Description

Technical Field

[0001] This invention belongs to the technical field of experimental equipment, and in particular relates to a bottle cap screwing device. Background Technology

[0002] When sampling samples from test bottles in the laboratory, an automated sampling device is usually used to automatically sample the samples from the test bottles. In this process, a robotic arm is used to unscrew the cap from the bottle body, and then a sampling tool is used to take the sample from inside the bottle body.

[0003] Currently, existing automated sampling equipment requires two sets of robotic arms to unscrew the bottle cap from the bottle. Specifically, one set of robotic arms holds the bottle body, while the other holds the cap. Then, by selectively driving both sets of robotic arms, the cap is rotated relative to the bottle body. While this structure can achieve the action of unscrewing the cap, it is complex and requires two sets of robotic arms to work together, thus increasing equipment costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a bottle cap screwing device to address the technical problems existing in the prior art.

[0005] A bottle cap screwing device is used to clamp a test bottle and unscrew the bottle cap from the bottle body; the bottle cap screwing device includes:

[0006] Mounting base, which is detachably mounted on the robotic arm;

[0007] A bottle body clamping mechanism is telescopically mounted on the mounting base, and the bottle body clamping mechanism can clamp the bottle body under the drive of the mounting base;

[0008] A bottle cap clamping mechanism, rotatably mounted on the mounting base, wherein the bottle cap clamping mechanism includes a bottle cap clamping assembly, and the bottle cap clamping assembly is capable of clamping the bottle cap under the drive of the mounting base; and

[0009] A rotary drive component is mounted on the mounting base and connected to the bottle cap clamping mechanism to control the rotation of the bottle cap relative to the bottle body under the drive of the rotary drive component.

[0010] In this application, the mounting base can drive the bottle body clamping mechanism and the bottle cap clamping mechanism to clamp the bottle body and the bottle cap respectively. Then, the rotation drive is used to drive the bottle cap clamping mechanism to rotate, so as to unscrew the bottle cap from the bottle body. This allows the bottle cap screwing device to complete the action of unscrewing the bottle cap by mounting the mounting base on a set of robotic arms, which simplifies the structure and reduces costs.

[0011] In one embodiment, the bottle cap clamping assembly includes a plurality of bottle cap clamping units, which are arranged at circumferential intervals along the bottle cap.

[0012] Each of the bottle cap clamping units includes a first connecting rod and a first clamping member. The first connecting rod is rotatably connected to the first clamping member. The first connecting rod can press against the bottle cap and can drive the first clamping member to rotate relative to the bottle cap under the push of the bottle cap, so as to clamp the bottle cap.

[0013] It is understandable that the bottle cap clamping assembly is set up as multiple bottle cap clamping units, and the first connecting rod on the bottle cap clamping unit is driven by the reverse push of the bottle cap to clamp the bottle cap of the first clamping member. This enables the bottle cap clamping assembly to clamp the bottle cap under the drive of the mounting base, thereby specifically realizing the structure of the bottle cap clamping unit, which has the function of simplifying the structure.

[0014] In one embodiment, the bottle cap clamping mechanism further includes a connecting rod, which is rotatably mounted on the mounting base;

[0015] A connecting main board is formed on the connecting rotating rod, and multiple bottle cap clamping units are mounted on the connecting main board.

[0016] It is understandable that multiple bottle cap clamping units are installed on the connecting main board of the connecting rod, thereby specifically realizing the assembly and connection of the bottle cap clamping component in the bottle cap clamping mechanism.

[0017] In one embodiment, the first link is rotatably mounted on the connecting motherboard;

[0018] The connecting motherboard has an abutment portion, and the first clamping member can abut against the abutment portion and rotate relative to the abutment portion under the drive of the first connecting rod until the first clamping member clamps the bottle cap.

[0019] It is understandable that the first link is rotatably mounted on the connecting motherboard, and the abutment on the connecting motherboard is used to abut and support the rotation of the first clamping member on the connecting motherboard, thus specifically realizing the assembly connection of the first link and the first clamping member on the connecting motherboard.

[0020] In one embodiment, the bottle clamping mechanism includes a mounting main board, a plurality of bottle clamping components and an elastic element. The mounting main board is retractably mounted on the mounting base. The plurality of bottle clamping components are arranged at intervals along the circumference of the bottle. Each bottle clamping component is movably connected to the mounting main board, and the plurality of bottle clamping components can clamp the bottle simultaneously under the reverse push of the bottle.

[0021] The elastic element is disposed between the mounting motherboard and the mounting base to drive the mounting motherboard to elastically reset on the mounting base.

[0022] It is understandable that the structural configuration of the bottle clamping mechanism is specifically achieved through the above-mentioned installation of the main board, multiple bottle clamping components, and elastic elements.

[0023] In one embodiment, the bottle clamping assembly includes a second clamping member, a second connecting rod, and a top ring. The second clamping member is rotatably mounted on the mounting main plate, one end of the second connecting rod is rotatably mounted on the second clamping member, and the other end of the second connecting rod is rotatably connected to the top ring.

[0024] The top ring has a bottleneck abutment, which can press against the neck of the bottle body, so that the second connecting rod can drive the second clamping member to clamp the bottle body under the reverse push of the bottle body.

[0025] It is understandable that the structure of the bottle clamping assembly is specifically achieved through the aforementioned second clamping member, second connecting rod, and top ring.

[0026] In one embodiment, the bottle clamping assembly further includes a stop block mounted on the second clamping member and capable of abutting upward against the second link to restrict the second link from rotating downward relative to the second clamping member.

[0027] Understandably, the abutment block is used to press against the second link upwards to prevent the second link from sagging when installed on the second clamping member, so as to meet the usage requirements that the bottleneck abutment part of the top ring can press against the neck of the bottle under the action of the mounting base.

[0028] In one embodiment, the bottleneck abutment is configured as a ring structure.

[0029] It is understandable that the bottleneck abutment is set as a ring structure, thus specifically realizing the structural design of the bottleneck abutment to meet the usage requirements of pressing against the neck of the bottle.

[0030] In one embodiment, the mounting base includes a sleeve, the mounting motherboard is fitted onto the sleeve, and can reciprocate relative to the sleeve along the axial direction of the sleeve;

[0031] The sleeve has a guide key, and the mounting motherboard has a keyway. The guide key cooperates with the keyway to circumferentially limit the mounting motherboard to the sleeve.

[0032] It is understandable that the guide key on the sleeve and the keyway on the mounting motherboard are used to guide the lifting and lowering movement of the mounting motherboard on the sleeve, thus ensuring the stability of the bottle clamping mechanism when the bottle cap screwing device is working.

[0033] In one embodiment, the second clamping member is provided with a buffer, and the second clamping member is able to clamp the bottle body through the buffer.

[0034] Understandably, the second clamping component uses a buffer to hold the bottle body, which cushions the grip of the bottle body and prevents damage to the bottle body when the second clamping component holds the test bottle.

[0035] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0036] The bottle cap screwing device of the present invention has a mounting base that can drive the bottle body clamping mechanism and the bottle cap clamping mechanism to clamp the bottle body and the bottle cap respectively. Then, the bottle cap clamping mechanism is rotated by a rotary drive component to achieve the purpose of unscrewing the bottle cap from the bottle body. This allows the bottle cap screwing device to complete the action of unscrewing the bottle cap by mounting the mounting base on a set of robotic arms, which simplifies the structure and reduces costs.

Specific Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] The bottle cap screwing device claimed in this application is used to hold the test bottle 200 and can unscrew the bottle cap 201 from the bottle body 202.

[0045] like Figures 1 to 3 As shown, an embodiment of this application provides a bottle cap screwing device, including a mounting base 10, a bottle body clamping mechanism 20, a bottle cap clamping mechanism 30, and a rotary drive 40. The mounting base 10 is detachably mounted on a robotic arm (not shown). The bottle body clamping mechanism 20 is telescopically mounted on the mounting base 10, and under the drive of the mounting base 10, the bottle body clamping mechanism 20 can clamp the bottle body 202. The bottle cap clamping mechanism 30 is rotatably mounted on the mounting base 10, wherein the bottle cap clamping mechanism 30 includes a bottle cap clamping assembly 31, and under the drive of the mounting base 10, the bottle cap clamping assembly 31 can clamp the bottle cap 201. The rotary drive 40 is mounted on the mounting base 10 and connected to the bottle cap clamping mechanism 30, so as to control the bottle cap 201 to rotate relative to the bottle body 202 under the drive of the rotary drive 40.

[0046] It is understood that when the bottle cap screwing device of this application is working, the robot arm can drive the bottle body clamping mechanism 20 and the bottle cap clamping mechanism 30 to clamp the bottle body 202 and the bottle cap 201 respectively through the mounting base 10. Then, the rotation drive 40 is used to drive the bottle cap clamping mechanism 30 to rotate, so as to achieve the purpose of unscrewing the bottle cap 201 from the bottle body 202. This makes the bottle cap screwing device able to complete the action of unscrewing the bottle cap 201 by mounting the mounting base 10 on a set of robot arms, which simplifies the structure and reduces costs.

[0047] It should be noted that during the rotation of the bottle cap clamping mechanism 30 by the rotary drive 40, the robotic arm can appropriately lift the bottle body clamping mechanism 20 and the bottle cap clamping mechanism 30 through the mounting base 10, so that the bottle cap 201 can move up and down relative to the bottle body 202 while rotating, thus meeting the requirement of unscrewing the bottle cap 201 from the bottle body 202. Of course, the robotic arm mentioned above can be a conventional robotic arm used in current automated sampling equipment. When the bottle cap screwing device is working, the robotic arm can drive the mounting base 10 to move up and down relative to the test bottle 200, and use the up and down movement of the bottle body clamping mechanism 20 and the bottle cap clamping mechanism 30 to clamp the bottle body 202 and the bottle cap 201 respectively.

[0048] The mounting base 10 is used in the bottle cap screwing device, specifically as the mounting base for the bottle body clamping mechanism 20, the bottle cap clamping mechanism 30 and the rotary drive component 40. The entire bottle cap screwing device can be installed on the robot arm by mounting the mounting base 10 on the robot arm.

[0049] The mounting base 10 includes a sleeve 11, and the bottle body clamping mechanism 20 is telescopically mounted on the sleeve 11, while the bottle cap clamping mechanism 30 is rotatably mounted on the sleeve 11.

[0050] In one embodiment, the bottle clamping mechanism 20 includes a mounting main board 21, multiple bottle clamping components 22, and an elastic element 23. The mounting main board 21 is telescopically mounted on the mounting base 10. Specifically, the mounting main board 21 can be fitted onto the sleeve 11 and can move up and down relative to the sleeve 11 along the axial direction. The multiple bottle clamping components 22 are arranged at intervals along the circumference of the bottle body 202. Each bottle clamping component 22 is movably connected to the mounting main board 21, and the multiple bottle clamping components 22 can simultaneously clamp the bottle body 202 when pushed in the direction of the bottle body 202. The elastic element 23 is disposed between the mounting main board 21 and the mounting base 10 to drive the mounting main board 21 to elastically reset on the mounting base 10. It should be noted that the above-mentioned elastic element 23 can be specifically set as a spring. Of course, those skilled in the art can also provide the elastic element 23 with a certain elasticity, such as a rubber sleeve or a corrugated tube, which will not be elaborated here.

[0051] It should be noted that the bottle clamping mechanism 20 has two bottle clamping components 22, which are symmetrically arranged on the mounting motherboard 21. Of course, those skilled in the art can also set the number of bottle clamping components 22 to three, four, or even more.

[0052] The sleeve 11 has a guide key 111, and the mounting main board 21 has a keyway (not shown). The guide key 111 cooperates with the keyway to circumferentially limit the mounting main board 21 to the sleeve 11. When the bottle cap screwing device is working, the cooperation between the guide key 111 on the sleeve 11 and the keyway on the mounting main board 21 can guide the lifting and lowering movement of the mounting main board 21 on the sleeve 11. This ensures the stability of the bottle body clamping mechanism 20 when clamping the bottle body 202 when the bottle cap screwing device is working.

[0053] Secondly, a limiting baffle 112 is also formed on the sleeve 11. The limiting baffle 112 can abut against the mounting motherboard 21 upwards, and the abutment between the limiting baffle 112 and the mounting motherboard 21 is used to prevent the mounting motherboard 21 from detaching from the sleeve 11.

[0054] The bottle clamping assembly 22 includes a second clamping member 221, a second connecting rod 222, and a top ring 223. The second clamping member 221 is rotatably mounted on the mounting main board 21. One end of the second connecting rod 222 is rotatably mounted on the second clamping member 221, and the other end of the second connecting rod is rotatably connected to the top ring 223.

[0055] The top ring 223 has a neck abutment portion 2231, which can press against the neck 2021 of the bottle body 202. Under the push of the bottle body 202, the second connecting rod 222 can drive the second clamping member 221 to clamp the bottle body. That is to say, in the process of clamping the bottle body 202, the bottle body clamping mechanism 20 utilizes action and reaction forces, combined with the structural characteristics of the neck 2021 on the bottle body 202, so that as the neck abutment portion 2231 of the top ring 223 abuts against the neck 2021 of the bottle body 202 and descends, the top ring 223 can push the second connecting rod 222 upward. Under the transmission of the second connecting rod 222, the second clamping member 221 is driven to rotate towards the bottle body 202 on the mounting plate 21 until the second clamping member 221 clamps the bottle body 202.

[0056] The second clamping member 221 is equipped with a buffer member 2211, which clamps the bottle body 202. This buffer member 2211 utilizes its structural characteristics to cushion the clamping action of the second clamping member 221 on the bottle body 202, preventing damage to the bottle body 202 when clamping the test bottle 200. It should be noted that the buffer member 2211 can be made of rubber, silicone, etc., which will not be elaborated upon here.

[0057] The bottleneck abutment 2231 is configured as a ring structure to match the neck 2021 of the bottle body 202, so as to meet the usage requirements of the top ring 223 pressing against the neck 2021 of the bottle body 202 with the bottleneck abutment 2231.

[0058] The bottle clamping assembly 22 also includes a stop block 224, which is mounted on the second clamping member 221 and can abut against the second connecting rod 222 upwards to restrict the second connecting rod 222 from rotating downwards relative to the second clamping member 221. This prevents the second connecting rod 222 from drooping after being mounted on the second clamping member 221, so as to meet the usage requirements that the bottleneck abutment portion 2231 of the top ring 223 can press against the neck 2021 of the bottle body 202 under the drive of the mounting base 10.

[0059] In one embodiment, the bottle cap clamping assembly 31 includes bottle cap clamping units, a plurality of bottle cap clamping units being arranged at circumferential intervals along the bottle cap 201.

[0060] Each bottle cap clamping unit includes a first connecting rod 311 and a first clamping member 312. The first connecting rod 311 and the first clamping member 312 are rotatably connected. The first connecting rod 311 can press against the bottle cap 201 and, under the push of the bottle cap 201, can drive the first clamping member 312 to rotate relative to the bottle cap 201 to clamp the bottle cap 201. In other words, during the process of clamping the bottle cap 201, the bottle cap clamping unit utilizes the action and reaction forces between the first connecting rod 311 and the bottle cap 201 to drive the first clamping member 312 toward the bottle cap 201 as the mounting base 10 drives the bottle cap clamping mechanism 30 to descend, thereby achieving the clamping of the bottle cap 201.

[0061] It should be noted that the bottle cap clamping assembly 31 has two bottle cap clamping units, which are symmetrically located on both sides of the bottle cap 201. Of course, for those skilled in the art, the number of bottle cap clamping units can also be three, four, or even more, which will not be elaborated here.

[0062] The bottle cap clamping mechanism 30 also includes a connecting rod 32, which is rotatably mounted on the mounting base 10. Specifically, the connecting rod 32 passes through the sleeve 11.

[0063] A connecting main board 321 is formed on the connecting rod 32, and multiple bottle cap clamping units are installed on the connecting main board 321.

[0064] Specifically, the first connecting rod 311 is rotatably mounted on the connecting main board 321; the connecting main board 321 has an abutment portion 3211, the first clamping member 312 can abut against the abutment portion 3211, and rotate relative to the abutment portion 3211 under the drive of the first connecting rod 311 until the first clamping member 312 clamps the bottle cap 201, thus specifically realizing the assembly connection of the first connecting rod 311 and the first clamping member 312 on the connecting main board 321.

[0065] In one embodiment, the rotary drive 40 is configured as a rotary drive or a rotary drive motor.

[0066] As can be seen from the above, when the bottle cap screwing device of this application is working, the bottle body clamping mechanism 20 and the bottle cap clamping mechanism 30 descend toward the test bottle 200 under the drive of the mounting base 10. The top ring 223 on the bottle body clamping assembly 22 first contacts the neck 2021 of the bottle body 202. By utilizing the action and reaction forces, under the transmission of the second connecting rod 222, the second clamping member 221 can clamp the bottle body 202. At the same time, the first connecting rod 311 on the bottle cap clamping assembly 31 will abut against the bottle cap 201, and under the transmission of the first connecting rod 311, the first clamping member 312 can clamp the bottle cap 201. Then, the rotary drive 40 is activated to select and drive the bottle cap clamping mechanism 30. During this process, the bottle body clamping mechanism 20 and the bottle cap clamping mechanism 30 rise away from the test bottle 200 under the drive of the mounting base 10. The elastic member 23 provides elastic support to the mounting motherboard 21 in the bottle body clamping mechanism 20, which is mounted on the sleeve 11 on the mounting base 10. This allows the bottle cap clamping mechanism 30 to rise with the mounting base 10, while the bottle body clamping mechanism 20 retains its original position, thereby achieving the drive to unscrew the bottle cap 201 from the bottle body 202.

[0067] In summary, the bottle cap screwing device of this application can be mounted on a robotic arm with the mounting base 10 as the mounting base. It simplifies the structure and reduces costs in meeting the usage requirements of unscrewing the bottle cap 201 from the bottle body 202.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
