[0029] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] Please see attached Figure 1-3The utility model is a detection device for producing nozzle bags, comprising a clamping mechanism 1 and a detection mechanism 2, wherein the clamping mechanism 1 is used to clamp the nozzle of the nozzle bag 4; the detection mechanism 2 is arranged corresponding to the clamping mechanism 1; the clamping mechanism 1 comprises a moving block 11 and a clamp 12, and the clamp 12 is connected to the moving block 11; the detection mechanism 2 comprises a first cylinder 21, a fixing component 22 and a vacuum component 23, the first cylinder 21 is connected to the fixing component 22, and the fixing component 22 is fixedly connected to the vacuum component 23; wherein the vacuum component 23 comprises a vacuum nozzle 231 and a pressure sensor 232, the vacuum nozzle 231 is arranged corresponding to the clamp 12, and the pressure sensor 232 senses the pressure state of the vacuum nozzle 231.

[0033] Specifically, the clamp 12 is used to clamp the nozzle part of the nozzle bag 4, and the moving block 11 is used to move the nozzle bag 4 between different stations. The vacuum nozzle 231 is driven by a vacuum pump to evacuate the air in the nozzle bag 4. The first cylinder 21 drives the vacuum nozzle 231 to move up and down.

[0034] In this embodiment, the detection process is as follows: the clamp 12 of the clamping mechanism 1 clamps the nozzle bag 4, and moves to the lower end of the vacuum nozzle 231 through the moving block 11, and then the first cylinder 21 drives the vacuum nozzle 231 to descend until it docks with the nozzle of the nozzle bag 4, thereby performing a vacuum operation, and detecting the internal and external pressure changes of the nozzle bag 4 through the pressure sensor 232 to determine whether the nozzle bag 4 is leaking.

[0035] Specifically, when a spout bag 4 is evacuated and pressure is maintained, if there is air leakage inside the spout bag 4, the external atmosphere will enter the spout bag 4 through the leak point, causing the pressure inside the spout bag 4 to rise. This process measures the change in pressure inside and outside the spout bag 4 through the pressure sensor 232 to detect and determine whether the bag has air leakage. In this way, the detection mechanism 2 is used to perform online true hole leak detection and confirmation on each spout bag 4, effectively ensuring the quality of each spout bag 4, and preventing leaky bags from flowing to customer factories, thereby providing good quality assurance for the entire product market.

[0036] In some embodiments, the evacuation component 23 is symmetrically connected to the fixing component 22. The evacuation component 23 is arranged corresponding to the clamp 12, that is, two clamps 12 are preferably arranged, so that the nozzle bags 4 can be inspected in pairs, which shortens the inspection time and improves the inspection efficiency.

[0037] In some embodiments, the clamp 12 includes a body 121 and a slot 122, one end of the body 121 is fixedly connected to the moving block 11, and the slot 122 is provided at the other end of the body 121. Specifically, the slot 122 is a U-shaped slot 122, which is used to clamp the nozzle in the nozzle bag 4. The slot 122 and the nozzle are used in combination to achieve a stable placement of the nozzle in the slot 122, and at the same time, under the action of external force, it is also convenient for the nozzle to quickly load or unload from the slot 122.

[0038] In some embodiments, the detection mechanism 2 also includes a CCD camera 24 and a fill light 25. The CCD camera 24 is connected to the fixing component 22 and is arranged relative to the fixture 12. The fill light 25 is arranged corresponding to the fixture 12, and the fill light 25 is used to fill light for the CCD camera 24. Specifically, the CCD camera 24 is used to further photograph and detect the nozzle bag 4, and then transmit the status information of the nozzle bag 4 to the control system. According to the control system, the qualified sample of the nozzle bag 4 is compared to determine whether the nozzle bag 4 photographed by the CCD camera 24 is qualified, and then a qualified or unqualified signal is transmitted, so as to proceed to the next step of the action direction. Among them, the control system is achievable by existing program programming. In addition, the fill light 25 is used to increase the brightness around the nozzle bag 4, thereby improving the clarity and accuracy of the CCD camera 24 shooting.

[0039] Embodiment 2:

[0040] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the detection device of the utility model.

[0041] See also Figures 4 to 6 , and also includes a rejection mechanism 3, which is arranged on one side of the detection mechanism 2, and a moving block 11 moves between the rejection mechanism 3 and the detection mechanism 2. Among them, the rejection mechanism 3 is used to reject the unqualified suction spout bag 4 detected by the detection mechanism 2. The moving block 11 moves the suction spout bag 4 from the station of the detection mechanism 2 to the station of the rejection mechanism 3, realizing the detection of the suction spout bag 4 and the rejection of unqualified ones, and the action connection is tight, thereby improving the efficiency of identifying and rejecting unqualified suction spout bags 4.

[0042] Specifically, the rejecting mechanism 3 includes a rejecting component 31 and a waste collecting component 32, wherein the rejecting component 31 is disposed above the fixture 12, the waste collecting component 32 is disposed opposite to the rejecting component 31, and the waste collecting component 32 is disposed below the fixture 12. The rejecting component 31 takes the unqualified nozzle bag 4 out of the fixture 12, so that the unqualified nozzle bag 4 falls into the waste collecting component 32.

[0043] The rejecting component 31 includes a shifting block 311, a second cylinder 312 and a pushing cylinder 313. The lower end of the second cylinder 312 is connected to the shifting block 311, and one end of the pushing cylinder 313 is connected to the lifting cylinder. Specifically, the shifting block 311 is an inverted L-shaped shifting block 311.

[0044] Through the setting of the above-mentioned rejection mechanism 3, the specific rejection action is: when the detection mechanism 2 detects the unqualified signal of the nozzle bag 4, the unqualified signal is transmitted to the control system, and then the control system starts the rejection component 31 to operate. When the moving block 11 moves to the bottom of the rejection mechanism 3 with the clamp 12, the second cylinder 312 is started, driving the shifting block 311 to descend to be parallel with the nozzle bag 4, and then the shifting block 311 is driven to move away from the moving block 11 by starting the pushing cylinder 313, so that the shifting block 311 pushes the unqualified nozzle bag 4 to disengage from the card slot 122, so that the unqualified nozzle bag 4 falls into the waste collecting component 32, and the unqualified nozzle bag 4 is rejected. The overall action process has a strong rhythm and a good rejection effect. And through the setting of the shape of the shifting block 311, the pushing cylinder 313 and the nozzle bag 4 are cleverly connected to ensure the smoothness of the rejection operation.

[0045] See also Figure 6 The waste collecting component 32 includes a collecting pipe 321 and a storage box 322. The collecting pipe 321 is arranged between the shifting block 311 and the storage box 322. The collecting pipe 321 includes a tube body 3211 and a guide plate 3212. The guide plate 3212 is connected to both sides of the tube body 3211. The collecting pipe 321 gradually decreases from a height close to one end of the clamp 12 to a height close to one end of the storage box 322. After the unqualified nozzle bag 4 falls into the collecting pipe 321, due to the gravity of the nozzle bag 4 itself, it will slide through the collecting pipe 321 to the storage box 322, thereby achieving unified collection and facilitating subsequent operations. Through the setting of the guide plate 3212, it is effectively ensured that the unqualified nozzle bag 4 falls into the storage box 322 according to a suitable path, thereby avoiding the falling of the unqualified nozzle bag 4.

[0046] Embodiment 3:

[0047] Based on the above embodiment, this embodiment provides a nozzle welding machine, including the above detection device. Each nozzle bag 4 produced by the nozzle welding machine can be tested for air leakage, ensuring the quality of each nozzle bag 4 and preventing leaking bags from flowing to customer factories, thereby providing good quality assurance for the entire product market.
