Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor production equipment, and in particular relates to a chip glue coating and pressing mechanism. Background Art

[0002] In the semiconductor industry, during the chip production process, in order to provide a certain degree of protection, the outer edges of the chips need to be coated with glue.

[0003] At present, the gluing operation of chips is basically done manually. The chip is adsorbed and fixed, and after the glue barrel is manually held and aligned, the chip is rotated for manual gluing. However, this gluing method can only be performed one chip at a time, resulting in low gluing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a chip glue coating and pressing mechanism for solving the problem of low chip glue coating efficiency.

[0005] The utility model solves the above technical problems with the following technical solutions: a chip glue coating and pressing mechanism, which comprises:

[0006] frame;

[0007] A base, mounted on the bottom edge of the frame, and used for placing a chip;

[0009] The clamping assembly is screwed on the top edge of the frame, and the output end of the clamping assembly abuts against the uppermost spacer.

[0010] Compared with the prior art, the above technical solution has the following beneficial effects:

[0011] By installing the base on the frame and the clamping assembly on the top of the frame, the stack of chips on the base in the frame can be compressed. The spacers separate the chips to expose the edges for gluing. At the same time, the first groove in the spacer facilitates the matching and positioning of the chips, so that a stack of chips can remain concentric, which is convenient for subsequent unified gluing operations.

[0012] Based on the above technical solution, the embodiment of the present application can also be improved as follows:

[0013] Furthermore, a second groove corresponding to the first groove is formed on the base for matching and placing the chip.

[0014] Furthermore, a plurality of the chips are arranged coaxially with the first groove and the second groove.

[0015] Furthermore, the pressing assembly comprises:

[0016] A clamping shaft, threadedly connected to the top edge of the frame, the clamping shaft and the base being coaxially arranged;

[0017] A gland connected to the first end of the clamping shaft;

[0018] A hand wheel is mounted on the second end of the clamping shaft.

[0019] Furthermore, the pressure cover is movably connected to the first end of the clamping shaft.

[0020] Furthermore, a widened portion is formed on the bottom edge of the frame.

[0021] Furthermore, at least one positioning groove is provided on the outer periphery of the spacer. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example

[0040] like Figure 1-3 As shown, the chip glue coating and pressing mechanism provided by the utility model comprises: a frame, a base, a plurality of spacers and a pressing assembly.

[0041] The frame is a rectangular frame, and the base is installed on the bottom edge of the frame. The base is used to place the chip. Both sides of the spacer are provided with a first groove matching the chip. The first groove is opened at the center of the spacer. Every two spacers are clamped on both sides of the chip through the first groove. The spacers and the chips are alternately stacked on the base, and the chips are stacked concentrically in a stack through the first grooves on the spacers.

[0042] The pressing assembly is screwed onto the top edge of the frame, and the output end of the pressing assembly abuts against the topmost spacer to press the stacked multiple spacers and chips.

[0043] By installing the base on the frame and the clamping assembly on the top of the frame, the stack of chips on the base in the frame can be compressed. The spacers separate the chips to expose the edges for gluing. At the same time, the first groove in the spacer facilitates the matching and positioning of the chips, so that a stack of chips can remain concentric, which is convenient for subsequent unified gluing operations.

[0044] Specifically, a second groove corresponding to the first groove is opened on the base for matching and placing the chip. The diameters of the first groove and the second groove are set to be consistent, so that the bottom chip can be just placed in the second groove, and then the upper chip is matched and accommodated in the first groove of the spacer.

[0045] In this embodiment, several chips are arranged coaxially with the first groove and the second groove. In this way, through the second groove on the base and the first groove on the spacer, multiple chips can be stacked while ensuring that they are arranged concentrically from top to bottom, so that when glue is applied subsequently, the glue applied on each chip can be kept consistent and the glue application can be uniform.

[0046] In this embodiment, the clamping assembly includes: a clamping shaft, a pressure cover and a hand wheel.

[0047] The clamping shaft is threadedly connected to the top edge of the frame, and the clamping shaft is coaxially arranged with the base to ensure that when the clamping shaft rotates and retracts, its bottom can be aligned with the center of the stacked spacers. The pressure cover is connected to the first end of the clamping shaft, and the hand wheel is installed on the second end of the clamping shaft. When in use, the hand wheel is manually turned to drive the clamping shaft up and down to achieve clamping or loosening.

[0048] Specifically, the pressure cover is movably connected to the first end of the pressing shaft, so that when pressing and releasing, the pressure cover is prevented from rubbing against the top of the spacer due to rotation.

[0049] In this embodiment, a widened portion is formed at the bottom edge of the frame, so that the stability of the frame when placed on a workbench or the like can be improved.

[0050] In order to further improve the concentricity effect after each spacer is placed, at least one positioning groove is opened on the outer periphery of the spacer. After the spacers are connected to the chips sandwiched in the middle and stacked, they can be positioned through the positioning grooves on the outer periphery of the spacers, so that the stacked spacers maintain good concentricity. During this process, the hand wheel can be rotated to tighten the top spacer.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
