Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding equipment technology, specifically to an ultrasonic welding device for preventing leaks in cell culture flasks. Background Technology

[0002] Cell culture flasks are typically assembled from a body and a cap using ultrasonic welding. Existing ultrasonic welding equipment usually employs a fixed upper welding head and a simple lower mold clamp.

[0003] In actual welding processes, slight shape tolerances in the bottle body or alignment deviations during manual placement can prevent the bottle body flange and cap flange from being perfectly parallel and aligned. Under welding pressure, this misalignment causes welding energy and pressure to concentrate in localized areas, resulting in incomplete or weak welds. Other areas may not be fully fused, leading to discontinuous welds that compromise the airtightness of the culture bottle during long-term storage or transportation. This can result in culture medium contamination or leakage, severely impacting the reliability and biosafety of cell experiments. To address these issues, we propose an ultrasonic welding device for leak-proof cell culture bottles. Utility Model Content

The clamping plate has a through groove that matches the shape of the upper part of the bottle cap. Four sliding columns are fixedly welded to the top wall of the clamping plate. The four sliding columns are slidably connected in the through holes of the four fixed seats. A spring spring is sleeved on the sliding column. The two ends of the spring spring are fixedly connected to the fixed seat and the clamping plate, respectively.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: an ultrasonic welding device for preventing leaks in cell culture flasks, comprising: The base 1 has a column 2 fixedly installed on its rear side wall, and an ultrasonic welding machine body 3 fixedly installed on the front side wall of the column 2. The ultrasonic welding machine body 3 is a publicly available technology, and its specific structure is not described in detail. A welding head 4 is installed on the ultrasonic welding machine body 3, and a clamping mechanism 5 is provided on the welding head 4. A placement seat 6 is fixedly installed on the top wall of the base 1, and a placement groove 7 adapted to the shape of the lower part of the cell culture bottle is opened on the top wall of the placement seat 6. The clamping mechanism 5 includes four fixed seats 8 and a clamping plate 9. The four fixed seats 8 are respectively fixedly installed in the middle of the four side walls of the welding head 4. The clamping plate 9 is located below the welding head 4. The clamping plate 9 has a through groove 10 that matches the shape of the upper part of the bottle cap. Four sliding columns 11 are fixedly welded to the top wall of the clamping plate 9. The four sliding columns 11 are slidably connected in the through holes of the four fixed seats 8. A spring spring 12 is sleeved on the sliding column 11. The two ends of the spring spring 12 are fixedly connected to the fixed seat 8 and the clamping plate 9 respectively.

[0015] Both sides of the placement seat 6 are provided with mounting seats 13. The mounting seats 13 are fixedly installed on the top wall of the base 1. Cylinders 14 are fixedly installed on the mounting seats 13. V-shaped clamping plates 15 are fixedly installed on the opposite ends of the two cylinders 14. The two cylinders 14 can drive the two V-shaped clamping plates 15 to move towards each other, thereby positioning and clamping the cell culture flask body.

[0016] Two guide posts 16 are fixedly welded onto the V-shaped clamping plate 15. The guide posts 16 are slidably connected in the through hole of the mounting base 13. The guide posts 16 facilitate the guidance of the V-shaped clamping plate 15 and prevent it from deflecting.

[0017] The V-shaped clamping plate 15 has anti-slip texture 17 on its clamping surface, which can prevent the cell culture flask from deflecting after being clamped.

[0018] The cylinder 14 is electrically connected to the main controller of the peripheral device.

[0019] Working principle: In use, the cell culture flask is placed in the placement slot 7 of the placement seat 6. Then, the two cylinders 14 are controlled by the external controller to move the two V-shaped clamping plates 15 towards each other to clamp and fix the cell culture flask. Then, the cap is placed on the top of the flask. The ultrasonic welding machine body 3 is started, which moves the welding head 4 downward. During the downward movement of the welding head 4, the pressure plate 9 moves downward. The pressure plate 9 is sleeved on the upper part of the cap through the through slot 10. As the welding head 4 descends, it compresses the elastic spring 12. The elastic force generated by the compressed elastic spring 12 acts on the pressure plate 9, so that the pressure plate 9 presses the cap tightly, making the cap and the flask flange in close contact. Then, the welding head 4 continues to move downward and fits against the top of the cap. Then, the ultrasonic energy is activated to realize the ultrasonic welding of the cap and the flask.
