Description

Technical Field

[0001] This utility model relates to a laser detection clamping structure and detection method for ampoules and vials. Background Technology

[0002] Ampoules are hard glass containers that can be melt-sealed and are commonly used to store injectable drugs, vaccines, serums, etc., while vials are small bottles with rubber stoppers and aluminum-plastic composite caps, generally used for packaging vaccines, biological agents, powder injections, freeze-dried drugs, etc. These two types of glass bottles are common packaging bottles in the pharmaceutical industry.

[0003] After filling, ampoules and vials need to be tested for their airtightness. Currently, most ampoules and vials leaks are detected using the vacuum attenuation method. This method establishes a vacuum condition, under which gas or liquid inside the glass vial will overflow into the test chamber. By monitoring the change in vacuum pressure within the test chamber, a leak can be determined. While this method can detect minute leaks in the vial, each vial must be evacuated during testing, which takes a long time. Furthermore, compared to laser detection, the vacuum attenuation method is less efficient. Currently, laser detection technology is not yet mature in China, and most of the technology is monopolized by foreign countries.

[0004] Currently, wavelength modulation spectroscopy can be utilized in China. Spectroscopy (WMS) technology can be used to detect gas content, but other laser detection technologies can also be used. In these methods, the glass bottle to be tested needs to be placed on a rotating base and rotated, so that the laser beam can be incident on the bottle at different angles. This averages out the signal intensity fluctuations caused by interference effects, effectively reducing abnormal signal fluctuations that may be caused by incident at a single angle, and further improving accuracy. For example, patent application number CN201510876677.6 discloses a bottle laser detection method that uses the bottle's self-rotation to increase detection accuracy. However, the bottle needs to be confined to the rotating base during rotation, otherwise it is easy to fly off the rotating base under the rotational force. Another example is patent application number 201420495069.1, which discloses an online laser detection device for bottles. The bottle can be pressed down by a pressure head and then rotated. However, this structure requires the bottle to be placed upright. If the bottle is slightly tilted after the pressure head is pressed down, it is easy to fly off during rotation, and the tilted bottle will also affect the final detection result. Therefore, it is very inconvenient to carefully observe whether it is upright in each operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a laser detection clamping structure for ampoules and vials. The structure is simple, can be locked onto the rotating seat according to different bottle diameters, has a wide range of applications, and is more convenient to operate.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A laser detection clamping structure for ampoules and vials includes a base and a rotary motor. The rotary motor is mounted on the bottom side of the base. A disc-type conductive fixed slip ring is fixed to the upper end of the base. A disc-type conductive rotating slip ring is rotatably connected to the inner side of the disc-type conductive fixed slip ring. A bottom support circular plate is fixed to the bottom end of the disc-type conductive rotating slip ring. The output end of the rotary motor is fixed at the center of the bottom support circular plate. A support frame is fixed to the top of the disc-type conductive rotating slip ring. An electric push rod is mounted on the support frame. A silicone head is fixed to the telescopic end of the electric push rod.

[0008] A further technical solution is that a bearing is fixed at the center of the top of the base, and the output end of the rotary motor is built into the bearing and rotatably connected to the bearing, which can stabilize the output end of the rotary motor and reduce sway.

[0009] A further technical solution is that the disc-type conductive rotary slip ring is electrically connected to the electric push rod. Through the electrical connection, the electric push rod can push the silicone head to clamp the bottle body to be inspected.

[0010] A further technical solution is that the silicone head has a "C" shaped structure, which fits snugly against the outer wall of the bottle to be inspected, making the clamping more secure.

[0011] A further technical solution is that the top of the base, and inside the disc-type conductive fixed slip ring, is provided with an inner groove. The disc-type conductive rotating slip ring and the bottom support circular plate are both located in the inner groove, making reasonable use of space and leaving the upper part of the bottle to be inspected for laser detection.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a laser detection clamping structure for ampoules and vials. It conducts electricity between a disc-type conductive rotating slip ring and a disc-type conductive fixed slip ring, so the external power supply is not affected by rotation. It can directly drive the electric push rod to clamp the bottle body to be inspected. It is also suitable for clamping and inspecting bottles of different diameters. During inspection, the bottle body to be inspected only needs to be placed into the bottom support circular plate. There is no need to straighten it, making the operation more convenient.

[0019] See Figures 1 to 3 As shown, a laser detection clamping structure for ampoules and vials includes a base 6 and a rotary motor 7. The rotary motor 7 is installed on the bottom side of the base 6. A disc-type conductive fixed slip ring 4 is fixed on the upper end of the base 6. A disc-type conductive rotary slip ring 3 is rotatably connected to the inner side of the disc-type conductive fixed slip ring 4. A bottom support circular plate 5 is fixed at the bottom end of the disc-type conductive rotary slip ring 3. The output end of the rotary motor 7 is fixed at the center of the bottom support circular plate 5. A support frame 10 is fixed at the top of the disc-type conductive rotary slip ring 3. An electric push rod 2 is installed on the support frame 10. A silicone head 11 is fixed at the telescopic end of the electric push rod 2.

[0020] A bearing 8 is fixed at the center of the top of the base 6. The output end of the rotary motor 7 is built into the bearing 8 and rotatably connected to it, which can stabilize the output end of the rotary motor 7 and reduce sway. The disc-type conductive rotary slip ring 3 is electrically connected to the electric push rod 2. Through the electrical connection, the electric push rod 2 can push the silicone head 11 to clamp the bottle body 1 to be inspected. The silicone head 11 has a "C" shaped structure and fits against the outer wall of the bottle body 1 to be inspected, making the clamping more secure. The top of the base 6, inside the disc-type conductive fixed slip ring 4, also has an inner groove 9. The disc-type conductive rotary slip ring 3 and the bottom support circular plate 5 are both located in the inner groove 9, making reasonable use of space and leaving the upper side of the bottle body 1 to be inspected for laser detection. The electric push rod 2 is a miniature pen-type electric push rod, which has stable pushing force and is compact.

[0021] In this embodiment, the bottle body 1 to be inspected is first placed randomly on the bottom support circular plate 5. The disc-type conductive fixed slip ring 4 and the disc-type conductive rotating slip ring 3 are a complete set of conductive slip rings. The disc-type conductive fixed slip ring 4 is connected to an external power source, so that the disc-type conductive rotating slip ring 3 is also energized. During clamping, the disc-type conductive rotating slip ring 3 is electrically connected to the electric push rod 2, which drives the electric push rod 2 to start. The start of the electric push rod 2 drives the silicone head 11 to clamp the bottle body 1 to be inspected from left to right. The bottle body 1 to be inspected can be an ampoule or a vial. After clamping, the rotary motor 7 is started. The output end of the rotary motor 7 drives the bottom support circular plate 5 to rotate. The bottom support circular plate 5 then drives the disc-type conductive rotating slip ring 3 to rotate. In this way, the laser detector can detect the rotating bottle body 1 to be inspected, improving the detection accuracy.
