Description

Technical Field

[0001] This utility model relates to the field of assembly and processing technology, specifically to a blood collection tube cap device for an automatic assembly line. Background Technology

[0002] Blood collection tubes, as core instruments for blood sample collection, transportation, and preservation, have a wide range of applications and are used in large quantities. With the rapid development of the medical industry and the continuous growth of testing needs, the production scale of blood collection tubes is expanding day by day, and the requirements for production efficiency and quality of blood collection tubes are also increasing. The assembly of the cap and the blood collection tube is a key link in the production process of blood collection tubes.

[0003] Current blood collection tube cap assembly equipment generally suffers from complex positioning mechanisms and low assembly alignment accuracy. It relies on multiple sets of sensors and complex mechanical structures to achieve the alignment of blood collection tubes and caps, which not only increases equipment costs but also leads to low assembly efficiency due to the time-consuming positioning process. Some automated equipment is prone to misalignment of blood collection tubes and caps during the transportation process, requiring manual intervention for calibration, which makes it difficult to meet the high efficiency and stability requirements of large-scale production. Utility Model Content

[0004] The purpose of this utility model is to provide a blood collection tube cap device for an automatic assembly line, which solves the problem mentioned in the background art that traditional assembly equipment requires multiple sets of sensors and complex mechanical structures to achieve the alignment of blood collection tubes and caps, which not only increases equipment costs, but also leads to low assembly efficiency due to positioning time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blood collection tube cap device for an automatic assembly line, comprising two sliding frames and an assembly base. The two sliding frames are kept parallel vertically, and a plurality of sliding rings are slidably connected to the inner side of each sliding frame. Two synchronizing rods are fixedly connected between the upper and lower sliding rings. The two synchronizing rods pass through the two end surfaces of a limiting block and are slidably connected to the limiting block. A blood collection tube body is engaged with the inner side of the limiting block, and a cap body is inserted into the surface of the sliding ring directly above the blood collection tube body.

[0006] In this technical solution, two sliding frames are set up to transport the blood collection tube body and the cap body respectively, and each set of sliding rings is connected by a synchronous rod to ensure that the two are always on the same vertical line during the transport process. This ensures that subsequent assembly can be quickly achieved by pressing, without the need for complex mechanical positioning. The two can be accurately aligned by mechanical linkage alone, effectively shortening the single assembly positioning time and significantly improving the efficiency of the assembly line operation.

[0007] Preferably, a spring is sleeved on the surface of the synchronizing rod directly above the limiting block, and a fixing block is fixedly connected to the surface of one of the synchronizing rods, the fixing block being located below the limiting block.

[0008] Preferably, the mounting base is located on one side of the two sliding frames, and a servo motor is fixedly connected to the outer wall of the mounting base. The tail end of the drive shaft of the servo motor is connected to the gear inside the mounting base through a coupling.

[0009] Preferably, a first support frame and a second support frame are respectively provided on the left and right sides of the gear. The side walls of the first support frame and the second support frame are provided with a number of equidistant protrusions. The gear meshes with the protrusions. One end of the first support frame and the second support frame are located inside their respective telescopic frames and are slidably connected to the telescopic frames. The telescopic frames are fixedly connected inside the mounting base. The other ends of the first support frame and the second support frame are located directly above the cover body and directly below the blood collection tube body, respectively.

[0010] Preferably, a side plate is fixedly connected to the side wall of the mounting base directly above the sliding frame, and an electric push rod is fixedly connected to the top of the side plate. The telescopic end of the electric push rod passes through the side plate and is fixedly connected to the stop block.

[0011] Preferably, a transmission belt assembly is provided directly below the sliding frame on both sides of the mounting base, and a number of equidistant protrusions are fixedly connected to the surface of the transmission belt assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses two sliding frames to transport the blood collection tube body and the cap body respectively, and each set of sliding rings is connected by a synchronous rod, so as to ensure that the two are always on the same vertical line during the transport process. This ensures that subsequent assembly can be quickly achieved by pressing, without the need for complex mechanical positioning. The precise alignment of the two can be achieved by mechanical linkage alone, effectively shortening the single assembly positioning time and significantly improving the efficiency of assembly line operation.

[0014] 2. This utility model sets a No. 1 support frame and a No. 2 support frame on the upper and lower sides of the cover body and the blood collection tube body, respectively. During assembly, the blood collection tube body is lifted up and the cover body is pressed down, so that the blood collection tube body directly contacts the cover body from below. At this time, the cover body can be pressed directly without deliberate alignment, eliminating the offset problem caused by traditional one-sided pressing, improving the assembly qualification rate, and eliminating the need for manual calibration.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A blood collection tube cap device for an automated assembly line, see [link / reference] Figures 1 to 3 The system includes two sliding frames 2 and an assembly base 9. The two sliding frames 2 are parallel vertically, and several sliding rings 3 are slidably connected to the inner side of each sliding frame 2. Two synchronous rods 4 are fixedly connected between the upper and lower sliding rings 3. The sliding rings 3 are connected by the synchronous rods 4 to ensure that they are always on the same vertical line during transport. A spring 6 is sleeved on the surface of the synchronous rod 4 directly above the limit block 5. A fixing block 7 is fixedly connected to the surface of one of the synchronous rods 4. The fixing block 7 is located below the limit block 5. The two synchronous rods 4 pass through the two ends of the limit block 5 and are slidably connected to the limit block 5. The blood collection tube body 8 is clamped to the inner side of the limit block 5. 5. Made of non-plastic material, it has a certain degree of elasticity, so the blood collection tube body 8 can be directly pressed into the interior of the limiting block 5. The sliding ring 3 directly above the blood collection tube body 8 has a cover body 801 inserted into it. The cover body 801 is made of rubber and can be fixed in the center hole of the limiting ring by friction, making it easy to be pressed out. During assembly, the blood collection tube body 8 rises together with the limiting block 5 and quickly contacts the bottom of the upper limiting ring. The cover body 801 directly contacts the top of the blood collection tube body 8 and aligns with it during pressing. At this time, no special positioning components are needed to assist in positioning, and quick pressing assembly can be completed, which improves the assembly efficiency.

[0022] Specifically, the mounting base 9 is located on one side of the two sliding frames 2. A servo motor 10 is fixedly connected to the outer wall of the mounting base 9. The tail end of the drive shaft of the servo motor 10 is connected to the gear 11 inside the mounting base 9 via a coupling. A first support frame 12 and a second support frame 13 are respectively provided on the left and right sides of the gear 11. The side walls of the first support frame 12 and the second support frame 13 are provided with several equidistant protrusions 111. The gear 11 meshes with the protrusions 111. One end of the first support frame 12 and the second support frame 13 is located inside their respective telescopic frames 14 and is slidably connected to the telescopic frames 14. The telescopic frames 14 are fixedly connected inside the mounting base 9. The other ends of support frame 12 and support frame 13 are located directly above the cover body 801 and directly below the blood collection tube body 8, respectively. During assembly, when the sliding ring 3 reaches the assembly seat 9, the servo motor 10 starts and drives the gear 11 to rotate. At this time, support frame 12 and support frame 13 will move relative to each other. Support frame 12 moves down and presses the cover body 801, while support frame 13 moves up and lifts the blood collection tube body 8, so that the two can move closer to each other, making the assembly more precise and improving the assembly efficiency. It should be noted that support frame 12 and support frame 13 can pass smoothly through the round hole in the center of the sliding ring 3 to ensure the normal operation of the assembly.

[0023] It is worth noting that, such as Figure 1 As shown, a side plate 15 is fixedly connected to the side wall of the mounting base 9 directly above the sliding frame 2. An electric push rod 151 is fixedly connected to the top of the side plate 15. The telescopic end of the electric push rod 151 passes through the side plate 15 and is fixedly connected to the stop block 152. During assembly, in order to allow the cover body 801 to reach exactly below the first support frame 12, the electric push rod 151 on the side plate 15 is set to a certain degree and extends and retracts at regular intervals, causing the stop block 152 to move down. The insert below the stop block 152 will be inserted into the gap between the two sliding rings 3, so that the sliding rings 3 will not continue to slide during assembly. After the assembly is completed, the electric push rod 151 will drive the stop block 152 to rise, releasing the movement path of the sliding rings 3.

[0024] It is worth noting that, such as Figure 1 As shown, a transmission belt assembly 1 is provided directly below the sliding frame 2 on both sides of the assembly base 9. Several equally spaced protrusions 101 are fixedly connected to the surface of the transmission belt assembly 1. The distance between the protrusions 101 is the same as the distance between two adjacent sliding rings 3. The protrusions 101 are located inside the circular hole of the sliding ring 3 directly above. Therefore, during the movement of the transmission belt assembly, the protrusions 101 drive the sliding ring 3 to move laterally. When it reaches the assembly base 9, the protrusions 101 disengage from the sliding ring 3, allowing the sliding ring 3 to smoothly reach the assembly base 9 for assembly.

[0025] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
