Description

Technical Field

[0001] This application relates to the field of molding equipment technology, specifically to a sheet receiving mechanism. Background Technology

[0002] Chip molding machines are key equipment in semiconductor packaging, such as lead frame (die) packaging. They encapsulate and protect the integrated circuit core by introducing and curing packaging materials (such as epoxy resin), ensuring stable chip operation in complex environments. After molding the die, the finished die needs to be unloaded and stored.

[0003] like Figure 1 As shown, the existing receiving mechanism uses the lifting component 02 to drive the material box close to the clamping mechanism 01, so that the clamping mechanism 01 can place the picked-up material pieces into the material box 03 in sequence. However, each time the clamping mechanism 01 places a material piece, the lifting component 02 needs to lift the material box 03, so that the clamping mechanism 01 can move the material box 03 to place the material piece. Then, the lifting component 02 drives the material box 03 to descend and reset, completing one placement. The steps are cumbersome, which will greatly affect the work efficiency and reduce the material piece storage efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a sheet receiving mechanism. By installing a liftable receiving plate inside the material box, the sheet can be placed into the material box without moving the box, greatly improving placement efficiency. The technical solution is as follows:

[0005] The sheet receiving mechanism includes a placement frame and a lifting module. The placement frame has a placement area for placing the sheet box.

[0006] A receiving plate located between the placement rack and the material box is used to receive material sheets;

[0007] The lifting module can drive the receiving plate to extend into or retract from the material box.

[0008] Preferably, the material box includes at least one receiving cavity for placing the material sheet; the bottom end of the material box is provided with a notch communicating with the receiving cavity for the receiving plate to extend into the receiving cavity.

[0009] Preferably, the lifting module includes a movable plate, a lead screw assembly, and a top rod. One end of the top rod is connected to the movable plate, and the other end extends out of the placement frame and connects to the receiving plate. The lead screw assembly is used to drive the movable plate to reciprocate.

[0010] Preferably, the lifting module is located at the bottom of the placement frame, and the bottom of the placement frame is provided with a mounting bracket to support the lifting module.

[0011] Preferably, it further includes a limiting structure, which is connected to the placement frame and is used to fix the material box within the placement area.

[0012] More preferably, the limiting structure includes a support block, a slide rod, and a locking plate. The slide rod is slidably connected to the support block, and the locking plate is disposed at one end of the slide rod for abutting and limiting the material box. An elastic connection is provided between the slide rod and the support block.

[0013] Preferably, the placement rack includes a base plate and a surrounding plate, as well as a support rod connecting the base plate and the surrounding plate.

[0014] Preferably, the placement rack is further provided with a slider for placing the material box, and the slider is provided with a slide rail for the material box to slide.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This application uses a lifting module to drive a receiving plate that can extend into the top opening of the material box to receive the material sheet. After each material sheet is received, the lifting module drives the receiving plate to descend by one material plate height. Therefore, the lifting module does not need to move back and forth every time it receives a material sheet, which can effectively improve work efficiency and help reduce energy consumption and lower costs.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] See Figures 2 to 4 To further elaborate on this application:

[0031] Combination Figure 2 The material receiving mechanism, used in conjunction with the clamping mechanism 01 to collect the material sheets, includes a placement frame 10 and a lifting module 40. The placement frame 10 has a placement area 100 for placing the material box 30; wherein, the front end and top end of the placement frame 10 are open to form the placement area 100. The material box 30 can be placed into the placement area 100 through the front end of the placement frame 10.

[0032] Combination Figure 4 A receiving plate 60 is located between the placement rack 10 and the material box 30; wherein, the bottom of the material box 30 is provided with a notch 310, and when the material box 30 is placed in the placement area 100, the notch 310 corresponds to the receiving plate 60.

[0033] The lifting module 40 can drive the receiving plate 60 to extend into or retract from the material box 30. By driving the receiving plate 60 into the top opening of the material box 30 through the lifting module 40, it can receive the material sheet. After each material sheet is received, the lifting module 40 drives the receiving plate to descend by one material plate height. This eliminates the need for the lifting module 40 to move back and forth every time a material sheet is received, thus effectively improving work efficiency and helping to reduce energy consumption and costs.

[0034] like Figure 3 As shown, in the initial state or when the material box 30 is full of material sheets, the receiving plate 60 is located between the placement rack 10 and the material box 30, so that the material box 30 can be removed from the placement area 100 and replaced with a new material box 30. When the material box 30 is full of material sheets, the receiving plate also returns to the initial state position accordingly.

[0035] like Figure 4As shown, during operation, the lifting module 40 drives the receiving plate 60 to extend into the top opening of the material box 30 to receive the material pieces. Each time the receiving plate 60 receives a material piece, the lifting module 40 drives the receiving plate 60 to descend a certain distance (which can be the height of one material piece) until the material box 30 is filled with material pieces. At the same time, the lifting module 40 moves the receiving plate 60 to the initial state position mentioned above.

[0036] The material box 30 includes at least one receiving cavity 300 for placing material sheets; in this embodiment, there are two receiving cavities 300 to accommodate more material sheets; there are also two receiving plates 60, and the driving module 40 can drive the receiving plates 60 to move synchronously. The notch 310 at the bottom of the material box 30 communicates with the receiving cavity 300, allowing the lifting module 40 to drive the receiving plate 60 to extend into the receiving cavity 300.

[0037] The receiving cavity 300 is equipped with a movable baffle 70, which supports the material sheet. When the material box 30 is full, the baffle 70 can cover the notch 310. The receiving plate 60 can push the baffle 70 up and down within the receiving cavity 300 to receive the material sheet, thus preventing the material sheet in the material box 30 from deforming or falling out at the notch 310.

[0038] In this embodiment, the lifting module 40 includes a movable plate 430, a lead screw assembly 410, and several push rods 420. One end of each push rod 420 is connected to the movable plate 430, and the other end extends out of the placement frame 10 and connects to the receiving plate 60. The lead screw assembly 410 is used to drive the movable plate 430 to reciprocate. The lead screw assembly 410 includes a lead screw and a nut, as well as a motor that drives the lead screw to rotate. The movable plate 430 is connected to the nut. In other embodiments, the lifting module 40 may also be a cylinder or other reciprocating drive mechanism.

[0039] The lifting module 40 is located at the bottom of the placement frame 10, and the bottom of the placement frame 10 is provided with a mounting frame 20 to support the lifting module 40. The mounting frame 20 includes a support plate 210 and a connecting plate 220 connecting the support plate 210 and the placement frame 10. The lead screw assembly 410 rotatably connects the placement frame 10 and the support plate.

[0040] To prevent the material box 30 from shifting within the placement area 100, the placement rack 10 is also provided with a limiting structure 50, which is used to fix the material box 30 within the placement area 100. By restricting the material box 30 from the front opening side of the placement rack 10, the material box 30 is prevented from shifting within the placement area 100.

[0041] The limiting structure 50 includes a support block 510 disposed on one side of the placement area 100. A slide rod 520 is slidably connected to the support block 510. One end of the slide rod 520 is provided with a retaining plate 530, which is located near the front end of the placement rack 10. The retaining plate 530 is used to abut against and limit the material box 30. The slide rod 520 and the support block 510 are elastically connected. Specifically, an elastic component 540, which can be a spring, can be provided between the slide rod 520 and the support block 510. The spring connects the support block 510 and the slide rod 520, thereby causing the retaining plate 530 to press the material box 30.

[0042] In this embodiment, the placement rack 10 includes a base plate 110 and a surrounding plate 120, as well as a support rod 130 connecting the base plate 110 and the surrounding plate 120. The surrounding plate 120 is U-shaped to restrict the position of the material box 30. The placement rack 10 also includes a slider 80 for placing the material box 30; the slider 80 is located on the top of the base plate 110 and supports the material box 30 at a certain height to accommodate the receiving plate 60, allowing the receiving plate 60 to be moved out of the material box 30 and preventing the receiving plate 60 from interfering with the removal of the material box 30; the slider 80 has a sliding track for the material box 30 to slide, facilitating its removal or placement.
