DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model.

[0039] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0041] As mentioned in the background technology, in the existing technical solutions, the way to open the multi-tube (such as eight-tube) is basically to open the cover manually, but the manual opening method is prone to splashing during the opening process, and also increases the labor intensity.

[0042] In some cases, although manual lid openers are used for lid opening, the requirements for the shape of the eight-tube strip are relatively simple. For example, in the scenario where the gap between the eight-tube strip cover and the eight-tube strip is small, manual lid opening is difficult and it is difficult to align the gap, which affects the efficiency of lid opening. In addition, after opening the eight-tube strip cover and adding reagents or samples to the eight-tube strip, it is usually necessary to tightly close the eight-tube strip cover and the eight-tube strip again. The manual lid closing method used in the prior art is laborious and requires manual confirmation of whether each tube body in the eight-tube strip is tightly closed, which increases the labor intensity and reduces the efficiency of lid closing.

[0043] In view of this, please refer to Figure 1-Figure 8 The cover opening device provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0044] An embodiment of the utility model provides a cover opening device, which includes a driving member 11, a clamping member and a first cover opening member 133, wherein the clamping member is connected to the driving member 11, and the first cover opening member 133 is connected to the clamping member.

[0045] Among them, the driving member 11 is used to drive the clamping member to move, so that the edge of the first opening member 133 is inserted into the gap between the multi-tube 211 and the multi-tube cover 212, and the multi-tube 211 and the multi-tube cover 212 are propped open to separate the multi-tube 211 and the multi-tube cover 212 from each other, thereby replacing the manual opening method.

[0046] At the same time, the edge of the first opening member 133 is driven by the clamping member to insert into the gap between the multi-tube 211 and the multi-tube cover 212, so as to open the multi-tube 211 and the multi-tube cover 212, and the opening process is smooth, avoiding the risk of splashing during the opening process.

[0047] In addition, it should be noted that in order to smoothly separate the multi-tube 211 and the multi-tube cover 212 from each other, the first cover opening member 133 is provided with a plurality of avoidance grooves 1331. At this time, the first cover opening member 133 has a tooth-like structure.

[0048] The number of the avoidance grooves 1331 may correspond to the number of tube bodies of the multi-tube 211. For example, in the present embodiment, the multi-tube 211 is an eight-tube, and the multi-tube cover 212 is an eight-tube cover adapted for the eight-tube. The number of the avoidance grooves 1331 is eight. The avoidance grooves 1331 may prevent the first cover opening member 133 and the multi-tube cover 212 from interfering with each other and affecting the cover opening process during the cover opening process of the cover opening device. At the same time, it is also convenient to clamp the multi-tube cover 212 through the avoidance grooves 1331.

[0049] Specifically, in this embodiment, the driving member 11 can use an electric clamp, and the clamping member includes a first clamping plate 13 and a second clamping plate. The first clamping plate 13 and the second clamping plate are both connected to the clamping claw on the driving member 11. The driving member 11 can drive the first clamping plate 13 and the second clamping plate to move closer to or away from each other.

[0050] The first clamping plate 13 is provided with a first clamping plate mounting hole 131 , so that a fastener (such as a screw) can penetrate the clamping claw on the driving member 11 and the first clamping plate mounting hole 131 to achieve connection between the first clamping plate 13 and the clamping claw on the driving member 11 .

[0051] At the same time, in this embodiment, the first clamp 13 and the second clamp have the same structure, that is, a second clamp mounting hole is provided on the second clamp, so that a fastener (such as a screw) can be passed through the clamp on the driving member 11 and the second clamp mounting hole to realize the connection between the second clamp and the clamp on the driving member 11.

[0052] Among them, the first cover opening member 133 is connected to the first clamping plate 13, and the driving member 11 is used to drive the first clamping plate 13 and the second clamping plate to approach each other, so that the edge of the first cover opening member 133 is inserted into the gap between the multi-tube 211 and the multi-tube cover 212, and the multi-tube 211 and the multi-tube cover 212 are propped open to separate the multi-tube 211 and the multi-tube cover 212 from each other.

[0053] In this embodiment, the cover opening device further comprises a second cover opening member, the second cover opening member is connected to the second clamping plate, the first cover opening member 133 has a first guiding inclined surface 134, and the second cover opening member has a second guiding inclined surface.

[0054] Among them, the driving member 11 is used to drive the first clamping plate 13 and the second clamping plate to approach each other, so that the edge of the first opening cover member 133 and the edge of the second opening cover member are inserted into the gap between the multi-tube 211 and the multi-tube cover 212, the first guide slope 134 slides relative to the multi-tube 211, and the second guide slope slides relative to the multi-tube 211, to open the multi-tube 211 and the multi-tube cover 212, so that the multi-tube 211 and the multi-tube cover 212 are separated from each other.

[0055] In some embodiments, the first guide bevel 134 may slide relative to the multi-tube cover 212 and the second guide bevel may slide relative to the multi-tube cover 212, or the first guide bevel 134 may slide relative to the multi-tube cover 212 and the second guide bevel may slide relative to the multi-tube 211, or the first guide bevel 134 may slide relative to the multi-tube 211 and the second guide bevel may slide relative to the multi-tube cover 212.

[0056] The structure of the second cover opening member may refer to the description of the first cover opening member 133, which will not be repeated here.

[0057] It should be noted that, when the first splint 13 is connected to the first cover-opening piece 133 and the second splint is not connected to the second cover-opening piece, at this time, the edge of the first cover-opening piece 133 is inserted into the gap between the multi-tube 211 and the multi-tube cover 212, and at the same time, the second splint abuts the multi-tube 211 or the multi-tube cover 212. Of course, the second splint can also abut the multi-tube 211 and the multi-tube cover 212 at the same time to achieve the separation of the multi-tube 211 and the multi-tube cover 212 from each other.

[0058] In order to facilitate the precise insertion of the first cover opening piece 133 and the second cover opening piece into the gap between the multi-tube 211 and the multi-tube cover 212, the cover opening device also includes a pressing plate 12, which is connected to the first clamping plate 13 and the second clamping plate at the same time, and is used to squeeze the multi-tube cover 212.

[0059] Among them, the lower end surface of the pressing plate is a plane, and the height of the lower end surface of the pressing plate is greater than the height of the edge of the first opening cover part. The lower end surface of the pressing plate is used to make the edge of the first opening cover part insert into the gap between the multi-tube and the multi-tube cover when the multi-tube cover is squeezed and the driving part is used to drive the clamping part to move.

[0060] In this embodiment, the height of the edge of the first cover opening member and the height of the edge of the second cover opening member are at the same height.

[0061] Specifically, the cover opening device also includes two first guide shafts 14, two second guide shafts, two first elastic members and two second elastic members 15, one end of each first guide shaft 14 is connected to the pressure plate 12, and the other end of each first guide shaft 14 is slidably connected to the second clamping plate.

[0062] One end of each second guide shaft is connected to the pressure plate 12, and each second guide shaft is slidably connected to the first clamping plate 13, the two first elastic members are used to elastically abut the pressure plate 12 and the second clamping plate at the same time, and the two second elastic members 15 are used to elastically abut the pressure plate 12 and the first clamping plate 13 at the same time.

[0063] In this embodiment, both the first elastic member and the second elastic member 15 are springs. Each first elastic member is sleeved on each second guide shaft, and each second elastic member 15 is sleeved on each first guide shaft 14 .

[0064] It should be noted that the second clamping plate is provided with two second clamping plate guide holes, and the other end of each first guide shaft 14 can be slidably passed through each second clamping plate guide hole, and the first clamping plate 13 is provided with two first clamping plate guide holes 132, and the other end of each second guide shaft can be slidably passed through each first clamping plate guide hole 132.

[0065] It is easy to understand that the first guide shaft and the second guide shaft can be integrally formed to form an axis that passes through the pressure plate 12. The first elastic member and the second elastic member 15 can ensure that the pressure plate 12 is always in the middle position between the first clamping plate and the second clamping plate, ensuring that the pressure plate 12 is always directly above the multi-tube cover 212 when the multi-tube cover 212 is clamped. The first elastic member and the second elastic member 15 prevent the pressure plate 12 from sliding arbitrarily relative to the first guide shaft or the second guide shaft, resulting in position displacement.

[0066] It should be noted that, in the present embodiment, the driving member 11 , the clamping member, the pressing plate 12 , the first cover opening member 133 and the second cover opening member constitute the clamping jaw cover opening mechanism 1 .

[0067] In order to facilitate the pressing plate 12 to press the multi-tube cover 212, the cover opening device also includes a moving mechanism, which is connected to the pressing plate 12 or the driving member 11, and is used to drive the pressing plate 12 to move so that the pressing plate 12 squeezes the multi-tube cover 212.

[0068] For example, the moving mechanism can be a pneumatic cylinder or an oil cylinder, and the moving mechanism is connected to the driving member 11 to drive the driving member 11 to move downward, so that the pressure plate 12 can press down the multi-tube cover 212. Of course, the moving mechanism can also be connected to the pressure plate 12 to drive the pressure plate 12 to move downward, so that the pressure plate 12 can press down the multi-tube cover 212.

[0069] In addition, the cover opening device also includes a placing piece 22, a supporting piece 23 and a third elastic piece 231. The supporting piece 23 is provided with a receiving groove, and the placing piece 22 can be slidably matched with the receiving groove. The third elastic piece 231 is arranged in the receiving groove and is used to elastically abut the placing piece 22. The placing piece 22 is used to place the multi-tube 211 and to limit the multi-tube 211.

[0070] The placement piece 22 is provided with a plurality of limiting grooves, the number of which corresponds to the number of tube bodies of the multi-tube 211. That is to say, when the multi-tube 211 is an eight-tube, the number of limiting grooves is eight, and each tube body of the multi-tube 211 fits in the corresponding limiting groove, which can play a limiting role for the multi-tube 211.

[0071] The cover opening device further includes a supporting step 233 , which is disposed in the receiving groove and is used to support the placement member 22 .

[0072] In this embodiment, there are multiple third elastic members 231, and the third elastic members 231 can be compression springs. A plurality of spring guide columns 232 are provided in the accommodating groove of the supporting member 23, and each elastic member is respectively sleeved on each spring guide column 232. It should be noted that, in this embodiment, the support step 233, the spring guide column 232 and the supporting member 23 can be integrally formed.

[0073] According to a cover opening device provided in this embodiment, the working principle of the cover opening device is as follows:

[0074] Please refer to Figure 7 and Figure 8 , the placement member 22 is matched in the receiving groove of the bearing member 23, and the multi-tube assembly 21 (i.e., the eight-tube assembly) is placed in the placement member 22, and the moving mechanism drives the pressing plate 12 to move downward to abut against the upper surface of the multi-tube cover 212, so that the upper surface of the multi-tube cover 212 is entirely against the lower end surface of the pressing plate 12. At this time, the third elastic member 231 in the receiving groove provides elastic support for the placement member 22. Specifically, the multi-tube cover 212 is usually made of plastic material, which is easy to deform, resulting in uneven gaps at different positions between the multi-tube 211 and the multi-tube cover 212. The pressing plate 12 presses the multi-tube cover 212 so that the upper surface of the multi-tube cover 212 is in close contact with the plane of the lower end surface of the pressing plate 12, thereby correcting the deformation of the multi-tube cover 212, so that the gaps at different positions between the multi-tube 211 and the multi-tube cover 212 are consistent.

[0075] Furthermore, the driving member 11 drives the first clamping plate 13 and the second clamping plate to approach each other, so that the edge of the first opening cover member 133 and the edge of the second opening cover member are inserted into the gap between the multi-tube 211 and the multi-tube cover 212. During this process, the upper surface of the multi-tube cover 212 remains in close contact with the lower end surface of the pressure plate 12, and the third elastic member 231 in the accommodating groove is compressed, and the gap distance between the multi-tube 211 and the multi-tube cover 212 increases until the multi-tube 211 and the multi-tube cover 212 are separated from each other.

[0076] Since the dimensions of the pressing plate 12 and the first cover-opening component 133 and the second cover-opening component can be precisely controlled to ensure that the first cover-opening component 133 and the second cover-opening component can be precisely inserted into the gap between the eight-link tube and the eight-link tube cover, when starting to open the cover, the first guide slope 134 slides relative to the multi-link tube 211, and the second guide slope slides relative to the multi-link tube 211 to prop open the multi-link tube 211 and the multi-link tube cover 212, and the eight-link tube and the eight-link tube cover are separated by relying on the guidance of the first guide slope 134 and the second guide slope to complete the cover opening process.

[0077] Specifically, since the dimensions of the pressing plate 12, the first cover opening member 133 and the second cover opening member can be precisely controlled, and the height of the lower end surface of the pressing plate is greater than the height of the edge of the first cover opening member, the distance from the lower end surface of the pressing plate to the edge of the first cover opening member in the vertical direction can be a determined preset distance, and the preset distance can be set when manufacturing the cover opening device. Specifically, the preset distance can be equal to the distance from the upper surface of the multi-tube cover to the gap between the multi-tube and the multi-tube cover in the vertical direction. In this way, it can be ensured that the lower end surface of the pressing plate is squeezed on the upper surface of the multi-tube cover, and at the same time, the driving member drives the clamping member to move so that the edge of the first cover opening member and the edge of the second cover opening member are just inserted into the gap between the multi-tube and the multi-tube cover.

[0078] Among them, the third elastic member 231 can elastically support the placement member 22, so that during the process of opening the cover, the placement member 22 and the multi-tube cover 212 can be positioned together in the vertical direction, which is convenient for opening the cover.

[0079] After opening the cover of the multi-tube assembly 21, the cover opening device can also perform a cover closing operation on it. Specifically, the moving mechanism can drive the driving member 11 to move, so as to place the clamped eight-tube cover on the eight-tube. Then, the driving member 11 drives the first clamping plate 13 and the second clamping plate to move away from each other, and the moving mechanism pressing plate 12 presses the eight-tube cover. During the cover closing process, the placing member 22 will be pressed on the supporting step 233 to play a supporting role.

[0080] It should be noted that the moving mechanism can also use a screw motor (equivalent to the Z-axis motion mechanism) to realize the cover closing process, wherein the screw motor has an encoder, which is convenient for confirming through closed-loop control that the moving mechanism drives the pressure plate 12 to move to the preset position, and tightens the eight-link tube cover, replacing the manual cover closing method that requires each hole to confirm that it is closed, thereby reducing the intensity of manual labor.

[0081] To sum up, the cover opening device can be understood as a multi-tube 211 cover opening and closing device. The driving member 11 of the cover opening device is used to drive the clamping member to move so that the edge of the first cover opening member 133 is inserted into the gap between the multi-tube 211 and the multi-tube cover 212, and the multi-tube 211 and the multi-tube cover 212 are propped open to separate the multi-tube 211 and the multi-tube cover 212 from each other, thereby replacing the manual cover opening method. At the same time, the edge of the first cover opening member 133 is driven by the clamping member to insert into the gap between the multi-tube 211 and the multi-tube cover 212, and the multi-tube 211 and the multi-tube cover 212 are propped open. The cover opening process is smooth, avoiding the risk of splashing during the cover opening process.

[0082] At the same time, the pressing plate 12 and the driving member 11 can be driven to move through the moving mechanism to realize the cover closing process, and then the cover opening device realizes the automation process of opening and closing the cover of the multi-connected pipe 211.

[0083] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
