Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a blood collection tube pitch-changing mechanism. Background Technology

[0002] In existing technology, a conveyor line transports multiple blood collection tubes. After being transported to a designated position, the tubes are pushed by a pushing mechanism to a receiving mechanism for receiving. Then, a robotic arm transports the blood collection tubes to a labeling mechanism for labeling. Because the labeling mechanism has specific requirements for the spacing between the blood collection tubes, the existing receiving mechanism cannot directly adjust the spacing between multiple blood collection tubes. An additional adjustment mechanism is needed to adjust the spacing, which not only increases production costs and time but also reduces production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a blood collection tube spacing adjustment mechanism. This blood collection tube spacing adjustment mechanism not only realizes the material receiving operation, but also realizes the adjustment of the spacing of the blood collection tubes, thereby improving production efficiency and saving production costs and time costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a blood collection tube pitch-changing mechanism, including a first driving mechanism, a second driving mechanism, a sliding plate and a plurality of contour positioning seats. The leftmost contour positioning seat is fixedly installed on the sliding plate, and the remaining plurality of contour positioning seats are slidably engaged with the sliding plate through a sliding assembly. The plurality of contour positioning seats are at the same height. The driving end of the first driving mechanism is connected to the sliding plate, and the second driving mechanism is installed on the sliding plate. The first driving mechanism is used to drive the sliding plate to move the contour positioning seats and the second driving mechanism horizontally.

[0005] A telescopic component is provided between two adjacent contour positioning seats. The driving end of the second driving mechanism is connected to the rightmost contour positioning seat. The second driving mechanism is used to drive the rightmost contour positioning seat to move multiple contour positioning seats horizontally, so that multiple telescopic components are at equal distances.

[0006] In one embodiment, the telescopic component of the blood collection tube pitch mechanism is a linkage assembly, which includes a first linkage and a second linkage. One end of the first linkage is hinged to an adjacent contour positioning seat, the other end of the first linkage is hinged to one end of the second linkage, and the other end of the second linkage is hinged to another adjacent contour positioning seat.

[0007] In one embodiment, the second drive mechanism of the blood collection tube pitch mechanism is a third cylinder. The drive end of the third cylinder is connected to the rightmost contour positioning seat. The third cylinder drives the rightmost contour positioning seat to move horizontally, so that multiple contour positioning seats move horizontally along the sliding plate.

[0008] In one embodiment, the first driving mechanism of the blood collection tube pitch mechanism is a linear module. The driving end of the linear module is connected to the sliding plate, and the linear module drives the sliding plate to move horizontally. The sliding plate is provided with through holes for the telescopic component to extend and retract.

[0009] In one embodiment, the blood collection tube pitch-changing mechanism further includes a conveyor line for conveying the blood collection tubes and a pushing mechanism for pushing the blood collection tubes onto the contour positioning seat. The conveyor line is located on one side of the sliding block, and the pushing mechanism is located on the side of the conveyor line away from the sliding block. The conveyor line includes a frame, a drive sprocket, a driven sprocket, and a conveyor chain wound around the drive sprocket and the driven sprocket. The drive sprocket and the driven sprocket are rotatably mounted at both ends of the frame, and a plurality of conveyor rollers are rotatably arranged on the conveyor chain at intervals, forming a receiving position for placing the blood collection tubes between adjacent conveyor rollers.

The second cylinder is mounted on the mounting base, and the drive end of the second cylinder is connected to the feeding plate. The second guide assembly is horizontally mounted on the mounting base, and the moving end of the second guide assembly is connected to the feeding plate. The second cylinder is used to drive the feeding plate to move horizontally along the second guide assembly to perform the feeding operation.

[0011] In one embodiment, a photoelectric sensor is provided on one side of the conveyor line of the blood collection tube variable distance mechanism. The photoelectric sensor is used to detect the number of blood collection tubes that have reached the designated position.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 4 As shown, an embodiment of this application provides a blood collection tube pitch-changing mechanism, including a first driving mechanism 1, a second driving mechanism 2, a sliding plate 3, and multiple contour positioning seats 4. The leftmost contour positioning seat 4 is fixedly installed on the sliding plate 3, and the remaining multiple contour positioning seats 4 are slidably engaged with the sliding plate 3 through a sliding assembly. The multiple contour positioning seats 4 are at the same height. The driving end of the first driving mechanism 1 is connected to the sliding plate 3, and the second driving mechanism 2 is installed on the sliding plate 3. The first driving mechanism 1 is used to drive the sliding plate 3 to move the contour positioning seats 4 and the second driving mechanism 2 horizontally.

[0022] A telescopic component 5 is provided between two adjacent contour positioning seats 4. The driving end of the second driving mechanism 2 is connected to the rightmost contour positioning seat 4. The second driving mechanism 2 is used to drive the rightmost contour positioning seat 4 to move multiple contour positioning seats 4 horizontally, so that multiple telescopic components 5 are at equal distances.

[0023] Specifically, when the conveyor line 6 delivers multiple blood collection tubes to the designated position, the first drive mechanism 1 drives the sliding plate 3 to move multiple contour positioning seats 4 to the designated position. The second drive mechanism 2 drives the rightmost contour positioning seat 4 to pull the remaining contour positioning seats horizontally, while the leftmost contour positioning seat 4 remains fixed, ensuring that the telescopic component 5 between adjacent contour positioning seats 4 is at its maximum extension limit, thus ensuring equal distance adjustment between adjacent contour positioning seats 4. After the pushing mechanism 7 pushes the multiple blood collection tubes on the conveyor line 6 onto the multiple contour positioning seats 4, the second drive mechanism 2 drives the rightmost contour positioning seat 4 to reset the remaining contour positioning seats 4, causing adjacent contour positioning seats 4 to abut together, thus forming the gap required for labeling between the blood collection tubes on the contour positioning seats 4.

[0024] In the above structure, by setting up a first drive mechanism 1, a second drive mechanism 2, a sliding plate 3, and multiple positioning seats in cooperation, the receiving and spacing adjustment of multiple blood collection tubes is realized. This blood collection tube spacing adjustment mechanism not only realizes the receiving operation, but also realizes the adjustment of the spacing of the blood collection tubes, thereby improving production efficiency and saving production and time costs.

[0025] like Figure 2 and Figure 4 As shown, in one embodiment, the telescopic component 5 of the blood collection tube pitch-changing mechanism is a linkage assembly, which includes a first linkage 51 and a second linkage 52. One end of the first linkage 51 is hinged to an adjacent contour positioning seat 4, and the other end of the first linkage 51 is hinged to one end of the second linkage 52. The other end of the second linkage 52 is hinged to another adjacent contour positioning seat 4. When the second drive mechanism 2 pulls the rightmost contour positioning seat 4 to a designated position, the first linkage 51 and the second linkage 52 between the two adjacent contour positioning seats 4 are in a horizontal state, maintaining the maximum pulling distance. When the second drive mechanism drives the rightmost contour positioning seat 4 to move in the opposite direction to reset, the first linkage 51 and the second linkage 52 are in an abutting state, causing the two adjacent contour positioning seats 4 to abut together. This arrangement facilitates equal-distance pitch-changing adjustment between the two adjacent contour positioning seats 4.

[0026] like Figure 2 As shown, in one embodiment, the second drive mechanism 2 of the blood collection tube pitch-changing mechanism is a third cylinder. The drive end of the third cylinder is connected to the rightmost contour positioning seat 4. The third cylinder drives the rightmost contour positioning seat 4 to move horizontally, causing multiple contour positioning seats 4 to move horizontally along the sliding plate 3. This arrangement, in conjunction with the telescopic component 5, facilitates the driving of multiple contour positioning seats 4 to move at equal distances.

[0027] like Figure 2As shown, in one embodiment, the first drive mechanism 1 of the blood collection tube distance adjustment mechanism is a linear module. The drive end of the linear module is connected to the sliding plate 3, and the linear module drives the sliding plate 3 to move horizontally. The sliding plate 3 is provided with a through hole for the telescopic component 5 to extend and retract. This linear module can drive the sliding plate 3 to move multiple contoured positioning seats 4 horizontally along the moving direction of the conveyor line 6. When the second drive mechanism 2 drives the slider assembly to adjust the distance of the multiple contoured positioning seats 4, the telescopic component 5 extends and retracts through the through hole of the sliding plate 3. The linear module improves the moving efficiency. The through hole facilitates the movement of the telescopic component 5 within the through hole and does not cause interference.

[0028] like Figure 1 As shown, in one embodiment, the blood collection tube pitch-changing mechanism further includes a conveyor line 6 for conveying blood collection tubes and a pushing mechanism 7 for pushing blood collection tubes onto the contour positioning seat 4. The conveyor line 6 is located on one side of the sliding block, and the pushing mechanism 7 is located on the side of the conveyor line 6 away from the sliding block. The conveyor line 6 includes a frame 61, a second motor, a drive sprocket 63, a driven sprocket, and a conveyor chain 65 wound around the drive sprocket 63 and the driven sprocket. The drive sprocket 63 and the driven sprocket are respectively rotatably mounted at both ends of the frame 61. A plurality of conveyor rollers 66 are rotatably arranged on the conveyor chain 65 at intervals. A receiving position for placing blood collection tubes is formed between adjacent conveyor rollers 66. The drive end of the second motor is connected to the drive sprocket 63, and the second motor drives the drive sprocket 63 to drive the driven sprocket and the conveyor chain 65 to rotate. Multiple blood collection tubes are fed into the receiving positions of multiple conveying rollers 66. A second motor drives the drive sprocket 63 to rotate the driven sprocket and the conveying chain 65. The conveying chain 65 drives the multiple conveying rollers 66 and the multiple blood collection tubes to move. This arrangement facilitates the conveying of multiple blood collection tubes and ensures the stability and effectiveness of the conveying process.

[0029] like Figure 1As shown, in one embodiment, the feeding mechanism 7 of the blood collection tube variable distance mechanism includes a base plate 71, a first cylinder 72, a mounting base 73, a second cylinder 74, a second guide assembly 75, and a feeding plate 76. The base plate 71 is mounted on the frame 61. The first cylinder 72 is mounted on the base plate 71, and the driving end of the first cylinder 72 is connected to the mounting base 73. A first guide assembly 77 is vertically arranged between the base plate 71 and the mounting base 73. The first cylinder 72 is used to drive the mounting base 73 to move up and down along the first guide assembly 77. The second cylinder 74 is mounted on the mounting base 73, and the driving end of the second cylinder 74 is connected to the feeding plate 76. The second guide assembly 75 is horizontally mounted on the mounting base 73, and the moving end of the second guide assembly 75 is connected to the feeding plate 76. The second cylinder 74 is used to drive the feeding plate 76 to move horizontally along the second guide assembly 75 to perform the feeding operation. The first cylinder 72 drives the mounting base 73, which in turn moves the second cylinder 74 and the pusher plate 76 up and down. Adjusting the height of the pusher plate 76, the second cylinder 74 drives the pusher plate 76 to move towards the blood collection tube, pushing the blood collection tube onto the contour positioning seat 4. This design facilitates pushing the blood collection tube onto the contour positioning seat 4, improving the stability and effectiveness of the pushing process.

[0030] like Figure 1 As shown, in one embodiment, a photoelectric sensor 67 is provided on one side of the conveyor line 6 of the blood collection tube pitch-changing mechanism. The photoelectric sensor 67 is used to detect the number of blood collection tubes reaching the designated position. The photoelectric sensor 67 detects the blood collection tubes on the conveyor line 6. When a certain number of blood collection tubes pass the photoelectric sensor 67, the photoelectric sensor 67 sends a stop signal to the conveyor line 6, and then proceeds to the next material receiving operation. This arrangement facilitates the detection of the number of blood collection tubes.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
