Description

Technical Field

[0001] The invention relates to the field of cell culture, in particular to a pipeline loading automatic identification pinch valve system. Background Art

[0002] The technology of the present invention is applied in the industrial and medical fields, especially in the field of cell culture in biological medicine. Cell culture refers to a method of simulating the in vivo environment (sterility, suitable temperature, pH and certain nutritional conditions, etc.) in vitro to enable it to survive, grow, reproduce and maintain its main structure and function. Cell culture technology is an important and commonly used technology in cell biology research methods. Through cell culture, a large number of cells can be obtained, and cell signal transduction, cell anabolism, cell growth and proliferation, etc. can be studied. In the process of cell culture, it is necessary to complete the processes of fluid replenishment, fluid drainage, replacement, and disinfection; these processes are required to be carried out in a closed and sterile environment, and the hose is shut off or the hose is loosened by squeezing the clamp valve to achieve smooth pipeline, and cooperate with other actuators to complete the functions of fluid replenishment, fluid drainage, replacement, and disinfection to avoid contamination of the controlled liquid.

[0003] The existing pinch valves on the market do not have the function of automatic recognition of pipeline loading, and the pipeline loading is side loading; pinch valves without automatic recognition of pipeline loading have potential risks such as pipeline failure due to improper operation and pipeline leakage; side pipeline loading is inconvenient and requires a large operating space. In the cell culture process, the culture technology is complex and the culture cycle is long. The above abnormal situations in production often cause significant losses. In order to improve production efficiency, most companies will use fully automatic or semi-automatic production equipment. When there is frequent loading and removal of pipelines, it is more likely to cause problems if people are relied on to judge whether the pipelines are loaded in place.

[0004] In summary, there is an urgent need for a pinch valve that can identify the loading status of the hose and the pipeline loading direction is not on the side. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a pipe loading automatic identification pinch valve system. The identification mechanism of the present invention can automatically detect the loading status of the hose, and at the same time cooperate with the circuit logic judgment, and can remind whether the pipe loading is correct in the operation interface and program, so as to prevent the occurrence of abnormal pipe loading and cause unnecessary losses.

[0006] The present invention provides a pipeline loading automatic identification pinch valve system, comprising a valve body and a valve head arranged at the top of the valve body, wherein a first hose groove with a slotted direction located at the top is penetrated in the valve head, and the first hose groove is suitable for placing a hose.

[0007] In a feasible embodiment, the valve head is further provided with a pinch valve slide groove which is transversely perpendicular to the first hose groove, and the pinch valve can be slidably arranged in the pinch valve slide groove. The pinch valve slide groove includes a first slide groove section and a second slide groove section located on both sides of the first hose groove, and a first abutment is arranged in the first slide groove section. The pinch valve includes a front valve body, a second hose groove which is transversely perpendicular to the pinch valve and has a groove direction located at the top, and a rear valve body in sequence. The front valve body also includes a first abutment groove which is connected to the second hose groove, and the rear valve body also includes a second abutment protruding in the direction of the second hose groove.

[0008] In a feasible embodiment, the first hose groove includes, from top to bottom, a first hose groove upper part, a first hose groove middle part and a first hose groove lower part; the cross-sectional width of the first hose groove middle part is smaller than the cross-sectional width of the hose, and the cross-sectional width of the lower part of the first hose groove matches the cross-sectional width of the hose.

[0009] In a feasible implementation manner, the first abutting member and the second abutting member are both in the shape of a cylinder, and / or the first abutting member and the second abutting member are of the same size.

[0010] In a feasible implementation manner, a pinch valve driving member is further provided in the valve body, and the pinch valve driving member drives the pinch valve to move along the pinch valve sliding groove.

[0011] In a feasible embodiment, the pinch valve driving element is selected from any one of a stepping motor, a DC reduction motor or a servo motor.

[0013] In a feasible implementation manner, the actuator is connected to the identification control board and the pinch valve driving member through a board card or a wiring harness.

[0058] Embodiment 1

[0059] The present invention provides a pipe loading automatic identification pinch valve system, referring to Figure 1 and Figure 2 , including a valve body 1 and a valve head 2 arranged on the top of the valve body 1. The valve body 1 and the valve head 2 are not completely isolated, and there are some connecting channels inside for wiring. Preferably, the valve body 1 and the valve head 2 are integrally formed. The valve head 2 is provided with a first hose groove 21 with a groove direction located at the top. The first hose groove 21 is suitable for placing a hose. The valve head 2 is also provided with a clamp valve 3 arranged transversely and perpendicular to the first hose groove 21. The clamp valve 3 is used to squeeze the hose transversely and close part of the passage of the first hose groove 21 to achieve the effect of shutting off the hose. Figure 2The valve body 1 is also provided with an identification mechanism 4, which includes an identification control board 42 and an identification switch 41 disposed on the identification control board 42 and connected through a circuit, and the sensing end of the identification switch 41 is disposed in the first hose groove 21. In a specific embodiment, the identification switch 41 is selected from any one of a mechanical micro switch, a photoelectric switch or a capacitive switch. Preferably, the identification switch 41 is a mechanical micro switch. Generally speaking, the identification switch 41 is welded to the identification control board 42. Continue to refer to Figure 2 , the valve body 1 is provided with an actuator 5, which is connected to the identification control board 42 and the clamp valve 3 through a circuit drive. In a specific embodiment, the actuator 5 is connected to the identification control board 42 and the clamp valve driver through a board card or a wiring harness. As a supplement, the actuator 5 can be externally connected to the host computer to display the status of the clamp valve 3 and the identification mechanism 4 in the host computer, which is convenient for monitoring the working status of the pipeline loading automatic identification clamp valve, making the pipeline loading automatic identification clamp valve more systematic and convenient for operators to operate. In addition, an indicator light 22 can also be provided on the identification valve head 2, and the indicator light 22 is connected to the host computer through a circuit. Under normal circumstances, the indicator light 22 has several states: 1) When the first tank body 21 is unloaded, the indicator light 22 may not light up; 2) When the first tank body 21 is loaded with a hose, the indicator light 22 may display a color; 3) When the hose is turned off by the clamp valve 3, the indicator light 22 may display another color. The indicator light 22 can make it easier for operators to monitor the working status of the current self-identification valve. Through the above-mentioned arrangement, the present invention can automatically identify the loading status of the first hose groove 21, effectively avoiding the misoperation of the clamping valve 3 in the no-load state, and improving the production efficiency while ensuring production safety. At the same time, the first hose groove 21 of the present invention is opened upward, avoiding the problem of small side space and difficult operation when disassembling and assembling the hose, and making it easier to disassemble and assemble the hose.

[0060] Further, see Figure 3 The valve head 2 is also provided with a pinch valve slide groove 6 which is transversely perpendicular to the first hose groove 21. The pinch valve 3 can slide along the pinch valve slide groove 6. The first hose groove 21 and the pinch valve slide groove 6 form a cross-shaped through groove. The pinch valve slide groove 6 includes a first slide groove section 61 and a second slide groove section 62 located on both sides of the first hose groove 21. Figure 4 and Figure 5 As shown, one end of the first chute section 61 is connected to the external space to ensure that the pinch valve 3 can be partially suspended in the external space when it moves outward along the pinch valve chute 6, so that the pinch valve 3 has enough movement space to shut off the hose. Figure 4 A first abutting member 61.1 is disposed in the first slide groove section 61. The first abutting member 61.1 does not move with any structure. Preferably, the first abutting member 61.1 is cylindrical. Figure 6The pinch valve 3 includes a front valve body 31, a second hose groove 32 which is transversely perpendicular to the pinch valve 3 and has a groove direction at the top, and a rear valve body 33. Preferably, the pinch valve 3 is integrally formed. Figure 6 , the front valve body 31 further includes a first abutment groove 32.1 connected to the second hose groove 32, and the rear valve body 33 further includes a second abutment 33.1 protruding toward the second hose groove 32, preferably, the second abutment 33.1 is cylindrical. Specifically, the first abutment groove 32.1 is an L-shaped groove, including a longitudinal groove and a transverse groove that are connected to each other, the longitudinal groove is formed by the front valve body 31 being recessed toward the inside of the front valve body 31, and the transverse groove is formed by the second hose groove 32 being recessed toward the inside of the second hose groove 32. The shape of the longitudinal groove should match the first abutment 61.1 to ensure that the longitudinal groove can abut the first abutment 61.1 when the pinch valve 3 moves inward, so as to prevent the pinch valve 3 from over-extending. The cross-sectional shape of the transverse groove should be a straight-line extension of the cross-sectional shape of the first abutment 61.1, and the extension length of the transverse groove should be sufficient to ensure that the second abutment 33.1 and the first abutment 61.1 can be abutted against each other by the clamping valve 3 within the moving distance, thereby shutting off the hose.

[0061] In addition, when the hose is turned off, the pinch valve 3 slides outward along the pinch valve slide groove 6, and the second abutting piece 33.1 gradually approaches the first abutting piece 61.1 and squeezes the hose until the second abutting piece 33.1 approaches or directly abuts the first abutting piece 61.1, at which time the first hose groove 21 and the second hose groove 32 are separated from each other. When the hose is released, the pinch valve 3 slides inward along the pinch valve slide groove 6, and the second abutting piece 33.1 gradually moves away from the first abutting piece 61.1 and releases the hose until the first abutting piece groove 32.1 abuts the first abutting piece 33.1, at which time the first hose groove 21 and the second hose groove 32 should overlap with each other and be used as the same channel.

[0062] Further, see Figure 7 The first hose groove 21 includes, from top to bottom, a first hose groove upper portion 21.1, a first hose groove middle portion 21.2, and a first hose groove lower portion 21.3. The cross-sectional width of the first hose groove middle portion 21.2 is smaller than the cross-sectional width of the hose, and the cross-sectional width of the first hose groove lower portion 21.3 matches the cross-sectional width of the hose. In addition, when the hose is placed in the first hose groove lower portion 21.3, since the cross-sectional width of the first hose groove middle portion 21.2 is smaller than the cross-sectional width of the hose, it is difficult for the hose to slip out upwards without external force intervention, so the hose is relatively fixed at the position of the first hose groove lower portion 21.3, thereby improving the stability and safety of the device when in use.

[0063] In a specific embodiment, the valve body 1 is further provided with a pinch valve driver, which drives the pinch valve 3 to move along the pinch valve slide 6. Further, the pinch valve driver is selected from any one of a stepper motor, a DC reduction motor or a servo motor, and preferably, the pinch valve driver is a servo motor. In another specific embodiment, the pinch valve 3 is selected from any one of an electromagnetic pinch valve, an electric pinch valve or a pneumatic pinch valve, and preferably, the pinch valve 3 is an electromagnetic pinch valve.

[0064] The present invention also provides a method for using the pipeline loading automatic identification pinch valve system, which at least includes the following steps:

[0065] Step 1) Place the hose in the first hose groove 21. Further, place the hose in the lower part 21.3 of the first hose groove;

[0066] Step 2) The hose is pressed to the sensing end of the identification switch 41, and the electrical signal generated in the identification switch 41 is captured by the identification control board 42, which processes the signal and forwards it to the actuator 5. Furthermore, when the identification switch 41 is not pressed, it maintains a low level state, and when it is pressed by the hose, it will continuously output a high level. When the identification control board 42 captures the continuous high level, it means that the hose has been placed in the first hose groove 21;

[0067] Step 3) The actuator 5 sends a command to the pinch valve 3 to shut off or release the hose. Figure 4 and Figure 5 As shown, the pinch valve 3 moves along the pinch valve slide groove 6 toward the outside of the valve head 2. During the movement, the second abutting member 33.1 continuously squeezes the hose until the second abutting member 33.1 abuts against or nearly abuts against the first abutting member 61.1. At this time, the hose is clamped between the first abutting member 61.1 and the second abutting member 33.1, so that the liquid cannot flow. Figure 8 and Fig. 9 As shown, when released, the pinch valve 3 moves along the pinch valve slide groove 6 toward the inside of the valve head 2. During the movement, the second abutment 33.1 gradually moves away from the first abutment 33.1 until the first abutment groove 32.1 abuts or is close to abutting the first abutment 61.1. At this time, the second hose groove 32 and the first hose groove 21 overlap with each other and form a hose channel, so that the hose is released and the liquid in the hose can flow smoothly through the hose.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
