[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, a combined cover opening device includes a first carrier 1 that is driven to slide along a direction, a first electric push rod 2 is symmetrically arranged on a first side surface of the first carrier 1, and an output end of the first electric push rod 2 is connected to a second carrier 3 arranged on a second side surface of the first carrier 1;

[0031] A plurality of perfusion heads 4 arranged in a linear array are fixedly mounted on the second carrier 3;

[0032] The first carrier 1 is provided with a flip cover mechanism 5 extending from the waist groove on the second carrier 3. The flip cover mechanism 5 includes a movably assembled actuator 51. A latching tongue 52 is rotatably provided in a notch at the end of the actuator 51. The latching tongue 52 is pushed by a blocking spring 53 provided in the notch to maintain horizontality.

[0033] Specifically, a second electric push rod 9 is centrally mounted on the top of the housing 7. The output end of the second electric push rod 9 is fixedly connected to the first carrier 1 located inside the housing 7. The electric slide module 6 is mounted on the housing 7, and the movement direction of the first carrier 1 is perpendicular to the movement direction of the upper slide.

[0034] The slide of the electric slide module 6 is provided with a quick clamp, and other well-known clamping structures are used to fix the test tube rack placed on the slide, which belongs to public technology and will not be described in detail.

[0035] The filling head 4 is externally connected to a liquid supply device, so that liquid can be injected into the opened test tube through the filling head 4 .

[0036] Furthermore, combined Figure 1 It can be seen that four guide wheels 8 with locking function are installed at the bottom of the casing 7.

[0037] In the above technology, when the first carrier 1 moves down to a predetermined height, the lid of the test tube will be locked in the tongue 52. At this time, the actuator 51 moves so that the lid is flipped open and avoided under the locking of the tongue 52. At this time, the first electric push rod 2 drives the second carrier 3 to move down the perfusion head 4 and extend it into the test tube port to inject liquid.

[0038] It should be noted that the above steps require the cooperation of electronic sensors. The specific electronic component settings and control procedures are common knowledge among those skilled in the art, so the electronic component settings and procedures are not described in detail.

[0039] As a further embodiment of the present invention, a rounded rectangular groove is provided on the tongue 52, and an axis rod is provided in the notch and is located in the rounded rectangular groove. Under the action of the blocking spring 53, the axis rod is maintained at one end of the rounded rectangular groove so that the tongue 52 is driven to move relative to the outside of the notch.

[0040] Furthermore, the outer side surface of the latch tongue 52 is an inclined surface.

[0041] Specific, combined Figure 3 It can be seen that the injection head 4 in the embodiment is arranged above the actuator 51 and distributed close to the end where the tongue 52 is located.

[0042] Furthermore, when the first carrier 1 moves down to a predetermined height, the cover of the test tube will contact the inclined surface and then slide down so that the latch 52 can move downward. Figure 3The position shown is a reference, and the cover moves to the right side, and the cover is pulled into the latch 52 under the action of the blocking spring 53. At this time, when the latch 52 moves and resets, the switch will be touched, thereby continuing to the next step.

[0043] As a further embodiment of the present invention, the card flip mechanism 5 includes a guide rail member 54 slidably assembled on the first carrier 1, and a first z-shaped groove 541 and a second z-shaped groove 542 arranged vertically are provided on the guide rail member 54, and the outer walls on both sides of the actuator 51 are provided with short shaft members sliding in the first z-shaped groove 541 and the second z-shaped groove 542.

[0044] Furthermore, the second Z-shaped groove 542 and the first Z-shaped groove 541 are divided into a high portion and a low portion according to their structures, wherein:

[0045] The end of the high portion of the second Z-shaped groove 542 is open.

[0046] Specifically, the motor 55 is fixedly mounted on the first carrier 1 in the embodiment, and the transmission shaft fixedly connected to the output end of the motor 55 is also mounted on the first carrier 1 through a bearing seat. When the touch switch is punished, the second electric push rod 9 stops running.

[0047] At this time, the motor 55 runs to drive the transmission shaft to rotate, so that the transmission shaft reels in the pulling rope 57. The pulling rope 57 here is connected to the side wall of the end of the tongue 52 on the actuator 51. When it is retracted, the actuator 51 moves along the low part toward the high part. When it reaches the end of the high part, the short shaft part rotates with the end of the high part of the first Z-shaped groove 541 as the origin. The short shaft part moves out from the opening at the end of the high part of the second Z-shaped groove 542. At this time, the actuator 51 deflects to avoid the downward movement path of the injection head 4, that is, Figure 5 shown.

[0048] It should be noted that, after the actuator 51 is deflected by a predetermined angle, the latch 52 cannot hook onto the lid of the test tube, and the two are in a contact hook relationship.

[0049] When the predetermined angle is reached, the motor 55 stops running, and the first electric push rod 2 drives the second platform 3 to move the perfusion head 4 downward and extend it into the test tube port to inject liquid. After the predetermined liquid is injected, the first electric push rod 2 drives the perfusion head 4 to reset, and the second electric push rod 9 drives the first platform 1 to reset at the same time, and the motor 55 runs to make the actuator 51 return to Figure 3 Status shown.

[0050] As another embodiment further provided by the present invention, the flip mechanism 5 includes:

[0051] A motor 55 fixedly mounted on the first carrier 1;

[0052] The transmission shaft is rotatably arranged and fixedly connected to the output end of the motor 55 , and a plurality of transmission gears 56 arranged at intervals are fixedly mounted thereon. The transmission gears 56 mesh with the toothed plates on the guide rail member 54 .

[0053] Furthermore, a pulling rope 57 fixedly connected to the actuator 51 is eccentrically provided on the end surface of the transmission gear 56 in the above embodiment.

[0054] Specifically, the motor 55 rotates, driving the transmission shaft to rotate, causing the transmission gear 56 to reel in the pull rope 57. This retraction causes the actuator 51 to move along the lower portion toward the upper portion. At the end of the upper portion, the short shaft rotates with the upper end of the first Z-shaped slot 541 as its origin, moving out of the opening at the upper end of the second Z-shaped slot 542. During this movement from the lower portion toward the upper portion, the transmission gear 56 also drives the guide rail 54 upward to coordinate the sliding and deflection of the actuator 51.

[0055] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
