Description

Technical Field

[0001] This utility model relates to the field of clamping devices, and in particular to a wafer clamping device for wafer cleaning. Background Technology

[0002] A wafer is a silicon wafer used to fabricate silicon semiconductor circuits; its raw material is silicon. High-purity polycrystalline silicon is dissolved, doped with silicon crystal seeds, and then slowly pulled out to form cylindrical single-crystal silicon. After grinding, polishing, and slicing, the silicon ingot forms a silicon wafer. Domestic wafer production lines mainly use 8-inch and 12-inch wafers. The main wafer processing methods are wafer fabrication and batch processing, which involves processing one or more wafers simultaneously. As semiconductor feature sizes shrink and processing and measurement equipment becomes more advanced, new data characteristics have emerged in wafer processing. Simultaneously, the reduction in feature size increases the impact of airborne particles on the quality and reliability of the processed wafer, and with improved cleanliness, new data characteristics regarding particle count have also emerged.

[0003] Existing wafer clamps are simply clamps made of elastic steel sheets. Because the elastic steel sheets are elastic, they will open outwards. Therefore, when clamping a wafer, a person needs to use at least two fingers to press the clamp inwards from both sides of the clamp to hold the wafer. It is necessary to continuously press the left and right sides of the clamp to ensure that the clamp can continuously hold and fix the wafer. However, some people have strong hands and can easily press the clamp too much, damaging the wafer. Therefore, there is a need for a wafer clamp device for wafer cleaning that can increase the pressing resistance of the clamp to avoid excessive pressing and damage to the wafer. Utility Model Content

[0004] The purpose of this invention is to overcome the defect that the pressing resistance of the clamp cannot be adjusted and to provide a wafer clamp device for wafer cleaning.

[0005] The technical solution to achieve the above objective is: a wafer clamping device for wafer cleaning, including a clamping handle, two symmetrically distributed clamping plates connected to both ends of the open end of the clamping handle, the clamping handle and the clamping plates are both made of stainless steel sheets, a limiting mechanism is sleeved on the outside of the clamping handle, a supporting mechanism is installed on the limiting mechanism, an adjusting mechanism is installed on the supporting mechanism, and a protective mechanism is installed on the clamping plates.

[0006] The adjustment mechanism includes a connecting rod, a cross groove, a resistance rod, a resistance spring, and a screw. Both ends of the connecting rod are provided with cross grooves. A resistance rod is slidably connected in the cross groove. A resistance spring is connected to the side wall of the resistance rod. One end of the resistance spring is connected to one side wall of the cross groove. A screw is movably connected through the side wall of the connecting rod.

[0007] Preferably, a rubber pad is connected to the end of the resistance rod away from the connecting rod.

[0008] Preferably, the limiting mechanism includes a horizontal plate, a limiting screw hole, a sliding groove, and a limiting plate. The sidewalls of the two horizontal plates each have two symmetrically distributed sliding grooves. The two horizontal plates are staggered vertically. The horizontal plates have limiting screw holes. The sidewalls of the limiting plate are slidably connected to the sliding grooves.

[0009] Preferably, the sidewall of the limiting plate is fitted with a rubber sleeve.

[0010] Preferably, the support mechanism includes a support rod, a screw, and a mounting hole. The mounting hole is provided at the center of the side wall of the support rod, and a screw is connected to the end side wall of the support rod. The side wall of the mounting hole is provided with a mounting screw hole. The side wall of the screw is threadedly connected to the mounting screw hole, and the side wall of the screw is threadedly connected to the limiting screw hole.

[0011] Preferably, the protective mechanism includes a protective plate, slots, and a rubber rod. Two symmetrically distributed slots are provided on one side wall of the protective plate. One side wall of the protective plate is connected to one end of the rubber rod, and the other side wall of the protective plate is connected to the other end of the rubber rod.

[0012] Preferably, the protective plate is U-shaped.

[0013] Preferably, an elastic rope is connected to the side wall end of the clamp handle.

[0014] The beneficial effects of this utility model are:

[0015] 1) After fixing the connecting rod to the support mechanism, press the side wall of the clamp handle inward. The two side walls of the clamp handle will touch the resistance rod, and the resistance rod will press the resistance spring. The elastic force of the resistance spring will increase the resistance of pressing the clamp handle inward, thereby achieving the effect of adjusting the pressing resistance of the clamp handle. You can push the horizontal plate according to your own grip strength to adjust the distance between the adjustment mechanism and the two side walls of the clamp handle, that is, adjust the distance between the side wall of the clamp handle and the resistance rod to adjust the difficulty of the resistance rod obstructing the two side walls of the clamp handle.

[0016] 2) First, pass the clamp handle through the square frame composed of two horizontal plates and two limiting plates. Then, screw the screw into the limiting screw hole to fix the support rod between the two horizontal plates. The side wall of the support rod is parallel to the front side wall of the horizontal plate, so that the mounting hole faces the opening of the clamp handle. Insert the connecting rod into the mounting hole and screw the screw into the mounting screw hole to fix the connecting rod on the support rod. This achieves the effect of convenient installation and support adjustment mechanism. When the clamp handle is not in use, insert the clamp piece into the slot. Both clamp pieces on both sides can be inserted into the slot. The clamp piece is wrapped and protected by the protective plate. Utilizing the elasticity of the rubber rod itself, the rubber rod can be bent, which makes it easy to insert the clamp piece into the slot. Attached Figure Description

[0030] After fixing the connecting rod 501 to the support mechanism 4, press the side wall of the clamp handle 1 inward. The two side walls of the clamp handle 1 come into contact with the resistance rod 503. The resistance rod 503 presses the resistance spring 504. The elastic force of the resistance spring 504 is used to increase the resistance of pressing the clamp handle 1 inward, thereby achieving the effect of adjusting the pressing resistance of the clamp handle 1. According to one's own grip strength, the horizontal plate 301 can be pushed to adjust the distance between the adjustment mechanism 5 and the two side walls of the clamp handle 1, that is, to adjust the distance between the side wall of the clamp handle 1 and the resistance rod 503, thereby adjusting the difficulty of the resistance rod 503 in obstructing the two side walls of the clamp handle 1.

Both clips 2 on both sides can be inserted into the slot 602, so that the clips 2 are wrapped and protected by the protective plate 601. Utilizing the elasticity of the rubber rod 603 itself, the rubber rod 603 can be bent, which makes it easy to insert the clip 2 into the slot 602.
