Description

Technical Field

[0001] The present invention relates to the technical field of biological analysis, and in particular to an analyzer. Background Art

[0002] The three-dimensional precision motion robotic arm in the fully automatic biochemical analyzer can simultaneously realize the rotation and lifting movements of the robotic arm. It is one of the key components of the biochemical analyzer. Since it can replace manual operations to automatically add samples, take samples, pipet liquids and other actions, its positioning during rotation is extremely demanding.

[0003] In existing analyzers, the rotational positioning of the robotic arm is primarily achieved through the cooperation of a code disk and a coupler. The coupler emits two beams of sensing light, which detect the notch on the code disk to position and move the robotic arm. This manufacturer-made coupler encapsulates two optocouplers within a single plastic shell. The position of the optocouplers is relatively fixed and cannot be changed. Therefore, when machining the notch on the code disk, the relative position of the inner and outer ring notches along the diameter must match the position of the optocouplers, resulting in high machining precision and increased processing costs. Furthermore, dual-beam couplers are more expensive than single-beam couplers and are currently difficult to procure on the market, increasing costs and the risk of supply interruption.

[0041] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0045] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] In existing analyzers, the rotational positioning of the robotic arm is primarily achieved through the cooperation of a code disk and a coupler. The coupler emits two beams of sensing light, which detect the notches on the code disk to position and move the robotic arm. This manufacturer-made coupler has a relatively fixed beam position that cannot be changed. Therefore, when machining the notches on the code disk, the relative diametrical positions of the inner and outer rings must match the coupler, requiring high machining precision and increasing costs. Furthermore, dual-beam couplers are more expensive than single-beam couplers and are currently difficult to procure, increasing costs and the risk of supply disruption.

[0047] In order to solve the above problems, the present invention provides an analyzer.

[0048] See also Figure 1 and Figure 2 In one embodiment of the present invention, the analyzer 100 includes a frame 2, a rotating mechanism 3, a robotic arm 4, a coupling mechanism 1, and a rotary code disk 5. The rotating mechanism 3 is mounted on the frame 2; the robotic arm 4 is inserted into the frame 2 and connected to the rotating mechanism 3, which drives the robotic arm 4 to rotate; the coupling mechanism 1 includes a first coupling component 11 and a second coupling component 13, both of which are mounted on the frame 2 and spaced apart; and the rotary code disk 5 is sleeved on the robotic arm 4 and spaced apart from the rotating mechanism 3. The outer periphery of the rotary code disk 5 is provided with a positioning structure 51 protruding from the outer edge of the rotary code disk 5 and a plurality of detection structures 53. The first coupling component 11 is used to detect the positioning structure 51 to reset the robotic arm 4, and the second coupling component 13 is used to detect the detection structure 53 to rotate the robotic arm 4 to different working positions.

[0049] The technical solution of the present invention comprises a rotating mechanism 3 mounted on a frame 2, and a robotic arm 4 inserted through the frame 2 and connected to the rotating mechanism 3, so that the rotating mechanism 3 can drive the robotic arm 4 to rotate. Furthermore, a coupling mechanism 1 is provided on the frame 2, comprising a first coupling assembly 11 and a second coupling assembly 13 spaced apart. A rotary code disk 5 is mounted on the robotic arm 4, and the rotary code disk 5 is provided with a positioning structure 51 and multiple detection structures 53. The first coupling assembly 11 detects the positioning structure 51 to reset the robotic arm 4, and the second coupling assembly 13 is used to detect the detection structure 53 to rotate the robotic arm 4 to different working positions. By improving the structure of the rotary code disk 5 and providing two coupling assemblies to detect and determine the improved structure of the rotary code disk 5, the present invention resets the robotic arm 4 and moves it to its working position based on the information fed back by the two coupling assemblies. This reduces the processing accuracy and cost of the rotary code disk 5, while also reducing the purchase cost and risk of out-of-stock dual-fiber couplers, thereby ensuring efficient operation of the product production line.

[0050] See also Figure 2 and Figure 3 In one embodiment of the present invention, the positioning structure 51 is a positioning protrusion, and the detection structure 53 includes a plurality of detection notches; and / or, the positioning structure 51 is a positioning notch, and the detection structure 53 includes a plurality of detection protrusions.

[0051] The positioning structure 51 can be a circular arc-shaped protrusion, in which case the detection structure 53 can be set as a plurality of detection notches. The positioning structure protrudes from the outer edge of the rotating code disk 5 and is set in the same plane as the rotating code disk 5, so that when the rotating code disk 5 rotates with the robotic arm 4, the positioning structure 51 can also rotate in the same plane with the rotating code disk 5, so that the positioning structure 51 can pass through the first gap. When the positioning structure 51 passes through the first gap, the light emitted by the first emitting part is blocked by the positioning structure 51, so that the first receiving part 111c does not receive the light signal emitted from the first emitting part. At this time, the control system can determine that the robotic arm 4 has been reset to the original position and can proceed to the next step of the sample analysis process. In other embodiments, the positioning structure 51 can also be other shapes, such as square, trapezoidal, etc., to correspond to the light signals of different light beams, and there is no limitation here. Because the positioning structure 51 protrudes from the rotating code disk 5, and the two couplers are positioned one inside and one outside relative to the code disk, the outer ring of the code disk may touch the first coupler on the inner side. In one embodiment, the arc protrusion of the outer ring can be limited. Two stainless steel cylinders with threads on the lower ends are installed on the frame 2 to ensure that when the rotating mechanism 3 rotates, the arc protrusion on the code disk is within the range of the two cylinders, thereby achieving the purpose of mechanically limiting the arc protrusion. The second coupler 131 is used to sense the detection structure 53 on the rotary code disk 5. The rotary code disk 5 begins to rotate from its original position after the robot arm 4 is reset, with its periphery located within the second gap. During this process, the light emitted by the second emitting portion of the second coupler 131 is continuously blocked by the rotary code disk 5 until it reaches the first detection notch. At this point, the second receiving portion senses the light signal, and the control system determines that the robot arm 4 has rotated to the first working position, thereby initiating the next step of the sample analysis process. The second coupler 131 cooperates with the notch in the rotary code disk 5 to enable the robot arm 4 to rotate to different working positions. The area of the notch can be adjusted based on the position of the light emitted by the second coupler 131. Because the position of the second coupler 131 relative to the first coupler 111 can be adjusted to suit different robot arm working positions, the processing cost of the notch is reduced. Multiple detection notches can be machined on the rotary code disk 5 to correspond to different working positions of the robot arm 4. This reduces the processing accuracy requirements and reduces the processing cost. In one embodiment of the present invention, the positioning structure 51 can also be configured as a positioning notch, and the detection structure 53 can be configured as a detection protrusion.

[0052] See Figure 2In one embodiment of the present invention, the first coupling component 11 includes a first coupler 111 and a first mounting seat 113, the first mounting seat 113 is installed on the frame 2, and the first coupler 111 is passed through the first mounting seat 113; the second coupling component 13 includes a second coupler 131 and a second mounting seat 133, the second mounting seat 133 is installed on the frame 2, the second mounting seat 133 is spaced apart from the first mounting seat 113, and the second coupler 131 is passed through the second mounting seat 133.

[0053] The first coupling assembly 11 includes a first coupler 111 and a first mounting seat 113. The first coupler 111 is a coupler with an optical coupler encapsulated in a plastic shell. It can emit a beam of sensing light, and the emitted light signal can detect the positioning structure 51. Similarly, the second coupler 131 is also a coupler with an optical coupler encapsulated in a plastic shell. The light signal emitted by the second coupler 131 can detect the detection structure 53. Compared with a dual optical coupler in which both optical couplers are encapsulated in a plastic shell, the provision of two coupling assemblies reduces procurement costs and avoids the risk of dual optical couplers being out of supply, thereby ensuring the efficient operation of the product production line. The optical couplers are respectively provided on the two mounting seats, and the relative positions of the first mounting seat 113 and the second mounting seat 133 are adjustable, so that the relative positions of the positioning structure 51 and the detection structure 53 of the rotary code disk 5 can also be adjusted according to the actual needs of the working position of the robot arm 4. The user no longer needs to match the notch of the rotary code disk 5 according to the relative positions of the optical couplers of the dual optical couplers, thereby reducing the processing accuracy of the rotary code disk 5 and reducing the processing cost. The first mounting base 113 can be detachably mounted on the frame 2 by means of a screw structure, which facilitates adjustment of the position of the first mounting base 113 and the processing and assembly of the entire device. In another embodiment, the first mounting base 113 can also be integrally formed with the frame 2 to further enhance the compactness of the structure and make the connection of the first mounting base 113 more stable. In other embodiments, the first mounting base 113 can also be connected to the frame 2 by other connecting structures, which is not limited here. It can be understood that the second mounting base 133 is spaced apart from the first mounting base 113, and the second mounting base 133 can be connected to the frame 2 by means of a screw structure, which facilitates the disassembly and assembly of the second mounting base 133, so that the relative position of the second coupler 131 and the detection structure 53 can be adjusted according to the different working positions of the robot arm 4, so that the analyzer 100 can be applied to more working scenarios. In other embodiments, the second mounting base can also be connected to the frame 2 by means of other connecting structures.

[0054] See Figure 2In one embodiment of the present invention, the first coupler 111 includes a first transmitting portion 111a and a first receiving portion 111c provided on a first mounting seat 113, and a first gap is provided between the first transmitting portion 111a and the first receiving portion 111c so that the positioning structure 51 passes through the first gap; and / or, the second coupler 131 includes a second transmitting portion and a second receiving portion provided through a second mounting seat 133, and a second gap is provided between the second transmitting portion and the second receiving portion, and the periphery of the rotating code disk 5 is located in the second gap to detect the detection structure 53.

[0055] The first coupler 111 includes an optocoupler encapsulated therein, and the optocoupler emits light from the first emitting part, which passes through the first gap and reaches the first receiving part 111c. The positioning structure 51 can pass through the first gap. When the positioning structure 51 is located in the first gap, the light signal emitted by the first emitting part is blocked by the positioning structure 51 and cannot reach the first receiving part 111c. At this time, the control system can determine that the robotic arm 4 has been reset; it can be understood that the second coupler 131 includes an optocoupler encapsulated therein, and the optocoupler emits light from the second emitting part. The outer edge of the rotating code disk 5 rotates in the second gap. When the detection structure 53 rotates to the second gap, the second receiving part can receive the light signal emitted by the second emitting part. At this time, the control system determines that the robotic arm 4 has reached the working position and can proceed to the next step of sample analysis.

[0056] See also Figure 2 and Figure 3 In one embodiment of the present invention, the first mounting seat 113 can be detachably mounted on the frame 2; and / or the second mounting seat 133 can be detachably mounted on the frame 2; and / or the rotary code disk 5 is a circular structure; the positioning structure 51 and the rotary code disk 5 are arranged on the same plane.

[0057] See Figure 2 In one embodiment of the present invention, the frame 2 is provided with a first limiting member 211, and the periphery of the rotating mechanism 3 is provided with a second limiting component 31, wherein when the rotating mechanism 3 rotates, the second limiting component 31 is in limiting contact with the first limiting member 211.

[0058] The frame 2 includes a mounting platform 21 and a machine body 23. The mounting platform 21 can be connected to the machine body 23 by a screw structure. The upper end of the rotating mechanism 3 is connected to the mounting platform, and the lower end of the rotating mechanism 3 is connected to the machine body 23. A first limiting member 211 can also be provided on the mounting platform 21, and a second limiting assembly 31 is provided on the periphery of the rotating mechanism 3. The first limiting member 211 and the second limiting assembly 31 cooperate to limit the extreme rotation position of the robotic arm 4. The first limiting member 211 can be selected from a longer screw. The second limiting assembly 31 includes a limiting ring 311 arranged around the rotating mechanism 3. The limiting ring 311 can be provided on a side of the rotating mechanism 3 close to the mounting platform 21. A second limiting member 3111 is provided on the limiting ring 311. The second limiting member 3111 can abut against the first limiting member 211 when the rotating mechanism 3 rotates to the extreme position of the robotic arm 4, thereby preventing the robotic arm 4 from colliding with other components of the analyzer 100 during rotation when the optical coupler fails, causing damage. In one embodiment, the limiting ring 311 can also be set on the side of the rotating mechanism 3 close to the machine body 23. In this case, the first limiting member 211 can be installed on the machine body 23, and the second limiting member 3111 can be installed on the limiting ring 311. When the rotating mechanism 3 rotates, the first limiting member 211 can abut against the second limiting member 3111. The first limiting member 211 can be a screw structure, which is installed on the mounting platform 21 and the lower end of the screw extends out of the mounting platform 21 long enough so that the first limiting member 211 and the second limiting member 31 can be in a limited abutment. In other embodiments, the first limiting member 211 can also be other structures, which are not limited here. Similarly, the second limiting member 3111 can be a screw, which is installed on the outer periphery of the limiting ring 311 and abuts against the lower end of the first limiting member 211 through the screw head, thereby limiting the rotation of the robotic arm 4 and preventing damage to the robotic arm 4.

[0059] See Figure 2 In one embodiment of the present invention, the analyzer 100 has two or more robotic arms 4, and the second limiting assembly 31 includes a limiting ring 311 and a second limiting member 3111 installed on the rotating mechanism. The limiting ring 311 is provided with at least two limiting holes, and at least one limiting hole is installed with the second limiting member 3111; when the rotating mechanism 3 rotates, the second limiting member 3111 is in limiting contact with the first limiting member 211.

[0060] It can be understood that the analyzer 100 has two or more robotic arms 4, so multiple limiting holes are opened on the limiting ring 311. Corresponding limiting holes are opened on the limiting ring 311 and a second limiting member 3111 is installed to meet the limiting requirements of the different functional robotic arms 4 on the analyzer 100.

[0061] See also Figure 2 and Figure 4In one embodiment of the present invention, the limiting ring 311 is provided with at least three limiting holes, at least two of which are equipped with second limiting members 3111, there are two first limiting members 211, and the two first limiting members 211 are arranged at intervals; when a second limiting member 3111 is in limiting contact with a first limiting member 211, the first limit position of the rotating mechanism 3 is limited; when another second limiting member 3111 is in limiting contact with another first limiting member 211, the second limit position of the rotating mechanism 3 is limited.

[0062] The two first limiting members 211 and the two second limiting members 3111 limit the extreme positions of the two ends of the robotic arm 4 to better protect the sample analysis equipment.

[0063] See also Figure 2 and Figure 4 In one embodiment of the present invention, there are two second limiting members 3111, the limiting ring 311 is provided with a second limiting hole 3113, one second limiting member 3111 is installed on the second limiting hole 3113, and the other second limiting member 3111 is installed on any other limiting hole.

[0064] The analyzer 100 has multiple robotic arms 4. The limiting threaded holes of multiple robotic arms 4 can be machined on the same limiting ring 311. At the same time, to reduce the number of threaded holes, the second limiting hole 3113 is specified as a common hole, that is, each common hole on the robotic arm 4 needs to be installed with a second limiting member 3111. Then, the second limiting member 3111 is installed on the corresponding limiting hole according to the actual rotation range of different robotic arms 4. Multiple limiting holes set at intervals can be opened on the outer circumference of the limiting ring 311. These can be machined according to the extreme rotation positions of the robotic arm 4, so that the position of another second limiting member 3111 can be freely adjusted, further reducing processing costs.

[0065] See also Figure 2 and Figure 4 In one embodiment of the present invention, the robotic arm 4 includes two groups of robotic arms 4, and the end face of the limiting ring 311 includes a front side and a back side; when the front side of the limiting ring 311 faces upward, the second limiting component 31 limits one group of robotic arms 4; when the back side of the limiting ring 311 faces upward, the second limiting component 31 limits the other group of robotic arms 4.

[0066] Furthermore, the limiting position of the robotic arm 4 is relatively concentrated, so the limiting holes will also be concentrated on one side, which will cause the distance between multiple limiting holes to be too close, which is inconvenient to process. In one embodiment of the present invention, the limiting ring corresponding to the reagent needle usually connected to the analyzer 100 and the limiting ring corresponding to the sampling needle can be distinguished. On the premise of sharing the hole, the limiting hole for the sample needle can be processed on the front side of the limiting ring, and the limiting hole for the reagent needle can be processed on the back side of the limiting ring; of course, the limiting hole for the reagent needle can also be processed on the front side of the limiting ring, and the limiting hole for the sample needle can be processed on the back side. In this way, the distance between the limiting holes can be increased, and the processing of the limiting ring is convenient. From the actual solution point of view, the limiting holes can be evenly distributed, the processing accuracy can be reduced, and the processing cost can be reduced.

[0067] See Figure 2 In one embodiment of the present invention, the first limiting member 211 is a screw; and / or the second limiting member 3111 is a screw.

[0068] See Figure 2 In one embodiment of the present invention, the limiting ring 311 further includes a mounting screw, and the limiting ring 311 is installed on the rotating mechanism through the mounting screw and the second limiting member 311.

[0069] In one embodiment of the present invention, when one limit ring 311 may not be suitable for the extreme positions of multiple robotic arms 4, multiple limit rings 311 can be installed on the periphery of the rotating mechanism 3, and the limit rings 311 have limit holes at different positions corresponding to different robotic arms 4, so that the position of the second limit member 3111 can be adjusted to achieve the purpose of mechanically limiting different robotic arms 4.

[0070] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
