Description

Technical Field

[0001] The present application relates to the technical field of glass bottle production, and in particular to a bottle bottom concavity detection device. Background Art

[0002] Vials, ampoules, and other containers are currently very commonly used for packaging liquid pharmaceuticals. During their production, production technicians and quality inspectors must inspect the product's appearance and dimensions to ensure compliance with standards. Testing for bottom concavity is a crucial yet often overlooked aspect. While a large bottom concavity can increase the bottle's strength against positive pressure, lateral pressure, and internal pressure, it can also reduce the contact surface between the bottle and the machine, leading to tipping of the bottle during production. Generally, the bottom concavity of bottles containing injections can be minimized. For viscous drugs or those with high liquid levels, the bottom concavity should be increased, or as much as possible. Furthermore, the extent of the bottom concavity, like the bottom thickness, directly affects the freeze-drying time and profile. For drugs with particularly high liquid levels, increasing the wall thickness and the bottom concavity can be used to minimize breakage during freeze-drying. Furthermore, the bottom concavity should be neither concave nor convex; products that protrude beyond the bottom plane will tip over and must be immediately scrapped.

[0003] However, existing online automatic inspection equipment is generally unable to detect bottom concavity. In particular, when using image-based inspection methods, bottles with severely convex bottoms can only be rejected, and in most cases, unqualified bottles are released. Therefore, bottle bottom concavity is highly dependent on random inspections. Chinese Patent No. 202321054000.0 discloses a device for detecting the bottom concavity of vials. While this device achieves concavity detection at a low cost, the measurement method is not automated or accurate enough, and only simple judgments can be made. It also lacks the ability to easily output results, hindering the storage and traceability of test results during production. Utility Model Content

[0033] Figures 1 to 4An embodiment of the bottle bottom concavity detection device of the present application is schematically shown.

[0034] like Figures 1 to 4 As shown, the present application discloses a bottle bottom concavity detection device, comprising a detection assembly 1, which includes a detection platform 11 and a linear capacitive barrier detection mechanism 12 mounted on the detection platform 11. The linear capacitive barrier detection mechanism 12 comprises a fixed-end sensor 121 and a movable-end detection rod 122. The movable-end detection rod 122 vertically passes through the fixed-end sensor 121 and is capable of vertical reciprocating movement, with the lower end of the movable-end detection rod 122 aligned with the bottle inverted area of the detection platform 11. A control and output assembly 2 is electrically connected to the linear capacitive barrier detection mechanism 12.

[0035] When in use, the bottle body 3 to be inspected is placed upside down on the inspection platform 11, so that the movable end inspection rod 122 is located above the bottom of the bottle. In this way, the movable end inspection rod 122 can be pulled down to measure the drop t between the edge of the bottle bottom and the middle of the bottle bottom (reference Figures 5 and 6 The concavity data of the bottom of the bottle is obtained to check whether the concavity of the bottom of the bottle is qualified.

[0036] Through the above-mentioned structural design, the present application can utilize the vertically movable movable end detection rod 122 to quickly and accurately detect the concavity of the bottom of the inverted syringe bottle or ampoule bottle waiting for inspection on the detection table 11, and transmit the electrical signal through the electrical connection structure so that the control and output components can obtain the concavity data, with a higher degree of automation and accuracy, and convenient output, storage and traceability of the concavity data, which is more in line with modern production needs and is conducive to improving the production quality of glass bottles.

[0037] In some embodiments of the present application, reference is made to Figures 2 to 3As shown, the middle section of the moving end detection rod 122 is configured as a moving gate region 1221. A series of moving gate metal rings of the same size are evenly distributed in the moving gate region 1221, and each moving gate metal ring is insulated from each other. Correspondingly, corresponding to the moving gate region 1221 of the moving end detection rod 122, a series of fixed gate metal rings of the same size are provided in the fixed end sensor 121. Each fixed gate metal ring is insulated from each other, and a gap is left between the fixed gate metal rings and the moving gate metal rings. The moving gate metal rings and the fixed gate metal rings can be formed by plating or scratching. Based on the above structure, according to the principle of capacitive gate sensors, between the fixed end sensor 121 and the moving end detection rod 122, each fixed gate metal ring and the moving gate metal ring forms a capacitor. These capacitors are connected in parallel. According to electric field theory and ignoring edge effects, they have variable capacitance, which is related to the relative position of the fixed end sensor 121 and the moving end detection rod 122. As the moving-end detection rod 122 continuously moves vertically parallel to the fixed-end sensor 121, the relative coverage length of each pair of capacitors changes periodically, and the capacitance value also changes accordingly. After circuit processing, the linear displacement value can be measured, thereby obtaining the bottom concavity data of the bottle body 3 to be inspected. It is understood that the principles of capacitive barrier sensors are well understood by those skilled in the art and will not be further elaborated here.

[0038] In some embodiments of the present application, reference is made to Figure 3 As shown, on the moving end detection rod 122, limit plates 1222 are provided at the upper and lower ends of the moving grid area 1221. The limit plates 1222 radially protrude from the moving end detection rod 122 to prevent the moving grid area 1221 from moving out of the fixed end sensor 121, thereby ensuring that the relative position of the moving end detection rod 122 and the fixed end sensor 121 does not exceed the detection range.

[0039] In some embodiments of the present application, the limiting piece 1222 and the fixed end sensor 121 are relatively fixedly connected via a spring (not shown). Specifically, the limiting piece 1222 at the upper end is connected to the fixed end sensor 121, and the limiting piece 1222 at the lower end is connected to the fixed end sensor 121, respectively, by a spring, so that the moving end detection rod 122 is limited to the center of the fixed end sensor 121. While ensuring that the moving grid metal ring and the fixed grid metal ring are well matched, it is convenient for the moving end detection rod 122 to automatically reset to the center position of the fixed end sensor after the measurement is completed. The spring can be an ordinary cylindrical or truncated cone spring, etc., which is arranged in a sleeve manner to improve the concentric stability of the moving end detection rod 122 and the fixed end sensor 121.

[0040] In some embodiments of the present application, Figures 1 to 3As shown, the lower end of the movable end detection rod 122 is configured as a cone, which facilitates insertion into the bottom area of the bottle body 3 to detect concavity, without being affected by narrow bottom areas or deep concavities. The tip of the cone is polished to a smooth shape to avoid damaging the bottle body 3 to be inspected, thus preventing product damage during spot checks and improving product yield.

[0041] In some embodiments of the present application, to prevent wear and corrosion of the device and increase its service life, the lower conical structure of the movable end detection rod 122 is cast from stainless steel. This ensures strength while resisting corrosion and ensuring durability. Specifically, the rod body of the movable end detection rod 122 can be made of a plastic material, such as polyurethane, to balance durability and lightweight requirements and facilitate the insulation design of the movable gate metal ring. The lower conical structure of the movable end detection rod 122 is cast from stainless steel and connected to the plastic rod body.

[0042] In some embodiments of the present application, reference is made to Figure 1 and Figure 2 As shown, a vertically mounted support column 111 is provided on the testing platform 11. Support column 111 is a retractable structure, and the linear barrier detection mechanism 12 is mounted on the testing platform 11 via support column 111. Therefore, when changing product batches, resulting in significant changes in the height of the bottles 3 to be inspected, the present application can adapt to the inspection of bottles of different sizes by adjusting the height of support column 111 without replacing the structural mold, thereby improving the applicability of the detection device. Specifically, support column 111 can be configured as an inner and outer tube sleeve, with positioning holes and positioning bolts used to achieve telescopic height adjustment.

[0043] In some embodiments of this application, continue to refer to Figure 1 and Figure 2 As shown, in this embodiment, the testing platform 11 is provided with four support columns 111, which are arranged in a rectangular pattern at the four bottom corners of the linear capacitive barrier detection mechanism 12. This horizontally positions the linear capacitive barrier detection mechanism 12, effectively maintaining the vertical position of the movable end detection rod 122, parallel to the bottle body 3 to be inspected, and ensuring the accuracy of the bottle bottom concavity detection. To facilitate the leveling process, the testing platform 11 can be equipped with a spirit level, and the four bottom corners of the testing platform 11 can be provided with adjustment nuts to facilitate quick and easy observation and adjustment.

[0044] In some embodiments of the present application, the testing platform 11 is further provided with a bottle mouth holder (not shown), which is provided with a bottle mouth placement groove that matches the bottle body 3 to be tested. During testing, the bottle mouth of the bottle body 3 to be tested can be stably placed upside down on the testing platform 11 through the bottle mouth placement groove, thereby facilitating the pulling of the movable end testing rod 122 to contact the bottle bottom for testing, thereby avoiding the impact of testing accuracy due to the bottle body 3 to be tested (such as an ampoule) having a too small bottle mouth or not standing firmly.

[0045] In some embodiments of the present application, the detection component 1 also includes a processing chip and an acquisition card (installed inside the shell of the linear capacitance barrier detection mechanism 12, not shown in the figure). The processing chip is connected to the linear capacitance barrier detection mechanism 12 through the acquisition card to convert the electrical signal into data information representing concavity.

[0046] In some embodiments of the present application, reference is made to Figure 1 As shown, the control and output component 2 includes: a controller 21, and a printing mechanism and / or a display mechanism connected to the controller 21, and the controller 21 is electrically connected to the linear capacitance detection mechanism 12. Among them, the control and output component 2 can be integrated, such as Figure 1 As shown, a controller 21, a key panel 22 connected to the controller 21, a display 23 and a printing outlet (not shown) are integrated on a host computer to conveniently realize detection control, data display, data reading, output and storage, and facilitate the presentation and tracing of detection results.

[0047] Combine Figures 1 to 4 As shown, the workflow of the embodiment of the present application is described:

[0048] 1. Before measurement, the testing platform 11 should be adjusted to a horizontal position. If necessary, an adjustment nut can be installed below the testing platform 11 to facilitate the adjustment of the testing platform 11. Then, the fixed-end sensor 121 should be kept horizontal by adjusting the four support columns 111. The purpose of adjusting the fixed-end sensor 121 to a horizontal position is to keep the moving-end detection rod 122 in a vertical position so that the moving-end detection rod 122 and the bottle body 3 to be tested are in the same vertical direction during testing, thereby avoiding system errors.

[0049] 2. Place the bottle 3 to be inspected with its bottom facing upward on the inspection platform 11. Pull the movable end inspection rod 122 downward until it is close to the outer edge of the bottle bottom. During this process, keep the bottle mouth in full contact with the inspection platform 11, that is, keep the bottle 3 to be inspected vertical. To this end, a bottle mouth fixing base can be added. The bottle mouth positioning groove of the bottle mouth fixing base can be used to stably and horizontally place the bottle 3 to be inspected.

[0050] 3. Through the control and output component 2, the state of the moving end detection rod 122 in step 2 is set to the initial position, that is, "zero".

[0051] 4. Gently move the bottle body 3 to be inspected and pull the moving end detection rod 122 to move it to the center of the bottom of the bottle. Figure 4 As shown, the value read at this time is the value of the bottom concavity.

[0052] 5. Repeat steps 2 to 4 to obtain multiple sets of data. By automatically calculating and counting, the average value is obtained and output, and the concavity detection is completed. The concavity data is obtained and saved. Generally, it is meaningful to measure each bottle body 3 2-3 times.

[0053] 6. After the measurement is completed, loosen the moving end detection rod 122 and allow it to return to its initial position under the action of the spring.

[0054] 7. When replacing the bottle body 3 to be inspected with a different size, it is only necessary to adjust the four support columns 111 on the inspection platform 11 to meet different size requirements.

[0055] Therefore, through this application, the height of the four support columns 111 can be adjusted to adapt to the detection of bottles of different sizes without replacing the module, and the detection data is an electrical signal, which is convenient for processing and storage, conducive to data traceability, and more in line with modern inspection and testing requirements.

[0056] In summary, the technical solution of the present application is a bottle bottom concavity detection device comprising: a detection component and a control and output component. The detection component comprises a detection platform and a linear capacitance grid detection mechanism mounted on the detection platform. The linear capacitance grid detection mechanism comprises: a fixed-end sensor and a movable-end detection rod. The movable-end detection rod passes vertically through the fixed-end sensor and can move vertically back and forth. The lower end of the movable-end detection rod is aligned with the inverted bottle area of the detection platform. The control and output component is electrically connected to the linear capacitance grid detection mechanism to obtain the degree of concavity. The present application utilizes a vertically movable movable-end detection rod to quickly and accurately detect the concavity of the bottoms of inverted vials or ampoules on the detection platform, and obtains concavity data through the control and output component. This provides a higher degree of automation and accuracy, and facilitates the output, storage, and tracing of concavity data.
