In the present embodiment, the linear guide rails 31, 32 are arranged in a substantially horizontal direction, so that the traveling drive mechanism drives the probe holder 2 to move in a horizontal direction with respect to the pinch roller 42, and the belt drive mechanism 4 is positioned above the traveling drive mechanism, that is, in the present cam mechanism, the roller 23 is pinched against the curved guide surface 240 by the gravity of the belt drive mechanism 4 itself.
The specific process for erasing the couplant of the ultrasonic probe 01 comprises the following steps:
(1) The travel driving mechanism is controlled to drive the probe fixing seat 2 to travel to a loading and unloading station outside the box opening 100 along the linear guide rails 31 and 32, namely, the position of the travel switch 34 is triggered, so that an operator can conveniently place the used ultrasonic probe 01 on the profiling inflation bag 26, and then the profiling inflation bag 26 is inflated to clamp and fix the ultrasonic probe 01 on the probe fixing seat 2; at this point, the roller 23 is pressed against the straight section 241.
(2) The control travel driving mechanism drives the probe fixing seat 2 to travel into the box opening 100 along the linear guide rails 31 and 32 and start to enter the erasing station, namely the ultrasonic probe 01 is positioned at the front lower position of the compacting roller 42; at this time, the roller 23 presses against the abutment of the straight face segment 241 and the outer convex smooth face segment 242; during this process, the vertical spacing of pinch roller 42 from ultrasonic probe 01 remains constant as roller 23 moves along straight section 241.
(3) The travel driving mechanism is controlled to drive the probe fixing seat 2 to continue traveling along the linear guide rails 31 and 32, as shown in fig. 10, the roller 23 is pressed on the convex smooth surface section 242, so that the couplant erasing belt 47 pressed on the outer peripheral surface of the roller is pressed on the front end surface part 010 of the ultrasonic probe 01, at the moment, the ultrasonic probe 01 compresses the elastic pressing roller 42 to deform and embed the contact part of the elastic pressing roller 42, so that the part of the couplant erasing belt contacted with the ultrasonic probe 01 is wrapped on the front end surface part 010, namely, at the moment, the minimum distance between the rotation axis of the pressing roller 41 and the surface of the ultrasonic probe 01 is smaller than the radius of the pressing roller 42; and the couplant attached to the portion is subjected to the erasing process by the relative displacement between the couplant erasing belt 47 and the ultrasonic probe 01.
(4) The driving mechanism is controlled to drive the probe fixing seat 2 to continue to travel along the linear guide rails 31 and 32, as shown in fig. 11, the roller 23 is pressed on the concave smooth surface section 243 to enable the couplant erasing belt 47 pressed on the outer peripheral surface to travel from being pressed on the front end surface 010 to being pressed on the middle end surface 011 of the ultrasonic probe 01, in the process, the minimum distance between the rotating axis of the pressing roller 42 and the surface of the ultrasonic probe 01 is smaller than the radius of the pressing roller 42, and at the moment, the ultrasonic probe 01 compresses the pressing roller 42 to enable the contact part of the pressing roller 42 to be deformed and embedded, so that the contact part of the couplant erasing belt is wrapped on the middle end surface 011; and erases the couplant attached to the portion by a relative displacement between the couplant erasure belt 47 and the ultrasonic probe 01.
(5) The driving mechanism is controlled to drive the probe fixing seat 2 to continue to travel along the linear guide rails 31 and 32, as shown in fig. 12, the roller 23 is pressed on the convex smooth surface section 244 so that the couplant erasing belt 47 pressed on the outer peripheral surface of the roller is driven to travel from being pressed on the middle end face section 011 to being pressed on the rear end face section 012 of the ultrasonic probe 01, in the process, the minimum distance between the rotating axis of the pressing roller 42 and the surface of the ultrasonic probe 01 is smaller than the radius of the pressing roller 42, and at the moment, the ultrasonic probe 01 compresses the pressing roller 42 to deform and embed the contact part of the pressing roller 42 so that the contact part of the couplant erasing belt is wrapped on the rear end face section 012; and erases the couplant attached to the portion by a relative displacement between the couplant erasure belt 47 and the ultrasonic probe 01.
(6) The travelling driving mechanism is controlled to drive the probe fixing seat 2 to continue travelling along the linear guide rails 31 and 32, the roller 23 is pressed on the straight surface section 244 and is separated from contact with the ultrasonic probe 01, and the ultrasonic probe 01 is caused to travel to be positioned right below the ultraviolet lamp 51, namely enters a disinfection station; the vertical spacing of pinch roller 42 from ultrasonic probe 01 remains constant during movement of roller 23 along straight segment 245. And controls the ultraviolet lamp 51 to operate to perform ultraviolet irradiation sterilization and disinfection on the ultrasonic probe 01 after being erased, in the present embodiment, the ultraviolet lamp 51 is spaced about 1 cm from the acoustic lens of the ultrasonic probe 01 for sterilization and performs irradiation sterilization for 40 seconds to 60 seconds. In this example, the pitch was selected to be 1 mm and the sterilization time was selected to be 60 seconds.
In the above-mentioned process of erasing the couplant, "the couplant attached to the portion is erased by the relative displacement between the couplant erasing belt 47 and the ultrasonic probe 01", the travelling speed of the couplant erasing belt 47, that is, the rotational speed of the pinch roller 42 is greater than the travelling speed of the contact portion of the couplant erasing belt 47 and the surface of the ultrasonic probe 01 along the surface thereof, and in the whole erasing process, the relative displacement speed between the couplant erasing belt 47 and the ultrasonic probe 01 can be adjusted according to the actual required erasing amount, specifically, can be controlled to (1) make the probe fixing seat travel at a constant speed along the linear guide rail, and the belt driving mechanism 4 drives the couplant erasing belt to change its travelling speed at a preset speed in real time, for example, the belt travelling speed at the place where the erasing amount is large is set faster to ensure the erasing effect, and the belt travelling speed at the place where the erasing amount is smaller is set to save cost; (2) The couplant erasure belt is driven to travel at a constant speed by the driving mechanism 4, and the travel speed of the probe fixing seat 2 along the linear guide rail is driven by the travel driving mechanism to change according to a preset speed in real time, for example, the travel speed of the seat at the place with large erasure amount is set to be slower to ensure the erasure effect, and the travel speed of the seat at the place with less erasure amount is set to be higher to improve the erasure efficiency. In addition, for convenience of control, the couplant erasure belt 47 and the probe fixing seat 2 may both be set to travel at a constant speed, and the speed parameters of both are set to parameters that can ensure the maximum erasure amount. During use, the time to complete the cleaning of one ultrasound probe 01 is typically controlled within the time that the sonographer is ready for the next examination subject to facilitate the operation of the sonographer.
In the whole use process, the couplant erasing belt 47 is tightly wound around the outside of the compressing roller 42 all the time, and in the strokes corresponding to the part of the outer convex smooth surface 242, the whole of the inner concave smooth surface 243 and the part of the outer convex smooth surface 244 in the curved guide surface 240, the coupling action of the cam mechanism is utilized to modulate the displacement between the compressing roller 42 and the probe fixing seat 2 in the vertical direction to a preset interval change curve by utilizing the relative displacement between the compressing roller 42 and the probe fixing seat 2 in the horizontal direction, so that the envelope surface formed by the contact surface of the couplant erasing belt 47 and the ultrasonic probe 01 is forced to completely cover the surface to be erased on the ultrasonic probe 01, thereby ensuring the erasing effect of the couplant.
Since the pinch roller 42 is an elastic roller, the elastic roller may be composed of an elastic ring body sleeved outside the rotating shaft of the elastic roller, or may be composed of a hard ring body sleeved outside the rotating shaft of the elastic roller and an elastic ring body sleeved outside the hard ring body, and during the above-mentioned erasing operation, that is, during the partial travel of the roller 23 in the cam mechanism along the curved guide surface 240 of the parallel cam 24, the minimum distance between the rotating shaft of the pinch roller 42 and the surface of the ultrasonic probe 01 is smaller than the radius of the pinch roller 42, so as to realize the deformation of the elastic roller, and force the couplant erasing belt 47 between the pinch roller 42 and the ultrasonic probe 01 to be pressed into the curved erasing surface surrounding the portion to be erased. In addition, since the compressing roller 42 is an elastic roller, the floating range of the deformation, that is, the elastic deformation, fluctuates within a certain range, but still keeps the couplant erasing belt 47 to be forced to be compressed on the surface to be erased of the ultrasonic probe 01, so that the processing precision requirement on the curved guide surface 240 can be effectively reduced, the requirement on the precision of the curved guide surface 240 can be reduced, and the applicability of the same curved guide surface 240 to different ultrasonic probes with approximately the same shape but changing surface curves within a certain range can be effectively improved. In addition, the matching degree of the surface of the ultrasonic probe 01 can be improved by setting the surface of the pinch roller 42 to a curved shape, for example, the surface of the pinch roller 42 is slightly concave without affecting the driving of the couplant erasing belt 47, so that the matching degree of the surface of the ultrasonic probe 01 can be improved.
In the present embodiment, the probe holder 2 drives the ultrasonic probe 01 to move in a horizontal direction relative to the pinch roller 42 to erase the couplant on the surface of the ultrasonic probe 01, i.e., the horizontal direction constitutes the erasing travelling direction in the present embodiment.
In the cam mechanism of the present embodiment, the linear-motion roller push rod constitutes a driving member, and the parallel cam constitutes a driven member, and is configured such that the push rod moves relative to the base along the length direction of the parallel cam thereof.
