Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chip capacitor production equipment, and in particular to a slurry spreading mechanism for sealing chip capacitors. Background Technology
[0002] Traditional surface mount capacitor (SMT) end-sealing slurry spreading equipment simply spreads the slurry evenly and performs the sealing process. The spreading process involves: first, a scraper leveling the slurry in the slurry tray; then, a screw drives the slurry tray beneath the scraper to move back and forth while the scraper remains stationary. Because the gap between the scraper and the slurry tray is very small, the relative movement between them ensures a uniform slurry thickness on the tray surface.
[0003] However, since the amount of slurry in the slurry pan is generally small, it is difficult to ensure that a slurry layer of the same thickness can be formed on the surface of the slurry pan during one relative movement between the scraper and the slurry pan. Multiple relative movements between the scraper and the slurry pan are required to form a slurry layer of the required thickness, which greatly reduces the slurry spreading speed of the slurry spreading equipment. Utility Model Content
[0004] The purpose of this invention is to propose a slurry spreading mechanism for sealing chip capacitors, which can effectively improve the slurry spreading speed of the slurry spreading mechanism and overcome the shortcomings of the prior art.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A slurry spreading mechanism for sealing chip capacitors includes a slurry tray, a slurry spreading assembly, and a mounting bracket. The mounting bracket is mounted on top of the slurry tray, and the slurry tray can move horizontally relative to the mounting bracket. The slurry spreading assembly is mounted on the front side of the mounting bracket.
[0007] The slurry spreading assembly includes a slurry collecting knife, a slurry spreading knife, and a cleaning knife arranged sequentially from front to back along the moving direction of the slurry tray. The slurry collecting knife and the slurry spreading knife can move up and down relative to the mounting bracket, and the slurry collecting knife is used to collect and accumulate slurry at one end of the slurry tray, and the slurry spreading knife is used to spread the accumulated slurry into a slurry layer.
[0008] The cleaning blade is used to clean the back of the slurry spreading blade.
[0009] Preferably, the cleaning knife is an air knife.
[0010] Preferably, the cleaning blade is a scraper;
[0011] The scraper moves up and down relative to the mounting bracket, and the end of the scraper abuts against the back of the slurry spreading blade.
[0012] Preferably, the slurry tray includes an immersion tank and a recovery tank arranged sequentially from front to back.
[0013] Preferably, the horizontal cross-sectional shape of the slurry-collecting knife is U-shaped, and the opening of the slurry-collecting knife faces the slurry-spreading knife.
[0014] Preferably, it also includes a laser detector, which is disposed on the rear side of the cleaning blade, and the laser detector is used to detect the thickness of the slurry layer;
[0015] The mounting bracket includes two support frames and a back plate. The two support frames are respectively protrudingly disposed on both sides of the paddle tray. The rotating end of the back plate is rotatably connected to one of the support frames through a bearing seat. The adjusting end of the back plate is detachably mounted to the other support frame through screws. The laser detector is movable along the length direction of the back plate and mounted behind the back plate.
[0016] The technical solution provided by this utility model can include the following beneficial effects:
[0017] 1. The slurry spreading assembly in this solution includes a slurry collecting blade and a slurry spreading blade, both of which can move up and down relative to the mounting bracket. During the slurry spreading process, the slurry collecting blade is first used to accumulate the slurry at the rear end of the slurry tray, and then the spreading blade is used to spread the accumulated slurry evenly according to the required thickness, thereby effectively accelerating the slurry preparation speed of the impregnation process.
[0018] 2. During the slurry spreading process, slurry may adhere to the back of the slurry spreading knife. Therefore, in order to prevent slurry waste and avoid frequent addition of slurry to the slurry tray, this solution also adds a cleaning knife to the rear side of the slurry spreading knife. The cleaning knife can effectively clean the slurry adhering to the back of the slurry spreading knife and return it to the inside of the slurry tray to avoid slurry waste.

[0022] Among them: slurry tray 512, slurry soaking tank 5121, recovery tank 5122;
[0023] Slurry spreading component 513, slurry collecting knife 5131, slurry spreading knife 5132, scraper 5133;
[0024] Mounting bracket 518, support frame 5181, back plate 5182, bearing seat 5183, screw 5184;
[0025] Laser detector 519. Detailed Implementation
[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] This technical solution provides a slurry spreading mechanism for sealing chip capacitors, including a slurry tray 512, a slurry spreading component 513, and a mounting bracket 518. The mounting bracket 518 is mounted on the top of the slurry tray 512, and the slurry tray 512 can move horizontally relative to the mounting bracket 518. The slurry spreading component 513 is mounted on the front side of the mounting bracket 518.
[0028] The slurry spreading assembly 513 includes a slurry collecting blade 5131, a slurry spreading blade 5132, and a cleaning blade arranged sequentially from front to back along the moving direction of the slurry tray 512. The slurry collecting blade 5131 and the slurry spreading blade 5132 can move up and down relative to the mounting bracket 518, and the slurry collecting blade 5131 is used to collect and accumulate slurry at one end of the slurry tray 512, and the slurry spreading blade 5132 is used to spread the accumulated slurry into a slurry layer.
[0029] The cleaning blade is used to clean the back of the slurry spreading blade 5132.
[0030] like Figure 1-3 As shown, in this scheme, the slurry spreading component 513 is mounted above the slurry tray 512 via a mounting bracket 518, and the slurry collecting blade 5131 and the slurry spreading blade 5132 can move up and down relative to the mounting bracket 518 respectively. This scheme allows the slurry to be first accumulated at the rear end of the slurry tray 512 using the slurry collecting blade 5131, and then the slurry spreading blade 5132 to spread the accumulated slurry evenly according to the required thickness, thus effectively accelerating the slurry preparation speed during the impregnation process. If only the slurry spreading blade 5132 is used to prepare the slurry layer, the slurry tray 512 and the slurry spreading blade 5132 need to be moved repeatedly to form the required slurry layer thickness, greatly reducing the slurry spreading speed of the slurry spreading equipment.
[0031] During the slurry spreading process of the slurry spreading knife 5132, slurry may adhere to the back of the slurry spreading knife 5132. Therefore, in order to prevent slurry waste and avoid frequent addition of slurry to the slurry tray 512, this solution also provides a cleaning knife on the rear side of the slurry spreading knife 5132. The cleaning knife can effectively clean the slurry adhering to the back of the slurry spreading knife 5132 and return it to the inside of the slurry tray 512 to avoid slurry waste.
[0032] To further clarify, the cleaning knife is an air knife.
[0033] In one embodiment of this technical solution, the cleaning knife can be an air knife (not shown in the figure). By blowing air onto the back of the slurry spreading knife 5132, the slurry on the back of the slurry spreading knife 5132 can be effectively blown away and the slurry falls back into the slurry tray 512.
[0034] To further clarify, the cleaning blade is a scraper 5133;
[0035] The scraper 5133 moves up and down relative to the mounting bracket 518, and the end of the scraper 5133 abuts against the back of the slurry spreading blade 5132.
[0036] In another embodiment of this technical solution, the cleaning blade is a scraper 5133, such as... Figure 3 As shown, scraping the slurry off the back of the slurry spreading knife 5132 by scraping it off with the scraper 5133 can also effectively avoid slurry waste.
[0037] To further explain, the slurry tray 512 includes an immersion tank 5121 and a recovery tank 5122 arranged sequentially from front to back.
[0038] As a preferred embodiment of the above, since the slurry may be contaminated by dust in the air or by the falling of chip capacitors from the carrier plate during the impregnation process, the dust or the falling chip capacitors can be collected on the back of the blade by the slurry spreading blade 5132, then cleaned by the cleaning blade and recycled into the inside of the recycling tank 5122. Finally, by screening, cleaning and reusing the chip capacitors in the recycling tank 5122, product waste can be effectively avoided.
[0039] To further explain, the horizontal cross-sectional shape of the slurry-collecting blade 5131 is U-shaped, and the opening of the slurry-collecting blade 5131 faces the slurry-spreading blade 5132.
[0040] In this way, the slurry can be effectively deposited.
[0041] Furthermore, it also includes a laser detector 519, which is disposed on the rear side of the cleaning blade and is used to detect the thickness of the slurry layer;
[0042] The mounting bracket 518 includes two support frames 5181 and a back plate 5182. The two support frames 5181 are respectively protruding on both sides of the paddle tray 512. The rotating end of the back plate 5182 is rotatably connected to one of the support frames 5181 through a bearing seat 5183. The adjusting end of the back plate 5182 is detachably mounted to the other support frame 5181 through a screw 5184. The laser detector 519 is movably mounted behind the back plate 5182 along the length direction of the back plate 5182.
[0043] To enhance the intelligence of the slurry spreading mechanism, this solution also installs a laser detector 519 on the back of the mounting bracket 518 to detect the thickness of the slurry layer, thereby improving the controllability of the slurry spreading mechanism.
[0044] Furthermore, to improve the detection accuracy of the laser detector 519 and ensure its horizontal movement on the backplate 5182, this solution also optimizes the mounting structure of the backplate 5182, such as... Figure 3 As shown, the installation of the back plate 5182 by means of the cooperation of the bearing seat 5183 and the screw 5184 is beneficial to adjust and realize the horizontal setting of the back plate 5182, thereby ensuring the horizontal movement of the laser detector 519 on the back plate 5182.
