Description

Technical Field

[0001] This invention belongs to the field of medical device manufacturing technology, and specifically relates to a surface treatment device and method for medical components. Background Technology

[0002] In the field of medical device manufacturing, patient monitors are key devices for clinical monitoring of patients' vital signs. The stability and reliability of their performance are paramount. The monitor casing is not only an important barrier protecting the internal precision electronic components, but also directly affects the device's appearance quality, ease of use, and suitability for medical environments. Monitor casings are typically made of materials such as plastic and metal. During the manufacturing process, the surface quality of the casing is affected by various factors such as mold forming and injection molding processes, which may result in defects such as burrs, flash, and uneven surface roughness. Therefore, polishing the monitor casing is an indispensable and crucial step in the production process. Polishing effectively removes burrs, flash, and other defects from the casing surface, reduces surface roughness, and makes the casing surface smoother and flatter, improving appearance quality. At the same time, polishing also enhances the surface texture of the casing, improves its adhesion to subsequent coating and labeling processes, and ensures that the coating is uniform, firm, and the markings are clear and durable.

[0003] Existing equipment for grinding the casing of monitors has shortcomings in dust collection and removal. The dust generated during grinding cannot be collected and treated in a timely and effective manner, and will still permeate the working environment, posing a threat to the health of operators. It may also pollute the production workshop and affect the normal operation of other equipment. In addition, the casing is prone to shaking or displacement during the grinding process, resulting in uneven grinding and even damage to the casing. To address these issues, we propose a surface treatment device and method for medical components to solve the problems existing in the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a surface treatment device and method for medical components. By cooperating with a dust collection mechanism and a dust collection trough, the dust generated by the grinding mechanism is collected and treated.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface treatment device for medical components includes a grinding box, a box door, a grinding mechanism, a dust collection trough, a clamping mechanism, and a dust collection mechanism. Two sets of boxes door are symmetrically hinged on one side of the grinding box. A grinding mechanism for grinding the surface of medical components is installed on the top of the grinding box. Two sets of dust collection troughs are symmetrically opened on the bottom of the grinding box to collect grinding dust. Two sets of clamping mechanisms for clamping and fixing medical components are symmetrically installed on both sides of the dust collection trough. A dust collection mechanism for use with the dust collection trough is installed below the dust collection trough.

[0007] The dust collection mechanism includes a dust collection shell, a dust collection shell, a filter screen, and a dust collection fan. The dust collection shell is fixedly installed at the bottom of the grinding box, the dust collection shell is installed through one side wall of the dust collection shell, the filter screen is detachably inserted into the inside of the dust collection shell, and the dust collection fan is fixedly installed at the air outlet of the dust collection shell.

[0008] Preferably, the dust collection mechanism further includes a plug slot and a dust discharge box. The plug slot is located at the bottom of one side of the dust collection shell, and the dust discharge box is sealed and plugged into the bottom of the dust collection shell through the plug slot.

[0009] Preferably, the clamping mechanism includes a fixed plate, an electro-hydraulic rod, and a clamping plate. The fixed plate is fixedly installed on the inner bottom of the grinding box, the electro-hydraulic rod is fixedly installed on one side wall of the fixed plate, and one end of the piston rod of the electro-hydraulic rod passes through the fixed plate and is fixedly connected to the clamping plate.

[0010] Preferably, the clamping mechanism further includes two sets of limiting rods, which are installed through the fixed plate and have their outer walls slidably connected to the fixed plate. One end of each set of limiting rods is fixedly installed to one side of the clamping plate.

[0011] Preferably, the grinding mechanism includes two sets of electric push rods, a cross slide, a grinding motor, and a grinding disc. The two sets of electric push rods are symmetrically fixedly installed on the top of the grinding box. One end of the piston rod of each set of electric push rods passes through the grinding box and is fixedly installed on the cross slide. The grinding motor is fixedly installed at the bottom of the sliding end of the cross slide, and the grinding disc is fixedly installed on the outer wall of the output shaft of the grinding motor.

[0012] Preferably, two sets of ventilation fans are installed through the side wall of the grinding box away from the box door, and the air inlets of the ventilation fans are fixedly installed with dustproof nets.

[0013] Preferably, a controller is fixedly installed on one side of the grinding box, and the controller is electrically connected to the electric push rod, the cross slide, the grinding motor, the electric hydraulic rod, the dust extraction fan and the ventilation fan respectively through wires.

[0014] Preferably, an isolation net is fixedly installed inside the dust collection trough, and the top of the isolation net is flush with the inner bottom surface of the grinding box.

[0015] Preferably, the door is provided with an observation window, which is made of explosion-proof transparent material, and the inner side of the observation window is provided with an anti-fog coating. A handle is installed on the outer side of the door.

[0016] A surface treatment method for medical components includes the following steps:

[0017] Step 1: Open the box door, place the medical parts between the two sets of dust collection troughs at the bottom of the grinding box, adjust the position of the parts so that they are in the middle of the two sets of clamping mechanisms, set the extension length of the electric hydraulic rod through the controller, start the electric hydraulic rod, so that the two sets of clamping plates cooperate to stably clamp and fix the medical parts in the grinding box.

[0018] Step 2: Start the electric push rod through the controller. The electric push rod drives the cross slide to descend to the appropriate grinding height. Set the movement path and speed of the cross slide, start the cross slide, and at the same time turn on the grinding motor. The grinding motor drives the grinding disc to rotate at high speed to grind the surface of the medical parts. During the grinding process, the cross slide moves according to the set path to ensure that the surface of the parts is ground evenly.

[0019] Step 3: Check if the filter of the vacuuming mechanism is installed in place and if the dust box is installed in the insertion slot of the dust collection shell to ensure that the vacuuming function is normal. Start the vacuuming fan. Under the suction of the vacuuming fan, the dust generated by the polishing enters the dust collection shell through the dust drop trough. When the dust passes through the filter in the dust collection shell, it is intercepted by the filter. Clean air is discharged through the air outlet of the vacuuming fan. Start the ventilation fan. The ventilation fan introduces the outside air into the polishing box after filtering it through the dust filter, so that air circulation is formed in the polishing box, which helps the vacuuming mechanism to collect dust better and at the same time reduces the temperature inside the polishing box.

[0020] Step 4: After polishing, first turn off the polishing motor and cross slide, then raise and reset the cross slide using the electric push rod, turn off the vacuum fan and ventilation fan, open the box door, control the electric hydraulic rod to retract, loosen the clamping plate, take out the polished medical parts, periodically pull out the dust box from the insertion slot, clean the dust collected in the dust box, disassemble and clean the filter screen to ensure that the vacuuming mechanism continues to maintain good working condition.

[0021] Technical effects and advantages of the present invention: The surface treatment device and method for medical components proposed in this invention have the following advantages compared with the prior art:

[0022] 1. This invention utilizes a dust collection mechanism in conjunction with two sets of dust collection troughs. During the grinding process, the dust collection fan is activated, generating a powerful suction that quickly draws the dust generated during grinding into the dust collection shell through the dust collection troughs. When the dust passes through the filter screen inside the dust collection shell, it is effectively intercepted, while clean air is discharged through the exhaust port of the dust collection fan. This effectively prevents dust from spreading inside the grinding box, ensuring a clean working environment. At the same time, the filter screen is detachably inserted into the dust collection shell, facilitating regular disassembly and cleaning, ensuring that the dust collection mechanism always maintains a good dust collection effect, and extending the service life of the equipment.

[0023] 2. The present invention uses two sets of clamping mechanisms to provide stable and strong clamping force, so that the monitor housing remains stable during the polishing process and does not shake or shift, thus ensuring the precision and quality of polishing. Attached Figure Description

[0039] The electro-hydraulic rod 62 features a low-noise design and a built-in pressure sensor to monitor the clamping force in real time, preventing damage to medical components due to excessive clamping force. The clamping plate 63 is covered with anti-slip rubber pads to increase friction with the components and prevent scratches. The design of the pressure sensor and anti-slip rubber pads enables precise clamping while effectively protecting medical components from damage. The low-noise operation meets the quiet environment requirements of medical facilities. The electro-hydraulic rod 62 can be equipped with Rexroth LFR series electro-hydraulic actuators, with a thrust range of 500-5000N and a stroke accuracy of ±0.1mm, meeting the clamping needs of medical components of different sizes.

[0040] The clamping mechanism 6 also includes two sets of limiting rods 64, which are installed through the fixed plate 61 and the outer wall of the limiting rods 64 is slidably connected to the fixed plate 61. One end of each of the two sets of limiting rods 64 is fixedly installed to one side of the clamping plate 63.

[0041] The limiting rod 64 adopts a linear optical axis, and its surface is hardened, resulting in high hardness and good wear resistance. A linear bearing is installed on the fixing plate 61, which works in conjunction with the limiting rod 64 to make the movement of the clamping plate 63 more stable and smooth. The combination of the hardened linear optical axis and the linear bearing improves the motion accuracy and service life of the clamping mechanism 6.

[0045] Ventilation fan 8 uses an axial flow fan, which features large air volume and low noise. Dust filter 9 is made of metal wire mesh with a rust-proof surface and fine mesh, which can effectively block dust from entering the interior of the grinding box 1. Both ventilation fan 8 and dust filter 9 adopt a quick-release structure for easy regular cleaning and maintenance.

[0050] The door 2 is equipped with an observation window made of explosion-proof transparent material. The inside of the observation window is coated with an anti-fog coating, and a handle is installed on the outside of the door 2.

[0051] The observation window uses a double-layer tempered glass laminated structure, which has good explosion-proof performance and light transmission; the anti-fog coating uses nanotechnology, which can effectively prevent the glass from fogging due to the temperature difference between the inside and outside of the grinding box 1; the handle is ergonomically designed with anti-slip texture on the surface, making it easy for operators to open and close the box door.

[0052] A surface treatment method for medical components includes the following steps:

[0053] Step 1: Open the box door 2, place the medical parts in the middle of the two sets of dust collection grooves 4 at the bottom of the grinding box 1, adjust the position of the parts so that they are in the middle of the two sets of clamping mechanisms 6, set the extension length of the electric hydraulic rod 62 through the controller, start the electric hydraulic rod 62, so that the two sets of clamping plates 63 cooperate to stably clamp and fix the medical parts in the grinding box 1.

[0054] Step 2: Start the electric push rod 31 through the controller. The electric push rod 31 drives the cross slide 32 to descend to the appropriate grinding height. Set the moving path and speed of the cross slide 32, start the cross slide 32, and at the same time turn on the grinding motor 33. The grinding motor 33 drives the grinding disc 34 to rotate at high speed to grind the surface of the medical parts. During the grinding process, the cross slide 32 moves according to the set path to ensure that the surface of the parts is ground evenly.

[0055] Step 3: Check whether the filter 73 of the vacuuming mechanism 7 is installed in place and whether the dust box 76 is installed in the insertion slot 75 of the dust collection shell 71. Ensure that the vacuuming function is normal. Start the vacuuming fan 74. Under the suction of the vacuuming fan 74, the dust generated by the polishing enters the dust collection shell 71 through the dust drop trough 4. When the dust passes through the filter 73 in the dust collection shell 72, it is intercepted by the filter 73. Clean air is discharged through the air outlet of the vacuuming fan 74. Start the ventilation fan 8. The ventilation fan 8 introduces the outside air into the polishing box 1 after filtering through the dust filter 9, so that airflow is formed in the polishing box 1, which helps the vacuuming mechanism 7 to collect dust better and at the same time reduces the temperature inside the polishing box 1.

[0056] Step 4: After polishing, first turn off the polishing motor 33 and the cross slide 32, then raise and reset the cross slide 32 using the electric push rod 31, turn off the vacuum fan 74 and the ventilation fan 8, open the box door 2, control the electric hydraulic rod 62 to retract, loosen the clamp 63, take out the polished medical parts, periodically pull out the dust box 76 from the insertion slot 75, clean the dust collected in the dust box 76, disassemble and clean the filter screen 73, and ensure that the vacuuming mechanism 7 continues to maintain a good working condition.
