DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] The utility model provides an automatic capping device to solve the problem that in the prior art, when opening the cap, the test tube must first be moved to a clamping mechanism that clamps the bottom of the test tube, and then the test tube must be rotated to open the cap, and then the test tube must be moved to a test tube rack, which is cumbersome to operate and has high cost; and because the threads of each bottle cap cannot be exactly the same, the cap is easily stuck or slipped when opening.

[0037] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 4 An automatic lid opening device in an embodiment of the present application comprises a base 1, a rotating clamp assembly 2, a sliding frame 3, a pull-out test tube rack 4, a clamping portion 5 and a test tube 6; the sliding frame 3 is slidably arranged in the Y-axis direction of the base 1. A plurality of pull-out test tube racks 4 are arranged in parallel on the sliding frame 3, and a plurality of parallel accommodating openings 40 for placing the test tubes 6 are opened in the pull-out test tube rack 4; a plurality of test tubes 6 are vertically arranged at the bottom of the pull-out test tube rack 4 through the corresponding accommodating openings 40, and the test tube 6 comprises a bottle body 60, a clamping adapter portion 61 extending downward from the bottom of the bottle body 60, and a bottle cap 62 threadedly connected to the top of the bottle body 60. The clamping portion 5 is telescopically arranged at the bottom of the pull-out test tube rack 4 through an elastic component 51, and the clamping adapter portion 61 is arranged correspondingly to the clamping portion 5 up and down; the rotating clamping jaw assembly 2 is arranged on the base 1, and can move in the X-axis direction and the Z-axis direction above the pull-out test tube rack 4 through a bidirectional movable module 8, so as to clamp the bottle cap 62 and then rotate it.

[0038] In the automatic capping device of the present invention, the bidirectional movable module 8 drives the rotating clamping claw assembly 2 to clamp the bottle cap 62 and then press it down, the clamping part 5 is clamped and connected with the clamping adapter part 61 up and down, the rotating clamping claw assembly 2 drives the bottle cap 62 to rotate and rise to open the cap, and the bottle body is connected to the clamping part 5 at this time and does not rotate, so that the test tube can be directly opened on the pull-out test tube rack 4, the operation is simple and convenient, and the improvement cost is low.

[0039] In addition, when the bottle cap and the bottle body are pressed downward, the elastic component 51 is in a compressed state, and the elastic component 51 provides an upward buffering force to adapt to the rotation of the bottle cap 62. The upward buffering force here refers to the characteristics of the elastic component 51 itself, which allows the bottle cap to rise slowly, stably and orderly to open the cap, prevents the mismatch between the thread of the bottle cap and the rotation speed of the bottle cap, and effectively avoids sticking and slipping when opening the cap.

[0040] based on Figure 1 In this embodiment, the bidirectional movable module 8 includes an X-direction movable seat 80, and the X-direction movable seat 80 can be moved in the X-axis direction above the base 1 through the X-direction movable module 81; a Z-direction movable module 82 is installed on the X-direction movable seat 80, and the Z-direction movable module 82 drives the rotating clamping jaw assembly 2 to rise and fall in the Z-axis direction of the base 1, and the two cooperate with each other to realize the movement of the rotating clamping jaw assembly 2 in the X and Z directions. Specifically, in this embodiment, the X-direction movable module 81 and the Z-direction movable module 82 are both motor screw drive mechanisms.

[0041] In addition, the sliding frame 3 can be moved in the Y-axis direction of the base 1 through the Y-axis moving module 83, so that the position of the rotating clamping jaw assembly 2 can be adjusted in the X-axis and Z-axis, and the sliding frame 3 can drive the test tube 6 to adjust the position in the Y-axis, thereby ensuring that the rotating clamping jaw assembly 2 can clamp all the bottle caps 62 on multiple pull-out test tube racks 4 and then press them down.

[0042] In this embodiment, the rotating jaw assembly 2 includes two jaws driven by a jaw motor, and the two jaws are driven to rotate synchronously by the rotating motor. When the two jaws clamp the bottle cap, the rotating motor synchronously drives the bottle cap to rotate, and the Z-axis moving module 82 drives the bottle cap to rise, so that after clamping the bottle cap 62, the bottle cap 62 is rotated and moved upward to realize the opening action between the bottle body 60.

[0043] based on Figure 1 In this embodiment, the pull-out test tube rack 4 is a U-shaped carrier frame composed of two horizontal plates 41 and two vertical plates 42, wherein the clamping portion 5 is arranged in a horizontal plate 41 located at the bottom.

[0044] based on Figure 2 In this embodiment, the test tube 6 is composed of a bottle body 60, a clamping adapter 61 and a bottle cap 62. The clamping adapter 61 is a cylinder coaxially arranged with the bottom of the bottle body 60, so that the clamping adapter 61 forms a cavity at the bottom of the bottle body 60. When the bottle body 60 is pressed down, the clamping portion 5 is clamped at the edge of the cavity, so that the bottle body 60 will not be damaged, and the clamping depth is not very deep. It is only necessary to fix the bottle body 60 to prevent it from rotating synchronously with the bottle cap 62.

[0045] based on Figures 3 to 5 In this embodiment, the clamping portion 5 includes a support block 50 arranged at the bottom of the pull-out test tube rack 4. The support block 50 is located in the base 1 and extends upward to the bottom of the pull-out test tube rack 4. A mounting block 52 is provided in the support block 50, which can be extended and retracted in the support block 50 by an elastic component 51. The mounting block 52 is non-circular, so that the mounting block 52 cannot rotate in the support block 50. The cross section of the mounting block 52 in this embodiment is T-shaped. A plurality of blades 53 are provided on the upper surface of the mounting block 52, and the blades 53 are correspondingly arranged below the clamping adapter 61; at the same time, in order to limit the upward movement distance of the mounting block 53, a limiting opening 43 for limiting the upward movement of the mounting block 52 is also opened on the pull-out test tube rack 4. When the mounting block 52 moves to the limiting opening 43, the mounting block 52 will not move.

[0046] During operation, the bottle body 60 is pressed down a certain distance by the rotating jaw assembly 2, and multiple blades 53 are inserted into the clamping adapter 61, so that the bottle body 60 and the mounting block 52 are clamped and connected, and at the same time, the mounting block 52 is in a compressed state driven by the elastic component 51; when the rotating jaw assembly 2 drives the bottle cap to rotate and rise to open the cap, the bottle cap and the bottle body are connected together, but the bottle body cannot rotate after being connected to the mounting block 52 through the blade 53, so the bottle cap is driven by the rotating jaw assembly 2 to perform the opening operation, which has a simple structure and low cost.

[0047] At the same time, when the rotating clamping jaw assembly 2 drives the bottle cap to rise, the elastic component 51 will recover its elasticity and rise, which is equivalent to providing the bottle cap with an upward adaptive buffering force, so that the bottle cap and the bottle body can be stably separated without getting stuck or slipping.

[0048] The depth to which the blade 53 is pressed down to the clamping adapter portion is the magnitude of the upward buffering force provided by the spring to the bottle cap, which can adapt to bottle caps with different needs and improve practicality.

[0049] In addition, the blade 53 in this embodiment is made of stainless steel, and the elastic component 51 can be used as a spring, and of course other elastic components can also be used.

[0050] based on Figure 4 In this embodiment, two spring pieces 8 located in the pull-out test tube rack 4 are further provided below the bottom of the accommodating opening 40. The spring pieces 8 are elastic, so that the test tube 6 can be guided in the center to ensure accurate opening of the cover. At the same time, the spring pieces 8 are elastic, so that they can adapt to the insertion of test tubes 6 of different specifications.

[0051] The specific workflow is as follows:

[0052] 1. First, rotate the clamping jaw assembly 2 to start working, so that the two clamping jaws are in a loose state;

[0053] 2. The bidirectional moving module 8 drives the rotating clamping jaw assembly 2 to move to the bottle cap to be opened, and the Y-axis position of the bottle cap is adjusted by the Y-axis moving module. Then the bidirectional moving module 8 continues to drive the rotating clamping jaw assembly 2 to move downward to clamp the bottle cap 62;

[0054] 3. The bidirectional moving module 8 drives the bottle cap and the bottle body to move down synchronously for a certain distance, and the multiple blades 53 are inserted into the clamping adapter to fix the bottle body and the mounting block, and the spring is compressed at the same time;

[0055] 4. The rotating jaw assembly 2 drives the bottle cap 62 to move upward while rotating. At this time, since the bottle body is connected to the mounting block and cannot rotate, the test tube will not move upward with the bottle cap. At the same time, under the guidance of the elastic restoring force of the spring, the force of the bottle cap driven upward by the rotating jaw assembly can be adapted through the elastic restoring force of the elasticity to prevent the bottle cap from getting stuck or slipping due to the incompatibility of the rotation speed and the thread.

[0056] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
