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 directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “backward”, “left” and “right” are 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. They do not indicate or imply that the positions or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limitations of the present invention.

[0038] The invention aims to provide a strip packaging bag leak detection device which can realize automatic loading and unloading of materials, sealing detection, and rejection of unqualified products, thereby improving production efficiency and being suitable for factory assembly line production.

[0039] To achieve the above object, the present invention provides the following technical solutions:

[0040] See also Figures 1 to 7 The present embodiment provides a strip packaging bag leak detection device, comprising: an annular conveyor belt 02 installed on a frame 01, a material receiving station 03, a sealing detection station 04 and a material unloading and waste removal station 05 arranged in sequence along the conveying direction of the annular conveyor belt 02, a material input station 06 is arranged at one end of the annular conveyor belt 02 close to the material receiving station 03, and a material output station 07 is arranged at the end of the annular conveyor belt close to the material unloading and waste removal station 05, the material input station 06 is used to collect the material 08 delivered by the front-end equipment and push the material 08 into the first material box cavity 09 of the material receiving station 03, the first material box cavity 09 moves with the annular conveyor belt 02 to transport the material 08 to the sealing detection station 04 for sealing leak detection, and the first material box cavity 09 continues to move to the material unloading and waste removal station 05 after passing through the sealing detection station 04 to remove the material 08 or transfer it to the material output station 07.

[0041] That is to say, the ring conveyor belt 02 is installed on the frame 01, and along the conveying direction of the conveyor belt of the ring conveyor belt 02, a material receiving station 03, a sealing detection station 04 and a material unloading and waste material removal station 05 are arranged, and a material input station 06 is arranged on one side of the material receiving station 03, and a material output station 07 is arranged on one side of the waste material removal station; the material input station 06 is used to process multiple incoming materials from the front-end equipment, and the materials 08 are sorted here. When the material box of the material input station 06 is full, and at this time the material box happens to be located at the material receiving station 03 After the first material box cavity 09 is aligned, the material 08 is pushed into the first material box cavity 09 by a dedicated loading cylinder, and the first material box cavity 09 will move forward with the circular conveyor belt 02, leaving the material receiving station 03, and enter the sealing detection station 04, where the first material box cavity 09 will be sealed and the material 08 therein will be leak-checked. After the inspection, the first material box cavity 09 will enter the unloading and waste rejection station 05, and the qualified materials 08 in the first material box cavity 09 will be pushed into the material output station 07 for unloading, while the unqualified ones will be rejected.

[0042] Specifically, in order to achieve effective docking with the material 08 from the previous process equipment of this embodiment, the material box and the material box ring conveyor of the material input station 06 of this embodiment are used to process the multiple incoming materials from the front-end equipment. Each material box contains 12 strips (it can also be compatible with 6, 10, 15, etc.), that is, every 12 strips are collected as 1 group, and the material boxes are evenly distributed on the material box ring conveyor of the material input station 06. After each plate of material boxes is full of material, the material box ring conveyor rotates. When 3 groups are collected and the material boxes are facing the material receiving station 03, the 3 groups of strips are pushed into the first material box cavity 09 of the material receiving station 03 by the loading cylinder and the push plate thereon. The inlet of the first material box cavity 09 is set as an open opening to facilitate the docking of material 08 with multiple ports.

[0043] With such settings, automatic loading and unloading of material 08, sealing detection and rejection of defective products can be achieved, which improves production efficiency, reduces manual labor load, and is more suitable for factory assembly line production.

[0044] Preferably, the first material box cavity 09 is connected to the endless conveyor belt 02 in a floating elastic manner, and both sides of the bottom surface of the first material box cavity 09 are connected to the endless conveyor belt 02 via springs 10 .

[0045] Furthermore, the sealing detection station 04 includes: a first cylinder 11, a first push plate 12 and a sealing box body 13; the first cylinder 11 is vertically installed on the frame 01, and the first cylinder 11 is located below the first material box cavity 09; the first push plate 12 is installed at the movable end of the first cylinder 11, and is used to push the first material box cavity 09 to move upward; the sealing box body 13 is located above the first material box cavity 09, and it is arranged opposite to the first push plate 12, and the sealing box body 13 is used to cover the first material box cavity 09 to seal the first material box cavity 09.

[0046] In this embodiment, taking the first material box cavity 09 as an example, when arriving at the sealing inspection station, the sealing leak detection process for this group of materials 08 begins. Since this embodiment adopts the vacuum decay method for leak detection, its basic process is: after arriving in place, the first material box cavity 09 moves toward the top sealed box body 13 under the drive of the first cylinder 11 installed at the bottom, and seals the material 08 in the first material box cavity 09 into the sealed box body 13. Then the sealing detection instrument starts to work, and the closed first material box cavity 09 is vacuumed, pressure balanced, and tested for small and large leaks. After completing the above work, the cylinder is retracted. In this station, each first material box cavity 09 corresponds to an independent detection instrument, and each first material box cavity 09 is analyzed separately to ensure the accuracy of the test data.

[0047] It should be noted that the first material box cavity 09 can be set to a certain elastic float through a compression spring (or tension spring, etc.), so that the first material box cavity 09 can be reset after the sealing test to facilitate loading and unloading. In addition to using the bottom cylinder to push the material box cavity to achieve sealing, the material box cavity can also be moved upward to achieve sealing by using a cam or other methods. This article does not make specific restrictions here.

[0048] Furthermore, the sealed box body 13 is a square box body with an opening at the bottom, and a flexible sealing ring 14 is provided at the bottom edge of the sealed box body 13 .

[0049] like Figure 5 and Figure 6 As shown, in order to increase the sealing effect between the sealing box body 13 and the first material box cavity 09, the sealing box body 13 is set as a square box body with an open lower end, and the volume of the sealing box body 13 just matches the first material box cavity 09, so that the sealing box body 13 can be completely mounted on the outer periphery of the first material box cavity 09. At the same time, a flexible sealing ring 14 is also provided at the bottom of the side wall of the sealing box body 13. In this way, the sealing effect of the first material box cavity 09 can be better.

[0050] Preferably, unlike some devices that use direct pressure detection, which is easily affected by environmental factors, has low precision and poor sensitivity, the differential pressure method used in this embodiment is used to determine whether the product is leaking. It is a non-destructive, non-destructive quantitative measurement method, and its principle is similar to a balance: during the detection, we will vacuum the object to be measured and the reference object for the same time, and enter the pressure holding stage after the vacuuming is completed, so that the pressure on both sides of the differential pressure sensor diaphragm is completely equal, and observe the balance on both sides. If the object to be measured does not leak, the diaphragm of the differential pressure sensor will be in a balanced state, and the differential pressure output is zero. If there is a leak in the object to be measured, the diaphragm of the differential pressure sensor will be in an unbalanced state, and the differential pressure caused by the leak can be detected at the same time. Preferably, this embodiment adopts a detection process of first detecting a small leak (Cycle1 cycle) and then detecting a large leak (Cycle2 cycle). The specific process principle is: first, the object to be measured placed in the detection cavity (i.e., the first material box cavity 09) and the reference object placed in the standard cavity are vacuumed and then pressure-balanced to see if there is a small differential pressure to determine whether there is a small leak. If there is no slight differential pressure, open the automatic volumetric valve to make the pressure in the test cavity consistent with the pressure in the standard cavity. If there is a large leak, the gas will not only fill the space between the object being tested and the test cavity, but also enter the object being tested. At this time, the pressure in the test cavity will be lower than the pressure in the reference cavity, resulting in a differential pressure.

[0051] Preferably, the unloading and waste removal station 05 includes: a second cylinder 15 and a second push plate 16; the second cylinder 15 is arranged above the first material box mold cavity 09; the second push plate 16 is installed at the movable end of the second cylinder 15, and the second push plate 16 can extend into the first material box mold cavity 09 to push out the material 08.

[0052] Specific as Figure 7 As shown, the material unloading and waste material removal station 05 is mainly used to complete the unloading of qualified products and the removal of unqualified products, and the material 08 is pushed out from the first material box mold cavity 09 by the second cylinder 15 and the second push plate 16 thereon.

[0053] Furthermore, a rotatable transition platform 17 is provided on the frame 01 , and the transition platform 17 can connect the unloading and waste removal station 05 with the material output station 07 , and a collection box 18 is placed under the transition platform 17 .

[0054] Specific as Figure 7 As shown, in the process of material 08 being pushed out of the first material box cavity 09, the intermediate transition platform 17 is set as a mechanism that can be flipped open and closed, which can be flipped by a cylinder or an electric cylinder at a certain angle. If the product detected is qualified, the transition platform 17 will not be flipped, that is, the transition platform 17 remains horizontal, so that the material unloading and waste removal station 05 and the material output station 07 can be connected, and the material 08 can be pushed to the material output station 07. This station is mainly used to complete the sorting of material 08 and convey qualified material 08 to the back-end equipment. In order to achieve a good docking of material 08 with the back-end equipment, this station needs to complete the sorting of material 08 and output it backward in an orderly manner in the same posture; if the product detected is unqualified, the transition platform 17 is flipped, so that there will be a gap between the material unloading and waste removal station 05 and the material output station 07, and the material 08 will fall directly. At the same time, a waste collection box 18 is set at the lower end of this position, and the collection box 18 can complete the collection of unqualified material 08. Preferably, the material 08 can also be taken out from the first material box cavity 09 by a combination of a cylinder pneumatic gripper or a robot arm, and the taken out qualified material 08 is directly placed on the conveyor belt of the material output and material sorting station, and the unqualified materials are removed by releasing the gripper midway (i.e., at the intermediate transition platform 17).

[0055] Preferably, the material receiving station 03 is further provided with a second material box mold cavity 19 and a third material box mold cavity 20, and the first material box mold cavity 09, the second material box mold cavity 19 and the third material box mold cavity 20 are arranged at intervals.

[0056] like Figure 2As shown, in order to speed up the detection efficiency in this embodiment, three groups of material box mold cavities are set on the circular conveyor belt at the same time, namely the first material box mold cavity 09, the second material box mold cavity 19 and the third material box mold cavity 20, and the three are arranged at intervals; in this way, the first material box mold cavity 09 can be loaded while the second material box mold cavity 19 is being tested at the sealing detection station and the third material box mold cavity 20 is unloading. In this way, each station is always in action, which can speed up the leakage detection efficiency of material 08.

[0057] Of course, in the present embodiment, three groups of material box mold cavities are provided. In actual production, a suitable number of groups of material box mold cavities may also be provided according to actual needs, and no specific limitation is made herein.

[0058] Preferably, the first material box mold cavity 09 is driven by a first servo motor 21 , the second material box mold cavity 19 is driven by a second servo motor 22 , and the third material box mold cavity 20 is driven by a third servo motor 23 .

[0059] Specifically, in this embodiment, different material box mold cavities are driven by different servo motors, which is convenient for regulation in actual production.

[0060] Preferably, the first material box mold cavity 09 , the second material box mold cavity 19 and the third material box mold cavity 20 can all be detachably mounted on the endless conveyor belt 02 .

[0061] It can be understood that the first material box mold cavity 09, the second material box mold cavity 19 and the third material box mold cavity 20 can be set to a quick-release type, so that the material box mold cavity can be quickly replaced to adapt to the production of materials 08 of different specifications, which is convenient and fast.

[0062] Preferably, a blowing and drying station 24 is provided below the endless conveyor belt 02 for cleaning and drying the first material box mold cavity 09 , the second material box mold cavity 19 and the third material box mold cavity 20 that pass through.

[0063] In this embodiment, a blowing and drying station 24 can also be set at the lower position of the circular conveyor belt 02, which can blow and dry the material box mold cavity passing through, especially the material box mold cavity that leaks unqualified material 08. The purpose is to ensure the dryness of the material box mold cavity, because if there is liquid medicine or it is very humid, it will affect the next inspection results of other materials 08 in the mold cavity, that is, the material 08 that is not leaking will be judged as unqualified.

[0064] In addition, in this embodiment, the material box mold cavity is arranged on the circular conveyor belt 02, and each station is arranged along the circular conveyor belt 02, and except for the purging and drying station, the other stations are arranged at the upper layer of the circular conveyor belt 02; in another embodiment, specifically as Figure 8As shown, the material box mold cavity is arranged on two parallel strip conveyor belts distributed in upper and lower layers, that is, the two conveyor belts are independently horizontal, but it should be noted that the conveying directions of the two conveyor belts are opposite; wherein, in this embodiment, the material box mold cavity can be moved between the upper and lower layers by a vertical lifting mechanism arranged at the ends of the two conveyor belts; it can be understood that with such arrangement, the material box mold cavity will always be in an upright state, so that a working station can also be set on the conveyor belt located on the lower layer, unlike the circular conveyor belt 02, where the work station can only be set on the upper layer of the circular conveyor belt 02, thus saving a lot of space.

[0065] 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.

[0066] 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.

[0067] The embodiments provided by the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the present invention.
