Abstract
Description
Technical Field
[0001] The utility model relates to the field of infusion set assembly equipment, in particular to an infusion hose alignment device. Background Art
[0002] An infusion set is a medical supply composed of components such as a venous needle, an infusion hose, a medicine filter, a flow regulator, a drip chamber, and a bottle stopper puncture device. An infusion set assembly equipment is a device for assembling each component of an infusion set into a complete infusion set. The hose conveying device of the infusion set assembly equipment uses a clamping bracket to convey the infusion hose. The hose conveying device is in a runway shape, and the assembly devices of each component of the infusion set assembly equipment are orderly distributed around the hose conveying device. After the hose conveying device conveys the infusion hose to the corresponding station, the infusion hose will complete the assembly with the component under the action of the assembly device at this station.
[0003] During the actual conveying of the hose by the hose conveying device, due to the limited length of the clamping bracket of the hose conveying device, the clamping bracket can only clamp one end of the infusion hose, and the other end of the infusion hose can only be scattered outside the clamping bracket. Due to the soft nature of the infusion hose itself, the scattered state of the scattered end of each infusion hose is different. When a large number of clamping arms are used to clamp the scattered ends of a large number of infusion hoses, the scattered ends of some infusion hoses are not within the clamping range of the clamping arms due to their deviated positions, resulting in some clamping arms being unable to pick up the infusion hose to complete the assembly work between the infusion hose and other components, thus affecting the assembly quality. Moreover, the infusion hoses picked up by a large number of clamping arms are also prone to having the end faces of the scattered ends of each infusion hose not being in the same plane due to inconsistent scattered states, affecting the assembly quality when the infusion hose is assembled with other components.

[0035] The usage method of the present utility model is as follows:
[0036] The clamping frame 6 of the hose conveying device can be used to clamp the rear end of the infusion hose. When the hose conveying device transports the clamping frame 6 to the position of the infusion hose alignment device along its own runway track, the front end of the infusion hose not clamped by the clamping frame 6 is scattered directly above the front tooth grooves 518 and the rear tooth grooves 513. At this time, the lifting cylinder 510 is started, and the piston rod of the lifting cylinder 510 will drive the fixed straightening plate 503 and the movable straightening plate 504 to move up synchronously. When the fixed straightening plate 503 and the movable straightening plate 504 move up to a height corresponding to the clamping frame 6, the lifting cylinder 510 stops running. At this time, the suspended part of the infusion hose falls into the front tooth grooves 518 and the rear tooth grooves 513 at the same time. The front tooth grooves 518 are formed by the gaps between adjacent front straightening teeth 517, and the rear tooth grooves 513 are formed by the gaps between adjacent rear straightening teeth 512. Both the front straightening teeth 517 and the rear straightening teeth 512 are triangular. Therefore, the groove widths of the front tooth grooves 518 and the rear tooth grooves 513 increase from bottom to top. This structural design facilitates the rapid falling of the infusion hose into the front tooth grooves 518 and the rear tooth grooves 513.
[0037] When the suspended part of the infusion hose falls onto the bottom of the front tooth groove 518 and the rear tooth groove 513, the first cylinder 506 can be activated. At this time, the piston rod of the first cylinder 506 will drive the right slide plate 507 to move forward along the track of the first slide rail 502. When the right slide plate 507 moves forward, the fixed straightening plate 503 and the movable straightening plate 504 move forward synchronously. During the forward movement, the fixed straightening plate 503 and the movable straightening plate 504 will straighten the originally scattered front end of the infusion hose. After the fixed straightening plate 503 and the movable straightening plate 504 move forward a certain stroke, the first cylinder 506 stops running. At this time, the infusion hose has been straightened to a certain extent and is no longer as scattered as before. And at this moment, the heights of the front tooth groove 518 and the rear tooth groove 513 are higher than the height of the auxiliary tooth groove 416. Then, the moving cylinder 514 can be opened. When the piston rod of the moving cylinder 514 drives the support plate 516 to move forward through the second guide plate 515, the movable straightening plate 504 moves forward synchronously. After the movable straightening plate 504 moves forward, the distance between the support point formed by the movable straightening plate 504 and the support point formed by the fixed straightening plate 503 becomes larger. At this time, the infusion hose is further straightened. When the movable straightening plate 504 moves forward to the actual required position, the moving cylinder 514 stops running.
[0038] Immediately afterwards, the second cylinder 404 can be started. At this time, the piston rod of the second cylinder 404 will drive the left slide plate 406 to stably move backward along the track of the second slide rail 403. When the left slide plate 406 moves backward, the support plate 414 moves backward synchronously. When the support plate 414 moves to directly below the front end of the infusion hose that has been straightened to a certain extent, the second cylinder 404 stops operating, and the lifting cylinder 409 starts operating. The piston rod of the lifting cylinder 409 will drive the lifting plate 411 to move upward through the third guide plate 410, thereby realizing the upward movement of the support plate 414. When the support plate 414 moves upward to the actual required height, the straightened front end of the infusion hose falls into the arc-shaped groove 417 at the bottom of the auxiliary tooth groove 416. At this moment, the front end of the infusion hose protrudes forward outside the arc-shaped groove 417, and the length of the front end of the infusion hose protruding outside the arc-shaped groove 417 is about 10 millimeters. At this moment, the lifting cylinder 409 stops operating, and the third cylinder 412 starts operating. The piston rod of the third cylinder 412 will drive the alignment plate 413 to move backward. In the case where the ends of all infusion hoses are not aligned, the rear side wall of the alignment plate 413 will first come into contact with the front end of the infusion hose with a smaller distance from it. As the alignment plate 413 continues to move backward, finally, the rear side wall of the alignment plate 413 fits against the front side wall of the support plate 414. At this moment, the front end faces of all infusion hoses are in contact with the rear side wall of the alignment plate 413, thereby realizing the alignment of the front ends of all infusion hoses. When the front ends of all infusion hoses are aligned, the original 10-millimeter length that protruded outside the arc-shaped groove 417 will appear at the rear of the infusion hose, which is convenient for the gripper of the material transfer mechanism on other assembly devices to clamp the rear end of the infusion hose when assembling the rear end of the infusion hose with other components. At the same time, the infusion device assembly equipment is a relatively complex equipment with multiple assembly devices, and several of these assembly devices will work together. Therefore, when the rear end of the infusion hose is assembled later, there will also be other assembly devices assembling the front end of the infusion hose. The missing 10 millimeters at the front end of the infusion hose can effectively avoid the assembly actions of other assembly devices and prevent incorrect installation.
[0039] When the front ends of all the infusion hoses are aligned, the fifth cylinder 304 can be activated. The piston rod of the fifth cylinder 304 can drive the pneumatic finger mounting plate 305 to move downward. When the upper end of the piston rod of the sixth cylinder 306 is connected to the lower end of the piston rod of the fifth cylinder 304 through a coupling, the stroke of the downward movement of the pneumatic finger mounting plate 305 can be effectively increased. When the pneumatic finger mounting plate 305 moves downward, all the pneumatic fingers 307 move downward synchronously. When the pneumatic fingers 307 move downward to the actual required position, the clamping arms 308 on the clamping jaws on both the left and right sides of the pneumatic fingers 307 are just located on both the left and right sides of the infusion hose and behind the support plate 414. At this moment, the guide strip 315 presses on the upper surface of the infusion hose, and the arc-shaped groove 417 at the bottom of the auxiliary tooth groove 416 supports the lower surface of the infusion hose, so that both the upper and lower sides of the infusion hose can be limited, further ensuring the neatness when the infusion hose is pressed and aligned by the alignment plate 413. When the front ends of all the infusion hoses are aligned, the pneumatic fingers 307 can be activated. At this time, the pneumatic fingers 307 will control the clamping arms 308 on the clamping jaws on both the left and right sides to move closer to clamp the front ends of the infusion hoses.
[0040] After the front ends of the infusion hoses are clamped, the fifth cylinder 304 can be activated again. The fifth cylinder 304 and the sixth cylinder 306 drive the infusion hoses to move upward to the assembly height, and then the fourth cylinder 203 is used to move the infusion hoses forward or backward, so as to transfer the infusion hoses to other devices for the assembly of the infusion hoses and other components, or directly complete the assembly work by using the forward or backward force of the fourth cylinder 203.
[0041] As described above, it can be seen that the utility model can not only initially straighten the originally heat-dissipating part of the infusion hoses through the fixed straightening plate 503 and the movable straightening plate 504, but also ensure that all the infusion hoses fall into the front tooth grooves 518 and the rear tooth grooves 513, so that the positions of all the infusion hoses after initial straightening can correspond to the positions of the auxiliary tooth grooves 416 on the support plate 414, which is convenient for the ends of the infusion hoses to accurately fall into the auxiliary tooth grooves 416 later and be aligned by the alignment plate 413, effectively avoiding the situation that due to the inconsistent scattered states of each infusion hose, some of the infusion hoses cannot accurately fall into the auxiliary tooth grooves 416, resulting in a reduction in the number of infusion hoses that can ultimately be assembled, and thus effectively avoiding the situation that the reduction in the number of infusion hoses that can be assembled in batches leads to a decrease in the assembly efficiency, effectively ensuring the assembly efficiency. At the same time, when batch assembling with other components with the ends of each infusion hose aligned, it can ensure that the assembly results of each infusion hose are consistent, and to the greatest extent ensure the assembly quality between the infusion hoses and other components.
[0042] The front side walls of several pneumatic fingers 307 are connected by an adapter plate 309. A pressure plate 310 is provided on the front side wall of the adapter plate 309. The presence of the pressure plate 310 can further limit the upper surface of the infusion hose when the front end of the infusion hose is aligned by the alignment plate 413, thereby further ensuring the stability when the pressure plate 310 is aligned. When the pressure plate 310 moves down with the pneumatic finger 307, it just falls into the gap between the support plate 414 and the alignment plate 413, ensuring the stability of the alignment plate 413 when aligning all infusion hoses to the greatest extent. Symmetric screw holes are provided on the left and right sides of the front side wall of the adapter plate 309. Long circular holes 312 corresponding to the positions of the screw holes are provided on the upper part of the pressure plate 310. Just passing a screw through the long circular hole 312 and screwing it into the screw hole can fix the pressure plate 310 to the adapter plate 309, and the presence of the long circular holes 312 facilitates the adjustment of the height of the pressure plate 310.
[0043] A detection strip 418 is provided on the rear side wall of the support plate 414. A number of detection grooves 419 corresponding to the positions of the arc grooves 417 are provided on the upper surface of the detection strip 418. An optical fiber probe mounting hole 420 is provided at the bottom of the detection groove 419. An auxiliary plate 421 is provided on the rear side wall of the detection strip 418. A number of guiding notches 422 corresponding to the positions of the detection grooves 419 are provided on the auxiliary plate 421. The width of the guiding notches 422 gradually decreases from top to bottom. In the actual use process, each pneumatic finger is independently controlled. The optical fiber probe mounting hole 420 is for an optical fiber probe. The optical fiber probe is the front-end component of an existing optical fiber sensor, used to receive signals and can feedback information to the optical fiber sensor after detecting the corresponding object. When the optical fiber detection probe detects the infusion hose, if the infusion hose corresponding to the optical fiber probe mounting hole 420 does not fall into the arc groove, the corresponding pneumatic finger 307 does not work. The guiding notches 422 on the auxiliary plate 421 can play an auxiliary guiding role when the infusion hose falls into the arc groove 417, ensuring that each arc groove at the bottom of the auxiliary tooth grooves 416 has an infusion hose to the greatest extent.
[0044] The fixing mechanism 1 includes a left support beam 101 located above the left seat plate 401. A right support beam 102 is provided on the right side of the left support beam 101. The front ends between the left support beam 101 and the right support beam 102 and the rear ends between the left support beam 101 and the right support beam 102 are both connected by a connecting beam 103. A number of uniformly distributed columns 104 are provided on the lower surfaces of the left support beam 101 and the right support beam 102. This fixing method can not only ensure stability but also facilitate the movement and work of other mechanisms.
