Description

Technical Field

[0001] This invention relates to the field of medical testing equipment technology, and in particular to a vacuum attenuation leak detector suitable for strip packaging. Background Technology

[0002] Existing vacuum decay leak detectors all use traditional conveying methods. Because traditional mechanical conveying systems bind all the workpieces together, the inevitable difference in production cycle time between workstations causes waiting at high-speed workstations and accumulation at low-speed workstations, making it impossible to achieve continuous production and severely restricting production efficiency.

[0003] Therefore, how to provide a flexible conveying vacuum decay leak detection machine to improve production efficiency is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a vacuum decay leak detector suitable for strip packaging, which can improve the situation of product carriers waiting at high-speed stations and accumulating at low-speed stations, thereby improving production efficiency.

[0021] Preferably, the feeding mechanism further includes:

[0022] The first electric cylinder, the fixing module of the first electric cylinder is connected to the support frame;

[0023] A cylinder assembly, connected to the movable module of the first electric cylinder, the cylinder assembly including a piston rod capable of extending vertically relative to the movable module;

[0024] The material feeding and conveying pusher plate is connected to the piston rod. The first electric cylinder can drive the cylinder component and the material feeding and conveying pusher plate to move toward the mold cavity support seat, so as to move the corresponding product to be tested onto the corresponding mold cavity support seat.

[0025] Preferably, the frame includes:

[0026] Two protective panels, including a left protective panel and a right protective panel, are spaced apart from each other and arranged in parallel.

[0027] The two fixing plates include a first fixing plate located inside the conveying track and a second fixing plate located outside the conveying track. The two ends of the first fixing plate and the second fixing plate are respectively connected to the left guard plate and the right guard plate, and the first fixing plate and the second fixing plate are parallel to each other.

[0028] Preferably, the detection component includes:

[0029] The vacuum assembly includes a vacuum pump fixed relative to the frame and several vent boxes connected to the vacuum pump, all of which are connected to the same fixed plate.

[0030] Several second cylinders include a second fixed end, a second piston end capable of reciprocating relative to the second fixed end, and a sealing plate connected to the second piston end. All second fixed ends are fixed to another fixed plate. The second cylinders can drive the mold cavity mover located at the detection position to fit against the vent box, so that the receiving cavity communicates with the corresponding vent box.

[0031] Preferably, the feeding mechanism includes:

[0032] The third fixing plate is connected to the frame.

[0033] The third electric cylinder includes a fixed member connected to the third fixed plate, a movable member capable of reciprocating relative to the fixed member, and a pusher plate connected to the movable member, the pusher plate being used to push the product out of the receiving cavity.

[0040] The mold cavity movers travel along a circular conveyor track to the loading position, where the products to be tested are transferred to the corresponding receiving cavity by the loading mechanism. They then move to the testing position, where the testing components inspect the products. Afterward, the mold cavity movers travel along the conveyor track to the unloading mechanism at the unloading position for unloading. They then continue to the loading position, repeating the above process. While the testing components are inspecting products in one batch of mold cavity movers, the remaining mold cavity movers can move along the conveyor track to load products to be tested or unload products after testing. After one batch of products at the testing position is inspected, it immediately moves out of the testing position along the conveyor track. The next batch of mold cavity movers carrying products to be tested then enters the testing position for the next set of tests. Because all mold cavity movers are movably connected to the conveyor track, the moving speed of each mold cavity mover at different positions can be controlled. This improves the situation where product carriers wait at high-speed stations and accumulate at low-speed stations, thereby increasing production efficiency. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] In the description of this invention, it should be understood that the terms "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this invention.

[0055] The purpose of this invention is to provide a vacuum decay leak detector suitable for strip packaging, which can improve the situation of product carriers waiting at high-speed stations and accumulating at low-speed stations, thereby improving production efficiency.

[0056] Please see Figure 1 and Figure 2 To achieve the above objectives, the present invention provides a vacuum decay leak detector suitable for strip packages, comprising 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 have horizontally extending clearance holes for partial passage of the conveyor track 7. The two guard plates include a left guard plate 1 and a right guard plate 2, which are spaced apart and arranged parallel to each other. The two fixed plates include a first fixed plate located inside the conveyor track 7 and a second fixed plate located outside the conveyor track 7. The two ends of the first and second fixed plates are respectively connected to the left guard plate 1 and the right guard plate 2, and the first and second fixed plates are parallel to each other. The guard plates have horizontally extending clearance holes for partial passage of the conveyor track 7, which makes the entire vacuum attenuation leak detector compact and reduces the overall volume of the leak detector. This overcomes the problems of large size of traditional chain plate line equipment, which leads to large factory area and factory construction costs.

[0058] The conveying track 7 is fixed relative to the frame and is arranged in a ring. The conveying track 7 is provided with a loading position, a detection position and a unloading position in sequence. The conveying track 7 can be an elliptical or approximately elliptical closed track, as long as it can achieve the above purpose. No specific limitation is made here. Through the closed track arranged in a ring, the mold cavity mover 3 can be made to run in a clockwise or counterclockwise direction along the closed track.

[0059] The mold cavity mover 3 is movably connected to the conveying track 7. Each mold cavity mover 3 is provided with a receiving cavity for placing the product to be tested. The conveying track 7 is a magnetic levitation track. Each mold cavity mover 3 is provided with a power source 12 to drive itself to move along the conveying track 7. The movement of the mold cavity mover 3 is precisely controlled by using magnets to propel it in a frictionless manner. By establishing a signal connection between the power source 12 of the mold cavity mover 3 (which can be a magnetic drive motor module, etc.) and the control system, and then combining it with the circular magnetic levitation track to form an intelligent conveyor line, the position, speed, acceleration and deceleration of the mold cavity mover 3 can be programmed through independent control of the mold cavity mover 3. At the same time, the position of the mold cavity mover 3 can be tracked and monitored, which can greatly improve the utilization rate of the receiving cavity of the mold cavity mover 3.

[0060] The detection component is connected to the frame and set at the detection position for detecting the product to be tested when it is moved to the detection position. The detection component includes a vacuuming component and several second cylinders 6. The vacuuming component includes a vacuum pump 11 fixed relative to the frame and several ventilation boxes 4 connected to the vacuum pump 11. All ventilation boxes 4 are connected to the same fixed plate. Each of the second cylinders 6 includes 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. All second fixed ends are fixed to another fixed plate. The second cylinders 6 can drive the mold cavity mover 3 located at the detection position to fit against the ventilation box 4 so that the receiving cavity is connected to the corresponding ventilation box 4.

[0061] It should be noted that, taking a medicine bottle (which can be a plastic medicine bottle, a glass medicine bottle, etc.) as an example, when performing leak detection, the medicine bottle is first placed in the receiving 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 receiving cavity of the mold cavity mover 3 to connect with the ventilation box 4 under the drive of the second cylinder 6. The vacuum pump 11 creates a negative pressure environment in the ventilation box 4 to apply a vacuum to the receiving cavity. The vacuum will cause the gas in the medicine bottle to overflow through the leak hole. If the medicine bottle contains liquid medicine, when the vacuum degree is lower than the liquid vapor pressure, the liquid in the leak channel will vaporize, causing the air pressure in the cavity of the receiving cavity to rise. This indicates that the rise in air pressure is caused by packaging leakage.

[0062] The transfer assembly includes a feeding mechanism 8 located at the feeding position and a discharging mechanism 9 located at the discharging position. The feeding mechanism 8 is used to transfer the product to be tested to the corresponding receiving cavity, and the discharging mechanism 9 is used to remove the product after it has been tested by the testing assembly from the receiving cavity.

[0063] The cavity mover 3 travels along the circular conveyor track 7 to the loading position, where the product to be tested is transferred to the corresponding receiving cavity by the loading mechanism 8. It then moves to the testing position, where the testing component tests the product. Afterward, the cavity mover 3 travels along the conveyor track 7 to the unloading mechanism 9 at the unloading position for unloading, and then continues to move to the loading position, repeating the above process. While the testing component is testing a batch of products within the cavity movers 3, the remaining cavity movers 3 can move along the conveyor track 7 to load products to be tested or unload products after testing. After a batch of products at the testing station is inspected, it immediately moves out of the testing station along the conveyor track 7. The next batch of mold cavity movers 3, which are loaded with products to be inspected, enter the testing station in sequence for the next set of inspections. Since all mold cavity movers 3 can be movably connected to the conveyor track 7, the moving speed of each mold cavity mover 3 at different positions can be controlled. This can improve the situation of product carriers waiting at high-speed stations and accumulating at low-speed stations, thereby improving production efficiency. The structure is simple and practical, and the operation is highly efficient. The speed can reach 840 pieces / minute, and the detection accuracy can reach 10 micrometers of leakage holes.

[0064] In one embodiment, the conveying track 7 includes at least two long straight sections that extend in a straight line. The long straight sections are parallel to each other and connected by a bending section. All the ventilation boxes 4 are arranged sequentially at intervals along the same long straight section to ensure that the mold cavity mover 3 can move quickly on the detection positions (positions on the conveying track 7 corresponding to the ventilation boxes 4) arranged in a straight line. 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 move quickly to the loading position after unloading to load the product to be tested, which can improve the operating efficiency of the entire vacuum decay leak detector.

[0065] Please see Figure 3and Figure 4 In one embodiment, the feeding mechanism 8 includes a support frame, a plurality of mold cavity support seats 20, and a feeding mechanism. The support frame is fixed relative to the frame body and can be connected to the right guard plate 2. The plurality of mold cavity support seats 20 are rotatably connected to the support frame. The mold cavity support seats 20 are provided with a flipping mold cavity 21 for accommodating products. All mold cavity support seats 20 can drive the product to be tested located in the flipping mold cavity 21 to flip from a horizontal state to a vertical state. The feeding mechanism includes a feeding fixing plate 31 and a feeding push plate 32 connected to each other. The feeding fixing plate 31 is connected to the support frame, and the feeding push plate 32 can move horizontally to push the product to be tested in a vertical state into the corresponding accommodating cavity.

[0066] Understandably, the strip package is usually in a horizontal state and is conveyed along the production line. By placing the horizontal strip package into the matching flipping mold cavity 21, the strip package is flipped to a vertical state under the action of the mold cavity support seat 20. Then, under the action of the feeding push plate 32, it enters the receiving cavity that matches the vertical strip package for subsequent testing. This process can detect whether the fusible strip product is leaking. The switching between the horizontal and vertical states refers to rotating the strip package 90 degrees around the horizontally extending axis.

[0067] The feeding mechanism 8 also includes a power assembly, which includes a power source 12, a drive gear, a rack 13, a driven gear 14, a first pulley 16, and a second pulley 18. The power source 12 is fixed to the support frame and includes a rotating shaft. The drive gear is sleeved on the rotating shaft and can rotate with the rotating shaft. The rack 13 meshes with the drive gear and can reciprocate relative to the support frame. The driven gear 14 can mesh with the rack 13. All driven gears 14 are connected to the first pulley 16, which is coaxially arranged with them. The driven gears 14 and the first pulley 16 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. The second pulley 18 is fixedly connected to the corresponding mold cavity support seat 20. 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 rotate.

[0068] In addition, the feeding mechanism 8 also includes a first electric cylinder 22, a pneumatic cylinder 23, and a material feeding and conveying pusher 24. The fixed module of the first electric cylinder 22 is connected to the support frame; the pneumatic cylinder 23 is connected to the movable module of the first electric cylinder 22, and the pneumatic cylinder 23 includes a piston rod that can extend vertically relative to the movable module; the material feeding and conveying pusher 24 is connected to the piston rod. The first electric cylinder 22 can drive the pneumatic cylinder 23 and the material feeding and conveying pusher 24 to move toward the mold cavity support seat 20, so as to move the corresponding product to be inspected onto the corresponding mold cavity support seat 20; specifically, the piston rod of the pneumatic cylinder 23 extends to make the material feeding and conveying pusher 24 move toward the mold cavity support seat 20. Plate 24 is at a first preset height. Then, cylinder 23 and material conveying push plate 24 move toward mold cavity support 20 under the drive of first electric cylinder 22, pushing the horizontal strip into the flipping mold cavity 21 of mold cavity support 20. Then, the piston rod of cylinder 23 retracts to make material conveying push plate 24 reach a second preset height, which is higher than the height of the strip. Then, it resets under the drive of first electric cylinder 22, which can prevent material conveying push plate 24 from contacting the strip on the supply line during the reset process. Then, the piston rod of cylinder 23 extends again and repeats the above process.

[0069] Please see Figure 5 and Figure 6 In one embodiment, the feeding 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 member connected to the third fixed plate 25, a movable member that can reciprocate relative to the fixed member, and a pusher plate 27 connected to the movable member. The pusher plate 27 is used to push out the product in the receiving cavity. There can be multiple pusher plates 27. The strips in multiple mold cavity movers 3 are fed simultaneously by one action of the third electric cylinder 26, thereby improving the feeding efficiency.

[0070] Please see Figure 7 and Figure 8 In one embodiment, a scrap kicking mechanism 10 located between the detection position and the unloading position is also included. The scrap kicking mechanism 10 includes a fourth fixed plate 28 and a plurality of fourth cylinders 29. The fourth fixed plate 28 is connected to the frame. For example, the fourth fixed plate 28 can be connected to the side of the left guard plate 1 away from the right guard plate 2. Each of the plurality of fourth cylinders 29 includes a fourth fixed end connected to the fourth fixed plate 28, a fourth piston end that can reciprocate relative to the fourth fixed end, and a scrap kicking push plate 30 connected to the fourth piston end. Through precise control of the fourth cylinders 29, the scrap kicking push plate 30 can push out the defective products in the receiving cavity. One or a group of defective products can be removed by one fourth cylinder 29, or multiple or more groups of defective products can be removed by multiple fourth cylinders 29 operating simultaneously.

[0071] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
