[0035] 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.

[0036] 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.

[0037] In the description of the present invention, it is necessary to understand that the terms "up", "down", "left" and "right" etc. indicate directions or positional relationships based on the directions 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 positions or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0038] The purpose of the present invention is to provide a flexible conveying vacuum attenuation leak detection machine, which can improve the situation where the carrier of the product waits at a fast station and piles up at a low-speed station, thereby improving production efficiency.

[0039] See also Figure 1 and Figure 2 To achieve the above-mentioned purpose, the present invention provides a flexible conveying vacuum attenuation leak detector, including a frame, a conveying track 200, a plurality of detection cavity movers 300 and a plurality of detection components. The conveying track 200 is fixed relative to the frame, and the conveying track 200 is arranged in a ring shape, wherein the conveying track 200 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 detection cavity mover 300 can circulate along the closed track in a clockwise direction or a counterclockwise direction.

[0040] Several detection cavity movers 300 are all movably connected to the conveying track 200. The detection cavity movers 300 are all provided with a accommodating cavity, which is used for placing the product to be inspected. The loading mechanism can be used to enable the product to be quickly moved into the accommodating cavity of the detection cavity mover 300 at the loading position to achieve rapid loading. The same detection cavity mover 300 has two accommodating cavities, and the two accommodating cavities are adjacently arranged along the moving direction of the detection cavity mover 300 to improve the inspection efficiency of the product.

[0041] Several detection components are connected to the frame, and all detection components are arranged in sequence along the running direction of the detection cavity mover 300. When all detection components have detection cavity movers 300 at the detection positions, all detection components simultaneously detect the products to be detected at the detection positions. Multiple detection components can be used to improve product detection efficiency. For example, when six detection components are set, six groups of products to be detected can be detected at the same time in the same batch, greatly shortening the product detection time.

[0042] Among them, the conveying track 200 is a magnetic levitation track, and the detection mold cavity mover 300 is provided with a power source for driving itself to move along the conveying track 200. The movement of the detection mold cavity mover 300 is precisely controlled by a magnet in a frictionless propulsion manner. By establishing a signal connection between the power source of the detection mold cavity mover 300 (a magnetic drive motor module, etc. can be used) and the control system, and then combining it with the annular magnetic levitation track to form an intelligent conveyor line, through independent control of the detection mold cavity mover 300, the position, speed, acceleration and deceleration of the detection mold cavity mover 300 can be programmable, and at the same time, the position of the detection mold cavity mover 300 can be tracked and monitored, which can greatly improve the utilization rate of the accommodating cavity of the detection mold cavity mover 300.

[0043] When all the inspection components are inspecting the products to be inspected at the inspection position, the remaining inspection cavity movers 300 can move along the conveying track 200 to load the products to be inspected or unload the products after inspection. After the inspection of a batch of products at the inspection position is completed, they immediately move out of the inspection position along the conveying track 200, and the next batch of inspection cavity movers 300 loaded with products to be inspected enter the inspection position in turn for the next group of inspections. Since all the inspection cavity movers 300 can be movably connected to the conveying track 200, the moving speed of each inspection cavity mover 300 at different positions can be controlled, which can improve the situation where the product carrier waits at the fast station and piles up at the low-speed station, thereby improving production efficiency.

[0044] In this embodiment, the detection components include a ventilation box 410 and two groups of cylinder assemblies 420. The ventilation box 410 is fixed relative to the frame. The ventilation box 410 includes two chambers that are arranged opposite to each other and can form a negative pressure environment. The two groups of cylinder assemblies 420 are arranged on both sides of the ventilation box 410, and the cylinder assemblies 420 are provided with a push plate 430 that can move toward the corresponding chamber. The detection assembly also includes a standard mold cavity mover 440, which is arranged corresponding to a group of cylinder assemblies 420. The standard mold cavity mover 440 can be driven to fit one side of the ventilation box 410 through the push plate 430 of the cylinder assembly 420 to connect one chamber; the detection mold cavity mover 300 can move to the detection position and be driven to fit the other side of the ventilation box 410 by the push plate 430 of the other group of cylinder assemblies 420 to connect another chamber.

[0045] 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 detection mold cavity mover 300, and after the detection mold cavity mover 300 is moved to the detection position, it is driven by the cylinder assembly 420 to achieve communication with a chamber on the ventilation box 410, and a negative pressure environment is formed in the chamber to apply a vacuum to the accommodating cavity. 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 liquid vapor pressure, the liquid in the leakage channel will be vaporized. If the air pressure in the chamber connected to the accommodating cavity is higher than the air pressure in the chamber connected to the standard mold cavity mover 440, it means that the increase in air pressure is caused by packaging leakage.

[0046] Among them, in the same detection component, a first sealing ring 450 is provided on the side of the ventilation box 410 facing the cylinder assembly 420, and a second sealing ring 460 is provided on the side of the push plate 430 facing the ventilation box 410. The sealing effect is improved by the first sealing ring 450 and the second sealing ring 460. The first sealing ring 450 and the second sealing ring 460 can both be O-rings. The setting position and setting method of the first sealing ring 450 and the second sealing ring 460 can also be adjusted according to actual conditions as long as the above-mentioned purpose can be achieved.

[0047] All standard cavity movers 440 can be relatively arranged on the same side of all ventilation boxes 410. For specific arrangement methods, please refer to Figure 1 , six standard cavity movers 440 are all arranged below the six ventilation boxes 410, and the six standard cavity movers 440 are respectively connected with cylinder assemblies 420 below. There are six detection cavity movers 300 running to the detection position above the six ventilation boxes 410, and six cylinder assemblies 420 are respectively arranged above the six detection cavity movers 300. The twelve cylinder assemblies 420 act simultaneously, so that the push plate 430 can push the detection cavity mover 300 located above the ventilation box 410 and the standard cavity mover 440 located below the ventilation box 410 to fit on both sides of the ventilation box 410 to perform leak detection on the product. In addition, the detection assemblies can be added or reduced, and the cylinder assemblies 420 can be individually controlled according to actual detection needs to achieve the purpose of independent detection.

[0048] Attach Figure 1 The detection mold cavity mover 300, the conveying track 200 and the detection assembly shown in the example are used as an example to illustrate that when located Figure 1 After the six detection mold cavity movers 300 from left to right in the lower middle part complete the detection at the detection position of the detection assembly, the cylinder assembly 420 contracts at the same time, and the six detection mold cavity movers 300 quickly move out of the detection position and are located at the same time. Figure 1The first six detection cavity movers 300 described in a clockwise direction in the upper middle section are quickly loaded in sequence at the loading position and moved to the detection position for detection. Specifically, the first detection cavity mover 300 from left to right at the top is loaded and then moves counterclockwise to the first detection position from right to left at the bottom. When the first detection cavity mover 300 from left to right is loaded and leaves the loading position, the second detection cavity mover 300 enters the loading position to load. After that, the second detection cavity mover 300 from left to right at the top is loaded and then moves counterclockwise to the second detection position from right to left at the bottom, and so on. After the detection is completed, it moves out of the detection position to unload or reject the product, and then repeats the next cycle. This can avoid the problem of the time required for multiple cavities to work at one station and then be transferred to the next station in the prior art.

[0049] In one embodiment, the Figure 1 The first detection mold cavity mover 300 position from left to right in the upper middle portion is used as the loading position, the third detection mold cavity mover 300 position from left to right is used as the unloading position, and the fourth detection mold cavity mover 300 position from left to right is used as the waste rejection position to blow away and kick out unqualified products.

[0050] In one embodiment, the conveying track 200 includes at least one long straight section extending in a straight line, and all the detection components are sequentially arranged at intervals in the same long straight section to ensure that the detection cavity mover 300 can move quickly on the detection positions arranged in a straight line.

[0051] In another embodiment, the conveying track 200 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, all the detection components are arranged in sequence at intervals on the same long straight section, and the above-mentioned unloading position and the above-mentioned 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 detection cavity mover 300 can be quickly moved to the loading position after unloading to load the product to be detected, which can improve the operating efficiency of the entire flexible conveying vacuum attenuation leak detector.

[0052] The frame includes two guard plates 110 and two fixed plates 120. The two guard plates 110 are spaced apart and arranged in parallel with each other. The guard plates 110 are provided with horizontally extending avoidance holes, and the avoidance holes are used for allowing part of the conveying track 200 to pass through; the two fixed plates 120 are spaced apart, and both ends of the two fixed plates 120 are connected to the two guard plates 110 to make the entire frame stable. At the same time, the facing side of the two fixed plates 120 is used to fix the fixed end of the cylinder assembly 420, so that the entire flexible conveying vacuum attenuation leak detector has a compact structure 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.

[0053] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
