Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, specifically to a rotating mechanism, a scanning device, and a sample analyzer for barcode scanning. Background Technology
[0002] In disease diagnosis and treatment, the analytical results obtained by analyzing patient samples provide important reference for clinical diagnosis. In batch sample testing and analysis, barcodes are usually affixed to test tubes for easy identification and statistics. Then, a barcode scanning agency scans the barcodes on the test tubes. Only after successfully reading the barcode information can the subsequent testing and analysis work begin.
[0003] In existing technologies, clamping wheels and drive wheels are typically installed on both sides of the test tube. The clamping wheels and drive wheels clamp the test tube, and then the drive wheel rotates. Under the action of friction between the drive wheel and the test tube, the test tube rotates, so that the barcode scanning mechanism scans the barcode during the rotation of the test tube. However, in practical applications, the barcode may have raised edges, wrinkles, or the test tube may slip. These phenomena will prevent the test tube from rotating, resulting in scanning failure. Utility Model Content
[0004] This application mainly provides a rotating mechanism, scanning device, and sample analyzer for scanning, which can avoid edge lifting, wrinkles, protrusions, or test tube slippage, thus avoiding the risk of scanning failure caused by these phenomena.
[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a rotating mechanism for scanning codes, the rotating mechanism comprising: a clamping unit, including a clamping drive mechanism and a clamping wheel, the clamping drive mechanism being connected to the clamping wheel to drive the clamping wheel to move closer to or away from the object to be scanned; a driving unit, including a rotating drive mechanism and a driving wheel, the driving wheel being used to clamp the object to be scanned together with the clamping wheel, the rotating drive mechanism being connected to the driving wheel to drive the driving wheel to rotate in a first direction or a second direction, thereby causing the object to be scanned to rotate in the second direction or the first direction, the first direction being opposite to the second direction.
[0006] In one specific embodiment, the clamping unit further includes an adapter assembly, which includes an adapter and an adapter bracket. The adapter is connected to the clamping drive mechanism, the clamping wheel is connected to the adapter bracket, and the adapter bracket is movably mounted on the adapter and elastically abuts against the adapter.
[0007] In one specific embodiment, the adapter bracket includes a bracket body, a guide member, and an elastic member. The clamping wheel is connected to the bracket body, the guide member is slidably mounted on the adapter member and connected to the bracket body, and the elastic member abuts against the bracket body and the adapter member respectively.
[0008] In one specific embodiment, the adapter bracket further includes an anti-detachment component, the guide component passes through the adapter component, and the anti-detachment component is connected to the guide component on the side of the adapter component away from the bracket body.
[0009] In one specific embodiment, the clamping unit further includes a detection component, which includes a first detection mechanism and a detection element. The detection element is connected to the adapter bracket so that when the clamping wheel approaches the object to be scanned, the first detection mechanism detects whether the object to be scanned is present through the detection element.
[0010] In one specific embodiment, the detection component further includes a second detection mechanism, which is used to detect whether the pressure wheel is located at a preset starting position through the detection element.
[0011] In one specific embodiment, the clamping drive mechanism includes a clamping motor and a transmission assembly. The transmission assembly is connected to the output shaft of the clamping motor and the clamping wheel respectively, so that when the output shaft of the clamping motor rotates, the transmission assembly drives the clamping wheel to move closer to or away from the object to be scanned.
[0012] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a barcode scanning device, which includes a barcode scanning mechanism and the aforementioned rotating mechanism. The barcode scanning mechanism is used to scan the identification code on the object to be scanned during the rotation of the object.
[0013] In one specific embodiment, the scanning device further includes a control unit, which is communicatively connected to the pressing drive mechanism, the rotary drive mechanism, and the scanning mechanism. The control unit is used to control the rotary drive mechanism to drive the drive wheel to rotate in the first direction and to obtain the scanning result of the scanning mechanism. The control unit is also used to control the rotary drive mechanism to drive the drive wheel to rotate in the second direction when the scanning result does not contain the identification code.
[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a sample analyzer, characterized in that the sample analyzer includes a detection device and the scanning device, wherein the detection device is used to detect the sample to be detected placed in the object to be scanned.
[0015] The beneficial effects of this application are as follows: Unlike the prior art, the rotating mechanism for scanning provided in this application includes: a clamping unit, including a clamping drive mechanism and a clamping wheel, wherein the clamping drive mechanism is connected to the clamping wheel to drive the clamping wheel to move closer to or away from the object to be scanned; and a driving unit, including a rotating drive mechanism and a driving wheel, wherein the driving wheel is used to clamp the object to be scanned together with the clamping wheel, and the rotating drive mechanism is connected to the driving wheel to drive the driving wheel to rotate in a first direction or a second direction, thereby causing the object to be scanned to rotate in the second direction or the first direction, wherein the first direction is opposite to the second direction.

[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a three-dimensional structural schematic diagram of an embodiment of the barcode scanning device 10 provided in this application. Figure 2 yes Figure 1 Exploded view of the rotating mechanism 10a. Figure 3 yes Figure 1A front view of the rotating mechanism 10a. In this embodiment, the scanning device 10 includes a rotating mechanism 10a and a scanning mechanism 10b.
[0022] The rotating mechanism 10a includes a clamping unit 11 and a driving unit 12. The clamping unit 11 includes a clamping driving mechanism 111 and a clamping wheel 112. The clamping driving mechanism 111 is connected to the clamping wheel 112 to drive the clamping wheel 112 to rotate as follows: Figure 1 and Figure 2 As shown, A1 moves upwards towards the object to be scanned 110, or as... Figure 1 and Figure 2 As shown, A2 moves upwards away from the object to be scanned, 110.
[0023] It is understandable that the number of clamping rollers 112 can be one or more. In this embodiment, two clamping rollers 112 are used as an example, namely clamping roller 112a and clamping roller 112b.
[0024] Optionally, the clamping drive mechanism 111 includes a clamping motor 111a and a transmission assembly 111b. The transmission assembly 111b is connected to the output shaft of the clamping motor 111a and the clamping wheel 112 respectively, so that when the output shaft of the clamping motor 111a rotates, the transmission assembly 111b drives the clamping wheel 112 to move closer to or away from the object to be scanned 110.
[0025] The transmission assembly 111b includes a drive wheel 1111, a driven wheel 1112, and a conveyor belt 1113. The drive wheel 1111 is mounted on the output shaft of the pressure motor 111a. The conveyor belt 1113 is wound around the drive wheel 1111 and the driven wheel 1112 and connected to the pressure wheel 112. In this embodiment, there are two driven wheels 1112. The conveyor belt 1113 is wound around the drive wheel 1111 and the two driven wheels 1112, so that when the output shaft of the pressure motor 111a rotates, the drive wheel 1111 and the two driven wheels 1112 drive the conveyor belt 1113 to move, thereby driving the pressure wheel 112 to move closer to or away from the object to be scanned 110 through the conveyor belt 1113.
[0026] Furthermore, the clamping unit 11 in this embodiment also includes a transfer component 113, which is connected to the clamping drive mechanism 111 and the clamping wheel 112 respectively, so that the clamping drive mechanism 111 drives the clamping wheel 112 to move closer to or away from the object to be scanned 110 through the transfer component 113. In this embodiment, the transfer component 113 is connected to the conveyor belt 1113, so that the conveyor belt 1113 drives the transfer component 113 to move during the conveying process, thereby driving the clamping wheel to move closer to or away from the object to be scanned 110.
[0027] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 2 A schematic diagram of one embodiment in which the drive wheel 122 rotates the object to be scanned 110. Figure 5 yes Figure 2 A schematic diagram of another embodiment in which the drive wheel 122 drives the object to be scanned 110 to rotate. The drive unit 12 includes a rotation drive mechanism 121 and a drive wheel 122. The drive wheel 122 is used to clamp the object to be scanned 110 together with the clamping wheel 112. That is, when the scanning mechanism 10b needs to scan the identification code on the object to be scanned 110, as described above, the clamping drive mechanism 111 drives the clamping wheel 112 to approach the object to be scanned 110 so that the clamping wheel 112 and the drive wheel 122 clamp the object to be scanned 110 together. After the scanning is completed, the clamping drive mechanism 111 drives the clamping wheel 112 away from the object to be scanned 110 so that the clamping wheel 112 and the drive wheel 122 release the object to be scanned 110.
[0028] The rotary drive mechanism 121 is connected to the drive wheel 122 to drive the drive wheel 122 to rotate in the first direction B1 or the second direction B2, thereby causing the object to be scanned 110 to rotate in the second direction B2 or the first direction B1. The first direction B1 and the second direction B2 are opposite.
[0029] Specifically, the scanning mechanism 10b is used to scan the identification code on the object to be scanned 110 during its rotation. When the drive wheel 122 rotates in the first direction B1, the friction between the drive wheel 122 and the object to be scanned 110 causes the object to be scanned 110 to rotate in the second direction B2. Simultaneously, the friction between the object to be scanned 110 and the pressure wheel 112 causes the pressure wheel 112 to rotate in the first direction B1. While the object to be scanned 110 is rotating in the second direction B2, the scanning mechanism 10b can scan the identification code on the object to be scanned 110. However, in practical applications, if problems arise... Figure 4 The phenomenon of "identification code edge lifting" shown in M1, or as shown in... Figure 5 The phenomena of "identification code wrinkles and protrusions" shown in M2, or the phenomenon of "slippage of the object to be scanned 110", can cause the object to be scanned to be unable to rotate in the second direction B2, thereby causing the scanning operation of the scanning mechanism 10b to fail. In this embodiment, if these phenomena occur, the drive wheel 122 can be driven to rotate in the second direction B2 by the rotation drive mechanism 121, so as to drive the object to be scanned 110 to rotate in the first direction B1, thereby achieving "reverse rotation", avoiding the above-mentioned phenomena and avoiding the risk of scanning failure caused by these phenomena.
[0030] For ease of explanation, this embodiment uses Figure 4 Taking the phenomenon of "identification code edge lifting" as an example, such as Figure 4 As shown, due to the raised edge of the identification code, when the object to be scanned 110 rotates in the second direction B2, the raised edge will contact the pressure wheel 112b, causing the pressure wheel 112b to stop the object to be scanned 110, preventing the object to be scanned 110 from continuing to rotate in the second direction B2. At this time, if a "reverse rotation" is performed, the raised edge will not contact the pressure wheel 112b, but will be "flattened" by the pressure wheel 112a. Therefore, the object to be scanned 110 can continue to rotate in the first direction B1, and the scanning mechanism 10b can perform the scanning operation during the rotation of the object to be scanned 110.
[0031] Further reading Figure 2 and Figure 3 In this embodiment, the adapter component 113 includes an adapter 113a and an adapter bracket 113b. The adapter 113a is connected to the clamping drive mechanism 111. In this embodiment, the adapter 113 is connected to the conveyor belt 1113. The clamping wheel 112 is connected to the adapter bracket 113b. The adapter bracket 113b is movably mounted on the adapter 113a and elastically abuts against the adapter 113a. This allows the clamping wheel 112 to elastically clamp the object to be scanned 110 when the clamping wheel 112 and the drive wheel 122 are clamping it together. This reduces the rotational resistance between the clamping wheel 112 and the object to be scanned 110, and between the drive wheel 122 and the object to be scanned 110. It also avoids damage to the object to be scanned 110 caused by rigid clamping.
[0032] The adapter bracket 113b includes a bracket body 1131, a guide member 1132, and an elastic member 1133. The clamping wheel 112 is connected to the bracket body 1131. The guide member 1132 is slidably mounted on the adapter 113a and connected to the bracket body 1131. The elastic member 1133 abuts against the bracket body 1131 and the adapter 113a respectively.
[0033] Specifically, the clamping drive mechanism 111 drives the clamping wheel 112 in such a way as... Figure 3 As shown in the diagram, during the upward movement of A1 towards the object to be scanned 110, when the pressure roller 112 comes into contact with the object to be scanned 110, the bracket body 1131, under the action of this contact force, overcomes the elastic effect of the elastic element 1133 and drives the guide element 1132 to move as shown in the diagram. Figure 3 As shown, A2 slides upward relative to the adapter 113a until the clamping wheel 112, under the elastic action of the elastic member 1133, together with the drive wheel 122, clamps the object 110 to be scanned. After scanning is completed, the clamping drive mechanism 111 drives the clamping wheel 112 to... Figure 3As shown, A2 moves upward away from the object to be scanned 110, causing the clamping wheel 112 and the drive wheel 122 to release the object to be scanned 110. At this time, under the elastic action of the elastic element 1133, the bracket body 1131 drives the guide element 1132 to move as shown. Figure 3 A1, as shown, slides relative to the adapter 113a.
[0034] Optionally, the adapter bracket 113b also includes an anti-detachment component 1134. A guide component 1132 passes through the adapter 113a. The anti-detachment component 1134 is connected to the guide component 1132 on the side of the adapter 113a away from the bracket body 1131. With this arrangement, when, as described above, the guide component 1132... Figure 3 When A1 slides relative to the adapter 113a, the anti-detachment member 1134 can prevent the guide member 1132 from falling off the adapter 113a.
[0035] Please refer to the following: Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 6 yes Figure 2 A three-dimensional structural diagram of the first testing institution in China, 1141. Figure 7 yes Figure 2 A schematic diagram of the first state of the detection component 1142 moving upwards at A1. Figure 8 yes Figure 2 A schematic diagram of the second state of the detection component 1142 moving upwards at A1. Figure 9 yes Figure 2 The diagram shows the third state of the detection element 1142 moving upward in A1. The clamping unit 11 in this embodiment also includes a detection component 114. The detection component 114 includes a first detection mechanism 1141 and a detection element 1142. The detection element 1142 is connected to the adapter bracket 113a so that when the clamping wheel 112 approaches the object to be scanned 110, the first detection mechanism 1141 detects whether there is an object to be scanned 110 through the detection element 1142.
[0036] Specifically, the first detection mechanism 1141 includes a signal transmitting unit 114a and a signal receiving unit 114b. The signal transmitting unit 114a is used to transmit a detection signal, and the signal receiving unit 114b is used to receive the detection signal. The signal transmitting unit 114a and the signal receiving unit 114b are arranged opposite to each other and form a detection space 101. When the signal receiving unit 114b can receive the detection signal transmitted by the signal transmitting unit 114a, it indicates that the detection element 1142 is not located in the detection space 101. When the signal receiving unit 114b cannot receive the detection signal transmitted by the signal transmitting unit 114a, it indicates that the detection element 1142 is located in the detection space 101.
[0037] like Figure 7As shown, when the clamping roller 112 approaches the object to be scanned 110, the detection element 1142 also moves upward towards the object to be scanned 110 at A1. If there is no object to be scanned 110, the clamping roller 112 will not come into contact with the object to be scanned 110. Therefore, the detection element 1142 does not need to overcome the elasticity of the adapter bracket 113b to move upward at A2. At this time, if... Figure 8 As shown, the travel distance of the detection element 1142 after a preset time is L1. The detection element 1142 is not located within the detection space 101, and the signal receiving unit 114b can receive the detection signal emitted by the signal transmitting unit 114a. However, when there is an object 110 to be scanned, the detection element 1142 needs to overcome the elasticity of the adapter bracket 113b and move upwards at A2. At this time, as... Figure 9 As shown, the travel distance of the detection element 1142 after a preset time is L2. The detection element 1142 is located in the detection space 101. The signal receiving unit 114b cannot receive the detection signal emitted by the signal transmitting unit 114a. Therefore, the presence of the object to be scanned 110 can be detected by the above method.
[0038] Furthermore, the detection component 114 also includes a second detection mechanism 1143, which is used to detect whether the pressure roller 112 is at a preset starting position through the detection element 1142.
[0039] Understandably, the structure and detection principle of the second detection mechanism 1143 are the same as those of the first detection mechanism 1141. When the detection component 1142 causes the second detection mechanism 1143 to be unable to receive the detection signal, it indicates that the clamping wheel 112 is located at the preset starting position. Conversely, it indicates that the clamping wheel 112 is not located at the preset starting position. Through the setting of the second detection mechanism 1143, it is ensured that the clamping wheel 112 is located at the preset starting position when it is not close to the object to be scanned 110. This avoids the situation where the clamping wheel 112 moves too little when it is close to the object to be scanned 110, resulting in the inability to clamp the object to be scanned 110, or the clamping wheel 112 moves too much, resulting in the damage to the object to be scanned 110.
[0040] Please see Figure 10 , Figure 10 yes Figure 1 The control schematic diagram of the barcode scanning device 10 in this embodiment also includes a control unit 10c. The control unit 10c is communicatively connected to the pressing drive mechanism 111, the rotating drive mechanism 121 and the barcode scanning mechanism 10b. The control unit 10c is used to control the rotating drive mechanism 121 to rotate in the first direction B1 and to obtain the barcode scanning result of the barcode scanning mechanism 10b. The control unit 10c is also used to control the rotating drive mechanism 121 to drive the drive wheel 122 to rotate in the second direction B2 when the barcode scanning result does not contain an identification code.
[0041] For details on the specific principles of the control unit 10c, please refer to the above descriptions, which will not be repeated here.
[0042] This application also provides a sample analyzer, which includes a detection device and the barcode scanning device 10 in the above embodiments. The detection device is used to detect the sample to be tested placed in the object to be scanned 110.
[0043] It is understood that this embodiment does not limit the specific type of sample analyzer or the specific detection method of the detection device. For example, the sample analyzer can be an andrology, gynecology, blood, or other analyzers.
[0044] The beneficial effects of this application are as follows: Unlike the prior art, the rotating mechanism for scanning provided in this application includes: a clamping unit, including a clamping drive mechanism and a clamping wheel, wherein the clamping drive mechanism is connected to the clamping wheel to drive the clamping wheel to move closer to or away from the object to be scanned; and a driving unit, including a rotating drive mechanism and a driving wheel, wherein the driving wheel is used to clamp the object to be scanned together with the clamping wheel, and the rotating drive mechanism is connected to the driving wheel to drive the driving wheel to rotate in a first direction or a second direction, thereby causing the object to be scanned to rotate in the second direction or the first direction, wherein the first direction is opposite to the second direction. Compared with the prior art, this can avoid edge lifting, wrinkles, protrusions, or slippage, thus avoiding the risk of scanning failure caused by these phenomena.
[0045] The above description is only a partial embodiment of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the scope of patent protection of this application.
