Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning equipment, in particular to an online particle size detection device for ultrasonic cleaning equipment. Background Art

[0002] Ultrasonic cleaning equipment can achieve comprehensive cleaning results on objects, and is particularly ideal for cleaning deep holes, blind holes, and concave and convex grooves, without affecting the material or precision of any object. It is also used for extraction, degassing, mixing, cell pulverization, and nano-decomposition in biochemistry, physics, chemistry, medicine, scientific research, and university experiments.

[0003] However, there are still some problems in actual use: After ultrasonic cleaning equipment has been used for a long time, the cleaning fluid needs to be tested for metal content. The existing method is to extract part of the cleaning fluid by sampling and then use the detection equipment to test it. Ultrasonic cleaning cannot be performed during the test results, which affects the process. The cleaning fluid contains metal particles at different heights, and the test is performed at a single fixed height, resulting in the data not being able to fully reflect the content in the cleaning fluid. Secondly, the detection probe is directly installed inside the equipment, which easily causes the cleaning fluid to fluctuate when the equipment is running, resulting in the real-time online detection equipment taking blurred test pictures, and the content in the cleaning fluid at different heights is uneven, which affects the accuracy of the data. Summary of the Invention

[0014] Compared with the existing technology, this online particle size detection device for ultrasonic cleaning equipment has the following beneficial effects: 1. The invention sets up an online particle detection mechanism. When the driving rod moves downward, the driving gear is inserted into the jack in sequence until its bottom end contacts the bottom of the connecting hole. Then the driving motor is started to drive the driving rod to rotate. At this time, the driving rod drives the gear ring to rotate through the limit bar and the driving gear. The sealing ring drives the stirring bar to slowly stir the cleaning liquid inside the equipment. The particle sensor moves along the sealing trajectory and detects the particle content of the cleaning liquid in real time. The data is then transmitted to the detection body and then displayed on the display, which is conducive to sampling different water layers and improving data diversity and accuracy. Secondly, the flow rate of the cleaning liquid is ensured to rotate at the same speed as the particle sensor to avoid the cleaning liquid flow rate being too fast to affect the data and causing blurred pictures. The metal content of the cleaning liquid is detected in real time to avoid excessive metal content.

[0015] 2. The invention sets up a lifting mechanism, which uses a control motor to drive the control gear to rotate along the same trajectory. Then the driving gear drives the lifting rod through the serrations to slowly insert it into the interior of the connecting hole. At this time, the machine cover drives the other two lifting rods and the driving rod to move downward along the same trajectory, thereby prompting the machine cover to slowly move and close on the top of the ultrasonic cleaning body, which is beneficial to improving the degree of automation of the equipment and facilitating the placement and removal of products inside the equipment. Secondly, it ensures that the machine cover is completely closed inside the body to enhance its sealing.

[0016] 3. The invention sets up a cleaning placement mechanism, which uses an electric push rod to push the rubber block downward. At this time, the rubber block moves downward until the object is squeezed between the placement seat and the opposite side. During this process, the rubber block moves remotely and pulls the drive bar to move along the same trajectory. The top of the drive bar drives the slider to slide relatively on the outside of the fixed axis. Secondly, the return spring is squeezed and contracted under force, which helps to ensure that the object to be ultrasonically cleaned can be stably placed inside the ultrasonic cleaning body, avoiding the stirring of the cleaning liquid inside the equipment when the equipment is running, causing the product to tilt, shake or collide, thereby causing damage to the equipment and blocking the cleaning position, making it impossible to discharge dirt.

[0017] Other advantages, objects and features of the invention will be set forth in part in the description which follows and, in part, will be apparent to those skilled in the art based on an examination of the following or may be learned from practice of the invention.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the online particle detection mechanism 5 includes a gear ring 501, a particle sensor 502, a stirrer 503, a driving gear 504 and a sealing ring 505. The sealing ring 505 is fixedly connected to the inner side of the gear ring 501. There are several stirrers 503 and they are arranged in an annular shape and opposite to each other on the inner side of the sealing ring 505. There are several particle sensors 502 and they are arranged in pairs on the inner side of the sealing ring 505. The driving gear 504 is meshed with the gear ring 501. A conductive groove 9 is provided on the surface of the gear ring 501. The conductive groove 9 is annular and conductive. The inside of the conductive groove 9 is electrically connected to a wire 10, and the wire 10 passes through the ultrasonic cleaning body 1 and is electrically connected to the detection body 2. The online particle detection mechanism 5 also includes a driving motor 506, a driving rod 507 and a transmission bar 508. The driving motor 506 is a driving rod 507 and a transmission bar 508. The driving motor 506 is fixedly connected to the top of the machine cover 4, and the top of the driving rod 507 passes through the machine cover 4 and is fixedly connected to the output end of the driving motor 506. The transmission bar 508 is fixedly connected to the outside of the driving rod 507 in a cross form. Several connecting grooves 11 are opened inside the connecting hole directly below the driving motor 506. Several annular grooves 12 are opened inside the ultrasonic cleaning body 1, and the annular grooves 12 are connected to the connecting grooves 11. The driving gear 504 is respectively located inside the connecting grooves 11. A limiting hole 13 is opened at the axis center of the driving gear 504, and the limiting hole 13 is adapted to the cross-section of the driving rod 507 and the transmission bar 508.

[0023] When the driving rod 507 moves downward, the driving gear 504 is inserted into the socket in sequence until its bottom end contacts the bottom of the connecting hole. Then, the driving motor 506 is started to drive the driving rod 507 to rotate. At this time, the driving rod 507 drives the gear ring 501 to rotate through the limit bar and the driving gear 504. The sealing ring 505 drives the stirring bar to slowly stir the cleaning liquid inside the equipment. The particle sensor 502 moves along the sealing trajectory and detects the particle content of the cleaning liquid in real time. The data is then transmitted to the detection body 2 and displayed on the display 3. This helps to ensure that the flow rate of the cleaning liquid and the particle sensor 502 rotate at the same speed, avoiding the cleaning liquid flow rate being too fast to affect the data and causing blurred images. Secondly, the metal content of the cleaning liquid is detected in real time to avoid excessive metal content. The particle sensor 502 model is "IFD-3 dynamic image particle sensor", which can complete real-time dynamic image capture and accurately detect multi-dimensional indicators such as particle size distribution, number concentration and water contamination.

The output end of the control motor 701 is fixedly connected to the control gear 702. The control motor 701 is fixedly connected to the outside of the ultrasonic cleaning body 1. A groove 14 is provided inward on one side of the ultrasonic cleaning body 1 close to the control gear 702, and the groove 14 is connected to the connecting hole. A rectangular groove 15 is vertically provided on the lifting rod 6 close to the groove 14, and a serration is provided inside the rectangular groove 15. The control gear 702 is respectively engaged and transmitted with the lifting rod 6 through the serration. The top of the lifting rod 6 is respectively fixedly connected with a connecting bar 16, and the connecting bar 16 is symmetrically arranged on the left and right. One end of the connecting bar 16 away from the lifting rod 6 is fixedly connected to the outside of the top of the driving rod 507.

[0025] The control motor 701 drives the control gear 702 to rotate along the same trajectory, and then the driving gear 504 drives the lifting rod 6 through the serrations to slowly insert it into the interior of the connecting hole. At this time, the machine cover 4 drives the other two lifting rods 6 and the driving rod 507 to move downward along the same trajectory, thereby prompting the machine cover 4 to slowly move and close on the top of the ultrasonic cleaning body 1, which is beneficial to improving the degree of automation of the equipment and facilitating the placement and removal of products inside the equipment. Secondly, it ensures that the machine cover 4 is completely closed inside the body to enhance its sealing.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8As shown, the cleaning placement mechanism 8 includes a placement seat 801, a partition net 802, a connecting ring 803, a fixed shaft 804, a slider 805, a reset spring 806, a driving bar 807, an electric push rod 808 and a rubber block 809. The placement seat 801 is fixedly connected to the bottom of the partition net 802, and the connecting ring 803 is fixedly connected to the top of the partition net 802. The fixed shaft 804 is laterally fixedly connected to the inner top of the connecting ring 803, and the slider 805 is symmetrically slidably connected to the outside of the fixed shaft 804.

The return spring 806 is symmetrically arranged on the outside of the fixed shaft 804, and the return spring 806 is respectively located on the opposite sides of the electric push rod 808 and the slider 805. The top of the connecting ring 803 is fixedly connected to the bottom of the machine cover 4.

The rubber block 809 is round and is slidably connected to the inside of the partition net 802.

[0027] The electric push rod 808 pushes the rubber block 809 downward. At this time, the rubber block 809 moves downward until the object is squeezed between the placement seat 801 and the opposite side. During this process, the rubber block 809 moves remotely and pulls the driving bar 807 to move along the same trajectory. The top of the driving bar 807 drives the slider 805 to slide relatively on the outside of the fixed shaft 804. Secondly, the return spring 806 is squeezed and contracted under the force, which is conducive to ensuring that the object to be ultrasonically cleaned can be stably placed inside the ultrasonic cleaning body 1, avoiding the stirring of the cleaning liquid inside the equipment when the equipment is running, causing the product to tilt, shake or collide, thereby causing damage to the equipment and blocking the cleaning position, making it impossible to discharge dirt.

[0028] Working principle: When in use, the object to be ultrasonically cleaned is placed inside the partition net 802, and then the electric push rod 808 is controlled to push the rubber block 809 downward. At this time, the rubber block 809 moves downward until the object is squeezed between the placement seat 801 and the opposite side. During this process, the rubber block 809 moves remotely and pulls the drive bar 807 to move along the same trajectory. The top of the drive bar 807 drives the slider 805 to slide relative to the outside of the fixed shaft 804. Then the return spring 806 is squeezed and contracted by force, and then the control motor 701 is started to drive the control gear 702 to rotate along the same trajectory. Then the drive gear 504 drives the lifting rod 6 downward and slowly inserts it into the interior of the connecting hole through the sawtooth. At this time, the machine cover 4 drives the other two The lifting rod 6 and the driving rod 507 move downward along the same trajectory, thereby causing the machine cover 4 to slowly move and close on the top of the ultrasonic cleaning body 1. When the driving rod 507 moves downward, it is inserted into the driving gear 504 in sequence along the jack until its bottom end contacts the bottom of the connecting hole. Then the driving motor 506 is started to drive the driving rod 507 to rotate. At this time, the driving rod 507 drives the gear ring 501 to rotate through the limit bar and the driving gear 504. The sealing ring 505 drives the stirring bar to slowly stir the cleaning liquid inside the equipment. The particle sensor 502 moves along the sealing trajectory and detects the particulate content of the cleaning liquid in real time. The data is then transmitted to the detection body 2 and displayed on the display 3.
