Description

Technical Field

[0001] This invention relates to the field of weighing equipment technology, and in particular to an automatic ball dispensing and weighing device. Background Technology

[0002] Small spheres are used as auxiliary materials in 3C electroplating, and their formulations vary, requiring precise mixing and weighing of various spherical materials of different sizes or materials according to preset ratios. To achieve automatic proportioning of such multi-component materials, existing equipment typically uses multiple independent feeding mechanisms. A sliding mechanism moves the weighing container sequentially beneath each feeding mechanism, and a weighing sensor provides real-time weight feedback to control the amount of each component added. While this type of equipment improves batching efficiency to some extent, its weighing accuracy is significantly affected by the material feeding method.

[0003] In existing technologies, when material falls from the feeding mechanism into the weighing container, it typically uses free fall, dropping vertically from a certain height directly onto the bottom of the measuring cylinder or the surface of existing materials inside. During this process, the material's gravitational potential energy is rapidly converted into kinetic energy, resulting in a violent collision with the bottom of the container or the materials inside, generating a significant instantaneous impact force. This impact force is transmitted to the weighing sensor through the measuring cylinder, causing the sensor reading to fluctuate wildly at the moment of feeding, making it unable to stably reflect the actual weight of the added material. This severely affects weighing efficiency and proportioning accuracy, making it difficult to meet the production requirements of high-precision automatic proportioning. Summary of the Invention

[0004] The purpose of this application is to address the problems existing in the background technology by proposing an automatic ball-sorting and weighing device that eliminates the interference of dynamic impact on weighing data during the material falling process.

[0015] Optionally, the feeding component includes a support rod fixedly installed on the machine body.

[0023] By adding a potential energy interference shielding component to the flow guide box, the falling direction of the material is changed from vertical to horizontal. The push rod motor and the distance detector are linked to control the feeding height to always be close to the upper surface of the material, which completely eliminates the impact force generated by the free fall of the material. This allows the weighing device to obtain stable and accurate readings throughout the feeding process, solving the technical problem of drastic data fluctuations caused by the impact of falling material in traditional equipment.

[0024] By using a material return mechanism, residual materials in the pipeline are accurately recovered into the material bin after material is stopped, avoiding material waste and weighing errors. This application significantly improves weighing accuracy and equipment reliability while ensuring the flexibility of automatic proportioning of multi-components. Attached Figure Description

[0057] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] Example 1

[0059] like Figure 1 , Figure 2 and Figure 9 , Figure 10 As shown, the present application discloses an automatic ball dispensing and weighing device, comprising a body 1, multiple sets of feeding components 2 fixedly installed on the body 1, a sliding component 3, a flow guide box 4 and a weighing device 5 installed on the sliding component 3, and a measuring cylinder 6 located on the weighing device 5. The sliding component 3 controls the flow guide box 4, the weighing device 5 and the measuring cylinder 6 to move under different feeding components 2. The feeding components 2 convey materials to the inside of the measuring cylinder 6 through the flow guide box 4 and start and stop by feeding back weight data through the weighing device 5. Each set of feeding components 2 can carry small balls of different specifications or materials, thereby meeting the needs of different mixing processes. The sliding component 3 drives the flow guide box 4, the weighing device 5 and the measuring cylinder 6 to move as a whole, so that the same measuring cylinder 6 can receive materials output from different feeding components 2 in sequence, realizing automatic mixing and weighing of multi-component materials, avoiding the cumbersome operation of manual material changing or setting up multiple independent weighing mechanisms.

[0060] like Figures 3 to 8 As shown, in this embodiment, the feeding component 2 includes a support rod 21 fixedly installed on the machine body 1. The support rod 21 includes a support rod 211 mounted at a height on the machine body 1 and a height-adjustable locking block 212 mounted on the support rod 211. A screw conveyor 22 is rotatably mounted on multiple locking blocks 212. By adjusting the installation height of the locking block 212 on the support rod 211, the tilt angle of the screw conveyor 22 can be changed so that its discharge port 223 can be accurately aligned with the guide box 4 at different working positions.

[0061] Furthermore, the screw conveyor 22 includes a tube body 221 rotatably mounted on multiple locking blocks 212, a spiral lifting rod 222 rotatably mounted inside the tube body 221, a discharge port 223 located at one end of the tube body 221, and a discharge port valve 23 fixedly mounted on the discharge port 223. When the spiral lifting rod 222 rotates, it can lift the small balls of material in the material box assembly 24 upward along the tube body 221 and discharge them from the discharge port 223. The discharge port valve 23 is used to control the flow of material and, in conjunction with the feedback signal of the weighing device 5, achieves precise quantitative feeding.

[0062] It should be noted that there is a material conveying path between the discharge port 223 and the weighing device 5. In this embodiment, a precise compensation control logic based on the rotational speed of the screw lifting rod 222 is adopted. The system obtains the material conveying capacity of the screw lifting rod 222 at a unit rotational speed through pre-calibration, and calculates the total number of rotations of the screw lifting rod 222 in real time from the opening of the discharge port valve 23 to the weighing device 5 detecting the preset value, thereby estimating the amount of material that has been conveyed but has not yet fallen into the measuring cylinder 6. When the reading of the weighing device 5 reaches the preset value minus the residual amount, the control system issues a command to close the discharge port valve 23, and at the same time, the screw lifting rod 222 stops rotating. At this time, the residual material in the path is just replenished to the preset value, realizing precise quantitative feeding.

[0063] The other end of the tube body 221 is fixedly installed with a material box assembly 24. The material box assembly 24 includes a material box 241, a material level sensor 242 fixedly installed inside the material box 241, and a sliding plate 243. The material box 241 is used to store the small ball material to be put in. The sliding plate 243 is inclined to ensure that the material automatically slides to the inlet end of the screw conveyor 22 under the action of gravity, preventing the material from accumulating or being suspended. The material level sensor 242 monitors the material level in the material box 241 in real time. When the material level is lower than the set threshold, an alarm signal is issued to prompt the operator to replenish the material in time.

[0064] Furthermore, the discharge port valve 23 includes a valve body 231 fixedly installed on the discharge port 223 and a valve plate 232 rotatably installed on the valve body 231. A cylinder 233 is fixedly installed on the valve body 231, and a hinge 234 is rotatably installed on the output shaft of the cylinder 233. The other end of the hinge 234 is rotatably connected to the valve plate 232. An anti-collision pad 235 is fixedly installed on the valve body 231. The cylinder 233 drives the valve plate 232 to swing through the hinge 234, so that the valve plate 232 is in contact with or separated from the valve body 231, thereby realizing the rapid opening and closing of the discharge port. The anti-collision pad 235 plays a buffering role when the valve plate 232 is closed, reducing mechanical impact noise and wear.

[0065] like Figures 11 to 13As shown, in this embodiment, the sliding component 3 includes a sliding plate 31 slidably mounted on the machine body 1, a power component 32 for driving the sliding plate 31 to move, a vertical rod 33 fixedly mounted on the power component 32, and a mounting base 34 fixedly mounted on the vertical rod 33. The power component 32 will drive the sliding plate 31 to move, thereby allowing the sliding plate 31 to shuttle under different material boxes 241. The power component 32 can be a commonly used drive structure in the prior art, such as a rodless cylinder, a cable chain linear module, etc., preferably a cable chain linear module. A drive motor 35 corresponding to the two feeding components 2 is fixedly installed on the mounting base 34. A first coupling 36 is fixedly installed on the output shaft of the drive motor 35. A second coupling 37 corresponding to the first coupling 36 is fixedly installed at one end of the spiral lifting rod 222. When the sliding plate 31 moves to the working position of a certain feeding component 2, the second coupling 37 of the spiral lifting rod 222 on the feeding component 2 is exactly connected with the first coupling 36 on the drive motor 35. The drive motor 35 can then drive the spiral lifting rod 222 to rotate, realizing the material output of the feeding component 2. By having one drive motor 35 cooperate with multiple spiral lifting rods 222 in sequence, the number of motors is greatly reduced, and the equipment manufacturing cost and control complexity are reduced.

[0066] Specifically, a push rod assembly is mounted on the mounting base 34. The drive motor 35 is driven by the push rod assembly to move linearly. The push rod assembly can be a linear motor, cylinder, electric push rod, etc. That is, the push rod assembly drives the drive motor 35 and the first coupling 36 on it to move towards the second coupling 37. (Refer to...) Figure 11 Both the first coupling 36 and the second coupling 37 are provided with serrated grooves. Power transmission can be carried out by interlocking the serrated grooves. Moreover, even if the grooves are not in alignment during each docking, the inclined surface on the grooves can guide the connecting shaft to rotate so that it can complete the docking. Working principle: The sliding component 3 drives the guide box 4, weighing device 5 and measuring cylinder 6 to move sequentially to below the discharge port 223 of each feeding component 2. The weighing device 5 detects the cumulative weight of the material in the measuring cylinder 6 in real time. When a certain component is needed, the corresponding discharge port valve 23 opens. The spiral lifting rod 222, driven by the drive motor 35, lifts the small ball in the material box 241 and puts it into the measuring cylinder 6. The reading of the weighing device 5 increases accordingly. When the amount of the component added reaches the preset value, the discharge port valve 23 closes and the spiral lifting rod 222 stops rotating. Then the sliding component 3 drives the measuring cylinder 6 to move to the next feeding component 2. The above process is repeated until all components are added into the measuring cylinder 6 according to the set ratio, completing the automatic material distribution and weighing.

[0067] Example 2

[0068] like Figures 14 to 20As shown, based on Embodiment 1, the automatic ball dispensing and weighing device of this embodiment also includes a potential energy interference shielding component 7 installed on the guide box 4. During the process of the material ball falling directly from the discharge port 223 into the measuring cylinder 6, since the ball has a certain height falling, its gravitational potential energy is converted into kinetic energy. When it collides with the bottom of the measuring cylinder 6 or the material already inside, it will generate an impact force, causing the reading of the weighing device 5 to fluctuate violently in a short period of time, making it impossible to stably display the true weight value, which seriously affects the weighing accuracy and proportioning accuracy.

[0069] In this embodiment, the potential energy interference shielding component 7 receives the material passing through the inside of the guide box 4 and controls the material to enter the measuring cylinder 6 in a horizontal direction. The feeding height of the potential energy interference shielding component 7 changes with the height of the material inside the measuring cylinder 6 and always remains consistent with the height of the material. By changing the falling direction of the material from vertical to horizontal, the impact force in the vertical direction is completely eliminated. At the same time, by dynamically adjusting the feeding height to keep it close to the upper surface of the material, the possibility of the material falling from a height is further avoided, so that the material can enter the measuring cylinder 6 smoothly at almost zero speed, thereby ensuring the stability and accuracy of the reading of the weighing device 5 during the feeding process.

[0070] Furthermore, the potential energy interference shielding component 7 includes a connecting pipe 71 fixedly installed inside the flow guide box 4 and a conveying pipe 72 slidably installed on the connecting pipe 71. A push rod motor 73 is fixedly installed on the connecting pipe 71, and the output shaft of the push rod motor 73 is fixedly connected to the conveying pipe 72. A distance measuring detector 74 is fixedly installed on the conveying pipe 72. The distance measuring detector 74 measures the distance between the end of the conveying pipe 72 and the upper surface of the material in the measuring cylinder 6 in real time. The push rod motor 73 drives the conveying pipe 72 to slide up and down along the connecting pipe 71 according to the distance measurement result, so that the material outlet is always kept close to the material surface. As the material in the measuring cylinder 6 gradually increases, the conveying pipe 72 rises synchronously, ensuring that the material always enters the measuring cylinder 6 with an extremely low height difference throughout the weighing process, minimizing dynamic interference to the greatest extent.

[0071] It should be noted that inside the measuring cylinder 6, the material will naturally accumulate to form a conical structure. However, the process of the material sliding from the top of the cone to the bottom is a redistribution of the material within the system. The force generated by the relative motion between particles during this process is an internal force of the system and will not change the total vertical force borne by the weighing device 5. Therefore, it will not affect the stability of the weighing result.

[0072] Furthermore, the potential energy interference shielding component 7 also includes a flow guiding mechanism 75 installed on the conveying pipe 72 to convert the material direction to a horizontal direction. The flow guiding mechanism 75 includes a reversing box 751 rotatably mounted on the conveying pipe 72 and a conical flow guiding groove 752 disposed inside the reversing box 751. The flow guiding groove 752 is provided with a plurality of discharge holes 753 arranged in a circular array. A flow guiding pipe 754 with a horizontally positioned end is fixedly installed on the discharge hole 753. The material ball enters the reversing box 751 from the conveying pipe 72. Then, it falls into the conical guide channel 752 and disperses in all directions along the guide channel 752 under the action of gravity. It enters each guide pipe 754 through the discharge hole 753 and is finally discharged from the horizontal end of the guide pipe 754. This structure changes the falling direction of the material from vertical to horizontal, eliminating the vertical impact force when the material enters the measuring cylinder 6. At the same time, through the circumferential distribution of multiple guide pipes 754, the material can be evenly dispersed to various areas of the measuring cylinder 6, avoiding the excessively high cone formed by local accumulation, which would affect subsequent feeding.

[0073] It is worth noting that the potential energy interference shielding component 7 also includes a pneumatic assembly 76 that provides power for air blowing to materials within the guide channel 752. The pneumatic assembly 76 includes an air chamber 761 located inside the reversing box 751, multiple extension pipes 762 communicating with the air chamber 761 and located inside the guide channel 752, an air inlet pipe 763 fixedly connected to the air chamber 761, a connecting ring 764 fixedly installed on the conveying pipe 72, a sealing plate 765 rotatably and sealingly connected to the connecting ring 764, a connector 766 connected to the connecting ring 764, and an air pump system connected to the connector 766. For materials with relatively high mass... Lightweight or high-friction material balls may not be able to pass smoothly through the guide pipe 754 horizontally by gravity alone. The air pump system introduces compressed gas into the air chamber 761 through the connector 766, connecting ring 764 and air inlet pipe 763. The gas forms a directional airflow in the guide groove 752 through the extension pipe 762, providing auxiliary thrust for the material balls and ensuring that they smoothly enter the guide pipe 754 and are discharged from the horizontal end. The rotational sealing structure of the connecting ring 764 and the sealing plate 765 ensures that the air supply line remains connected when the reversing box 751 is rotated to adjust its direction, without affecting the continuous supply of airflow.

[0074] In this embodiment, the potential energy interference shielding component 7 further includes a material return mechanism 77. The material return mechanism 77 includes a first solenoid valve 771 fixedly installed at the end of the guide pipe 754, a transfer pipe 772 fixedly installed on and connected to the guide pipe 784, a second solenoid valve 773 fixedly installed on the transfer pipe 772, and a return pipe 774 fixedly installed on the second solenoid valve 773. A return box 775 is fixedly installed on the conveying pipe 72, and a connecting ring 776 is rotatably installed on the return box 775. Multiple return pipes 774 are fixedly connected to the connecting ring 776 and connected to the return box 775. A connecting nozzle 777 is provided on the return box 775. A vacuum cleaner is installed on the sliding component 3. The input end of the vacuum cleaner is connected to the connecting nozzle 777, and the output end of the vacuum cleaner points to the feeding component 2. During normal feeding, the first solenoid valve 771 is open. When the first solenoid valve 771 is closed, the material ball is discharged horizontally from the guide pipe 754 into the measuring cylinder 6. When the weighing device 5 detects that the amount of the current component added has reached the preset value, the control system immediately closes the first solenoid valve 771. At this time, some material that has not been discharged will still remain in the reversing box 751 and the guide pipe 754. If it is not handled, this part of the material may fall into the measuring cylinder 6 when switching stations or stopping the equipment, causing weighing errors. At this time, the pneumatic component 76 continues to work, and the second solenoid valve 773 opens and the vacuum cleaner is started. Under the combined action of the airflow thrust and the vacuum cleaner negative pressure, the remaining material ball enters the return box 775 through the transfer pipe 772 and the return pipe 774, and is finally sent back to the corresponding material box 241 through the output end of the vacuum cleaner, realizing accurate material recovery and avoiding material waste and weighing deviation.

[0075] The potential energy interference shielding component 7 also includes a drive component 78 mounted on the delivery pipe 72 to drive the reversing box 751 to rotate. The drive component 78 includes a first gear 781 fixedly mounted on the reversing box 751, a motor 782 fixedly mounted on the delivery pipe 72, and a second gear 783 fixedly mounted on the output shaft of the motor 782 and meshing with the first gear 781. The motor 782 drives the reversing box 751 to rotate through the meshing of the second gear 783 with the first gear 781. On the one hand, while the pneumatic component 76 is blowing air... During operation, the centrifugal force generated by the rotation helps to throw the small balls of material in the guide channel 752 toward the discharge holes 753 around the perimeter, improving the discharge efficiency. This is especially suitable for materials with high viscosity or irregular shape. On the other hand, by controlling the rotation angle of the reversing box 751, multiple guide tubes 754 can form a ring or spiral discharge trajectory in the measuring cylinder 6, avoiding excessive accumulation of material in the central area of ​​the measuring cylinder 6 to form a high cone, ensuring the uniformity of material distribution inside the measuring cylinder 6, thereby improving the stability of the weighing process and the accuracy of the final proportion.

[0076] Compared to the method of calculating and compensating for residual material in the conveying path by rotational speed, this embodiment changes the material movement direction from vertical to horizontal by using the potential energy interference shielding component 7, and keeps the feeding height close to the upper surface of the material in the measuring cylinder. This fundamentally eliminates the impact force generated by the free fall of the material, enabling the weighing device to reflect the actual amount added in real time and stably. High-precision control can be achieved without relying on complex algorithm compensation. It is suitable for ideal working conditions where the amount of material in the path is unstable. When the material characteristics change or the conveying efficiency fluctuates due to wear after long-term operation of the equipment, the compensation accuracy remains stable, and it has higher control robustness and long-term stability.

[0077] In this embodiment, the material outlet is always kept close to the upper surface of the material in the measuring cylinder 6 by the linkage control of the push rod motor 73 and the distance detector 74. The flow guiding mechanism 75 changes the falling direction of the material from vertical to horizontal, completely eliminating the vertical impact force during the falling process. The pneumatic component 76 provides auxiliary power for the material discharge, and the drive component 78 drives the reversing box 751 to rotate, so as to achieve uniform material distribution. The material return mechanism 77 accurately recovers the material remaining in the pipeline after the material stops and returns it to the material box 241, preventing material waste and weighing errors. This allows the weighing device 5 to obtain stable and accurate readings throughout the weighing process, effectively solving the problem of data fluctuation caused by the impact of falling material in traditional weighing equipment, and greatly improving the automatic proportioning accuracy of multi-component small ball materials and the reliability of equipment operation.

[0078] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
