Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, specifically to a die-attachment ring clamp for a die-cutting machine. Background Technology

[0002] Due to the inherent properties of the chip material, optical communication semiconductor chips require a dicing machine during the dicing process. The chip is then fixed by being glued onto a blue film, which is then secured to a mounting ring (a common fixture in semiconductor manufacturing) before being fitted onto the equipment for further processing.

[0003] In the existing technology, the chip cleaving machine uses a fixing fixture to fix the chip-attached chip ring. When replacing the chip ring, the fixing fixture needs to be disassembled and reinstalled, which is time-consuming and labor-intensive. After long-term use, the chip wears out severely and the stability is poor. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the time-consuming and labor-intensive problem of replacing the patch ring in the prior art, thereby providing a patch ring clamp for a chipper.

[0005] To solve the above-mentioned technical problems, this utility model provides a chipping ring clamp for a chipping machine, comprising: a base plate, a card plate, and an elastic element; the card plate is slidably disposed on the base plate and is used to press the workpiece to be fixed; the elastic element is disposed between the base plate and the card plate, and the elastic element has an elastic force that drives the card plate to move toward the workpiece to be installed; wherein, in the pick-and-place state, the card plate moves away from the workpiece to be fixed and the elastic element is compressed; in the pressed state, the elastic element drives the card plate to move toward the workpiece to be fixed.

[0006] In use, with the base fixed, the card plate is pulled away from the base and moved away from the workpiece to be fixed, compressing the elastic element. Once the workpiece is in place, the card plate is released, and under the elastic force of the elastic element, the card plate moves back towards the workpiece to be fixed, thus pressing the card plate firmly against the workpiece and fixing it in the designated position without moving or shaking. The elastic element enables the clamp to have a self-locking function, eliminating gaps in the placement of the workpiece. This clamp structure facilitates the handling of the workpiece without requiring disassembly and reassembly. The chip-mounting ring clamp for the chipper provided by this utility model solves the problem of time-consuming and labor-intensive replacement of the chip-mounting ring in the prior art.

[0007] Optionally, the base plate is provided with a first sliding guide rail, and the card plate is provided with a second sliding guide rail that is slidably connected to the first sliding guide rail. Through this arrangement, the sliding connection between the first and second sliding guide rails guides and limits the sliding movement of the card plate relative to the base plate.

[0008] Optionally, the base plate is provided with a mounting groove, the first sliding guide rail is disposed in the mounting groove, the first end of the mounting groove is provided with a notch for the second sliding guide rail to pass through, and the sidewall of the second end of the mounting groove is used to block and cooperate with the second sliding guide rail. With the above configuration, the second sliding guide rail passes through the notch, allowing the card plate to move towards the first end of the base plate. When the elastic element drives the card plate to reset, the sidewall of the second end of the mounting groove forms a block with the second sliding guide rail, which can prevent the second sliding guide rail from detaching from the first sliding guide rail.

[0009] Optionally, the first end of the mounting groove is provided with two mounting blocks, forming a notch between the two mounting blocks. The mounting blocks are connected to the first end of the elastic element, and the card plate is provided with a compression member, which abuts against the second end of the elastic element. With the above arrangement, when the card plate moves toward the first end of the base plate, the compression member and the mounting blocks cooperate to compress the elastic element, so that the elastic element has an elastic force to drive the card plate to reset. When the card plate presses against the workpiece to be fixed, the elastic element pushes the compression member to move the card plate toward the second end of the base plate.

[0010] Optionally, the mounting block is provided with a guide shaft, and the elastic element is sleeved on the guide shaft. With this configuration, the guide shaft can guide the direction of the elastic force of the elastic element, and can also limit the stroke of the card plate, preventing the second sliding guide rail from disengaging from the first end of the first sliding guide rail, thus improving the service life of the fixture.

[0011] Optionally, the mounting block is provided with a screw hole, and the guide shaft is provided with an external thread, the guide shaft being threadedly connected to the mounting block. Through this configuration, the length of the guide shaft can be adjusted via the threaded connection between the guide shaft and the mounting block, thereby adjusting the stroke of the card plate to accommodate workpieces of different sizes to be fixed.

[0012] Optionally, the end face of the card plate that contacts the workpiece to be fixed is set as an inclined surface. This inclined surface prevents the workpiece from detaching, improving the stability of the fixation.

[0013] Optionally, the card plate is provided with a handle. This handle provides a point of force for gripping, making it easy to pull the card plate.

[0014] Optionally, the base plate is provided with mounting holes for installing fasteners to secure the base plate in place. Attached Figure Description

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] This embodiment provides a structure for a chipper patch ring clamp 13 that is easy to handle, used to fix the patch ring.

[0029] like Figure 1 , Figure 2 The image shows a specific embodiment of a chipping machine patching ring clamp 13 provided in this embodiment, comprising: a base plate 1, a card plate 2, and an elastic element 3; the card plate 2 is slidably disposed on the base plate 1, and the card plate 2 is used to press the workpiece 14 to be fixed; the elastic element 3 is disposed between the base plate 1 and the card plate 2, and the elastic element 3 has an elastic force that drives the card plate 2 to move toward the workpiece to be installed; wherein, in the pick-and-place state, the card plate 2 moves toward a direction away from the workpiece 14 to be fixed, and the elastic element 3 is compressed; in the pressed state, the elastic element 3 drives the card plate 2 to move toward a direction closer to the workpiece 14 to be fixed.

[0030] In use, with the base fixed, the card plate 2 is pulled relative to the base and moved away from the workpiece 14 to be fixed. The elastic element 3 is compressed. After the workpiece 14 is placed in position, the card plate 2 is released. Under the elastic force of the elastic element 3, the card plate 2 is driven to move closer to the workpiece 14 to reset, thereby pressing the card plate 2 against the workpiece 14 and fixing it in the designated position so that the workpiece 14 will not move or shake on its own. The elastic element 3 enables the clamp to form a self-locking function, thereby eliminating the gap in the placement of the workpiece 14. This clamp structure makes it easy to pick up and drop the workpiece 14 without disassembling and reinstalling the clamp. The chipper ring clamp 13 provided in this embodiment solves the problem of time-consuming and laborious replacement of the chipper ring in the prior art.

[0031] like Figure 3-5 As shown, in the chipper applicator ring clamp 13 provided in this embodiment, a first sliding guide rail 4 is provided on the base plate 1, and a second sliding guide rail 5 is provided on the card plate 2, which is slidably connected to the first sliding guide rail 4. The sliding connection between the first sliding guide rail 4 and the second sliding guide rail 5 guides and limits the sliding movement of the card plate 2 relative to the base plate 1. Alternatively, as an alternative embodiment, the first sliding guide rail 4 is disposed on the card plate 2, and the second sliding guide rail 5 is disposed on the base plate 1.

[0032] It should be further noted that the first sliding guide rail 4 and the second sliding guide rail 5 can only slide relative to each other along the length direction of the first sliding guide rail 4, and cannot move relative to each other along the thickness direction of the first sliding guide rail 4.

[0033] like Figure 3-5 As shown, in the chipper applicator clamp 13 provided in this embodiment, the base plate 1 is provided with a mounting groove 6, the first sliding guide rail 4 is disposed in the mounting groove 6, the first end of the mounting groove 6 is provided with a notch for the passage of the second sliding guide rail 5, and the sidewall of the second end of the mounting groove 6 is used to block and cooperate with the second sliding guide rail 5. The second sliding guide rail 5 passes through the notch, allowing the card plate 2 to move towards the first end of the base plate 1. When the elastic member 3 drives the card plate 2 to reset, the sidewall of the second end of the mounting groove 6 forms a block with the second sliding guide rail 5, preventing the second sliding guide rail 5 from detaching from the first sliding guide rail 4. Alternatively, as an alternative embodiment, the mounting groove 6 can be omitted, and a blocking block for blocking the second sliding guide rail 5 can be provided at the second end of the first sliding guide rail 4.

[0034] like Figure 3-5As shown, in the chipping machine mounting ring fixture 13 provided in this embodiment, the first end of the mounting groove 6 is provided with two mounting blocks 7, forming a notch between the two mounting blocks 7. The mounting blocks 7 are connected to the first end of the elastic member 3. The card plate 2 is provided with a compression member 8, which abuts against the second end of the elastic member 3. When the card plate 2 moves toward the first end of the base plate 1, the compression member 8 and the mounting blocks 7 cooperate to compress the elastic member 3, so that the elastic member 3 has an elastic force to drive the card plate 2 to reset. When the card plate 2 presses the workpiece 14 to be fixed, the elastic member 3 pushes the compression member 8 to move the card plate 2 toward the second end of the base plate 1. Alternatively, as an alternative embodiment, the mounting blocks 7 can be omitted, and the sidewall of the first end of the mounting groove 6 is connected to the first end of the elastic member 3.

[0035] like Figure 3 , Figure 4 As shown, in the chipper applicator ring clamp 13 provided in this embodiment, the mounting block 7 is provided with a guide shaft 9, and the elastic element 3 is sleeved on the guide shaft 9. The guide shaft 9 can guide the direction of the elastic force of the elastic element 3, and can also limit the stroke of the card plate 2, preventing the second sliding guide rail 5 from disengaging from the first end of the first sliding guide rail 4, thereby improving the service life of the clamp. In addition, as an alternative embodiment, the guide shaft 9 can be omitted, and the stroke between the first sliding guide rail 4 and the mounting groove 6 is used for the limiting groove of the elastic element 3.

[0036] like Figure 3 , Figure 4 As shown, in the chipper applicator clamp 13 provided in this embodiment, the mounting block 7 is provided with a screw hole, and the guide shaft 9 is provided with an external thread. The guide shaft 9 is threadedly connected to the mounting block 7. Through the threaded connection between the guide shaft 9 and the mounting block 7, the length of the guide shaft 9 can be adjusted, thereby adjusting the stroke of the card plate 2 to accommodate workpieces 14 of different sizes to be fixed. Alternatively, as an alternative implementation, the guide shaft 9 can also be connected to the mounting block 7 by snap-fit ​​or other detachable means, allowing for the replacement of guide shafts 9 of different lengths depending on the application.

[0037] like Figure 1 , Figure 2 As shown, in the chipper applicator ring fixture 13 provided in this embodiment, the end face of the card plate 2 that contacts the workpiece 14 to be fixed is set as an inclined surface 10. The inclined surface 10 can prevent the workpiece 14 to be fixed from detaching and improve the stability of the fixation. In addition, as an alternative embodiment, the end face of the card plate 2 that contacts the workpiece 14 to be fixed can also be set as an arc-shaped surface.

[0038] like Figure 1 , Figure 2 , Figure 5 As shown, in the chipper applicator clamp 13 provided in this embodiment, the card plate 2 is provided with a handle 11. The handle 11 provides a gripping force point, which can facilitate pulling the card plate 2. In addition, as an alternative embodiment, the handle 11 can be omitted, and a groove for facilitating force application can be provided on the card plate 2.

[0039] like Figure 1-4 As shown, in the chipping machine patching ring fixture 13 provided in this embodiment, the base plate 1 is provided with mounting holes 12, which are used to install fasteners so that the base plate 1 is fixedly installed.

[0040] How to use:

[0041] like Figure 1 As shown, the chipping machine patching ring clamp 13 provided in this embodiment, when in use, has the base fixed, and the card plate 2 is pulled to move away from the workpiece 14 to be fixed relative to the base. The elastic element 3 is compressed. When the workpiece 14 to be fixed is placed in place, the card plate 2 is released. Under the action of the elastic force of the elastic element 3, the card plate 2 is driven to move and reset towards the workpiece 14 to be fixed, so that the card plate 2 presses the workpiece 14 to be fixed, so that the workpiece 14 to be fixed is fixed in the designated position and will not move or shake on its own.

[0042] like Figure 6 As shown, the chipping machine patching ring clamp 13 described in the above embodiment is applied to the whole machine. The workpiece 14 to be fixed is first clamped into the two limiting blocks 15, and then the card plate 2 is slid by pulling the handle 11, and the workpiece 14 to be fixed is fixed on the whole machine by the elastic force of the elastic element 3.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
