Description

Technical Field

[0001] The utility model belongs to the technical field of bonding tooling, in particular to a manual bonding tooling. Background Art

[0002] Currently, the common bonding fixtures that come with bonding machines on the market are mainly used in semiconductor wafer processing and production. Their application scope is limited to laboratory development and application personnel. They can only clamp or bond small amounts of workpieces that move in a plane. Due to the single standard of wafer production, once mass production is carried out, high-efficiency automated production equipment is used instead of manual or semi-automatic bonding machines. Therefore, the bonding fixtures used in existing bonding machines have certain limitations in mass production. They use a parallel clamping method, which has defects such as unstable clamping and unchanged rotation and shifting operations.

[0003] The structure of the existing bonding tool is set as a U-shaped fixed base, and a threaded rod is connected to the internal thread of one side of the fixed base, and the two ends of the threaded rod are respectively connected to the handle and the movable plate. The movable movable plate and one side of the fixed base can fix the workpiece, but when the fixed workpiece needs to be aligned, it needs to be moved as a whole, which is inconvenient to operate. Since the shapes of the movable plate and the fixed base are set as flat, the contact between the movable plate and the fixed base has a poor fixing effect on the workpiece. Therefore, a bonding manual tool is needed to solve the above problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a manual bonding tool to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a manual bonding tool, comprising a chuck cover, a chuck body, a rotating base, a rotating handle, a bearing, a fixed base, and a connecting cover, wherein the chuck body comprises a chuck body, and the outer surface of the chuck body is provided with a plurality of first grooves and a plurality of second grooves, wherein the plurality of first grooves and the plurality of second grooves are arranged in a staggered manner;

[0006] The rotating base includes a rotating seat, a first threaded hole is formed on one side of the rotating seat, a second threaded hole is formed on the bottom of the rotating seat, the rotating handle is threadedly connected to the first threaded hole, and the bottom of the chuck body overlaps the bottom of the inner surface of the rotating seat;

[0007] The chuck pressure cover is threadedly connected to the outside of the rotating seat, the chuck body is overlapped in the chuck pressure cover and the rotating seat, the rotating seat is clamped in the bearing, the bearing is clamped in the fixed base, the connecting cover is threadedly connected in the second threaded hole, and the connecting cover is rotatably connected in the fixed base.

[0008] As a preferred solution, the contact portion between the chuck body and the chuck cover is wedge-shaped.

[0009] As a preferred solution, the outer surface of the chuck body located inside the rotating seat is designed to be wedge-shaped, and the bottom inside the rotating seat is designed to be wedge-shaped.

[0010] As a preferred solution, the height of the lower surface of the connecting cover is higher than the height of the lower surface of the fixed base.

[0011] As a preferred solution, the upper surface of the bearing overlaps with the rotating seat, and the lower surface of the bearing overlaps with the connecting cover.

[0012] As a preferred solution, the rotating portion of the connecting cover and the fixed base is configured to be stepped.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a high-precision chuck body and a rotating seat as a rotating structure, so that the tool can be flexibly and freely rotated, and the workpiece is clamped in the chuck body by the circular clamping hole in the chuck body as a whole, which makes the clamping more stable. Moreover, the tool only needs to rotate the chuck body easily to avoid the instability, time-consuming and inaccurate problems caused by the current operation method of moving the entire tool back and forth, which can meet the needs of batch, efficient, easy and convenient production of workpieces. Moreover, the tool only needs to reverse the chuck cover to release the clamping of the workpiece through the chuck body, which improves the convenience of workpiece clamping during the bonding process of the tool.

[0015] The utility model is provided with a chuck body, and because the chuck body is overlapped between the chuck pressure cover and the rotating seat, when it is necessary to clamp different workpieces, the chuck body can be replaced, thereby improving the adaptability of the tooling.

[0025] See also Figure 1-6 The utility model provides a manual bonding tool, including a chuck cover 1, a chuck body 2, a rotating base 3, a rotating handle 4, a bearing 5, a fixed base 6 and a connecting cover 7. The chuck body 2 includes a chuck body 201. The outer surface of the chuck body 201 is provided with a plurality of first grooves 202 and a plurality of second grooves 203. The plurality of first grooves 202 and the plurality of second grooves 203 are staggered.

A second threaded hole 303 is formed at the bottom of the rotating seat 301. The rotating handle 4 is threadedly connected to the first threaded hole 302. The bottom of the chuck body 201 overlaps the bottom of the inner surface of the rotating seat 301. The first threaded hole 302 is used to fix the rotating handle 4.

[0027] The chuck pressure cover 1 is threadedly connected to the outside of the rotating seat 301, the chuck body 201 is overlapped inside the chuck pressure cover 1 and the rotating seat 301, the height of the lower surface of the connecting cover 7 is higher than the height of the lower surface of the fixed base 6, the rotating portion of the connecting cover 7 and the fixed base 6 is set to be stepped, the rotating seat 301 is clamped in the bearing 5, the bearing 5 is clamped in the fixed base 6, the upper surface of the bearing 5 overlaps with the rotating seat 301, and the lower surface of the bearing 5 overlaps with the connecting cover 7, the connecting cover 7 is threadedly connected in the second threaded hole 303, and the connecting cover 7 is rotatably connected to the fixed base 6. By setting the second threaded hole 303, the second threaded hole 303 is used to fix the connecting cover 7;
