[0043] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0044] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0045] In the description of the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0047] In the description of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In the embodiments of the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] In the related art, before the shaping operation of the packaging frame, it is necessary to use a plastic sealing material to perform a plastic sealing operation on the flat packaging frame. The plastic sealing material is cylindrical and small in size before being heated. When performing the plastic sealing operation, it is necessary to manually divide and place a plurality of plastic sealing materials, and then put the arranged plastic sealing materials into the plastic sealing mold. In this way, the placement efficiency is low, and it is easy to miss or misplace. Compared with the prior art, the plastic sealing material dividing and placing device can realize automatic material division and placement, and the division and placement efficiency is high and the accuracy rate is high.

[0050] Figure 1 A schematic diagram of the structure of the molding compound feeding system provided in some embodiments of the present application.

[0051] like Figure 1 As shown, the plastic material feeding system includes: a feeding device 100, a reversing detection device 200 and a plastic material dividing and placing device 300. Among them, the feeding device 100 is used to provide plastic material; the reversing detection device 200 is arranged on one side of the feeding device 100, and is used to change the swing direction of the plastic material and determine whether the weight of the plastic material meets the standard; the plastic material dividing and placing device 300 is arranged on one side of the reversing detection device 200, and is used to divide and place the plastic material that meets the standard.

[0052] It is worth noting that the first direction corresponds to the X-axis of the spatial coordinate axis (i.e. the left-right direction), the second direction corresponds to the Y-axis of the spatial coordinate axis (i.e. the front-back direction), and the third direction corresponds to the Z-axis of the spatial coordinate axis (i.e. the up-down direction).

[0053] Figure 2 for Figure 1The structure schematic diagram of the feeding device 100 shown is at a certain angle.

[0054] like Figure 2 As shown, the feeding device 100 includes a support base 110, a hopper 120, a lifting mechanism 130 and a conveyor belt 140. The support base 110 is arranged on one side of the reversing detection device 200. The support base 110 has a notch. The lifting mechanism 130 is arranged on the support base 110 and extends into the hopper 120 for lifting the plastic packaging material in the hopper 120 to the notch. The conveyor belt 140 is arranged on the support base 110 and is connected to the notch.

[0055] Exemplarily, the material lifting mechanism 130 may include a material lifting cylinder 131 and a material lifting plate 132, wherein the material lifting cylinder 131 is disposed on the support seat 110, the material lifting plate 132 is connected to the output end of the material lifting cylinder 131, and the end of the material lifting plate 132 is inserted into the hopper 120. In this way, the material lifting plate 132 can lift the plastic packaging material in the hopper 120 to the position of the notch, so that the plastic packaging material can enter the conveyor belt 140 along the notch.

[0056] Exemplarily, the upper edge of the end of the lifting plate 132 is set as an inclined surface, so that an angle is formed between the upper edge of the end of the lifting plate 132 and the support seat 110. The plastic encapsulation material is cylindrical, and the height of the plastic encapsulation material is greater than the diameter of the plastic encapsulation material. When lifting the material, the inclined surface of the upper edge of the end of the lifting plate 132 is set, which is conducive to placing the plastic encapsulation material in a horizontal state between the lifting plate 132 and the support seat 110. If the plastic encapsulation material is initially placed on the lifting plate 132 in a vertical device, during the continuous rise of the lifting plate 132, since the upper edge of the end of the lifting plate 132 is set as an inclined surface, the plastic encapsulation material will have a tendency to turn from a vertical device to a horizontal state, so that it can eventually fall into the conveyor belt 140 in a horizontal state. In addition, when the plastic encapsulation material is loaded in a horizontal state, it will slide with the support seat 110, thereby reducing the friction between the plastic encapsulation material and the support seat 110 and reducing the loss of the plastic encapsulation material.

[0057] It is worth noting that, by setting the lifting mechanism 130 , the plastic packaging material can enter the conveyor belt 140 in a horizontal state, and at the same time, the plastic packaging material can enter the reversing detection device 200 in a horizontal state.

[0058] Figure 3 for Figure 1 The schematic diagram of the structure of the commutation detection device 200 shown in FIG. 2 is shown at a certain angle; Figure 4 for Figure 1 The structure diagram of the commutation detection device 200 shown in FIG. 2 is shown in another perspective.

[0059] like Figure 3 and Figure 4As shown, the reversing detection device 200 includes a base 210, a weighing mechanism 220, a rotating mechanism 230, a material moving mechanism 240 and a material pushing mechanism 250. The base 210 is provided with a feed seat 211, and the feed seat 211 is provided with a connected feed hole 212 and a through hole. The feed hole 212 is connected to the feeding device 100. The weighing mechanism 220 is arranged in the base 210. The rotating mechanism 230 includes a rotating seat 231 and a material blocking shell 232. The rotating seat 231 is rotatably arranged above the weighing mechanism 220. The rotating seat 2 A plurality of discharge cavities 2311 are provided at intervals along the outer circumference of 31, a material blocking shell 232 is provided on the rotating seat 231, a first pipe 2321 connected to the through hole is provided in the material blocking shell 232, a second pipe 2322 is provided in the material blocking shell 232 corresponding to the weighing mechanism 220, a material moving mechanism 240 is provided on one side of the feeding seat 211, and is used for transferring the plastic packaging material to the through hole, a material pushing mechanism 250 is provided on one side of the feeding seat 211 corresponding to the through hole, and is used for pushing in the plastic packaging material, so that the plastic packaging material passes through the first pipe 2321 and enters the discharge cavity 2311.

[0060] Exemplarily, the weighing mechanism 220 includes a weighing body and a material discharge fixture. The weighing body is disposed in the base 210 , and the material discharge fixture is disposed at the detection end of the weighing body and is located below the second pipe 2322 .

[0061] Exemplarily, the rotating mechanism 230 may include a rotating source, which is disposed on the base 210 and connected to the rotating base 231. Specifically, the rotating source may be a motor, a coupling, and a rotating shaft, which are not limited here.

[0062] Exemplarily, the material moving mechanism 240 may include a material moving cylinder 241 and a material moving block 242 . The material moving cylinder 241 is disposed on one side of the feed seat 211 . The material moving block 242 is connected to the material moving cylinder 241 . A material moving cavity is formed at the top of the material moving block 242 .

[0063] Exemplarily, the pushing mechanism 250 may include a pushing cylinder and a pushing post. The pushing cylinder is disposed on the feed seat 211 , and the pushing post is connected to the output end of the pushing cylinder so that the pushing post moves into the through hole.

[0064] When in use, the plastic encapsulating material enters the feed seat 211 through the feed hole 212 and is placed in the transfer cavity of the transfer block 242; the transfer cylinder 241 drives the transfer block 242 to move upward, so that the plastic encapsulating material is transferred to the side of the perforation; the pushing cylinder drives the pushing column to move, so that the pushing column pushes the plastic encapsulating material through the perforation and the first pipe 2321 into the discharge cavity 2311 of the rotating seat 231; then, the rotating seat 231 rotates in sequence, and each discharge cavity 2311 of the rotating seat 231 is placed with the plastic encapsulating material in sequence; when the plastic encapsulating material rotates to the position of the second pipe 2322, the plastic encapsulating material falls onto the discharge fixture through the second pipe 2322 and is weight tested; after the test is completed, it is grabbed by the transfer robot 311 of the transfer and separation mechanism 310 of the plastic encapsulating material dividing and placing device 300, and moved to the separation plate 312 for separation.

[0065] Figure 5 FIG. 2 is an exploded view of the rotating seat 231 and the material blocking shell 232; Figure 5 As shown, there are eight discharge chambers 2311. A gap is provided between the rotating seat 231 and the material blocking shell 232, so that the rotating seat 231 can rotate relative to the material blocking shell 232.

[0066] Figure 6 for Figure 1 The structure diagram of the plastic packaging material dividing and placing device 300 is shown at a certain angle.

[0067] like Figure 1 , Figure 6 As shown, a plastic packaging material dividing and placing device 300 includes: a transfer and separation mechanism 310, including a transfer robot 311 and a separation plate 312, the transfer robot 311 is arranged along a first direction, the separation plate 312 is located on one side of the transfer robot 311, and the separation plate 312 is provided with a plurality of separation holes 313 arranged at intervals; a swinging mechanism 320, including a movable seat 321, a swinging seat 322 and a material blocking component 323, the movable seat 321 is slidably arranged on one side of the separation plate 312, the movable seat 321 is configured to be able to slide along a second direction relative to the separation plate 312, the swinging seat 322 is slidably arranged on the movable seat 321, the swinging seat 322 is configured to be able to slide along the second direction relative to the movable seat 321, a plurality of swinging holes 3221 are arranged on the swinging seat 322, and the material blocking component 323 is arranged on the swinging seat 322, and the material blocking component 323 is configured to close the lower opening of the swinging hole 3221.

[0068] Exemplarily, there are ten separation holes 313 on the separation plate 312, of which five are in a group, and there are two groups in total. When in use, the swing holes 3221 on the swing seat 322 are aligned with the separation holes 313 in sequence, so that the plastic encapsulation material fills the swing holes 3221, so as to facilitate the subsequent plastic encapsulation material to be loaded into the lifting mechanism 330 at one time.

[0069] Exemplarily, the swing mechanism 320 may further include a first linear module and a second linear module, both of which are arranged along the second direction, the first linear module is connected to the moving seat 321, the second linear module is arranged on the moving seat 321, and the second linear module is connected to the swing seat 322. The first linear module and the second linear module are both cylinders.

[0070] Exemplarily, the first linear module is used to drive the movable seat 321 and the structure on the movable seat 321 to move between the ejecting mechanism 330 and the transfer and separation mechanism 310 .

[0071] Exemplarily, the second linear module is used to drive the swing seat 322 to move, thereby making the swing hole 3221 correspond to the separation hole 313 on the separation plate 312 .

[0072] like Figure 6 As shown, the swinging seat 322 includes a first long side portion 3222 and a second long side portion 3223. The first long side portion 3222 and the second long side portion 3223 are arranged at intervals, and a plurality of swinging holes 3221 are penetrated through the first long side portion 3222 and the second long side portion 3223. The number of the separation holes 313 is the same as the number of the swinging holes 3221 on the first long side portion 3222, and the number of the separation holes 313 is the same as the number of the swinging holes 3221 on the second long side portion 3223.

[0073] Exemplarily, the first long side 3222 and the second long side 3223 have the same length. Ten swing holes 3221 are provided on the first long side 3222. Ten swing holes 3221 are provided on the second long side 3223. The swing holes 3221 on the first long side 3222 and the swing holes 3221 on the second long side 3223 can correspond one-to-one to the separation holes 313 of the separation plate 312.

[0074] When in use, the second linear module drives the swinging seat 322 to move along the second direction, firstly moves the first long side 3222 to the right below the separation plate 312, so that the swinging holes 3221 of the first long side 3222 correspond to the separation holes 313 on the separation plate 312. At this time, the transfer robot 311 sequentially clamps the plastic packaging materials that meet the standards from the reversing detection device 200 and moves them to each separation hole 313, and sequentially puts the plastic packaging materials into each separation hole 313, and the plastic packaging materials fall into the swinging holes 3221 through the separation holes 313. When the swinging holes 3221 of the first long side 3222 are filled with plastic packaging materials, the second linear module drives the swinging seat 322 to move along the second direction, so that the second long side 3223 moves to the right below the separation plate 312, so that the swinging holes 3221 of the second long side 3223 correspond to the separation holes 313 on the separation plate 312. At this time, the transfer robot 311 sequentially clamps the plastic packaging materials that meet the standards from the reversing detection device 200 and moves them to each separation hole 313, and sequentially puts the plastic packaging materials into each separation hole 313, and the plastic packaging materials fall into the swing hole 3221 through the separation hole 313. When the swing hole 3221 of the second long side 3223 is slowed down, the first linear module drives the moving seat 321 to move toward the lifting mechanism 330, so that the moving seat 321 moves above the lifting mechanism 330.

[0075] like Figure 6 As shown, the swing seat 322 includes a middle portion 3224, and the middle portion 3224 is located between the first long side portion 3222 and the second long side portion 3223; the material blocking assembly 323 includes a first material blocking cylinder 3231, a first material blocking plate 3232, a second material blocking cylinder 3233 and a second material blocking plate 3234, the first material blocking cylinder 3231 and the second material blocking cylinder 3233 are both arranged on the middle portion 3224, the output end of the first material blocking cylinder 3231 and the output end of the second material blocking cylinder 3233 are arranged back to back, the first material blocking plate 3232 is connected to the output end of the first material blocking cylinder 3231, and the second material blocking plate 3234 is connected to the output end of the second material blocking cylinder 3233.

[0076] Exemplarily, the first material blocking cylinder 3231 drives the first material blocking plate 3232 to move, so that the first material blocking plate 3232 can move relative to the first long side 3222, so that the lower opening of the swing hole 3221 on the first long side 3222 can be opened and closed. When swinging, the first material blocking plate 3232 is located directly below the first long side 3222, and the plastic encapsulation material enters the swing hole 3221 through the separation hole 313 and is supported by the first material blocking plate 3232. When the plastic encapsulation material is transferred from the swing seat 322 to the ejecting mechanism 330, the first material blocking cylinder 3231 drives the first material blocking plate 3232 to move, so that the lower opening of the swing hole 3221 on the first long side 3222 is opened, and the plastic encapsulation material located in the swing hole 3221 can fall into the ejecting mechanism 330.

[0077] Since the working process and principle of the second material blocking cylinder 3233 and the second material blocking plate 3234 are the same as those of the first material blocking cylinder 3231 and the first material blocking plate 3232 , they will not be described herein in detail.

[0078] Figure 7 for Figure 6 The structure schematic diagram of the ejecting mechanism 330 shown at a certain angle.

[0079] like Figure 7 As shown, the device also includes a lifting mechanism 330, which includes a lifting seat 331, a transition swing plate 332, a lifting seat 333 and a lifting column 334. The lifting seat 331 is movably arranged on one side of the moving seat 321, and the lifting seat 331 is configured to be able to move along a third direction relative to the moving seat 321. The transition swing plate 332 is arranged on the lifting seat 331, and convex portions 3321 are arranged in parallel on the transition swing plate 332. The transition swing plate 332 is provided with a receiving hole 3322, and the receiving hole 3322 passes through the upper surface of the convex portion 3321 to the lower surface of the transition swing plate 332 along the third direction. The lifting seat 333 is movably arranged between the lifting seat 331 and the transition swing plate 332. The lifting column 334 is arranged on the lifting seat 333, and the end of the lifting column 334 is penetrated into the receiving hole 3322.

[0080] Exemplarily, the ejection mechanism 330 may further include a first cylinder and a second cylinder, both of which are arranged along the third direction. The output end of the first cylinder is connected to the lifting seat 331, the second cylinder is arranged on the lifting seat 331, and the output end of the second cylinder is connected to the ejection seat 333.

[0081] When in use, when the plate is swung, the swing seat 322 is located above the transition swing plate 332, and the material blocking component 323 opens the swing hole 3221, and the plastic packaging material in the swing hole 3221 of the swing seat 322 falls into the receiving hole 3322 of the transition swing plate 332, and the bottom of the plastic packaging material abuts against the end of the lifting column 334. Then the first cylinder drives the lifting seat 331 to rise, so that the lifting seat 331, the transition swing plate 332, the lifting seat 333 and the lifting column 334 rise synchronously; the second cylinder drives the lifting seat 333 to rise, so that the lifting column 334 pushes up the plastic packaging material and enters the next process.
