Description

[0023] In capacitor manufacturing, a gold plating process is performed. This involves melting materials such as zinc wire, zinc-tin alloy wire, or composite zinc-tin wire, then spraying them onto the capacitor's surface using high-pressure air to create fine particles, thus meeting the capacitor's performance requirements. After the gold plating process, excess metal particles and oxides remaining on the capacitor surface need to be removed. This can be achieved through sandblasting, which uses a high-speed airflow to propel fine abrasive particles onto the capacitor surface, causing the surface deposits to be impacted and peeled off, thereby improving the cleanliness of the capacitor's surface. Currently, existing sandblasting equipment has a relatively limited range of sandblasting modes and cannot meet the diverse cleanliness requirements of different products. Therefore, adapting to the different cleanliness levels required by various products is a pressing technical problem that needs to be solved.

[0024] To address the problems existing in the aforementioned related technologies, this utility model provides a sandblasting device 10 and a capacitor production line, combined with... Figures 1 to 3 As shown, a sandblasting device 10 includes an image acquisition element, a controller, and multiple sandblasting components 20, wherein: the image acquisition element is used to acquire information about the particles to be cleaned on the surface of a capacitor and is communicatively connected to the controller; each sandblasting component 20 includes a sand storage tank 30 and an output pipe 40 connected to the sand storage tank 30, the sand storage tank 30 contains sandblasting particles 31, and the median particle size of the sandblasting particles 31 in the sand storage tanks 30 of at least two of the sandblasting components 20 is different; wherein, the controller is used to select the output pipe 40 of the corresponding sandblasting component 20 to be turned on according to the information about the particles to be cleaned from the image acquisition element.

[0025] The image acquisition element is used to acquire information about the particles to be cleaned on the capacitor surface. It communicates with the controller to collect key information such as the adhesion density, particle size, and adhesion thickness of the particles on the capacitor surface in real time and with high accuracy. This provides data support for subsequent selection of appropriate sandblasting particles and the sand storage tank 30. Sandblasting particles 31 of different sizes offer diverse cleaning intensity options. Different impact intensities are achieved based on the particle size differences to meet the cleaning needs of particles with varying degrees of adhesion, thus enabling graded treatment of light, medium, and heavy adhesion particles. For example, large-diameter sandblasting particles 31 can efficiently remove large particles, while small-diameter sandblasting particles 31 can precisely remove fine, thin adhesions. By setting up sand storage tanks 30 containing sandblasting particles 31 of different median diameters, and using the image acquisition component to acquire information about the particles to be cleaned, the controller selects the corresponding sand storage tank 30 based on this information and activates the corresponding output pipeline 40 to achieve sandblasting operations that precisely match the cleaning requirements. This enables intelligent adaptation to different cleaning levels, improving the consistency and stability of capacitor surface treatment. Meanwhile, image recognition technology is used to automatically acquire information about the attached particles, and the controller accurately matches the sand storage tank 30 with the corresponding median diameter sandblasting particles 31, thereby realizing an automated operation process, effectively reducing manual intervention, reducing operational errors, and significantly improving the overall intelligence level of the production line.

[0026] The image acquisition component is used to acquire information about the particles to be cleaned on the capacitor surface. This information can include a combination of one or more of the following: the position coordinates of the particles, particle size, particle shape, distribution density, and distribution thickness. For example, a sand storage tank 30 corresponding to sandblasting particles 31 with a median particle size of 600 mesh can be used to clean areas with a surface particle size of 500 to 700 mesh and a surface particle thickness of 0.35 mm to 0.6 mm; a sand storage tank 30 corresponding to sandblasting particles 31 with a median particle size of 900 mesh can be used to clean areas with a surface particle size of 800 to 1000 mesh and a surface particle thickness of 0.15 mm to 0.35 mm; and a sand storage tank 30 corresponding to sandblasting particles 31 with a median particle size of 1100 mesh can be used to clean areas with a surface particle size greater than 1000 mesh and a surface particle thickness less than 0.15 mm. These are just examples and are not specific limitations.

[0027] The functions of the image acquisition element and the controller are easy to understand, and their specific functions are mature technologies in related fields. Their structure is not shown in the figure.

[0028] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 The sandblasting device 10 also includes a sandblasting main pipeline 50, and the output pipelines 40 of the plurality of sandblasting components 20 are respectively connected to the sandblasting main pipeline 50; the sandblasting component 20 also includes a first valve 41 disposed on the output pipeline 40, and the first valve 41 is communicatively connected to the controller.

[0029] The main sandblasting pipeline 50 integrates multiple output pipelines 40, unifying the sandblasting delivery path and ensuring consistent sandblasting direction and coverage when switching between different sandblasting components 20. This avoids overlapping or omissions in cleaning areas caused by multiple dispersed pipelines, improving the uniformity of capacitor surface treatment. The first valve 41 of the target sandblasting component 20 is opened individually, while the first valves 41 of other components are closed, preventing the mixing of sandblasting particles 31 of different sizes caused by simultaneous sandblasting of multiple components. The communication connection design ensures automated and rapid response of the first valve 41 opening and closing, eliminating the need for manual operation, improving production efficiency, and reducing the risk of valve misoperation.

[0030] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 The sandblasting device 10 also includes a second valve 51 located on the main sandblasting pipeline 50, which is communicatively connected to the controller. The second valve 51 serves as the main control switch for the sandblasting system. During maintenance or shutdown, the second valve 51 can be closed via the controller, eliminating the need to close the first valves 41 of each component individually, simplifying maintenance operations and reducing maintenance time costs. If a first valve 41 malfunctions and cannot be closed, the second valve 51 can urgently shut off the main pipeline to prevent uncontrolled sandblasting and improve system operational safety.

[0031] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 At least one of the output pipes 40 of the sandblasting assembly 20 is a straight pipe structure 42; at least one of the output pipes 40 of the sandblasting assembly 20 includes a bent pipe structure 43; wherein, the median particle size of the sandblasting particles 31 in the sand storage tank 30 corresponding to the bent pipe structure 43 is larger than the median particle size of the sandblasting particles 31 in the sand storage tank 30 corresponding to the straight pipe structure 42. The bent pipe structure 43 increases the flow resistance of the sandblasting particles 31, causing smaller particles to easily deposit at the bend, affecting the continuity and uniformity of sandblasting; the use of sandblasting particles 31 with a larger median particle size in the bent pipe structure 43 can effectively reduce the risk of clogging, improve flow smoothness, and ensure the stability of the sandblasting process; the straight pipe structure 42 is suitable for smaller particles, reduces wear and energy loss, and balances sandblasting accuracy and efficiency.

[0032] In some embodiments, please refer to the following for details. Figure 1 The sandblasting device 10 also includes a sandblasting nozzle 60 located at the end of the main pipeline away from the sand storage tank 30. The position of the sandblasting nozzle 60 is adapted to the distance between the capacitor surface to be treated, ensuring appropriate sandblasting impact force and avoiding surface damage due to excessive distance or reduced cleaning efficiency due to excessive distance.

[0033] In some embodiments, please refer to the following for details. Figure 1 , Figure 2The sandblasting assembly 20 also includes a first pressure sensor 71 connected to the sand storage tank 30. This sensor monitors the air pressure within the sand storage tank 30 in real time. Air pressure directly determines the spray speed and flow rate of the sandblasting particles 31. If the pressure is insufficient, it can promptly send feedback to the controller or remind the operator to replenish the air pressure, preventing a decrease in cleaning power due to insufficient pressure. If the pressure is too high, it can trigger pressure relief or shutdown protection to prevent excessive impact damage to the capacitor surface from the sandblasting particles 31.

[0034] In some embodiments, please refer to the following for details. Figure 1 The sandblasting device 10 also includes a cleaning chamber 80 and a suction component 81 communicating with the cleaning chamber 80. The cleaning chamber 80 is used to hold the capacitor to be cleaned, and the suction component 81 is used to suction out particulate matter from the cleaning chamber 80. The suction component 81 operates simultaneously with the sandblasting operation, promptly removing scattered particulate matter from the cleaning chamber 80. The particulate matter may include sandblasting particles 31 and metal particles detached from the capacitor surface, maintaining a clean environment inside the cleaning chamber 80 and preventing secondary pollution.

[0035] In some embodiments, please refer to the following for details. Figure 1 The sandblasting device 10 also includes a recovery tank 82 connected to the suction component 81, which is located at the discharge end of the suction component 81. The recovery tank 82 is used to collect the sandblasting particles 31 and metal debris discharged by the suction component 81, realizing resource recycling. The sandblasting particles 31 can be screened and then returned to the sand storage tank 30 for subsequent operations, reducing consumable costs. The metal debris is centrally recycled to avoid pollution caused by mixing into the environment.

[0036] Specifically, the recycling tank 82 is equipped with a screening structure that can classify the recycled sandblasting particles 31 according to their particle size, and only transport particles that meet the set median particle size range to the sand storage tank 30 for reuse, ensuring the consistency of the sandblasting effect; while metal scraps are discharged through an independent channel and stored centrally.

[0037] In some embodiments, please refer to the following for details. Figure 1 , Figure 3 The sandblasting device 10 also includes a second pressure sensor 72 connected to the recovery tank 82. When the recovery tank 82 is full, the pressure will increase due to particle accumulation. The sensor can trigger an early warning to remind the user to clean the tank and prevent the suction component 81 from being damaged due to excessive pressure. If the pipeline is blocked, such as due to particle agglomeration, the pressure will fluctuate abnormally. The sensor can promptly report the fault, allowing operators to quickly troubleshoot and preventing the suction component 81 from stopping and affecting the sandblasting operation.

[0038] This utility model also provides a capacitor production line, including any of the above-described sandblasting devices 10.

[0039] For the specific structure of the sandblasting device 10, please refer to any of the above-mentioned embodiments and accompanying drawings of the sandblasting device 10, which will not be repeated here.

[0040] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
