Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic transmission technology, specifically a multi-station pneumatic sample transmission workstation. Background Technology
[0002] In fields such as medical care, scientific research, and industrial production, it is often necessary to transfer samples to multiple workstations. Currently used pneumatic sample transfer workstations are prone to collisions with components inside the workstation when the pneumatic transfer cylinder reaches the designated workstation due to the high transfer speed. This can damage the internal samples and affect subsequent testing or processing.
[0003] The existing workstation has shortcomings in its buffer structure design, resulting in poor buffering effect and difficulty in effectively solving the problem of internal sample damage caused by excessively fast transport speed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a multi-station pneumatic sample transfer workstation, which has the advantage of buffering the pneumatic transfer cylinder and solves the problem of damage to internal samples caused by excessively high transfer speed.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station pneumatic sample transfer workstation, including a base, a workstation housing fixedly connected to the top of the base, a controller provided on the outside of the workstation housing, a magnetic door hinged to the outside of the workstation housing, a handle fixedly connected to the outside of the magnetic door, and a buffer mechanism provided inside the workstation housing.
[0006] The buffer mechanism includes a support plate, which is fixedly connected to the inner wall of the workstation housing. A first spring is fixedly connected to the top of the support plate, a support block is fixedly connected to the top of the first spring, and a snap-fit box is fixedly connected to the top of the support block. A magnetic block is provided inside the snap-fit box, a locking block is fixedly connected to one end of the magnetic block, and a second spring is provided outside the magnetic block.
[0007] Preferably, the magnetic block extends through the second spring to the outside of the buckle box, with one end of the second spring fixedly connected to the inner wall of the buckle box and the other end fixedly connected to the buckle block.
[0008] Preferably, an electromagnet is fixedly connected to the top of the support block, and the electromagnet is located on the left side of the magnetic block.
[0009] Preferably, a limiting block is fixedly connected to the left side of the support block, and a limiting groove is formed on the inner wall of the workstation shell. The left side of the limiting block is T-shaped and is engaged with the inner wall of the limiting groove.
[0010] Preferably, a rubber pad is fixedly connected to the outside of the card block, and the side of the rubber pad that contacts the pneumatic transmission cylinder is arc-shaped.
[0011] Preferably, a sponge pad is fixedly connected to the inner bottom wall of the workstation housing, and an infrared beam sensor is fixedly connected to the top of the buckle box.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] This multi-station pneumatic sample transfer workstation employs a multi-stage buffering mechanism. This is achieved through a combination of a first spring and a support block for primary longitudinal buffering, a second spring and a locking block for secondary lateral buffering, and a rubber pad on the outside of the locking block for tertiary residual impact absorption. This multi-stage buffering effectively prevents sample damage from impacts. An infrared beam sensor and an electromagnet work together to push the locking block outwards when the transfer cylinder approaches, and a second spring pulls the locking block back to its original position after the transfer cylinder is removed, preventing rigid collisions between the transfer cylinder and components, reducing wear, and improving equipment safety. A T-shaped limit block and a limit groove provide precise guidance for the support block's movement, and the curved design of the rubber pad enhances clamping friction, ensuring stable and reliable buffering and improving clamping stability. The infrared beam sensor acts as a start switch, triggering coordinated action of related components to achieve automated buffering control and improve work efficiency. The sponge pad inside the workstation's casing and the buffering mechanism provide double protection, enhancing equipment safety. All of this stems from the workstation's ability to buffer the pneumatic transfer cylinder. Attached Figure Description

Detailed Implementation
[0019] 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.
[0020] Please see Figure 1-4 A multi-station pneumatic sample transfer workstation in this embodiment includes a base 1, a workstation shell 2 fixedly connected to the top of the base 1, a controller 3 disposed on the outside of the workstation shell 2, a magnetic door 4 hinged to the outside of the workstation shell 2, a handle 401 fixedly connected to the outside of the magnetic door 4, and a buffer mechanism 5 disposed inside the workstation shell 2.
[0021] The buffer mechanism 5 includes a support plate 501, which is fixedly connected to the inner wall of the workstation housing 2. A first spring 502 is fixedly connected to the top of the support plate 501. A support block 503 is fixedly connected to the top of the first spring 502. A snap-fit box 506 is fixedly connected to the top of the support block 503. A magnetic block 507 is provided inside the snap-fit box 506. A snap-fit block 508 is fixedly connected to one end of the magnetic block 507. A second spring 512 is provided outside the magnetic block 507.
[0022] The magnetic block 507 extends through the second spring 512 to the outside of the latch box 506. One end of the second spring 512 is fixedly connected to the inner wall of the latch box 506, and the other end is fixedly connected to the latch block 508. This structure makes the second spring 512 the power source for the reset of the latch block 508. When the electromagnet 511 is energized and pushes out the latch block 508, the second spring 512 is stretched synchronously. After the transmission cylinder is removed, the latch block 508, which has lost the electromagnetic force, quickly resets under the tension of the second spring 512, preventing the subsequent pneumatic transmission cylinder from colliding with the latch block 508 when it enters. It also prepares for the next clamping and ensures the continuity of the buffering process.
[0023] An electromagnet 511 is fixedly connected to the top of the support block 503. The electromagnet 511 is located to the left of the magnetic block 507. When the infrared beam sensor 510 detects that the pneumatic transmission tube is approaching, the controller 3 triggers the electromagnet 511 to be energized. Using the principle of like poles repulsion, the controller 3 pushes the magnetic block 507 and moves the clamping block 508 outward, providing sufficient space for the transmission tube to enter and avoiding a rigid collision between the transmission tube and the clamping block 508. When the transmission tube is stable, the electromagnet 511 is de-energized, and the clamping block 508 resets under the tension of the second spring 512 to clamp the transmission tube, completing the buffering process of flexible clamping.
[0024] A support plate 501 is fixedly connected to the left side of the support block 503. A limiting groove 505 is provided on the inner wall of the workstation housing 2. The left side of the support plate 501 is T-shaped and is engaged with the inner wall of the limiting groove 505. The cooperation between the T-shaped limiting block 504 and the limiting groove 505 provides precise guidance for the up and down movement of the support block 503. When the pneumatic transmission cylinder enters the buckle box 506 and generates a downward impact force, the support block 503 compresses the first spring 502 and moves downward. The limiting block 504 slides synchronously along the limiting groove 505 to prevent the support block 503 from shifting or shaking, ensuring that the first spring 502 is evenly stressed, stably absorbing impact energy, and improving the overall stability of the buffer mechanism 5.
[0025] The external fixed connection of the clamping block 508 is a rubber pad 509. The side of the rubber pad 509 that contacts the pneumatic transmission cylinder is arc-shaped. The arc-shaped design allows it to fit tightly against the outer wall of the pneumatic transmission cylinder, increasing the contact area. The elastic properties of the rubber can further absorb the impact force when the clamping block 508 resets, avoiding damage to the transmission cylinder caused by rigid clamping. At the same time, it enhances the clamping friction and prevents the transmission cylinder from shaking during the buffering process.
[0026] A sponge pad 7 is fixedly connected to the inner bottom wall of the workstation housing 2, and an infrared beam sensor 510 is fixedly connected to the top of the buckle box 506. The infrared beam sensor 510 is the "start switch" of the buffer mechanism 5. When the pneumatic transmission tube is detected to be close, it immediately sends a signal to the controller 3, triggering the electromagnet 511 and other components to work together to ensure that the buffer mechanism is activated in advance. The sponge pad 7 serves as an emergency protection. If the transmission tube is accidentally dropped, it can absorb the impact force through its own elasticity to prevent the transmission tube from directly hitting the bottom of the workstation housing 2 and causing damage, thus forming a double buffer protection.
[0027] During implementation, multiple sets of pneumatic transmission pipes are installed on the top of the workstation housing 2. The bottom outlet of the pneumatic transmission pipe is located at the top of the buffer mechanism 5. During implementation, the pneumatic transmission cylinder is transported through the pneumatic transmission pipe on the top of the workstation housing 2 to the middle position of the two symmetrically distributed buffer mechanisms 5.
[0028] In implementation, the controller 3 is equipped with a microcontroller. The microcontroller is electrically connected to all electronic components in this patent through wires, so that the electromagnet 511 can be activated when the infrared beam sensor 510 detects the transmission tube.
[0029] When implementing this procedure, please follow these steps:
[0030] 1) When the pneumatic transmission cylinder approaches the latch box 506 at the target station, the infrared beam sensor 510 on the top of the latch box 506 detects the transmission cylinder and immediately sends a signal to the controller 3. The controller 3 triggers the electromagnet 511 on the top of the support block 503 to be energized. The electromagnet 511 generates a magnetic field with the same pole as the magnetic block 507, which pushes the magnetic block 507 to move the latch block 508 outward, and the second spring 512 is stretched.
[0031] 2) Then, after the pneumatic transmission cylinder enters the snap-fit box 506, it moves downward under its own weight and the thrust of the airflow, squeezing the support block 503. This causes the support block 503 to compress the first spring 502 and move downward. The T-shaped limit block 504 slides synchronously along the limit groove 505 to ensure stable movement. Subsequently, the controller 3 controls the electromagnet 511 to be de-energized. Under the pulling force of the second spring 512, the snap-fit block 508 resets, and its external rubber pad 509 tightly adheres to the transmission cylinder, flexibly clamping the transmission cylinder and achieving buffering.
[0032] 3) Finally, open the magnetic door 4 using handle 401 and manually remove the pneumatic transmission cylinder from the latch box 506. After removal, the second spring 512 pulls the latch block 508 back to reset, waiting for the next transmission.
[0033] In summary, this multi-station pneumatic sample transfer workstation achieves multi-stage buffering for the pneumatic transfer cylinder by using a combination of a first spring 502 and a support block 503 to provide primary longitudinal buffering, a secondary lateral buffering by the connection structure between a second spring 512 and a locking block 508, and a tertiary residual impact absorption by a rubber pad 509 on the outside of the locking block 508. This effectively prevents sample damage due to impact. Furthermore, by utilizing the cooperation of an infrared beam sensor 510 and an electromagnet 511, the locking block 508 is pushed outward when the transfer cylinder approaches, and after the transfer cylinder is removed, the second spring 512 pulls the locking block 508 back to its original position, preventing damage during transfer. Rigid collision between the cylinder and components reduces component wear and improves equipment safety. The T-shaped limit block 504 and the limit groove 505 work together to provide precise guidance for the movement of the support block 503. Combined with the arc design of the rubber pad 509, the clamping friction is enhanced, ensuring a stable and reliable buffering process and improving clamping stability. The infrared beam sensor 510 acts as a start switch, triggering the coordinated action of related components to achieve automated buffering control and improve work efficiency. The sponge pad 7 inside the workstation housing 2 and the buffering mechanism 5 form a double protection, enhancing equipment safety. All of this stems from the fact that this workstation has the advantage of being able to buffer the pneumatic transmission cylinder.
