Description

Technical Field

[0001] This utility model relates to the field of semiconductor cutting technology, specifically a semiconductor cutting fixing device. Background Technology

[0002] Crystal rod cutting refers to removing the small-diameter head and tail parts of the crystal rod after it has been trimmed and ground, and then cutting the crystal rod into thin slices. Because silicon is very hard, in this process, a ring-shaped thin saw blade with diamond particles embedded in its inner diameter edge is used to cut the crystal rod. The position of the crystal rod needs to be restricted during the cutting process.

[0003] A relevant reference is Chinese utility model patent CN209344040U, which discloses a fixing device for semiconductor processing, including a processing table. A partition is welded to the inner wall of the processing table. A driving device is located at the center of the bottom of the processing table. A connecting device is located at the bottom of the partition. Limiting devices are located on both sides of the connecting device. A clamping device is located at the top of the partition. Support legs are fixedly connected to both sides of the bottom of the processing table. This utility model, through the arrangement of the partition, driving device, connecting device, limiting device, and clamping device, enables the semiconductor processing fixing device to have the advantage of good positioning effect. At the same time, it solves the problem of poor positioning effect in existing semiconductor processing fixing devices, which makes the workpiece prone to displacement under external force during semiconductor processing, resulting in low processing efficiency, serious workpiece scrapping, and increased production costs.

[0004] Because the overall length of the crystal rod will shorten during cutting, in order to ensure the fixing effect of the crystal rod and resist the stress generated during cutting, most of the crystal rod needs to be located inside the fixing device, with only the area near the cutting point exposed. During use, it is impossible to adjust the position of the crystal rod in real time. It is very inconvenient to constantly adjust the position of the crystal rod during cutting, and the cutting operation needs to be stopped when adjusting the position, which affects the cutting efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a semiconductor cutting and fixing device, comprising: a base plate, a controller fixedly mounted on the top of the base plate, a slide rail fixedly mounted on the top of the base plate, a support column fixedly mounted at the rear end of the base plate, an auxiliary piston inserted into the upper end of the support column, a tray fixedly mounted at the front end of the auxiliary piston, a fixing frame fixedly mounted on the top of the base plate, connecting pistons fixedly mounted at the four corners of the fixing frame, a movable frame fixedly mounted at the rear end of the connecting piston, a limiting block fixedly mounted inside the fixing frame and the movable frame, a movable block movably mounted inside the limiting block, a limiting piston fixedly mounted at the upper end of the movable block, a connecting block movably mounted at the end of the limiting piston, a connecting plate fixedly mounted on one side of the connecting block, and a rubber pad fixedly mounted on one side of the connecting plate; the slide rail facilitates the movement of the movable frame.

[0009] As a preferred technical solution of this utility model, the front end of the base plate is provided with a protrusion structure with the same height as the thickness of the slide rail. The slide rail is symmetrically installed on the top of the base plate with the center of the base plate as the reference. The support column is symmetrically installed on the top of the base plate with the center of the auxiliary piston as the reference. The controller can easily coordinate the elongation of the auxiliary piston, the connecting piston, and the limiting piston.

[0010] As a preferred technical solution of this utility model, the tray is movably connected to the base plate through an auxiliary piston, the front end of the tray is provided with a conical recessed structure, and the tray is made of rubber; the tray can fit into the conical structure of the crystal rod, thereby protecting the crystal rod.

[0011] As a preferred embodiment of this utility model, the fixed frame is fixedly installed above the protruding structure at the front end of the base plate, and the movable frame is movably connected to the fixed frame through a connecting piston. The bottom end of the movable frame is fixedly connected to the slider of the slide rail. The connecting piston can adjust the position of the movable frame.

[0012] As a preferred technical solution of this utility model, the movable frame is slidably connected to the base plate through a slide rail, and the limiting block is symmetrically installed on the inner side of the four corners of the fixed frame and the movable frame with the center of the fixed frame and the movable frame as the reference; the fixed frame and the movable frame can limit the position of the limiting block.

[0013] As a preferred embodiment of this utility model, the movable blocks are symmetrically installed on the upper and lower sides of the limiting block, and the movable blocks and the limiting blocks are rotatably connected. The limiting piston is installed at the ends of the movable blocks on the upper and lower sides of the limiting block. The movable blocks facilitate the rotation of the limiting piston.

[0014] As a preferred technical solution of this utility model, a movable block is also fixedly installed at the end of the limiting piston, and the movable block at the end of the limiting piston and the connecting block form a rotatable connection. The connecting block is symmetrically installed at the upper and lower ends of the connecting plate, and the connecting blocks at the upper and lower ends of the connecting plate are respectively connected to the movable blocks at the ends of the limiting pistons on the upper and lower sides. One side of the rubber pad has an arc surface structure; the rubber pad can protect the crystal rod.

[0015] Compared with the prior art, the present invention provides a semiconductor cutting and fixing device, which has the following advantages:

[0016] 1. This utility model, through the setting of a connecting piston, establishes a movable connection between the movable frame and the fixed frame. The bottom end of the movable frame is fixedly connected to the slider of the slide rail. The connecting piston can adjust the distance between the movable frame and the fixed frame. During cutting, the limiting piston inside the fixed frame adjusts the position of the connecting plate so that the rubber pads at the four corners clamp the crystal rod. When the connecting piston is at its elongation limit, the limiting piston inside the movable frame controls the rubber pads to clamp the crystal rod. After a portion of the crystal rod is cut, the connecting piston inside the fixed frame contracts so that the rubber pads inside the fixed frame do not contact the crystal rod. Then, the connecting piston and the auxiliary piston drive the crystal rod forward a certain distance. Finally, the connecting piston inside the fixed frame clamps the crystal rod with the rubber pads, thereby achieving the effect of adjusting the position of the crystal rod.

[0017] 2. This utility model features a slide rail with a raised structure at the front end of the base plate, the height of which is the same as the thickness of the slide rail. The slide rail is symmetrically installed on the top of the base plate with the center as the reference. The movable frame is slidably connected to the base plate via the slide rail, and simultaneously connected to the fixed frame via a connecting piston. This method allows for adjustment of the position of the rubber pad during cutting by adjusting the extension of the limiting piston inside the movable frame, thus loosening the crystal rod. The distance between the movable frame and the fixed frame is then increased by the connecting piston. After the connecting piston reaches its extension limit, the rubber pad inside the movable frame contacts and fixes the crystal rod. This method allows for adjustment of the movable frame position during cutting, reducing the need for subsequent crystal rod position adjustments. When the crystal rod position needs to be adjusted, only the limiting piston inside the fixed frame needs to be retracted, and the distance between the movable frame and the fixed frame is adjusted by the connecting piston and auxiliary piston. Finally, the rubber pad inside the fixed frame clamps the crystal rod. Attached Figure Description

[0026] Please see Figure 1 - Figure 4 In this embodiment, a semiconductor cutting and fixing device includes: a base plate 1, a controller 11 fixedly installed on the top of the base plate 1, a slide rail 12 fixedly installed on the top of the base plate 1, a support column 13 fixedly installed at the rear end of the base plate 1, an auxiliary piston 14 inserted through the upper end of the support column 13, and a tray 15 fixedly installed at the front end of the auxiliary piston 14.

The movable frame 22 is movably connected to the fixed frame 2 through the connecting piston 21. The bottom end of the movable frame 22 is fixedly connected to the slider of the slide rail 12.

[0032] The movable frame 22 is slidably connected to the base plate 1 via the slide rail 12, and the limiting block 23 is symmetrically installed on the inner side of the four corners of the fixed frame 2 and the movable frame 22 with the center of the fixed frame 2 and the movable frame 22 as the reference.

[0033] The movable block 24 is symmetrically installed on the upper and lower sides of the limiting block 23, and the movable block 24 and the limiting block 23 are rotatably connected. The limiting piston 25 is installed at the end of the movable block 24 on the upper and lower sides of the limiting block 23.

[0034] The end of the limiting piston 25 is also fixedly installed with a movable block 24, and the movable block 24 at the end of the limiting piston 25 and the connecting block 26 form a rotatable connection. The connecting block 26 is symmetrically installed at the upper and lower ends of the connecting plate 27, and the connecting blocks 26 at the upper and lower ends of the connecting plate 27 are respectively connected to the movable blocks 24 at the ends of the limiting pistons 25 on the upper and lower sides.

[0036] In use, the movable frame 22 is movably connected to the fixed frame 2 via the connecting piston 21. The bottom end of the movable frame 22 is fixedly connected to the slider of the slide rail 12. The connecting piston 21 can adjust the distance between the movable frame 22 and the fixed frame 2. During cutting, the limiting piston 25 inside the fixed frame 2 adjusts the position of the connecting plate 27 so that the rubber pads 28 at the four corners clamp the crystal rod. When the connecting piston 21 is at its elongation limit, the limiting piston 25 inside the movable frame 22 controls the rubber pads 28 to clamp the crystal rod. After a portion of the crystal rod is cut, the connecting piston 21 inside the fixed frame 2 contracts so that the rubber pads 28 inside the fixed frame 2 do not contact the crystal rod. Then, the connecting piston 21 and the auxiliary piston 14 drive the crystal rod forward a certain distance. Finally, the connecting piston 21 inside the fixed frame 2 clamps the crystal rod with the rubber pads 28 to achieve the effect of adjusting the position of the crystal rod. The front end of the base plate 1 is provided with a protrusion structure with a height consistent with the thickness of the slide rail 12. The slide rail 12 is centered on the base plate 1. The movable frame 22 is symmetrically installed above the base plate 1 on both sides. It is slidably connected to the base plate 1 via the slide rail 12. At the same time, the movable frame 22 is movably connected to the fixed frame 2 via the connecting piston 21. This method allows the position of the rubber pad 28 to be adjusted by adjusting the extension of the limiting piston 25 inside the movable frame 22 during the cutting process, so that the rubber pad 28 releases the crystal rod. Then, the distance between the movable frame 22 and the fixed frame 2 is increased by the connecting piston 21. After the connecting piston 21 reaches its extension limit, the rubber pad 28 inside the movable frame 22 contacts the crystal rod and is fixed. This method allows the position of the movable frame 22 to be adjusted during cutting, thereby reducing the steps of subsequent crystal rod position adjustment. When the crystal rod position needs to be adjusted, it is only necessary to retract the limiting piston 25 inside the fixed frame 2, and then adjust the distance between the movable frame 22 and the fixed frame 2 via the connecting piston 21 and the auxiliary piston 14. Finally, the rubber pad 28 inside the fixed frame 2 clamps the crystal rod.
