[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "top", "bottom", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0055] The object of the present invention is to provide a vacuum decay leak detector suitable for strip packages, which can improve the situation where the product carrier waits at a fast station and piles up at a low-speed station, thereby improving production efficiency.

[0056] See also Figure 1 and Figure 2 To achieve the above-mentioned purpose, the present invention provides a vacuum decay leak detector suitable for strip packages, including a frame, a conveying track 7, a mold cavity mover 3, a detection component and a transfer component.

[0057] The frame includes two guard plates and two fixed plates. The guard plates are provided with horizontally extending avoidance holes, which are used for part of the conveying track 7 to pass through. The two guard plates include a left guard plate 1 and a right guard plate 2, which are spaced apart and arranged in parallel with each other; the two fixed plates include a first fixed plate located on the inner side of the conveying track 7 and a second fixed plate located on the outer side of the conveying track 7, both ends of the first fixed plate and the second fixed plate are respectively connected to the left guard plate 1 and the right guard plate 2, and the first fixed plate and the second fixed plate are parallel to each other. The guard plates are provided with horizontally extending avoidance holes, which are used for part of the conveying track 7 to pass through. This makes the entire vacuum attenuation leak detector compact and reduces the overall volume of the leak detector, which can overcome the problem of large plant area occupied and plant construction cost caused by the large volume of traditional chain plate line equipment.

[0058] The conveying track 7 is fixed relative to the frame, and the conveying track 7 is arranged in a ring shape. The conveying track 7 is provided with a loading position, a detection position and a unloading position in sequence, wherein the conveying track 7 can adopt an elliptical or approximately elliptical closed track, which can achieve the above-mentioned purpose, and is not specifically limited here. Through the closed track arranged in a ring shape, the following mold cavity mover 3 can circulate along the closed track in a clockwise direction or counterclockwise direction.

[0059] The mold cavity mover 3 is movably connected to the conveying track 7, and the mold cavity mover 3 is provided with a accommodating cavity, which is used to place the product to be inspected; wherein, the conveying track 7 is a magnetic levitation track, and the mold cavity mover 3 is provided with a power source 12 for driving itself to move along the conveying track 7; a magnet is used to accurately control the movement of the mold cavity mover 3 in a frictionless propulsion manner, and a signal connection is established between the power source 12 of the mold cavity mover 3 (a magnetic drive motor module, etc. may be used) and the control system, and then combined with the annular magnetic levitation track to form an intelligent conveyor line, and through independent control of the mold cavity mover 3, the position, speed, acceleration and deceleration of the mold cavity mover 3 can be programmable, and the position of the mold cavity mover 3 can be tracked and monitored, which can greatly improve the utilization rate of the accommodating cavity of the mold cavity mover 3.

[0060] The detection component is connected to the frame, and the detection component is arranged at the detection position, and is used to detect the product to be detected that is moved to the detection position; wherein, the detection component includes a vacuum assembly and a plurality of second cylinders 6, the vacuum assembly includes a vacuum pump 11 fixed relative to the frame and a plurality of ventilation boxes 4 connected to the vacuum pump 11, and all the ventilation boxes 4 are connected to the same fixed plate; the second cylinders 6 include a second fixed end, a second piston end that can reciprocate relative to the second fixed end, and a sealing plate 5 connected to the second piston end, and all the second fixed ends are fixed to another fixed plate, and the second cylinder 6 can drive the mold cavity mover 3 located at the detection position to fit the ventilation box 4, so that the accommodating cavity is connected to the corresponding ventilation box 4.

[0061] It should be noted that, taking the product as a medicine bottle (which can be a plastic medicine bottle, a glass medicine bottle, etc.) as an example, when performing a leak detection operation, the medicine bottle is first placed in the accommodating cavity of the mold cavity mover 3. After the mold cavity mover 3 is moved to the detection position, the sealing plate 5 pushes the accommodating cavity of the mold cavity mover 3 to connect with the ventilation box 4 under the drive of the second cylinder 6. The negative pressure environment formed by the ventilation box 4 is applied to the accommodating cavity through the vacuum pump 11. The vacuum will cause the gas in the medicine bottle to overflow through the leakage hole. If liquid medicine is placed in the medicine bottle, when the vacuum degree is lower than the vapor pressure of the liquid, the liquid in the leakage channel will be vaporized, causing the air pressure in the chamber of the accommodating cavity to increase, indicating that the increase in air pressure is caused by packaging leakage.

[0062] The transfer assembly includes a loading mechanism 8 located at the loading position and a unloading mechanism 9 located at the unloading position. The loading mechanism 8 is used to transfer the product to be inspected to the corresponding accommodating cavity, and the unloading mechanism 9 is used to remove the product inspected by the inspection assembly from the accommodating cavity.

[0063] The mold cavity mover 3 runs along the annular conveying track 7 to the loading position, and the product to be inspected is transferred to the corresponding accommodating cavity through the loading mechanism 8, and then moves to the inspection position, and the product to be inspected is inspected by the inspection component. Then, the mold cavity mover 3 runs along the conveying track 7 to the unloading mechanism 9 located at the unloading position for unloading, and then continues to move to the loading position to repeat the above process. When the inspection component inspects a batch of products in the mold cavity movers 3, the remaining mold cavity movers 3 can move along the conveying track 7 to load the products to be inspected or unload the products after inspection. After a batch of products at the measuring position are inspected, they immediately move out of the testing position along the conveying track 7, and the next batch of cavity movers 3 loaded with products to be inspected enter the testing position in turn for the next group of inspections. Since all cavity movers 3 are movably connected to the conveying track 7, the moving speed of each cavity mover 3 at different positions can be controlled, which can improve the situation where the product carrier waits at the fast station and accumulates at the low-speed station, thereby improving production efficiency. The structure is simple and practical, and it operates efficiently. The speed can reach 840 lines / minute, and the detection accuracy can reach 10 microns of leakage holes.

[0064] In one of the embodiments, the conveying track 7 includes at least two long straight sections extending in a straight line, the long straight sections are parallel to each other and connected by a bending section, and all the ventilation boxes 4 are arranged in sequence at intervals along the extension direction of the same long straight section, ensuring that the mold cavity mover 3 can move quickly on the detection position arranged in a straight line (the position corresponding to the ventilation box 4 on the conveying track 7), and the unloading position and the loading position are located on another long straight section. By setting the unloading position and the loading position on the same long straight section, the mold cavity mover 3 can be quickly moved to the loading position after unloading to load the product to be tested, which can improve the operating efficiency of the entire vacuum attenuation leak detector.

[0065] See also Figure 3and Figure 4 In one embodiment, the loading mechanism 8 includes a support frame, a plurality of cavity support seats 20 and a feeding mechanism. The support frame is fixed relative to the frame body, and the support frame can be connected to the right guard plate 2; the plurality of cavity support seats 20 can be rotatably connected to the support frame, and the cavity support seat 20 is provided with a flip cavity 21 for accommodating the product, and all the cavity support seats 20 can drive the product to be inspected in the flip cavity 21 to flip from a horizontal state to a vertical state; the feeding mechanism includes a connected feeding fixed plate 31 and a feeding push plate 32, the feeding fixed plate 31 is connected to the support frame, and the feeding push plate 32 can move horizontally to push the product to be inspected in a vertical state into the corresponding accommodating cavity.

[0066] It can be understood that the strip packs are usually in a horizontal state and conveyed along the production line. The horizontal strip packs are placed into a corresponding flip mold cavity 21, and then the strip packs are flipped to a vertical state under the drive of the mold cavity support seat 20, and then enter into a accommodating cavity compatible with the vertical strip packs under the action of the feed push plate 32. For the subsequent detection process, the fusion-sealed strip products can be detected for leakage. The switching between the horizontal state and the vertical state refers to rotating the strip pack 90 degrees around the horizontally extending axis.

[0067] Among them, the feeding mechanism 8 also includes a power assembly, which includes a power source 12, a driving tooth, a rack 13, a driven tooth 14, a first pulley 16, and a second pulley 18. The power source 12 is fixed to the support frame, and the power source 12 includes a rotating shaft; the driving tooth sleeve is arranged on the rotating shaft and can rotate with the rotating shaft; the rack 13 is engaged with the driving tooth and can reciprocate relative to the support frame; the driven tooth 14 can be engaged with the rack 13, and all the driven teeth 14 are connected to the first pulley 16 coaxially arranged therewith, and the driven tooth 14 and the first pulley 16 coaxially arranged therewith are rotatably connected to the support frame through a first bearing seat 15; the second pulley 18 is connected to the first pulley 16 through a synchronous belt 17, and the second pulley 18 is fixedly connected to the corresponding mold cavity support seat 20, and the second pulley 18 and the mold cavity support seat 20 are rotatably connected to the support frame through a second bearing seat 19, so that the second pulley 18 can drive the mold cavity support seat 20 to flip.

[0068] In addition, the feeding mechanism 8 also includes a first electric cylinder 22, a cylinder member 23 and a material handling and conveying push plate 24. The fixed module of the first electric cylinder 22 is connected to the support frame; the cylinder member 23 is connected to the movable module of the first electric cylinder 22, and the cylinder member 23 includes a piston rod that can extend vertically relative to the movable module; the material handling and conveying push plate 24 is connected to the piston rod, and the first electric cylinder 22 can drive the cylinder member 23 and the material handling and conveying push plate 24 to move toward the cavity support seat 20 to drive the corresponding product to be inspected to the corresponding cavity support seat 20; specifically, the piston rod of the cylinder member 23 extends to allow the material handling and conveying push plate 24 to move toward the cavity support seat 20. The plate 24 is at a first preset height, and then the cylinder part 23 and the material handling and conveying push plate 24 are moved toward the cavity support seat 20 driven by the first electric cylinder 22 to push the horizontal strip package into the flip cavity 21 of the cavity support seat 20, and then the piston rod of the cylinder part 23 is retracted to make the material handling and conveying push plate 24 at a second preset height, which is higher than the height of the strip package, and then it is reset under the drive of the first electric cylinder 22, and at the same time, it can prevent the material handling and conveying push plate 24 from contacting the strip package on the supply line during the reset process, and then the piston rod of the cylinder part 23 is extended again, and the above process is repeated.

[0069] See also Figure 5 and Figure 6 In one embodiment, the unloading mechanism 9 includes a third fixed plate 25 and a third electric cylinder 26. The third fixed plate 25 is connected to the frame, for example, the third fixed plate 25 is connected to the side of the left guard plate 1 facing the right guard plate 2; the third electric cylinder 26 includes a fixed part connected to the third fixed plate 25, a movable part that can reciprocate relative to the fixed part, and a pushing plate 27 connected to the movable part. The pushing plate 27 is used to push the product in the accommodating cavity, wherein there can be multiple pushing plates 27, and the strip packages in multiple mold cavity movers 3 are unloaded simultaneously through one action of the third electric cylinder 26, thereby improving the unloading efficiency.
