Description

Technical Field

[0001] This invention relates to the field of cell culture flask production technology, specifically a multi-station ultrasonic welding machine for cell culture flasks. Background Technology

[0002] In vitro culture of cells and tissues has become an indispensable part of life science research and practice. A wide variety of cell types are cultured, ranging from viruses to bacteria and fungi, from human cells to animal and plant cells. Cell culture flasks are commonly used for in vitro culture of cells and tissues. While some cells and tissues can grow in suspension, a significant portion of mammalian cells require surface adhesion. Therefore, culture flasks, plates, and dishes used to provide the in vitro culture environment for cells, in addition to being highly transparent, non-toxic, and sterile, must undergo surface modification to enable adhesion, division, and growth.

[0003] In the production of cell culture flasks, the flask body and side panels need to be welded to ensure their airtightness. Ultrasonic welding machines are typically used for this process. However, welding the flask body requires manual operation: the side panels are manually aligned and pressed onto the flask body, which is then placed under the ultrasonic welding head. A hydraulic cylinder moves the ultrasonic welding head to weld the flask body and side panels. After completion, the flask is removed, and the next flask is placed for welding. This operation mode involves a large workload for workers and limits work efficiency. Therefore, to automate the alignment and placement of the side panels onto the flask body, a multi-station ultrasonic welding machine for cell culture flasks is provided. Summary of the Invention

A mounting frame 2 is fixedly connected to the top of the operating table 1. A hydraulic cylinder 3 is mounted on the outer wall of the mounting frame 2. An ultrasonic welding head 4 is connected to the output end of the hydraulic cylinder 3. The hydraulic cylinder 3 drives the ultrasonic welding head 4 to move and perform welding operations on the flask body and side plates. The flask body is moved by a moving mechanism 5. The moving mechanism 5 includes a rotating disk 501, which is rotatably connected to the top of the operating table 1. A placement seat 511 for placing the flask body is fixedly connected to the top of the rotating disk 501. A first motor 502 is mounted at the bottom of the operating table 1.

[0027] In this embodiment: when welding the bottle body and side panel, the bottle body is placed in the placement seat 511, the first motor 502 is started, the first motor 502 drives the rotating disk 501 to rotate, the rotating disk 501 drives the bottle body to move, the bottle body moves to the placement mechanism 6, the parts in the placement mechanism 6 cooperate, and the side panel is placed on the outer wall of the bottle body. The rotating disk 501 rotates and drives the bottle body to move below the ultrasonic welding head 4. The hydraulic cylinder 3 operates and drives the ultrasonic welding head 4 to move, and the welding operation is performed on the bottle body and side panel. The rotating disk 501 continues to rotate and drives the bottle body to move. The movable seat 509 moves on the transverse slide table 508. The pneumatic suction cup 510 grabs and removes the welded bottle body. This realizes multi-station processing and welding operation of bottle body and side panel, which improves welding efficiency.

[0028] Please refer to this carefully. Figures 2-7The placement mechanism 6 includes a protrusion 601, which is fixedly connected to the top of the rotating disk 501 and located on both sides of the placement seat 511. A displacement seat 602 is slidably connected to both sides of the inner cavity of the storage cylinder 506. A first spring 603 connects the displacement seat 602 and the storage cylinder 506. A slider 604 is fixedly connected to the outer wall of the displacement seat 602. A pressing rod 605 is slidably connected to one end of the slider 604 inside the storage cylinder 506, extending to the bottom of the storage cylinder 506. A groove 606 is formed on the side of the displacement seat 602 away from the slider 604. A ratchet 607 is provided in the inner cavity of the groove 606. A connecting shaft 608 is fixedly connected to both ends of the ratchet 607. The connecting shaft 608 is rotatably connected to the groove 606. The ratchet 607 and the groove 606 are connected to the outer wall of the connecting shaft 608. A torsion spring 609 is connected to the outer wall of the ratchet 607, and a support rod 610 is fixedly connected to it. The support rod 610 extends into the inner cavity of the storage cylinder 506. The placement mechanism 6 also includes a locking block 611, which is slidably connected to the inside of the displacement seat 602 and located below the ratchet 607. A second spring 612 is connected between the locking block 611 and the displacement seat 602. A push block 613 is slidably connected to the inside of the displacement seat 602 on one side of the locking block 611. The push block 613 extends out of the displacement seat 602. A support plate 614 is fixedly connected to the outer wall of the displacement seat 602 above the support rod 610. A lower pressure frame 615 is slidably connected to the bottom end of the support plate 614 inside the displacement seat 602. A second motor 616 is installed on the outer wall of the displacement seat 602. A lead screw 617 is connected to the output end of the second motor 616 and passes through the lower pressure frame 615.

[0029] In this embodiment: the side plate is placed inside the storage cylinder 506 (e.g., Figure 3 As shown), the support rod 610 supports the side plate. At this time, the locking block 611 is engaged with the ratchet 607 by the elastic force of the second spring 612, preventing the ratchet 607 from rotating, thereby preventing the support rod 610 from rotating.

[0030] When it is necessary to place the side plate on the bottle, the cylinder 504 is activated, which moves the storage cylinder 506 via the lifting plate 505 until part of the bottle enters the inner cavity of the storage cylinder 506. At this time, the protrusion 601 contacts the extrusion rod 605, pushing the extrusion rod 605 to move. The displacement of the extrusion rod 605 pushes the slider 604 to move, which in turn moves the displacement seat 602. The displacement of the displacement seat 602 moves the support plate 614 and the lower pressure frame 615 into the inner cavity of the storage cylinder 506, so that one side plate is located between the lower pressure frame 615 and the support rod 610, and the remaining side plate is located at the top of the support plate 614.

[0031] At this time, the push block 613 contacts the displacement seat 602 and moves under force. The movement of the push block 613 pushes the locking block 611 to move and separate from the ratchet 607, so that the ratchet 607 and the support rod 610 can rotate. After completion, the second motor 616 is started. The operation of the second motor 616 drives the lead screw 617 to rotate. The rotation of the lead screw 617 drives the lower pressure frame 615 to move. The lower pressure frame 615 aligns one side plate and presses it down to the top of the bottle.

[0032] Please refer to this carefully. Figures 2-4 One end of the slider 604 is provided with a first inclined surface, the top end of the extrusion rod 605 is in contact with the first inclined surface, the inside of the storage cylinder 506 is provided with a displacement groove for the displacement seat 602 to move, the displacement groove is connected to the inner cavity of the storage cylinder 506, one end of the support plate 614 and the lower pressure frame 615 are both provided with a third inclined surface, and the lower pressure frame 615 is C-shaped.

[0033] In this embodiment: the starting cylinder 504 drives the storage cylinder 506 to move through the lifting plate 505 until part of the bottle body enters the inner cavity of the storage cylinder 506. At this time, the protrusion 601 contacts the squeezing rod 605, pushing the squeezing rod 605 to move. The displacement of the squeezing rod 605 pushes the slider 604 to move. The displacement of the slider 604 drives the displacement seat 602 to move. The displacement of the displacement seat 602 drives the support plate 614 and the lower pressure frame 615 into the inner cavity of the storage cylinder 506, so that one side plate is located between the lower pressure frame 615 and the support rod 610, and the remaining side plate is located at the top of the support plate 614.

[0034] Please refer to this carefully. Figures 5-7 The top of the locking block 611 engages with the ratchet 607, and the outer wall of the locking block 611 is provided with a second inclined surface, and the push block 613 contacts the second inclined surface.

[0035] In this embodiment: the push block 613 contacts the displacement seat 602 and moves under force. The movement of the push block 613 pushes the locking block 611 to move and separate from the ratchet 607, thereby allowing the ratchet 607 and the support rod 610 to rotate.

[0036] Please refer to this carefully. Figure 5 and Figure 6 The outer wall of the lower pressure frame 615 is provided with a threaded hole, and the lead screw 617 is matched with the threaded hole.
