves maintaining the adsorption of unqualified products after flipping, allowing qualified products to fall off after a time T, and then canceling the adsorption of unqualified products to allow them to fall off, unqualified products can be effectively removed.

[0011] In a preferred embodiment, the present application can be further configured such that the detection system also includes a statistics module, the control module inputs the queried electric suction cup number into the statistics module, and if the number of times a certain electric suction cup number appears within a unit time exceeds a preset value, the statistics module sends an abnormal signal to the notification module, and the notification module issues an abnormal notification.

[0012] By adopting the above technical solution, if the product picked up by the electric suction cup with the specified number repeatedly has problems within a unit of time, it indicates that there may be a problem during the transportation process, and therefore a notification is issued.

[0013] In a preferred embodiment, the present application may be further configured such that: the detection system further includes a testing module; after receiving an abnormal signal, the notification module sends a test signal to the testing module; after receiving the test signal, the testing module controls the conveying device to transport the qualified product to the electric suction cup corresponding to the number; after detection, if the product is unqualified, the comparison module sends a test failure signal to the testing module; after receiving the test failure signal, the testing module sends a conveying device abnormality signal to the notification module.

[0014] By adopting the above technical solution, when the conveying device may malfunction, a test is conducted, and qualified products are transferred to the electric suction cup corresponding to the number via the conveying device. If the test result is unqualified, it indicates that there is damage during the conveying process.

[0015] In a preferred embodiment, this application can be further configured such that: the statistics module counts the number of times the electric suction cups are received; if the number of times exceeds a preset value within a unit of time, a sealing abnormality signal is sent to the notification module, and the notification module notifies the user of the sealing abnormality.

[0016] By adopting the above technical solution, if multiple electric suction cup numbers are received within a unit of time, it indicates that there are multiple unqualified products within that unit of time, and therefore the sealing process may be faulty, so a notification is required.

[0017] In a preferred embodiment, the present application may be further configured such that: the detection system further includes a detection module, wherein there are multiple detection modules and each corresponds to an electric suction cup, for detecting the packaging bag being sucked up by the electric suction cup; when the control module controls the electric suction cup to maintain the suction state for a duration of T, it queries the status of the detection module corresponding to the number; if the status is negative, the control module sends the number to the notification module.

[0018] If no product is detected during a suction period of time T using the above technical solution, it indicates that the electric suction cup has failed and needs to be repaired.

[0019] In a preferred embodiment, this application can be further configured such that: the control module controls the conveying device to convey the product to the electric suction cup; when the control module controls the electric suction cup to maintain a suction state for a duration of T, and the corresponding detection module detects a negative state, the control device does not place the product at the corresponding electric suction cup.

[0020] By adopting the above technical solution, when the electric suction cup fails, the product will not be placed at the electric suction cup when the control conveyor is handling the product.

[0021] In a preferred embodiment, the present application can be further configured such that the detection system also includes a re-inspection module. After the control module detects that the status is negative, it sends a re-inspection signal to the re-inspection module. After receiving the re-inspection signal, the re-inspection module transfers the batch of products.

[0022] By adopting the above technical solution, and considering that when the electric suction cup fails, indicating that the unqualified products also fall off, the batch of products is re-inspected. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 This application discloses a high-absorbency embossed nursing pad preparation technology, comprising an inspection box 1, a negative pressure device, and a detection system. The inspection box 1 is sealed. The negative pressure device, which can be a fan, is connected to the inspection box 1 to create negative pressure in the inspection box 1. The inspection box 1 contains a support device, which includes a support frame 11, a support plate 12, and a guide plate 14. The support plate 12 and the support frame 11 are rotatably connected. The guide plate 14 is located below the support plate 12 and is rotatably connected to the support frame 11. Both sides of the guide plate 14 can be provided with receiving baskets or closable guide pipes, which are connected to the outside of the inspection box 1. The support frame 11 is equipped with a driving component for rotating the support plate 12, and a power source for rotating the guide plate 14. In this embodiment, both the driving component and the power source can be electric motors.

[0028] Multiple electric suction cups are provided on both the upper and lower surfaces of the support plate 12. The electric suction cups are numbered. The electric suction cups on the upper surface are connected to rotary joint 13 via pipes. Rotary joint 13 is connected to an air source via pipes. The electric suction cups on the lower surface are connected to rotary joint 2 via pipes. Rotary joint 2 is connected to an air source via pipes.

[0029] The detection system includes a data acquisition module 2, a notification module 4, a comparison module 3, a control module 7, a statistics module 8, a testing module 5, a detection module 6, and a re-inspection module 9. The data acquisition module 2 is used to acquire images of the packaging bag under negative pressure and send the acquired images to the comparison module 3. After receiving the images sent by the data acquisition module 2, the comparison module 3 makes a judgment. If the images are different from the standard images, it sends a non-compliance signal to the notification module 4. After receiving the non-compliance signal, the notification module 4 issues a non-compliance notification.

[0030] After receiving the non-conforming signal, the notification module 4 sends a rejection signal to the control module 7. After receiving the rejection signal, the control module 7 queries the number of the electric suction cup corresponding to the non-conforming product in the comparison module 3, controls the electric suction cup corresponding to the number to maintain the suction state for a duration of T, and controls the drive component to rotate the support plate 12.

[0031] In use, the conveying device, such as a robotic arm with multiple electric suction cups (in this embodiment, the number of electric suction cups on the robotic arm is half the number of electric suction cups on the support plate 12), picks up and conveys the product to the electric suction cups on the support plate 12. When the support plate 12 is full of products, the negative pressure device is activated, creating a negative pressure inside the inspection box 1. The electric suction cups then work to pick up the product. After a period of time, the acquisition module 2 acquires images of the product and sends the acquired images to the comparison module 3 for comparison. If the image differs from the standard value, a non-compliance signal is sent to the notification module 4. After receiving a non-conforming signal, the knowledge module 4 sends a rejection signal to the control module 7. Upon receiving the rejection signal, the control module 7 queries the number of the electric suction cup corresponding to the non-conforming product in the comparison module 3, controls the electric suction cup corresponding to that number to maintain a suction state for a duration of T, and controls the support plate 12 to flip and the guide plate 14 to tilt. Since other electric suction cups are not working, the qualified products will fall onto the guide plate 14 and be guided out by the guide plate 14. After all the qualified products have fallen, the guide plate 14 is controlled to tilt in the opposite direction, so that the non-conforming products enter another area, thereby realizing the rejection of the non-conforming products.

[0032] Control module 7 inputs the queried electric suction cup number into statistics module 8. If the number of times a certain electric suction cup number appears exceeds a preset value within a unit of time, statistics module 8 sends an abnormal signal to notification module 4, which then issues an abnormal notification. Upon receiving the abnormal signal, notification module 4 sends a test signal to test module 5. Upon receiving the test signal, test module 5 controls the conveyor to transport qualified products to the electric suction cup corresponding to the number. After inspection, if the product fails, comparison module 3 sends a test failure signal to test module 5. Upon receiving the test failure signal, test module 5 sends a conveyor abnormality signal to notification module 4.

[0033] The statistics module 8 counts the number of times the electric suction cups are received. If the number of times exceeds a preset value within a unit of time, a sealing abnormality signal is sent to the notification module 4, and the notification module 4 notifies the sealing abnormality.

[0034] When a packaged bag picked up by a certain electric suction cup is damaged, the control module 7 transmits the number of the electric suction cup to the statistics module 8. The statistics module 8 counts the number of times each electric suction cup number appears within a unit of time. When the number of times a certain number appears exceeds a preset value, a test is performed by the test module 5. The test module 5 controls the conveying device to clamp the qualified product and convey it to the support plate 12. Then, an inspection is performed. If the product at the electric suction cup corresponding to that number is still unqualified, it indicates that the product was damaged during the conveying process.

[0035] The statistics module 8 also counts the sum of the number of times each electric suction cup appears within a unit of time. If the number of times within a unit of time is greater than the preset value, it indicates that the sealing process has failed.

[0036] Multiple detection modules 6 are configured, each corresponding to a different electric suction cup. In this embodiment, these can be distance sensors used to detect the packaging bags being picked up by the electric suction cups. When the control module 7 controls the electric suction cups to maintain a suction state for a duration of T, it queries the status of the detection module 6 corresponding to that number. If the status is negative, the control module 7 sends the number to the notification module 4. Subsequently, when the control module 7 controls the conveyor device to place products, no product is placed at the position corresponding to that number. After the control module 7 detects a negative status, it sends a re-inspection signal to the re-inspection module 9. Upon receiving the re-inspection signal, the re-inspection module 9 transfers the batch of products.

[0037] If the electric suction cup maintains a suction state for a duration of T, it indicates the presence of defective products. If the detection module 6 cannot detect them, it indicates that the electric suction cup has failed to pick up the products. Therefore, the products that fall in this batch need to be transferred and re-inspected under the action of the guide plate 14, and all the qualified products in this batch need to be transferred.

[0038] The implementation principle of this embodiment is as follows: during the production process, by inspecting the packaging bags containing nursing pads and removing unqualified products, the probability of unqualified products entering the market can be effectively reduced.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
