DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In one embodiment of the utility model, a bottle air tightness detection device is disclosed, such as Figure 1 As shown, the bottle air tightness detection device includes a supporting assembly, a displacement driving assembly and a clamping assembly, and the displacement driving assembly and the clamping assembly are arranged on the supporting assembly.

[0029] Specifically, the support assembly includes a lower base plate 1, a support platform 2 and an upper base plate 3 which are arranged in parallel from bottom to top. The upper base plate 3 and the lower base plate 1 are connected by a guide column 4, that is, the upper end of the guide column 4 is fixedly connected to the upper base plate 3, and the lower end of the guide column 4 is fixedly connected to the lower base plate 1. The upper base plate 3, the lower base plate 1 and the guide column 4 form a support frame for the bottle air tightness detection device. The support platform 2 is used to carry the bottle body 5 and can move between the upper base plate 3 and the lower base plate 1 along the length direction of the guide column 4; wherein the number of the guide columns is multiple, preferably four, and the four guide columns are respectively arranged at the four corners of the upper base plate and the lower base plate, thereby realizing stable support for the upper base plate and the lower base plate.

[0030] Furthermore, the displacement driving component is at least partially disposed on the upper substrate 3 , and the displacement driving component can drive the supporting platform 2 to move between the upper substrate 3 and the lower substrate 1 , that is, the supporting platform 2 can be close to or away from the upper substrate 3 .

[0031] In addition, the clamping assembly is arranged on the support platform 2, and is used for clamping and fixing the bottle body 5, so that the bottle body 5 to be detected can be firmly fixed on the support platform 2. The clamping assembly includes a front clamping plate 6, a rear clamping plate 7 and a first driving source 8. Among them, the first driving source is an air drive rod, the cylinder body of the air drive cylinder is fixed on the support platform, and the piston rod of the air drive rod is fixedly connected with the rear clamping plate. Of course, the first driving source can also be other driving devices. Specifically, the front clamping plate 6 is fixed on the support platform 2, and the rear clamping plate 7 is arranged parallel to the front clamping plate 6. The first driving source 8 can drive the rear clamping plate 7 to move relative to the front clamping plate 6 in a direction perpendicular to the parallel plane of the rear clamping plate 7 and the front clamping plate 6. In this way, the rear clamping plate 7 is driven by the first driving source 8 to approach the front clamping plate 6, so that the two ends of the bottle body 5 are clamped and fixed between the front clamping plate 6 and the rear clamping plate 7, and the rear clamping plate 7 is driven by the first driving source 8 to move away from the front clamping plate 6, so that the bottle body 5 can be taken out from between the front clamping plate 6 and the rear clamping plate 7. The rear clamping plate and the front clamping plate can clamp and fix multiple bottles at the same time, and the bottles are arranged side by side.

[0032] It should be noted that when the bottle air tightness detection device performs a sealing test on the bottle body 5, the bottle air tightness detection device needs to be partially placed in liquid (water) so that when the displacement driving component drives the support platform 2 to move to the uppermost end (the end close to the upper substrate 3), the bottle body 5 on the support platform 2 can completely leave the liquid surface; when the displacement driving component drives the support platform 2 to move to the lowermost end (the end close to the lower substrate 1), the bottle body 5 on the support platform 2 can be completely immersed in the liquid.

[0033] In summary, in the bottle air tightness detection device of the present embodiment, a clamping assembly is provided so that the bottle can be clamped and fixed on the supporting platform. After the bottle is filled with air, the supporting platform is driven downward by the displacement driving assembly to immerse the bottle in the liquid, and then the sealing quality of the bottle can be judged by whether bubbles are coming out of the bottle. The bottle air tightness detection device has the advantages of simple structure, easy operation, small size, easy handling and maintenance, and low manufacturing cost.

[0034] In this embodiment, if Figure 1 As shown, a front sleeve 9 is provided on the front clamping plate 6, and a rear sleeve 10 is provided on the rear clamping plate 7. The front sleeve 9 and the rear sleeve 10 are in corresponding positions and are respectively used to limit the two ends of the bottle body 5. When the bottle body 5 is clamped and fixed, the front end of the bottle body 5 is just located in the front sleeve 9, and the rear end of the bottle body 5 is just located in the rear sleeve 10, thereby limiting the bottle body 5 and preventing the bottle body 5 from being separated from the rear clamping plate 7 and the front clamping plate 6 when the air tightness is detected. Among them, the front sleeve is detachably arranged on the front clamping plate, and the rear sleeve is also detachably arranged on the rear clamping plate. In this way, when clamping and fixing bottles of different bottle diameters, the front sleeve and the rear sleeve of different diameters can be replaced to ensure that the front sleeve and the rear sleeve can adapt to the bottle body.

[0035] In addition, an air pipe connector is provided in the front sleeve 9, one end of which can be connected to the opening of the bottle body 5, and the other end of which passes through the first through hole 11 on the front clamping plate 6. Specifically, when the front clamping plate 6 and the rear clamping plate 7 clamp the bottle body 5, one end of the air pipe connector can be tightly abutted against the opening of the bottle body 5, and at this time, gas can be injected into the bottle body 5 through the other end of the air pipe connector. In this way, when the displacement driving assembly drives the supporting platform 2 to move toward the lower substrate 1, gas can be injected into the bottle body 5 through the air pipe connector, thereby shortening the time for the air tightness detection of the bottle body 5 and improving the detection efficiency.

[0036] Of course, in other embodiments, the trachea connector can also be arranged in the rear sleeve, a first through hole is opened on the rear splint, and the other end of the trachea connector passes through the first through hole and out of the rear splint to be connected to the air pump device.

[0037] In addition, a slide rail (not shown in the figure) is provided on the support platform 2, and the direction of the slide rail is set along the moving direction of the rear clamping plate 7. The lower end of the rear clamping plate 7 is provided with a slide groove that cooperates with the slide rail, so that the rear clamping plate 7 can move stably on the support platform 2.

[0038] In this embodiment, if Figure 1 As shown, the clamping assembly further comprises a support plate 12 .

[0039] The support plate 12 is fixed on the support platform 2 between the front clamping plate 6 and the rear clamping plate 7. The upper end of the support plate 12 is provided with an arc groove, which is used to accommodate the bottle body of the bottle body 5. When the bottle body 5 is placed on the bottle body air tightness detection device, the front end of the bottle body 5 can be inserted into the front sleeve 9 first, and the bottle body of the bottle body 5 is supported by the support plate 12 to ensure that the bottle body 5 is in the horizontal direction, so that when the first driving source 8 drives the rear clamping plate 7 to approach the front clamping plate 6, the rear end of the bottle body 5 is just inserted into the rear sleeve 10; at the same time, the support plate 12 can also bear most of the weight of the bottle body 5, reducing the load of the front sleeve 9 and the rear sleeve 10.

[0040] Furthermore, a guide rail 13 is provided on the support platform 2 between the front clamping plate 6 and the rear clamping plate 7. The guide rail 13 is arranged along the moving direction of the rear clamping plate 7. A limit block (not shown in the figure) is provided on the guide rail 13. The limit block is used to limit the position of the rear clamping plate 7 when it moves, so as to prevent the bottle body 5 from being squeezed and deformed due to excessive movement of the rear clamping plate 7. In addition, by adjusting the different positions of the limit block on the guide rail 13, the clamping needs of bottles 5 of different lengths can be achieved. In this way, during the operation, it is necessary to first determine the length of the bottle body 5, then adjust the specific position of the limit block on the guide rail 13, and fix the limit block on the guide rail 13 by fixing parts such as screws.

[0041] In addition, if Figure 1 As shown, the displacement driving assembly includes a driving rod 14 and a second driving source 15 .

[0042] The second driving source 15 is arranged on the upper substrate 3, and a second through hole is formed on the upper substrate 3. The lower end of the driving rod 14 is fixedly connected to the supporting platform 2, and the upper end of the driving rod 14 passes through the upper substrate 3 through the second through hole and is in transmission connection with the second driving source 15. The second driving source 15 can drive the driving rod 14 to move axially, thereby realizing that the supporting platform 2 is close to or away from the upper substrate 3. Among them, the second driving source is an air-driven cylinder; the cylinder body of the air-driven cylinder is fixedly connected to the upper substrate, and the piston rod of the air-driven cylinder is fixedly connected to the driving rod. Of course, the second driving source can also be other driving devices.

[0043] In addition, a guide hole is opened on the support platform 2, and the guide column 4 passes through the support platform 2 through the guide hole. The guide hole can slide relative to the guide column 4, and the movement of the support platform 2 can be guided through the guide hole, making the support platform 2 more stable during movement.

Under the above teaching of the present invention, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present invention, and the protection scope of the present invention shall be based on the protection scope of the claims.
