DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] The utility model discloses a resin feeding mechanism, which drives all push plates to move together through a bottom plate so that the push plates cooperate with fixed plates to achieve feeding, greatly simplifies the structure of the feeding mechanism, reduces the volume of the feeding mechanism, and solves the problem of the existing feeding mechanism having a large overall volume.

[0025] like Figure 4 As shown, the resin feeding mechanism is disposed in the resin silo 500 , and a resin discharge mechanism 600 cooperating with the resin feeding mechanism is also disposed at the end of the resin silo 500 .

[0026] like Figure 1 The resin feeding mechanism shown in the figure includes: a power assembly 100, a base plate 200, a push plate 300 and a fixed plate 400, as shown in FIG. Figure 2 and 3 As shown, five push plates 300 and five fixing plates 400 are provided. The push plates 300 are directly mounted on the bottom plate 200 by screws, which greatly simplifies the structure, reduces the volume and the difficulty of installation.

[0027] The power assembly 100 and the fixing plate 400 are installed in the resin silo 500 , the push plate 300 is connected to the bottom plate 200 , the push plate 300 and / or the bottom plate 200 are connected to the power assembly 100 , and the push plate 300 and the fixing plate 400 are obliquely arranged in the resin silo 500 .

[0028] The push plates 300 and the fixed plates 400 are staggered and matched, and the top height positions of the plurality of fixed plates 400 and the push plates 300 are arranged in a stepped structure.

[0029] The power assembly 100 is used to drive the push plate 300 to perform reciprocating linear motion, wherein the power assembly 100 is a cylinder, or a hydraulic cylinder, or a combination of a screw mechanism and a motor, or a combination of a gear rack mechanism and a motor.

[0030] In this embodiment, if Figure 2 and 3 The bottom plate 200 shown is a stepped structure.

[0031] Or the bottom plate 200 is a flat plate arranged obliquely.

[0032] like Figure 2 and 3 At least one push plate 300 is installed on each step of the bottom plate 200, and three push plates 300 are provided on the steps with a wider width.

[0033] The stepped bottom plate 200 or the obliquely arranged bottom plate 200 can reduce the length of the push plate 300 and the cantilever length of the push plate 300 , thereby further ensuring working stability.

[0034] In this embodiment, if Figure 2The resin feeding mechanism shown includes: a first fixed plate 401, a first fixed plate 401 and a first push plate 301, the first push plate 301 is arranged between the first fixed plate 401 and the first fixed plate 401, and the top end height position of the first fixed plate 401 is smaller than the bottom end height position of the first fixed plate 401.

[0035] When the power assembly 100 drives the first push plate 301 to move to the lowest position, the top height position of the first push plate 301 is between the top height position of the first fixing plate 401 and the bottom height position of the first fixing plate 401 .

[0036] The top height of the first fixing plate 401 is smaller than the bottom height of the first fixing plate 401 , so that the push plate 300 between the first fixing plate 401 and the first fixing plate 401 is always secured between the two fixing plates 400 , further improving the working stability.

[0037] In this embodiment, the push plate 300 is clearance-matched with the adjacent fixing plate 400 .

[0038] Without adding any additional guide components, the distance between the fixing plates 400 can be used to limit the push plate 300 to ensure the position of the push plate 300, thereby improving the working stability.

[0039] In this embodiment, if Figure 1 The power assembly 100 shown includes: a cylinder 101 , a slide rail 102 and a slider 103 . The cylinder 101 and the slide rail 102 are installed on the resin silo 500 , the slider 103 is installed on the slide rail 102 , and the push plate 300 is connected to the slider 103 .

[0040] Working principle: The resin used for semiconductor packaging is generally a cylindrical structure. When the power assembly 100 drives the push plate 300 to move to the lowest position, the top height of the push plate 300 is less than or equal to the top height of the upper adjacent fixed plate 400. Figure 2 The top height of the push plate 300 is shown to be lower than the top height of the upper adjacent fixing plate 400, so that the resin on the upper fixing plate 400 falls onto the push plate 300 due to gravity.

[0041] When the power assembly 100 drives the push plate 300 to move to the highest position, the top height position of the push plate 300 is greater than or equal to the top height position of the next adjacent fixed plate 400. Figure 3 The top height position of the push plate 300 is shown to be greater than the top height position of the adjacent fixing plate 400 of the next stage, so that the resin on the push plate 300 falls on the push plate 300 due to gravity.

[0042] Repeat the above steps to move the resin in the resin silo 500 layer by layer to the top resin discharge mechanism 600 position, and fix all the push plates 300 together through the bottom plate 200. When the power component 100 drives the bottom plate 200 or one of the push plates 300 to move, all the push plates 300 move together and cooperate with all the fixed plates 400, which greatly simplifies the structure of the feeding mechanism. In addition, since the fixed plate 400 is always stationary, the drop rate of the resin at the top of the fixed plate 400 is reduced, thereby improving the resin feeding efficiency.

[0043] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
