Description

Technical Field

[0001] This application relates to the field of chip angle grinding technology, and more specifically, to a silicon controlled rectifier chip angle grinding machine. Background Technology

[0002] As an important semiconductor device, the silicon controlled rectifier (SCR) chip has wide applications in electronics, power, and other fields. In the SCR chip manufacturing process, the grinding process is a crucial step, directly affecting the chip's performance and quality. The main purpose of the grinding process is to remove burrs and sharp angles from the chip's edges, making them smooth and rounded. This improves the chip's mechanical strength and electrical performance, preventing problems such as electric field concentration and breakdown caused by edge defects during subsequent use.

[0003] A search revealed that Chinese patent CN119658552A discloses a chip angle grinding device and grinding method. This device drives a first roller and a second roller to rotate synchronously via the grinding body, enabling the grinding belt to continuously and stably grind the sides of the chip. Through the cooperation of the first and second rollers, the grinding belt can evenly distribute the grinding force over a large contact area, improving grinding efficiency.

[0004] The reduced number of chips that the above-mentioned device can grind at the same time results in unsatisfactory grinding efficiency. In view of this, we propose a silicon controlled rectifier chip angle grinding machine. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this application are:

[0020] 2) By providing multiple recesses on the grinding roller, the chip can contact the grinding belt at the recesses when the chip is being ground, so that the grinding belt can undergo elastic deformation, reducing the contact force between the chip and the grinding belt, thereby reducing the vibration generated when the chip is being ground.

[0021] 3) This application increases the inclination of the grinding belt at the grinding roller by setting an adjustment roller, thereby reducing the contact area between the grinding belt and the chip and suppressing the vibration generated during chip grinding. Attached Figure Description

[0026] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] Please see Figure 1 This application provides a technical solution:

[0028] A silicon controlled rectifier chip grinding machine includes a support frame 1 and a grinding belt 2. Multiple grinding rollers 3 are rotatably connected to the support frame 1. An adjusting roller 4 is provided between two adjacent grinding rollers 3. An elastic layer is provided on the outside of the adjusting roller 4. The adjusting roller 4 is rotatably connected to the support frame 1. The grinding belt 2 is sleeved on the outside of the grinding rollers 3. The adjusting roller 4 is located outside the grinding belt 2. The grinding belt 2 is recessed inward at the adjusting roller 4. A fixing plate 5 is provided on one side of the adjusting roller 4. The fixing plate 5 is rotatably mounted on the support frame 1. A first motor 6 is installed on the support frame 1. The output end of the first motor 6 is connected to one of the grinding rollers 3.

[0029] By setting multiple fixing disks 5, multiple chips can be fixed simultaneously. The first motor 6 drives the polishing roller 3 to rotate, which in turn moves the polishing belt 2. By rotating the fixing disks 5, the contact position between the chip and the polishing belt 2 is changed, enabling polishing of the chip corners and increasing polishing efficiency. Furthermore, the adjusting roller 4 forms a depression on the surface of the polishing belt 2, increasing the inclination of the polishing belt 2 at the polishing roller 3, reducing the contact area between the chip and the polishing belt 2, and thus reducing vibration during chip polishing.

[0030] like Figure 2As shown, a support rod 7 is installed on one side of the support frame 1. Multiple connecting shafts 701 are rotatably connected to the support rod 7. The connecting shafts 701 are parallel to the axis of the grinding roller 3. A fixed disk 5 is fixedly installed at one end of the connecting shaft 701, and a worm gear 702 is fixedly connected to the other end. A rotating shaft 703 is rotatably connected to the support rod 7. Multiple worm gear sections 704 are fixedly provided on the rotating shaft 703. The worm gear 702 is meshed with the worm gear section 704. A second motor 8 is fixedly installed on the support rod 7. The output end of the second motor 8 is connected to the rotating shaft 703 for transmission. The rotation direction of the adjusting roller 4 is opposite to that of the fixed disk 5.

[0031] The second motor 8 can drive the worm gear 704 to rotate, thereby synchronously driving multiple fixed disks 5 to rotate synchronously and simultaneously grind multiple chips. The transmission method of worm wheel 702 and worm gear 704 can increase the stability of fixed disks 5 and suppress chip vibration when the chip contacts the grinding belt 2 for grinding.

[0032] like Figure 3 As shown, the grinding roller 3 is provided with multiple recesses 301, and multiple fixing disks 5 are located at different heights, with the positions of the fixing disks 5 corresponding to the recesses 301.

[0033] When the chip contacts the polishing belt 2 for polishing, the polishing belt 2 at the recess 301 can undergo elastic deformation to avoid excessive contact force between the polishing belt 2 and the chip, which would cause severe vibration during chip polishing.

[0034] Preferably, the support frame 1 is provided with a guide rail 101, and a slider 102 is slidably disposed within the guide rail 101. The slider 102 is connected and fixed to the support rod 7. The support frame 1 is provided with a third motor 9, and the output end of the third motor 9 is connected to a threaded rod 901. The threaded rod 901 passes through the slider 102 and is threadedly connected to it. The third motor 9 can drive the threaded rod 901 to rotate, thereby adjusting the position of the support rod 7 and changing the distance between the fixed disk 5 and the grinding roller 3. The user can select a fixed disk 5 of the corresponding size according to the size of the chip, and by adjusting the distance between the fixed disk 5 and the grinding roller 3, the device can be applied to the grinding operation of chips of different sizes.
