Description

Technical Field

[0001] This utility model relates to the field of medical device cleaning technology, and in particular to a push-blade cleaning device. Background Technology

[0002] In automated medical device testing, blood smear preparation is a routine and crucial pretreatment step. During the preparation of a blood smear, the blade of the pusher directly contacts the glass slide and pushes the blood sample. Inevitably, blood stains and other contaminants will adhere to the pusher's surface during this process. Therefore, after each blood smear preparation, it is necessary to clean and air-dry it to ensure its cleanliness for subsequent use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a pusher cleaning device that can automatically complete the cleaning and drying process of the pusher, with a high degree of automation.

[0004] The technical solution of this utility model is:

[0005] A push-blade cleaning device includes a base plate and a vertical plate fixed to the base plate, characterized in that a push-blade lifting mechanism is installed on the vertical plate, and its drive output end is connected to a support platform for clamping the push-blade.

[0006] On the base plate, and below the support platform, a cleaning module and a drying module are slidably connected in sequence along the X direction;

[0007] The cleaning module includes a cleaning tank with an open top surface and an ultrasonic transducer disposed on the cleaning tank.

[0008] The air-drying module includes a high-speed fan and an air-drying duct connected to the air outlet of the high-speed fan. The air-drying duct is provided with an upper air-drying outlet and a lower air-drying outlet at its end, which are arranged opposite to each other at intervals along the X direction.

[0009] Furthermore, a slide rail is provided along the X direction on the base plate, and a mounting plate is slidably connected on the slide rail. The cleaning module and the drying module are fixedly connected to the mounting plate.

[0010] A rotary motor and a timing belt assembly are mounted on the base plate. The drive output end of the rotary motor is connected to the timing belt assembly. The timing belt in the timing belt assembly is fixedly or detachably connected to the mounting plate to drive the mounting plate to move along the X direction.

[0011] Furthermore, the pusher blade on the support platform remains tilted relative to the base plate.

[0012] Furthermore, a partition plate is provided along the Z direction inside the cleaning tank, which divides the cleaning tank into a cleaning chamber and an overflow chamber, and the top surface of the partition plate is lower than the top surface of the cleaning chamber and the overflow chamber.

[0013] Furthermore, an inlet is provided at the upper end of the cleaning chamber, below the top surface of the partition plate. The inlet is connected to the storage tank via a delivery pipe, and a power pump P2 is installed on the delivery pipe. A detection port is provided at the lower end of the cleaning chamber, and a liquid level sensor is installed on the mounting plate. The detection port is connected to the detection end of the liquid level sensor.

[0014] Both the cleaning chamber and the overflow chamber have drain ports on their bottom surfaces. Both drain ports are connected to the waste liquid tank through drain pipes. A power pump P1 is installed on the drain pipe between the cleaning chamber and the waste liquid tank.

[0015] Furthermore, the drying duct includes:

[0016] The main air outlet duct is connected to the air outlet of the high-speed fan;

[0017] The first and second air drying ducts branch off from the outlet end of the high-speed fan. The first and second air drying ducts are arranged in an approximately "U" shape relative to each other. The end of the first air drying duct forms an upper air drying outlet, and the end of the second air drying duct forms a lower air drying outlet. The upper air drying outlet is adjacent to one side of the cleaning chamber. The first and second air drying ducts are fixed to the mounting plate.

[0018] Furthermore, the sides of the upper and lower air-drying inlets that face each other are sloping, forming a V-shaped opening overall.

[0019] Furthermore, the height of the air outlet of the upper dry vent is slightly higher than the height of the air outlet of the lower dry vent.

[0020] Furthermore, on both sides of the first and second air drying ducts along the Y direction, there is a baffle plate to prevent the spread of wind.

[0021] Furthermore, the mounting plate has openings corresponding to the upper and lower air vents; the air outlet duct is installed on the bottom surface of the mounting plate, below its openings, and communicates with the upper and lower air vents.

[0022] The beneficial technical effects of this utility model are:

[0023] 1. This utility model achieves automated cleaning and drying of push blades through the coordinated action of the push blade lifting mechanism, the cleaning module, and the air drying module, thereby improving the cleaning efficiency of push blades.

[0024] 2. This utility model uses an inclined pusher blade for the cleaning and drying processes. On the one hand, this helps the cleaning fluid to flow more smoothly on the surface of the pusher blade, ensuring the effectiveness of ultrasonic cleaning. On the other hand, the upper and lower air-drying inlets of this utility model are constructed with a V-shaped double-sided air-blowing channel structure, which, together with the inclined pusher blade, greatly increases the effective drying area, shortens the drying time, and improves the drying efficiency.

[0025] 3. The liquid level sensor of the cleaning module of this utility model monitors the liquid level in the cleaning chamber in real time, realizing automatic stop of liquid addition. In addition, the overflow chamber design can effectively prevent the cleaning fluid from leaking into the equipment when the liquid level sensor fails unexpectedly, thus improving the long-term stability of the equipment.

[0026] 4. Compared with existing technologies that use lint-free cloths for wiping or complex air compressor systems, this utility model uses a high-speed fan to directly generate a strong airflow for drying, making the overall device structure simpler and effectively reducing manufacturing costs.

Detailed Implementation

[0037] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0038] like Figures 1-8 This utility model provides a pusher cleaning device for automatically cleaning and drying push rods.

[0039] The cleaning device of this utility model includes a horizontally arranged base plate 100, and a vertical plate 101 is fixedly connected to the upper surface of the base plate 100 along the Z direction, the length of the vertical plate 101 extending along the Z direction. A pusher lifting mechanism 200 is installed on the vertical plate 101.

[0040] The pusher lifting mechanism 200 includes a lead screw motor 201, a lifting slider 202, and a lifting plate 203. A first connecting plate 102 is fixedly connected to one side of the top surface of the upright plate 101. The first connecting plate 102 is parallel to the base plate 100 and has a mounting hole in which a bearing sleeve 105 is installed. A second connecting plate 103 is fixedly fixed vertically downward on the side of the first connecting plate 102 away from the upright plate 101. The second connecting plate 103 is perpendicular to the base plate 100. The lifting slider 202 is fixedly connected to the second connecting plate 103. A lifting rail is provided along the Z-direction on the lifting plate 203, and the lifting rail is slidably connected to the lifting slider 202.

[0041] A top plate 104 is fixedly connected to the top surface of the lifting plate 203, and the top plate 104 is set parallel to the bottom plate 100. The fixed end of the lead screw motor 201 is connected to the top plate 104, and its lead screw 2011 passes through the bearing sleeve 105 on the first connecting plate 102 downward along the Z direction and is located above the bottom plate 100.

[0042] Start the lead screw motor 201, and its lead screw 2011 rotates and rises and falls within the bearing sleeve 105, thereby driving the lifting plate 203, the mounting plate 104, and the lead screw motor 201 on the mounting plate 104 to rise and fall synchronously along the Z direction.

[0043] Preferably, to increase the stability of the upright plate 101, a horizontal baffle 106 is also fixedly connected to the lower end of the upright plate 101.

[0044] A support platform 300 for placing the pusher 000 is fixedly connected to the bottom end of the lifting plate 203. The support platform 300 includes a support frame 301, a pressure plate seat 302, an angle adjusting rod 303, and a limiting torsion spring 304. Figure 4 As shown, the support frame 301 comprises a transverse frame body and two support arms 3011 extending outward from both ends and then folding vertically downward. The frame body is detachably connected to the bottom end of the lifting plate 203 by fasteners (such as bolts), and a pressure plate seat 302 is connected between the two support arms 3011 for clamping the push knife 000.

[0045] The tablet press 302 includes a base 3021 and a tablet press 3022. The base 3021 is generally wedge-shaped, with a rectangular left side and a beveled right side. The upper surface of the beveled right side is recessed to form a tablet chamber 3023 for holding the pusher 000. The top and front of the tablet chamber 3023 are open to facilitate the insertion of the pusher. On the rear side inside the tablet chamber, an upper stepped surface 3024 is provided, with mounting holes. The tablet press 3022 is a wedge-shaped piece that matches the shape and size of the tablet chamber 3023, and it also has mounting holes corresponding to the mounting holes on the tablet chamber. The bottom surface of the rear side of the tablet press 3022 protrudes downwards to form a lower stepped surface. During assembly, the lower stepped surface of the tablet 3022 abuts against the upper stepped surface 3024 of the tablet chamber 3023, thereby covering the tablet chamber with the tablet 3022. At this time, a slit is formed between the bottom surface of the front end of the tablet 3022 and the bottom surface of the front end of the tablet chamber. The gap of this slit is equivalent to the thickness of the pusher 000. After placing the pusher in the slit, bolts are passed through the mounting holes on the tablet and the tablet chamber and locked, so that the pusher 000 can be detachably and firmly clamped on the tablet holder 302.

[0046] To ensure the pusher fixed to the tablet press 302 is tilted, the front ends of the two support arms 3011 on the support frame 301 are rotatably connected to both sides of the base 3021 via pins 305. Furthermore, to maintain a specific tilt angle for the tablet press 302, an adjustment rod 303 is fixedly connected between the two support arms 3011, behind the pins 305. A limiting torsion spring 304 is also fitted onto each pin 305. One end of each limiting torsion spring 304 acts on the front side of the adjustment rod 303, and the other end acts on the rear side of the adjustment rod 303 (or directly on the base 3021), thereby applying a torque that tilts the tablet press downwards and backwards. Thus, the tablet press 302 and the pusher on it are held in a tilted state relative to the base plate 100, with an included tilt angle of less than 90 degrees. The significance of this design is that when the pusher is ultrasonically cleaned in the cleaning tank described later, the tilt angle helps the cleaning fluid to flow more smoothly across the pusher surface, avoiding the retention of air bubbles that may occur when it is laid flat, thereby improving the cleaning effect. At the same time, the tilted posture of the pusher also allows the airflow in the following air duct to make more full contact with both sides of the pusher, achieving efficient double-sided drying.

[0047] A slide rail 600 is mounted on the base plate 100, below the pusher 000, along the X direction. A mounting plate 107 is slidably connected to the slide rail 600. To drive the mounting plate 107, the fixed end of the rotary motor 601 is fixed to the bottom surface of the base plate 100. Its drive output end passes through the base plate 100 along the Z direction and connects to a synchronous belt assembly. This synchronous belt assembly is existing technology and includes two synchronous pulleys 602 arranged parallel to one side of the slide rail 600 along the X direction and a synchronous belt 603 tensioned and sleeved on the two synchronous pulleys. One of the synchronous pulleys acts as the driving pulley and is directly connected to the drive output end of the rotary motor 601. The other synchronous pulley is mounted on the base plate, and one end of the synchronous belt 603 is fixed to the mounting plate 107.

[0048] When the rotary motor 601 rotates, it drives the mounting plate 107 to slide along the slide rail 600 via the synchronous belt assembly.

[0049] On the mounting plate 107, a cleaning module and a drying module are arranged sequentially along the X direction.

[0050] The cleaning module includes a cleaning tank 401 with an open top, an ultrasonic transducer 403, and a liquid level sensor 404.

[0051] The bottom surface of the cleaning tank 401 is fixed to the mounting plate 107. A baffle plate 402 is installed inside the cleaning tank 401 along the Z-direction, dividing the cleaning tank 401 into a cleaning chamber 4011 and an overflow chamber 4012. The top surface of the baffle plate 402 is lower than the top surfaces of the cleaning chamber 4011 and the overflow chamber 4012, thus forming a connecting channel at the top of the cleaning chamber and the overflow chamber. The cleaning chamber 4011 is the cleaning area for the pusher blade, and the overflow chamber 4012 prevents the liquid in the cleaning tank 401 from overflowing entirely. Specifically:

[0052] An inlet 4013 is provided on the upper part of the cleaning chamber 4011 and below the top surface of the partition plate 402. The inlet 4013 is connected to the storage tank 405 through a conveying pipe. A power pump P2407 for pumping the cleaning liquid in the storage tank into the cleaning chamber 4011 is also provided on the conveying pipe between the inlet 4013 and the storage tank 405.

[0053] Both the cleaning chamber 4011 and the overflow chamber 4012 have drain ports at their bottoms. These drain ports are connected to the waste liquid tank 406 via drain pipes. A discharge power pump P1408 is installed on the drain pipe between the drain port on the cleaning chamber 4011 and the waste liquid tank 406. This pump actively pumps the cleaning fluid from the cleaning chamber 4011 into the waste liquid tank 406 after the cleaning process is completed. If, due to unforeseen circumstances (such as a level sensor malfunction as described below), there is too much cleaning fluid in the cleaning chamber 4011, exceeding the height of the baffle plate 402, the excess cleaning fluid will overflow over the top of the baffle plate 402 into the overflow chamber 4012, and then flow into the waste liquid tank 406 through the drain port of the overflow chamber 4012.

[0054] To achieve precise control of the liquid addition, a detection port 4015 is provided on the lower end of the cleaning chamber 4011. A transition plate is fixed on the mounting plate 107, and a liquid level sensor 404 is installed on the transition plate. The detection end of the liquid level sensor 404 is connected to the detection port 4015, thereby enabling synchronous detection of the liquid level height inside the cleaning chamber 4011.

[0055] When the control system starts the power pump P2 to add liquid to the cleaning chamber 4011, once the liquid level sensor 404 detects that the liquid level has reached the preset height, it will send a sensing signal to the control system, and the power pump P2 will stop adding liquid to the cleaning chamber 4011. The liquid level sensor 404 is existing technology; the liquid level sensor 404 of this invention is a capacitive liquid level sensor.

[0056] The ultrasonic transducer 403 is fixed on the outer wall of the cleaning chamber 4011. When the cleaning chamber is filled with cleaning fluid and the pusher is immersed in the cleaning chamber, the ultrasonic transducer 403 is activated. It can convert electrical energy into high-frequency mechanical vibration and transmit it to the cleaning fluid through the wall of the cleaning chamber, causing countless tiny vacuum bubbles to be generated. When these bubbles burst, they generate a powerful impact force, which can effectively break up and peel off the blood stains attached to the surface of the pusher, achieving efficient cleaning.

[0057] The air-drying module is used to dry the cleaned pusher blades. It includes a high-speed fan 500 that provides the high-speed airflow required for drying, an air-drying duct 501 for guiding and distributing the airflow, and an exhaust duct 502 for collecting exhaust gas.

[0058] The air drying duct 501 includes a main air outlet duct 5011, whose inlet end is connected to the air outlet of the high-speed fan 500. The outlet end of the main air outlet duct 5011 is divided into two branches: a first air drying duct 5012 and a second air drying duct 5013. The first and second air drying ducts are fixed on the mounting plate 107. To achieve synchronous and efficient drying of both sides of the blade, the first air drying duct 5012 and the second air drying duct 5013 are arranged in an approximately "U" shape. The end of the first air drying duct 5012 furthest from the main air outlet duct forms an upper air drying outlet 5012a, and the end of the second air drying duct 5013 furthest from the main air outlet duct forms a lower air drying outlet 5013a. The upper air drying outlet 5012a and the lower air drying outlet 5013a are arranged opposite each other along the X direction, and the space between them is the blade drying station. Both the upper air drying inlet 5012a and the lower air drying inlet 5013a are located behind the cleaning chamber 4011 along the X direction. In this utility model, the upper air drying inlet 5012a is arranged adjacent to the cleaning chamber 4011.

[0059] To accommodate the inclined pusher blade, the facing surfaces of the upper air drying inlet 5012a and the lower air drying inlet 5013a are designed as inclined surfaces, forming a V-shaped opening. This facilitates the smooth introduction of the pusher blade 000 into the air drying station during its descent, avoiding collisions.

[0060] Furthermore, the outlet height of the upper air drying port 5012a is slightly higher than that of the lower air drying port 5013a. When the inclined pusher blade descends to the pusher blade drying station, the outlet of the upper air drying port 5012a is located diagonally above the front of the pusher blade, while the outlet of the lower air drying port 5013a is located diagonally below the back of the pusher blade. This allows the high-speed airflow to simultaneously and directly impact the upper and lower surfaces of the pusher blade, greatly improving the drying efficiency and effect.

[0061] To improve wind energy utilization and ensure safe exhaust gas discharge, a wind deflector 503 is provided on both sides of the upper air outlet 5012a and the lower air outlet 5013a along the Y direction on the first air drying duct 5012 and the second air drying duct 5013 to prevent wind spread.

[0062] Furthermore, an opening is provided on the mounting plate 107 at the position corresponding to the pusher drying station. An air outlet duct 502 is installed below the mounting plate 107, and the inlet end of the air outlet duct 502 is connected to the opening of the mounting plate 107 and the pusher drying station, so as to guide the moisture and working exhaust gas blown over the pusher to the outside of the equipment and keep the inside of the equipment clean.

[0063] Preferably, to precisely control the upward and downward stroke of the pusher 000, two photoelectric sensors 204 are installed from top to bottom along the Z-direction on one side of the second connecting plate 103. On the same side of the lifting plate 203 corresponding to the photoelectric sensors 204, two lifting limit plates 205 are installed at intervals from top to bottom along the Z-direction. When the lifting plate 203 descends, the upper lifting limit plate 205 descends to the photoelectric sensor 204 at the upper end of the second connecting plate 103, and the lifting plate 203 stops. At this time, the pusher is positioned in the cleaning chamber or the pusher drying station. When the lifting plate 203 rises, the lower lifting limit plate 205 rises to the photoelectric sensor 204 at the lower end of the second connecting plate 103, and the lifting plate 203 stops, and the pusher also rises and resets.

[0064] Preferably, in order to accurately control the travel of the cleaning module and the drying module along the X direction so that the cleaning chamber and the pusher drying station can accurately move to the position below the pusher each time, a photoelectric sensor 204 is provided on the bottom surface of the base plate 100 at each end corresponding to the position of the slide rail 600; a translation limit plate 108 is installed on the bottom surface of the mounting plate 107. When the translation limit plate 108 moves to any photoelectric sensor 204, the mounting plate 107 stops, and the cleaning chamber or the pusher drying station is exactly located below the pusher.

[0065] The operation process of this utility model is as follows:

[0066] The cleaning pusher is clamped on the support platform. The power pump P2 pumps the cleaning fluid from the storage tank 405 into the cleaning chamber 4011. When the cleaning fluid in the cleaning chamber reaches the preset height, the liquid level sensor 404 sends a sensing signal. The rotary motor 601 drives the synchronous belt assembly to move the cleaning chamber below the pusher 000. The pusher lifting mechanism drives the pusher to immerse itself in the cleaning fluid in the cleaning chamber. Then, the ultrasonic transducer 403 is activated to clean the surface of the pusher. After cleaning is completed, the pusher rises with the pusher lifting mechanism. The pusher drying station moves to below the pusher under the drive of the rotary motor 601 and the synchronous belt assembly. The pusher descends to between the upper and lower drying ports (i.e., the pusher drying station). The high-speed fan starts to dry the water stains on the pusher surface. At the same time, the power pump P1 starts to empty the cleaning fluid in the cleaning chamber.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
