Description

Technical Field

[0001] This application relates to the technical field of MLCC electroplating and sorting, and in particular to a sorting machine for MLCC sorting. Background Technology

[0002] MLCC (Multi-layer Ceramic Capacitor) is formed by stacking ceramic dielectric films with printed electrodes (internal electrodes) in an alternating manner, sintering them at high temperature to form a ceramic block, and then sealing the two ends of the ceramic block with metal layers (external electrodes).

[0003] The manufacturing process of MLCCs generally involves processes such as batching, casting, printing, lamination, pressing, cutting, glue removal, sintering, chamfering, end sealing, end firing, and electroplating. During the electroplating process, a steel ball + MLCC combination is typically used, with the steel ball serving as the plating medium. After electroplating, various particulate matter, including MLCCs, waste products, adhered wafers of different sizes, recyclable steel balls that can be reused, worn-out scrap steel balls, and scrap steel balls stuck together, is mixed together. Screening equipment is needed to separate these various particulate matter.

[0004] Traditional screening equipment has low sorting efficiency, and the sorted products often contain stuck-on pieces. After the products come off the production line, manual screening and manual magnetic suction of residual plating products are required repeatedly until they are qualified, resulting in low sorting efficiency.

[0064] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, a detailed description of specific embodiments of this application is provided below. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0065] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0067] This application provides a sorting machine for MLCC sorting, used to separate electroplated MLCCs from steel balls.

[0068] like Figure 1 As shown, in one embodiment, the sorting machine 1000 for MLCC sorting of this application includes a frame 900, and a first material distribution mechanism 100, a first product screening mechanism 200, a second product screening mechanism 300, a receiving box 400, and a first plating-related product screening mechanism 500 mounted on the frame 900.

[0069] like Figure 1 and Figure 2 As shown, the first material distribution mechanism 100 includes an inclined first separation disk 110 and a first vibrator 120 fixedly connected to the first separation disk 110. The upper and lower ends of the first separation disk 110 are respectively provided with a first product outlet 130 and a first plating filler outlet 140. In this embodiment, the first vibrator 120 is preferably located below the first separation disk 110. The first vibrator 120 causes the inclined first separation disk 110 to vibrate. This vibration has both vertical and horizontal components, causing the spherical plating filler to roll down to the lower first plating filler outlet 140 due to gravity. The MLCC, being a square block structure, gradually moves upwards to the first product outlet 130 during vibration, thereby achieving separation of the MLCC from the plating filler.

[0070] like Figure 1 and Figure 6 As shown, the first product screening mechanism 200 includes a sieve plate 210 horizontally disposed below the first product outlet 130. The sieve plate 210 can be directly disposed below the first product outlet 130 to directly receive MLCCs falling from the first product outlet 130. In other embodiments, other collection mechanisms, conversion mechanisms, or screening mechanisms may also be provided below the first product outlet 130 to further collect, convert, or screen the MLCCs falling from the first product outlet 130 before moving them to the sieve plate 210 located outside the first product outlet 130.

[0071] like Figure 6 As shown, the first product screening mechanism 200 also includes a waste discharge trough 220 disposed at the end of the sieve plate 210, a guide plate 230 disposed below the sieve plate 210, and a second vibrator 240 fixedly connected to the guide plate 230. The sieve plate 210 has strip-shaped holes for MLCCs to fall through. In this embodiment, the sieve plate 210 and the guide plate 230 are fixedly connected to each other; therefore, the second vibrator 240 can simultaneously drive the sieve plate 210 and the guide plate 230 to vibrate. Preferably, the second vibrator 240 is fixed below the guide plate 230.

[0072] In this embodiment, the second vibrator 240 vibrates, causing the MLCCs and waste products that fall onto the screen plate 210 to move forward. During this forward movement, the MLCCs fall through the slotted holes and onto the guide plate 230, moving forward with the vibration of the guide plate 230. However, the stuck-on sheets and waste sheets, due to their large size, will continue to move forward on the screen plate 210 until they reach the waste discharge trough 220. The waste discharge trough 220 can be a collection trough located at the end of the screen plate 210, and this collection trough can also have a drawer-type removal function. In a preferred embodiment, the waste discharge trough 220 can also be further... Figure 6 The diagram shows a discharge outlet, from which a collection container can be installed to collect waste.

[0073] like Figure 1 , Figure 6 and Figure 8 As shown, the second product screening mechanism 300 includes a vibratory feeder 310 disposed below the end of the guide plate 230. A product screen plate 320 is disposed on the vibratory feeder 310, and the product screen plate 320 has through holes for MLCCs to fall through. A discharge trough 330 is disposed below the product screen plate 320. In this embodiment, the vibratory feeder 310 receives MLCCs falling from the end of the guide plate 230 and vibrates them to allow them to pass through the through holes and fall into the discharge trough 330 below. The MLCCs entering the discharge trough 330 further fall into the receiving box 400 below the discharge trough 330.

[0074] In this embodiment, the through holes on the product screen plate 320 are mainly used to screen out linear and parallel adhesive pieces that may pass through the strip holes of the screen plate 210. The through holes are set to be larger than the width of the MLCC, so that the MLCC can fall out of the through holes during vibration. The through holes can be square, round, polygonal, irregularly shaped, etc., and are slightly larger than the width of the MLCC. Preferably, the through holes in this embodiment are round. In a preferred embodiment, the center hole distance between two through holes is less than twice the thickness of the MLCC, which makes the stress position of the linear adhesive piece longer, making it even more impossible for it to leak into the discharge trough 330 through the through holes.

[0075] like Figures 10 to 12As shown, the first plating sample screening mechanism 500 includes a receiving tray 510 and a third vibrator 520 fixedly connected to the receiving tray 510. The receiving tray 510 is located below the first plating sample discharge outlet 140. In this embodiment, the receiving tray 510 can be directly located below the first plating sample discharge outlet 140 to directly receive the plating samples falling from the first plating sample discharge outlet 140. In other embodiments, other collection mechanisms, conversion mechanisms, or screening mechanisms may also be provided below the first plating sample discharge outlet 140. After further collection, conversion, or screening of the plating samples falling from the first plating sample discharge outlet 140, they can be moved to the receiving tray 510 located outside the first plating sample discharge outlet 140.

[0076] The third vibrator 520 is preferably located below the receiving tray 510, and it moves the plating sample forward on the receiving tray 510 through horizontal vibration. In the direction of the plating sample's movement, a first plating sample collection area 511 and a second plating sample collection area 512 are sequentially formed on the receiving tray 510, and the first plating sample collection area 511 and the second plating sample collection area 512 are isolated from each other. Above the first plating sample collection area 511, the receiving tray 510 is provided with a first plating sample screen plate 531, which has screen holes for smaller plating samples to pass through.

[0077] In this embodiment, plating products with a size smaller than the screen holes on the first plating product screen plate 531 fall from the screen holes into the first plating product collection area 511 as they move forward, while plating products with a size larger than the screen holes on the first plating product screen plate 531 move forward into the second plating product collection area 512.

[0078] The first plating sample collection area 511 and the second plating sample collection area 512 can have independent collection functions, such as being a drawer type, or they can be... Figure 11 and Figure 12 Each of the items shown has a discharge port, and a collection container can be installed at the discharge port to collect the plating material inside.

[0079] The working process of the sorting machine for MLCC sorting in this embodiment of the application is as follows:

[0080] The electroplated MLCC and the plating dos are introduced into the first separation plate 110 of the first material distribution mechanism 100. The first separation plate 110 is vibrated by the first vibrator 120, causing the plating dos to be discharged downward from the first plating dos discharge port 140, and the MLCC to be discharged upward from the first product discharge port 130.

[0081] MLCCs, adhered chips, and waste chips discharged from the first product outlet 130 fall onto the sieve plate 210 of the first product screening mechanism 200. The second vibrator 240 drives the sieve plate 210 to vibrate, causing the MLCCs, adhered chips, and waste chips to move forward on the sieve plate 210. The MLCCs fall from the strip holes on the sieve plate 210 into the guide plate 230, while the adhered chips and waste chips move all the way to the waste discharge trough 220 at the end of the sieve plate 210. The MLCCs that fall into the guide plate 230 move forward to the end of the guide plate 230 under the vibration of the second vibrator 240.

[0082] MLCCs fall from the end of the guide plate 230 into the vibrating plate 310 of the second product screening mechanism 300. The vibrating plate 310 causes normal MLCCs to fall from the through holes of the product screen plate 320 into the discharge trough 330 below, while the straight-line adhesive sheets and the side-by-side adhesive sheets are left on the product screen plate 320.

[0083] Normal MLCCs that fall into the discharge trough 330 are further fed into the receiving box 400, completing the collection of MLCCs;

[0084] The plating products discharged from the first plating outlet 140 fall onto the receiving tray 510 of the first plating product screening mechanism 500. Driven by the vibration of the third vibrator 520, the plating products move forward on the receiving tray 510. As the plating products pass through the first plating product screen plate 531, smaller plating products fall through the screen holes into the first plating product collection area 511 below, while larger plating products move forward to the second plating product collection area 511, thus completing the classification and collection of plating products of different sizes.

[0085] The sorting machine for MLCC sorting in this embodiment of the application separates MLCCs from the plating substrates through a first material distribution mechanism; filters out adhered and waste MLCCs through the strip-shaped holes of the first product screening mechanism; and filters out linear and parallel adhered MLCCs through the through holes in the vibrating plate of the second product screening mechanism, thereby obtaining qualified MLCCs. The sorting machine for MLCC sorting in this embodiment of the application also achieves the sorting of plating substrates of different sizes by setting a first plating substrate screen plate in the first plating substrate screening mechanism. The sorting machine for MLCC sorting in this embodiment of the application has advantages such as high sorting efficiency, less manual operation, and high sorting accuracy, and low sorting cost, which is conducive to its widespread application.

[0086] Since the MLCCs falling from the first product outlet 130 of the first separation tray 110 may contain a small amount of plating filler, in order to further screen and separate the plating filler, in a preferred embodiment, such as... Figure 1 and Figure 13As shown, the sorting machine 1000 for MLCC sorting also includes a second material distribution mechanism 600. The second material distribution mechanism 600 includes an inclined second separation disk 610 and a fourth vibrator 620 fixedly connected thereto. The upper and lower ends of the second separation disk 610 are respectively provided with a second product outlet 630 and a second plating product outlet 640. In this embodiment, the second material distribution mechanism 600 is disposed between the first product outlet 130 and the first product screening mechanism 200, and the sieve plate 210 is disposed below the second product outlet 630.

[0087] Preferably, the fourth vibrator 620 is positioned below the second separation disk 610. In this embodiment, during the vibration of the second separation disk 610 driven by the fourth vibrator 620, the spherical plating material rolls down to the second plating material discharge port 640 below due to gravity. The MLCC, being a square block structure, gradually moves upwards to the second product discharge port 630 during vibration, thereby achieving the separation of the MLCC from the residual plating material.

[0088] Preferably, the second separation disc 610 can be triangular in shape, with the second product outlet 630, the second plating outlet 640, and the position below the first product outlet 130 located at the three corners of the triangle.

[0089] Since some defective products still exist among the products discharged from the first plating outlet 140, in order to remove the defective products, in a preferred embodiment, such as... Figure 1 and Figure 14 As shown, the sorting machine 1000 for MLCC sorting also includes a second plating screening mechanism 700. The second plating screening mechanism 700 includes a third separating disc 710 disposed below the first plating outlet 140 and a fifth vibrator 720 fixedly connected thereto. The upper and lower ends of the third separating disc 710 are respectively provided with a waste discharge port 730 and a third plating outlet 740. In this embodiment, the second plating screening mechanism 700 is disposed between the first plating outlet 140 and the first plating screening mechanism 500, and the receiving disc 510 is disposed below the third plating outlet 740.

[0090] Preferably, the fifth vibrator 720 is positioned below the third separation disc 710. In this embodiment, during the vibration of the third separation disc 710 driven by the fifth vibrator 720, intact spherical plating products roll down to the third plating product discharge port 740 below due to gravity. Meanwhile, defective plating products, because they are not perfectly spherical, are gradually moved upwards to the defective product discharge port 730 during vibration due to friction with the third separation disc 710, thereby achieving the separation of defective plating products.

[0091] Preferably, the third separation disc 710 is also triangular in shape, with the waste discharge port 730, the third plating outlet 740, and the position below the corresponding first plating outlet 140 located at the three corners of the triangle.

[0092] For MLCCs or coated products of different sizes and weights, the tilt angle of the separation disc may need to be set differently during separation. In some scenarios where the support surface is uneven, the tilt angle of the separation disc may also need to be adjusted in real time.

[0093] Therefore, one or more of the first material distribution mechanism 100, the second material distribution mechanism 600, and the second plating product screening mechanism 700 are provided with an inclination adjustment mechanism; the inclination adjustment mechanism is set on the frame 900 and connected to one of the first vibrator 120, the fourth vibrator 620, and the fifth vibrator 720, and is used to adjust the inclination of the first vibrator 120, the fourth vibrator 620, or the fifth vibrator 720, thereby adjusting the inclination of the first separation plate 110, the second separation plate 610, or the third separation plate 710.

[0094] In one specific embodiment, such as Figure 1 , Figure 2 , Figure 13 and Figure 14 As shown, the first material distribution mechanism 100 is provided with a first tilt adjustment mechanism 150, the second material distribution mechanism 600 is provided with a second tilt adjustment mechanism 650, and the second plating product screening mechanism 700 is provided with a third tilt adjustment mechanism 750.

[0095] Preferably, the tilt adjustment mechanisms described above are the same. The specific structure of the first tilt adjustment mechanism 150 is described below only by way of example.

[0096] like Figures 1 to 5 As shown, the first tilt adjustment mechanism 150 includes an adjustment plate 151, a mounting base 152, a guide plate 153, an adjustment shaft 154, and a lifting adjustment assembly 155; the mounting base 152 is mounted on the frame 900, and the adjustment plate 151 is used to mount the first vibrator 120. Specifically, the first vibrator 120 is mounted above the adjustment plate 151.

[0097] The guide plate 153 and the lifting adjustment assembly 155 are mounted on the mounting base 152. The adjusting shaft 154 is horizontally positioned, with one end connected to the adjusting support plate 151 and the other end passing through the adjusting hole provided on the guide plate 153. Preferably, the adjusting hole has an internal thread, and the adjusting shaft 154 has an external thread. In other embodiments, one end of the adjusting shaft 154 is connected to the guide plate 153, and the other end passes through the adjusting hole provided on the adjusting support plate 151.

[0098] The lifting and adjusting assembly 155 is connected to the adjusting tray 151. The lifting and adjusting assembly 155, through its lifting and lowering action, drives the adjusting tray 151 to rotate around the adjusting shaft 154, thereby driving the first vibrator 120 to rotate. The first vibrator 120 then drives the first separating disc 110 to rotate around the adjusting shaft 154, thus adjusting the tilt angle of the first separating disc 110. In this embodiment, the rotation direction of the adjusting shaft 154 is the same as the tilt direction of the first separating disc 110, thereby adjusting the height difference between the first product outlet 130 and the first plating residue outlet 140 of the first separating disc 110.

[0099] To achieve guidance during adjustment and stability of the first vibrator 120 during the adjustment process, in a preferred embodiment, such as Figure 2 and Figure 3 As shown, the adjusting plate 151 is provided with a first guide shaft 1511 and a second guide shaft 1512 on both sides of the adjusting shaft 154 in the rotation direction. The guide plate 153 is provided with a first arc-shaped hole 1531 corresponding to the sliding direction of the first guide shaft 1511, and a second arc-shaped hole 1532 corresponding to the sliding direction of the second guide shaft 1512. In this embodiment, when the lifting and adjusting assembly 155 rotates the adjusting plate 151, the first guide shaft 1511 is limited to move within the first arc-shaped hole 1531, and the second guide shaft 1512 is limited to move within the second arc-shaped hole 1532, making the adjusting plate 151 more stable during the adjustment process.

[0100] Preferred, such as Figure 2 and Figure 3 As shown, the guide plate 153 includes two parallel ones, which are arranged on both sides of the adjusting plate 151. In this embodiment, the adjusting shaft 154, the first guide shaft 1511, the second guide shaft 1512, the first arc-shaped hole 1531 and the second arc-shaped hole 1532 all include two symmetrically arranged ones.

[0101] In one specific embodiment, such as Figure 4 and Figure 5 As shown, the lifting adjustment assembly 155 includes a fixed base 1551, a connecting base 1552, a first connecting rod 1553, a second connecting rod 1554, a third connecting rod 1555, a fourth connecting rod 1556, a first adjusting block 1557, a second adjusting block 1558, and an adjusting rod 1559.

[0102] The fixed seat 1551 is disposed on the mounting base 152, and the connecting seat 1552 is disposed opposite to the bottom of the adjusting plate 153; the first ends of the first connecting rod 1553 and the second connecting rod 1554 are hinged to the fixed seat 1551, and the first ends of the third connecting rod 1555 and the fourth connecting rod 1556 are hinged to the connecting seat 1552; the second ends of the first connecting rod 1553 and the second ends of the third connecting rod 1555 are hinged to the first adjusting block 1557, and the second ends of the second connecting rod 1554 and the second ends of the fourth connecting rod 1556 are hinged to the second adjusting block 1558.

[0103] The first adjusting block 1557 and the second adjusting block 1558 each have internal threaded holes with opposite thread directions. The adjusting rod 1559 has external threads and passes through the internal threaded holes of the first adjusting block 1557 and the second adjusting block 1558. In this embodiment, by turning the adjusting rod 1559, the first adjusting block 1557 and the second adjusting block 1558 can be moved closer or further apart, thereby adjusting the height of the connecting seat 1552 and thus adjusting the height of one side of the adjusting plate 151.

[0104] In this embodiment, the rotation axes of the first ends of the first link 1553 and the second link 1554, which are hinged to the fixed seat 1551, can be on the same straight line or separate; the rotation axes of the first ends of the third link 1555 and the fourth link 1556, which are hinged to the connecting seat 1552, can be on the same straight line or separate.

[0105] In the above embodiments, the tilt adjustment mechanism enables adjustment of the vertical tilt of the separation disc. When the mounting surface is uneven, to achieve fine adjustment of the horizontal tilt of the separation disc, preferably, as follows: Figure 1 As shown, the mounting base includes a mounting plate 1521 and a first mounting seat 1522 and a second mounting seat 1523 located on both sides of the mounting plate 1521 along the inclined direction of the first separation disc 110.

[0106] The first mounting base 1522 and the second mounting base 1523 are respectively provided with multiple sets of vertical strip holes 1524 in parallel; the mounting plate 1521 is provided with a mounting hole 1525 corresponding to each strip hole 1524. The horizontal width of the strip hole 1524 is greater than the diameter of the mounting hole 1525. Preferably, the mounting hole 1525 is a threaded hole, which can be used to fix the mounting plate 1521 and the first mounting base 1522 and the second mounting base 1523 by passing a screw through the strip hole 1524 and engaging with the mounting hole 1525.

[0107] In this embodiment, without affecting the installation, the tilt of the mounting plate 1521 along the left and right sides of the first separation disc 110 can be appropriately adjusted, thereby adjusting the tilt of the left and right sides of the first tilt adjustment mechanism 150 as a whole, and thus adjusting the tilt of the left and right sides of the first separation disc 110. Similarly, the tilt of the left and right sides of the second separation disc 610 and the third separation disc 710 can also be adjusted.

[0108] To achieve the classified collection of plating products of more sizes, in a preferred embodiment, such as Figures 10-12 As shown, a second plating screen plate 532 is provided above the second plating collection area 512, and the aperture of the screen hole on the first plating screen plate 531 is smaller than the aperture of the screen plate on the second plating screen plate 532.

[0109] Preferred, such as Figures 10-12 As shown, a partition 540 is provided on the receiving tray 510. The first plating screen plate 531 and the second plating screen plate 532 are sequentially arranged on the partition 540. Above the partition 540, a second pressure frame 560 is provided. The second pressure frame 560 is used to fix the first plating screen plate 531 and the second plating screen plate 532 on the partition 540. Preferably, the second pressure frame 560 also has a certain height. It fixes the first plating screen plate 531 and the second plating screen plate 532 from the periphery and between the two. It can also prevent the plating product from falling from the left and right sides of the first plating screen plate 531 and the second plating screen plate 532.

[0110] In optional embodiments, such as Figures 10-12 As shown, a third plating sample collection area 550 is provided at the end of the partition 540. This third plating sample collection area 550 is used to collect plating samples that did not leak from the first plating sample screen plate 531 and the second plating sample screen plate 532. In this embodiment, the third plating sample collection area 550 can have an independent collection function, for example, it can be a drawer type, or it can be... Figure 12 It is shown to have a discharge port.

[0111] Preferred, such as Figure 12 As shown, the bottom surface of the first plating collection area 511 is inclined downward along the forward direction of the plating, and its end is provided with a fourth plating outlet 513. The bottom surface of the second plating collection area 512 is inclined downward along the forward direction of the plating, and its end is provided with a fifth plating outlet 514.

[0112] In this embodiment, the plating products discharged from the third plating product outlet 740 fall onto the receiving tray 510 of the first plating product screening mechanism 500. Driven by the vibration of the third vibrator 520, the plating products move forward on the receiving tray 510. As the plating products pass through the first plating product screen plate 531, smaller plating products fall through the screen holes into the lower first plating product collection area 511, while larger plating products move forward to the top of the second plating product screen plate 532 and fall into the lower second plating product collection area 511. Even larger plating products move to the third plating product collection area 550 at the end of the partition 540, thereby completing the classification and collection of more plating products of different sizes.

[0113] In an optional embodiment, for better collection of the plating materials, such as Figure 10 and Figure 11 As shown, the first plating product screening mechanism 500 also includes a first hopper 580 and a separation buffer plate 590 located below the first hopper 580 and disposed on the partition plate 540. The first hopper 580 is disposed below the third plating product discharge port 740, and the separation buffer plate 590 is disposed below the first hopper 580 and above the receiving tray 510.

[0114] In this embodiment, the separation buffer plate 590 is provided with a material collection area 591 directly below the discharge port of the first hopper 580, and multiple plating channels 592 distributed in a fan shape from the material collection area 591. The plating channels 591 extend to the side of the first plating screen 531 plate away from the second plating screen 532.

[0115] In this embodiment, after the plating material falls from the third plating material outlet 740, it is collected by the first hopper 580 and falls into the collection area 591. From the collection area 591, it flows evenly in a fan shape from multiple plating material channels 592 onto the first plating material screen plate 531, thereby avoiding local accumulation of plating material on the first plating material screen plate 531, improving the collection efficiency of plating material, and improving the accuracy of plating material classification and collection.

[0116] In a preferred embodiment, such as Figure 6 and Figure 7 As shown, the sieve plate 210 of the first product screening mechanism 200 includes a support plate 211 and a plurality of steel bars 212 extending along the MLCC's forward direction and disposed above the support plate 211. Strip-shaped holes for MLCCs to fall into are formed between the steel bars 212. A waste discharge trough 220 is provided at the end of each steel bar 212 on the support plate 211. The extending direction of the steel bars 212 is the same as the forward direction of the MLCC. Optionally, a steel bar placement groove is provided on the support plate 211, and the steel bars 212 are placed directly on the steel bar placement groove.

[0117] Optionally, a first pressure frame 213 is also provided on the support plate 211. The first pressure frame 213 is used to limit the position of the steel strip 212 on the periphery and prevent the MLCC from falling off on the left and right sides of the steel strip.

[0118] In an optional embodiment, to achieve buffering of MLCC receiving, such as Figure 9 As shown, a buffer 410 is provided inside the receiving box 400, and multiple inclined plates are alternately arranged below the discharge chute 330 inside the buffer 410. Alternatively, only one inclined plate can be used, the specific arrangement depending on the height of the receiving box 400.

[0119] exist Figure 9 In one embodiment, the inclined plate includes two plates: a first inclined plate 411a disposed directly below the discharge trough 330 to buffer the MLCCs directly, and a second inclined plate 411b disposed below the first inclined plate 411a to buffer the MLCCs falling from the first inclined plate 411a. The second inclined plate 411b is preferably configured to be inclined to the left and right respectively to divert the MLCCs.

[0120] Preferred, such as Figure 9 As shown, the shape of the buffer 410 is adapted to the receiving box 400, and it can be placed inside the receiving box 400. After the MLCCs are collected, they can be removed from the receiving box 400.

[0121] Preferred, such as Figure 6 and Figure 8 As shown, the vibrating plate 310 of the second product screening mechanism 300 is disc-shaped, and a vibrating base 340 is provided below it. The vibrating base 340 drives the vibrating plate 310 to vibrate in a ring. The lower part of the product screen plate 320 is preferably set as a conical surface 350, the outer periphery of the conical surface 350 is lower than its center, and the discharge chute 330 is connected to the outer periphery of the conical surface 350.

[0122] In this embodiment, after the MLCCs fall from the guide plate 230 onto the product screen plate 320 on the vibrating plate 310, the vibrating base 340 drives the vibrating plate 310 to vibrate in a ring, causing the MLCCs to disperse in a ring on the product screen plate 320. During this process, normal MLCCs fall from the through holes on the product screen plate 320 to the bottom conical surface 350, and slide from the bottom conical surface 350 to the discharge chute 330, thereby falling from the discharge chute 330 into the receiving box 400.

[0123] In one specific embodiment, such as Figure 1 and Figure 2As shown, the sorting machine 1000 for MLCC sorting also includes a feeding mechanism 800, which includes a feeding hopper 810 and a feeder 820 located below the feeding hopper 810. The end of the feeder 820 extends above the first separating disc 110.

[0124] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0125] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims, and the specification can be used to interpret the content of the claims.
