[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] refer to Figure 1 The present application discloses an online detection method for the sealing performance of a contact lens packaging box, comprising the following steps: S1. Randomly select a packaging box for transmission, and set a first predetermined position and a second predetermined position in sequence during the transmission.

[0024] The above-mentioned random extraction of packaging boxes can be done manually on the production line or by using equipment to extract from the production line. It should be explained that the method of extracting on the production line by using equipment is a pseudo-random method with a certain regularity, but it does not affect the subsequent test results.

[0025] S2. When the packaging box is transferred to the first predetermined position, it is positioned for the first time so that the packaging box stops transferring and remains at the first predetermined position.

[0026] When the packaging box reaches the first predetermined position, the transport may be stopped to keep the packaging box at the first predetermined position.

[0027] S3, taking a sealing sheet, applying the sealing sheet to the packaging box at the first predetermined position, and pasting the sealing sheet to the aluminum foil.

[0028] The sealing sheet can be pasted manually or automatically by equipment, thereby reducing manual participation and reducing labor costs. After the sealing sheet is pasted with the aluminum foil, the sealing performance can be improved and the test error can be reduced in the subsequent steps.

[0029] S4, continue to transport, transport the packaging box with the sealing sheet to the second predetermined position, and position it for the second time, so that the transportation is suspended and it remains at the second predetermined position.

[0030] S5, running the detection module, aligning the probe of the detection module with the packaging box at the second predetermined position, and the probe passes through the sealing sheet and the aluminum foil in sequence, and extends into the closed cavity to inflate until the sealing of the closed cavity fails.

[0031] Step S4 and step S5 are coordinated to insert the probe into the interior of the packaging box to apply pressure and detect the sealing performance of the packaging box.

[0032] S6. During the inflation process, the detection module records the packaging box at the second predetermined position, obtains the real-time pressure value, and makes a sealing judgment. At the same time, the camera module is used to record the sealing failure point.

[0033] Specifically, the detection module is preset with a rated air pressure value. After the probe penetrates the packaging box, the packaging box is slowly pressurized until the pressure inside the packaging box reaches the rated air pressure value and then the pressurization stops. If the pressure inside the packaging box decreases during the packaging process or fails to reach the rated air pressure value within a limited time, it is determined that the sealing of the closed cavity has failed.

[0034] While pressurizing the packaging box, the camera module starts to record the aluminum foil on the packaging box to observe the sealing failure point.

[0035] S7. According to the sealing judgment result in step S6, if it is judged to be qualified, step S1 is continued to be re-executed; if it is judged to be unqualified, an alarm is given and the detection is stopped.

[0036] When the above judgment result is unqualified, it means that the packaging box is an unqualified defective product. When the alarm is issued, the production line can be stopped synchronously to facilitate equipment maintenance on the production line and rapid screening of defective products.

[0037] refer to Figure 2 and Figure 3 In one embodiment of the present application, a detection device is also disclosed for implementing the above-mentioned online detection method for sealing performance, including: a transmission positioning module 1 and a sealing module 2, a detection module, and a camera module 4 arranged along the transmission direction of the transmission positioning module 1.

[0038] The transmission positioning module 1 includes a conveying mechanism 11 for conveying the packaging box, the conveying mechanism 11 has a head end and a tail end opposite to each other, and the packaging box is conveyed from the head end to the tail end of the conveying mechanism 11. A positioning component is provided on the transmission path of the packaging box to block the passing packaging box and restrict its transmission to the downstream.

[0039] There are at least two groups of positioning components, one group of positioning components cooperates with the conveying mechanism 11 to form a first predetermined position, and the remaining group of positioning components cooperates with the conveying mechanism 11 to form a second predetermined position. It should be noted that in the packaging box conveying direction, the second predetermined position is located downstream of the first predetermined position.

[0040] The sealing module 2 is set corresponding to the first predetermined position and is used to stick the sealing sheet on the packaging box. The detection module 3 and the camera module 4 are set corresponding to the second predetermined position. The detection module 3 is used to inject gas into the closed cavity to obtain the real-time pressure value; the camera module 4 is used to collect the image of the closed cavity at the moment of seal failure and record the seal failure point.

[0041] To facilitate the recycling of the tested packaging boxes, refer to Figure 1 In some embodiments, a sample storage box 13 is provided, and the sample storage box 13 is located at the end of the transmission direction of the conveying mechanism 11. When the test is completed, the packaging box will fall into the sample storage box 13 as the conveying mechanism 11 runs.

[0042] Furthermore, in order to ensure uniformity of the sealing sheet pasting position, in some embodiments, the packaging box on the conveying mechanism 11 is further positioned. Figure 3 As shown, a first guide mechanism 111 and a second guide mechanism 112 are respectively provided on both sides of the conveying mechanism 11. The first guide mechanism 111 and the second guide mechanism 112 are arranged in parallel along the transmission direction of the conveying mechanism 11, and respectively act on the left and right sides of the packaging box conveyed on the conveying mechanism 11 to prevent the packaging box from being offset perpendicular to the transmission direction during the transmission process.

[0043] refer to Figure 6In some embodiments, the positioning assembly includes a vertically arranged telescopic cylinder 121 and a block 122 connected to the piston rod of the telescopic cylinder 121. The telescopic cylinder 121 is arranged on one side of the conveying mechanism 11, and the block 122 is connected to the piston rod of the telescopic cylinder 121, and partially extends toward one side of the conveying mechanism 11 to form a shielding component acting on the packaging box. When the piston rod is in a retracted state, the shielding component on the block 122 blocks the transmission path of the packaging box, limiting the transmission of the packaging box downstream. When the piston rod is in an extended state, the shielding component on the block 122 leaves the transmission path of the packaging box, eliminating interference with the transmission of the packaging box.

[0044] Further, combined with Figure 3 and Figure 6 The positioning components are distinguished according to their respective locations in the transmission positioning module 1, and can be divided into a first positioning component 123, a second positioning component 124, and a third positioning component 125.

[0045] The first positioning component 123 is arranged corresponding to the first predetermined position, and is used to position and limit the packaging box when the sealing module 2 is working. The second positioning component 124 is arranged corresponding to the second predetermined position, and is used to position and limit the packaging box when the detection module 3 is working. The third positioning component 125 is arranged upstream of the first predetermined position corresponding to the transmission direction of the packaging box, and when the sealing module 2 is working, it limits the packaging box from continuing to be transmitted into the first predetermined position.

[0046] In some embodiments, through the cooperation of the first positioning component 123, the second positioning component 124, and the third positioning component 125, the conveying mechanism 11 can always keep moving, so that when one of the sealing module 2 or the detection module 3 is working, the conveying mechanism 11 can still transfer and load materials to the remaining one, thereby shortening the downtime waiting time and improving work efficiency.

[0047] In other embodiments, the conveying mechanism 11 may stop working when the packaging box reaches the first predetermined position or the second predetermined position.

[0048] refer to Figure 4 and Figure 5 In some embodiments, the sealing module 2 includes a feeding assembly 21 for feeding the sealing sheet and a movable sealing sheet grabbing assembly 22. The sealing sheet grabbing assembly 22 is movable between the conveying mechanism 11 and the feeding assembly 21, and is used to grab the sealing sheet from the feeding assembly 21 and paste it to the packaging box at the first predetermined position.

[0049] The feeding component 21 may be a flyer component, which can unwind and feed the coiled material with the sealing sheet adhered thereto, thereby making the transmission of the sealing sheet more convenient.

[0050] For further reference, Figure 5 The sealing sheet grabbing assembly 22 includes a lifting mechanism 221 , a translation mechanism 222 , and a grabbing mechanism 223 .

[0051] The grabbing mechanism 223 grabs the sealing sheet in the form of negative pressure. The upper end of the grabbing mechanism 223 is used to connect to the negative pressure device, and the lower end acts on the sealing sheet.

[0052] Furthermore, at the lower end of the grasping mechanism 223, there is a buffer structure, which can be in the form of a sleeve or a plurality of concentrically connected hollow tubes. An elastic member is arranged between two adjacent hollow tubes to provide buffering when the grasping mechanism 223 moves downward and contacts the aluminum foil on the packaging box, thereby reducing the downward pressure on the aluminum foil and protecting the aluminum foil.

[0053] The grabbing mechanism 223 is connected to the lifting mechanism 221 , and the lifting mechanism 221 drives the grabbing mechanism 223 to move up and down in the vertical direction.

[0054] The lifting mechanism 221 is connected to the translation mechanism 222 . The translation mechanism 222 is located between the conveying mechanism 11 and the feeding assembly 21 , and drives the lifting mechanism 221 to reciprocate between the conveying mechanism 11 and the feeding assembly 21 .

[0055] As mentioned above, the translation mechanism 222 and the lifting mechanism 221 can use a motor as a driving mechanism, and the motor drives the screw rod to rotate, thereby driving the screw rod slider to move to achieve translation or lifting. This driving method has higher precision.

[0056] refer to Figure 6 In some embodiments, the detection module 3 includes a liftable probe assembly 31 and a detection assembly 33 that cooperates with the probe assembly 31. The probe assembly 31 and the detection assembly 33 are connected by an air circuit. A probe 32 is provided at one end of the probe assembly 31 close to the packaging box. The probe 32 is connected to an air circuit for pressurizing the inside of the packaging box. After the probe 32 is extended into the packaging box, the detection assembly 33 detects the pressure inside the packaging box and controls the gas injected into the packaging box.

[0057] refer to Figure 6 The camera module 4 includes an image acquisition device 42 and an adjustable mounting bracket 41. The image acquisition device 42 is connected to the mounting bracket 41 and is set toward the second predetermined position.

[0058] The specific implementation of this detection equipment is as follows: First, the packaging box is loaded to the head end of the conveying mechanism 11 by manual or automatic loading. The conveying mechanism 11 drives the packaging box to the first predetermined position, and the first positioning component 123 and the third positioning component 125 move. The first positioning component 123 blocks the packaging box at the first predetermined position, and the third positioning component 125 blocks the packaging box moving upstream to the first predetermined position.

[0059] Then, the sealing module 2 works. The sealing module 2 first performs the step of grabbing the sealing sheet: the feeding assembly 21 starts to feed the sealing sheet, the translation mechanism 222 drives the lifting mechanism 221 and the grabbing mechanism 223 to move above the sealing sheet, and the lifting mechanism 221 moves downward so that the lower end of the grabbing mechanism 223 contacts the sealing sheet to adsorb the sealing sheet. The sealing module 2 then performs the step of transporting and pasting the sealing sheet: the grabbing mechanism 223 with the sealing sheet moves to the first predetermined position by the cooperation of the lifting mechanism 221 and the translation mechanism 222, and moves downward through the lifting mechanism 221 to paste the sealing sheet on the packaging box.

[0060] After the sealing film is pasted, the first positioning component 123 and the third positioning component 125 cancel their respective shielding on the packaging box transmission path, and at the same time, the second positioning component 124 shields the packaging box transmission path so that the packaging box stays at the second predetermined position.

[0061] Finally, the detection module 3 and the camera module 4 work, the probe assembly 31 moves downward until the probe 32 penetrates the sealing sheet and pierces the aluminum foil, and the detection assembly 33 injects gas into the packaging box through the probe 32 via the air route.

[0062] The detection module 3 is preset with a rated air pressure value. After the probe 32 penetrates the packaging box, the packaging box is slowly pressurized until the pressure inside the packaging box reaches the rated air pressure value and then the pressurization stops. If the pressure inside the packaging box decreases during the packaging process or fails to reach the rated air pressure value within a limited time, it is determined that the sealing of the closed cavity has failed and the test process is completed.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0064] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
