Description

Technical Field

[0001] This invention belongs to the field of dust removal equipment technology, specifically relating to a batch dust removal mechanism for instruments and meters. Background Technology

[0002] Instruments and meters are devices or equipment used to detect, measure, observe, and calculate various physical quantities, material compositions, and physical properties. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc., all fall under the category of instruments and meters. Instruments and meters, especially precision electronic instruments, sensors, and various industrial meters, are prone to accumulating dust, oil, and other impurities on their outer surfaces during use and storage. These impurities not only affect the cleanliness and appearance of the instruments but may also penetrate into instrument gaps, affecting the clarity of the display window and even potentially damaging internal precision components, thus shortening their service life. Therefore, regularly cleaning and dusting the surfaces of batches of instruments and meters is an important part of production maintenance.

[0003] Currently, automated cleaning equipment uses rigid clamps in conjunction with roller brushes for cleaning. Although this improves efficiency, rigid clamps are prone to causing indentations or scratches on the instrument surface, which can easily damage the instruments and result in defective products. In addition, rigid clamps have poor adaptability to instruments of different sizes and shapes, resulting in low efficiency and safety. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a batch dust removal mechanism for instruments and meters.

[0005] The technical solution adopted to solve the above technical problems is: a batch dust removal mechanism for instruments and meters, including a concave frame, a concave conveyor belt rotatably connected to the inner side of the concave frame, several roller brushes fixedly connected to both sides of the top of the concave frame, a support frame fixedly connected to both sides of the middle part of the concave frame, a mounting frame rotatably connected between the tops of two support frames, a roller conveyor frame fixedly connected to the upper and lower ends of the inner side of two mounting frames, and a flexible clamping mechanism provided between the mounting frame and the roller conveyor frame.

[0006] Furthermore, the soft clamping mechanism includes several stretch bandages, which are respectively located between the gaps of each roller in the mounting frame. The inner sides of each stretch bandage are rotatably connected to a first roller, and the first rollers are grouped in pairs. A T-shaped column is fixedly connected between the two first rollers in the same group.

[0007] With the above technical solution, when it is necessary to clamp and clean the instrument, these bandages with a certain width and flexibility can extend from the roller gap and adaptively wrap around the side and contour of the instrument, providing a large area and uniform flexible contact and pressure, so as to effectively fix instruments of different sizes and shapes, and avoid surface scratches or indentations that may be caused by traditional rigid clamps.

[0008] Furthermore, hydraulic telescopic rods are fixedly connected to the middle of both sides of the mounting frame, and a pull plate is fixedly connected to the telescopic end of the hydraulic telescopic rod. The pull plate is located on the side away from the roller conveyor frame, and both ends of the pull plate are fixedly connected to two T-shaped columns respectively.

[0009] Through the above technical solution, the extension and retraction operation of the hydraulic telescopic rod is achieved by automatically tightening and loosening the pull plate and the two ends of the T-shaped column strap by moving away from and closer to each other, thus realizing the clamping and release operation of instruments and meters.

[0010] Furthermore, several H-shaped frames are fixedly connected to both sides of the mounting frame, and the several H-shaped frames correspond to the T-shaped columns. The H-shaped frames are located between the T-shaped columns and the roller conveyor frame. Slide grooves are provided on both sides of the H-shaped frames, and connecting columns are slidably connected to the inner side of the slide grooves. Second rollers are fixedly connected to both ends of the connecting columns, and the second rollers are rotatably fitted with the stretching bandage.

[0011] With the above technical solution, the two connecting columns are located on the upper and lower sides of the H-shaped frame 14 respectively, forming a symmetrical structure. In conjunction with the tensioning mechanism, the tension of the upper and lower parts of the same tensioning bandage 16 is the same, which can provide a stable and uniform clamping force for the instruments and meters, avoid the instruments and meters from falling due to subsequent flipping operations, and improve the safety of the device.

[0012] Furthermore, a spring is provided through the middle of the H-shaped frame, and push plates are fixedly connected to the upper and lower ends of the spring, respectively. The two ends of the push plates are slidably connected to the slide grooves, and the surface of the push plates is in contact with and fits against the connecting column.

[0013] Through the above technical solution, the upper and lower second rollers are kept far apart under the push of the spring, so that the middle of the bandage is kept with sufficient gap, which facilitates the entry and exit of instruments.

[0014] Furthermore, the support frame is rotatably connected to a first grooved wheel and a second grooved wheel at its upper and lower ends, respectively. A transmission belt is connected between the first grooved wheel and the second grooved wheel through friction transmission. The middle part of the first grooved wheel is rotatably connected through the support frame and the concave frame. A motor is installed at the through end of the first grooved wheel. The power output end of the motor is fixedly connected to the through end of the first grooved wheel. The middle part of the second grooved wheel is rotatably connected through the support frame. The through end of the second grooved wheel is fixedly connected to the mounting frame.

[0015] Through the above technical solution, a motor provides power to drive the first active grooved wheel to rotate, and the power is transmitted to the driven second grooved wheel via a transmission belt. The output end of the second grooved wheel is directly fixedly connected to the mounting frame, thereby accurately and stably transmitting the rotational motion of the motor to the mounting frame and its integrated flexible clamping mechanism and roller conveyor. The motor then drives the mounting frame to rotate, enabling the internal instruments to be flipped. Therefore, this mechanism can clean both sides of the instruments, achieving comprehensive cleaning.

[0016] The beneficial effects of this invention are as follows: 1. This invention utilizes the synergistic effect of a flexible clamping mechanism and a driving mechanism. This mechanism integrates flexible adaptive clamping, double-sided flipping cleaning, and continuous conveying, significantly improving the batch dust removal efficiency and cleaning quality of instruments of different shapes and sizes, while eliminating the risk of surface scratches. It has good practicality and safety.

[0017] 2. When the instrument is transported to the mounting area, the hydraulic telescopic rod moves, and the pull plate and T-shaped column drive the two ends of each set of tension bandages to move outward, so that the bandages extend out of the gap between the rollers and adaptively wrap and gently clamp the instrument, effectively avoiding damage caused by rigid clamping.

[0018] 3. This invention uses a motor to drive the entire mounting frame and the clamped instrument to rotate via a grooved pulley and belt drive, so that both sides of the instrument can be thoroughly cleaned by the roller brush. The grooved pulley and belt drive method ensures smooth operation, low noise, and facilitates maintenance by staff. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figures 1 to 3 As shown, this embodiment of a batch dust removal mechanism for instruments and meters includes a concave frame 1, with a concave conveyor belt 2 rotatably connected to the inner side of the concave frame 1. The concave structure design allows a flexible clamping mechanism to be set in the central recess. Several roller brushes 3 are fixedly connected to both sides of the top of the concave frame 1. Each roller brush 3 on both sides performs cleaning and dust removal operations on the instruments and meters. Support frames 4 are fixedly connected to both sides of the middle of the concave frame 1. Mounting frames 9 are rotatably connected between the tops of the two support frames 4. Roller conveyor frames 10 are fixedly connected to the upper and lower ends of the inner sides of the two mounting frames 9 for receiving and transporting instruments and meters. A flexible clamping mechanism is provided between the mounting frames 9 and the roller conveyor frames 10. This mechanism integrates flexible adaptive clamping, double-sided flip cleaning, and continuous conveying, significantly improving the batch dust removal efficiency and cleaning quality of instruments and meters of different shapes and sizes, while eliminating the risk of surface scratches. It has good practicality and safety.

[0023] The flexible clamping mechanism includes several stretch bandages 16, which can be freely stretched and tightened. The stretch bandages 16 are located between the roller gaps of the mounting frame 9. The stretch bandages 16 with a certain width and flexibility can extend out from the roller gaps. The first rollers 15 are rotatably connected to the two sides inside the stretch bandages 16. By driving the first rollers 15 away from each other, the middle of the stretch bandages 16 is tightened and stretched, while adaptively wrapping the sides and contours of the instrument, providing a large area of ​​uniform flexible contact and pressure. This can effectively fix instruments of different sizes and shapes, and avoid surface scratches or indentations that may be caused by traditional rigid clamps.

[0024] Several first reels 15 are grouped in pairs. T-shaped posts 13 are fixedly connected between two first reels 15 in the same group. Hydraulic telescopic rods 11 are fixedly connected to the middle of both sides of the mounting frame 9. Pull plates 12 are fixedly connected to the telescopic ends of the hydraulic telescopic rods 11. The pull plates 12 are located on the side away from the roller conveyor frame 10. The two ends of the pull plates 12 are fixedly connected to two T-shaped posts 13 respectively. The hydraulic telescopic rods 11 drive the T-shaped posts 13 to move, thereby moving the two ends of the bandage away from each other and automatically tightening it to achieve the clamping operation.

[0025] Several H-shaped frames 14 are fixedly connected to both sides of the mounting frame 9. These H-shaped frames 14 correspond to T-shaped columns 13 and are located between the T-shaped columns 13 and the roller conveyor frame 10. Slide grooves 17 are provided on both sides of each H-shaped frame 14, and connecting columns 20 are slidably connected to the inner side of each slide groove 17. Two connecting columns are located on the upper and lower sides of the H-shaped frame 14, forming a symmetrical structure. This, combined with the tensioning mechanism, further enhances the tension. Second rollers 18 are fixedly connected to both ends of each connecting column 20. The second rollers 18 and... The stretch bandage 16 rotates and fits together. A spring 21 is installed through the middle of the H-shaped frame 14, which provides restoring force. Push plates 19 are fixedly connected to the upper and lower ends of the spring 21, and the spring 21 and push plates 19 maintain a certain distance. The two ends of the push plates 19 are slidably connected to the slide grooves 17. The surface of the push plates 19 is in contact with the connecting columns 20. Under the action of the spring 21, the push plates 19 push the connecting columns 20 away from each other, so that the middle of the stretch bandage 16 maintains a sufficient gap, which facilitates the entry and exit of instruments.

[0026] The support frame 4 has a first grooved wheel 6 and a second grooved wheel 8 rotatably connected to its upper and lower ends, respectively. A transmission belt 5 is connected between the first grooved wheel 6 and the second grooved wheel 8 through friction transmission. The transmission method of grooved wheel and belt is smooth and low noise, and also facilitates maintenance by the staff. The middle part of the first grooved wheel 6 is rotatably connected to the support frame 4 and the concave frame 1. A motor 7 is installed at the through end of the first grooved wheel 6. The power output end of the motor 7 is fixedly connected to the through end of the first grooved wheel 6. The motor 7 drives the first grooved wheel 6 to rotate. The middle part of the second grooved wheel 8 is rotatably connected to the support frame 4. The through end of the second grooved wheel 8 is fixedly connected to the mounting frame 9. The second grooved wheel 8 and the mounting frame 9 are rigidly connected. Through this transmission structure, the motor 7 ultimately drives the mounting frame 9 to rotate, so as to perform the flipping operation of the instrument.

[0027] The working principle of this embodiment is as follows: First, the staff places the instruments to be cleaned onto one end of the concave conveyor belt 2. During the conveying process of the concave conveyor belt 2, the two rollers 3 on one side of the concave frame brush wheel 1 perform preliminary cleaning on the surface of the instruments.

[0028] During this process, the connecting column 20 and the second roller 18 in the sliding grooves 17 on both sides of the H-shaped frame 14 will slide outward under the elastic force applied by the spring 21 through the push plate 19, ensuring that the middle section of the tension bandage 16 remains relaxed in the non-clamped state, leaving space for the instrument to enter.

[0029] Once the instrument reaches the middle of the two roller conveyor frames 10, the piston rod of the hydraulic telescopic rod 11 extends, pushing the pull plate 12 to move away from the roller conveyor frames 10. The pull plate 12 drives the T-shaped columns 13, which are fixedly connected to its two ends, to move outward synchronously. The outward movement of the T-shaped columns 13 causes the two sets of first rollers 15 connected to them to move away from each other, thereby pulling the wound or slack tension bandage 16 out to both sides and tightening it. The tightened tension bandage 16 protrudes from the roller gap of the mounting frame 9, adaptively conforming to and wrapping the side contour of the instrument, forming a large-area, flexible clamping force, thereby reliably fixing the instrument without damaging its surface.

[0030] At this time, the motor 7 is started. Driven by the transmission belt 5, the first grooved pulley 6, and the second grooved pulley 8, the entire mounting frame 9, together with the roller conveyor frame 10 on it, the clamped instrument, and the entire flexible clamping mechanism, begins to rotate around its axis, thereby realizing the flipping of the instrument.

[0031] Subsequently, the piston rod of the hydraulic telescopic rod 11 retracts, releasing the instrument. With the cooperation of the roller conveyor frame 10 and the concave conveyor belt 2, the two roller brushes 3 on the other side clean the other side of the flipped instrument, completing the double-sided dust removal operation.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
