Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of crystal oscillator grinding technology, and more specifically, to a crystal oscillator grinder. Background Technology

[0002] A crystal oscillator is an electronic component made using the piezoelectric effect of quartz crystals. It is mainly used as a rate and thickness sensing element in film thickness control systems. Crystal oscillators are derived from polyhedral quartz rods, which are cut and ground into thin discs, typically 0.23 mm thick and 13.98 mm in diameter. After edge trimming, polishing, and cleaning, each disc is fully plated with metal electrodes on the front side and keyhole-shaped electrodes on the back side.

[0003] After the crystal oscillator is cut, it needs to be ground. The current grinding method is to put it into a grinding disc for batch processing. Each time, it is necessary to stop and wait for the loading and unloading process, which takes a long time and has low continuous processing efficiency. Moreover, it is impossible to wash the ground crystal oscillator.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0033] like Figures 1-4 As shown, a crystal oscillator polisher according to an embodiment of the present disclosure includes:

[0034] Equipment frame 1 and conveyor belt 2, with conveyor belt 2 installed inside equipment frame 1;

[0035] The lifting controller 3 and the grinding assembly 4 are provided. The lifting controller 3 is located on the outside of the equipment frame 1, and the grinding assembly 4 is located inside the conveyor belt 2 and the equipment frame 1.

[0036] Rinse assembly 5 is located on top of equipment rack 1;

[0037] The grinding assembly 4 includes several mold seats 4-1, which are evenly distributed on the surface of the conveyor belt 2. Several shallow grooves 4-2 are opened on the surface of the mold seats 4-1. Through holes 4-3 are opened at the bottom of the shallow grooves 4-2 and the conveyor belt 2. A top cover 4-4 is provided at the output end of the lifting controller 3. A grinding roller 4-5 is rotatably connected inside the top cover 4-4. The grinding roller 4-5 is rotated by a motor. A vacuum cleaner 4-6 is provided on the top of the top cover 4-4. A vacuum pump 4-7 is provided inside the equipment frame 1. A bottom cover 4-8 is fixedly connected inside the equipment frame 1. The upper surface of the bottom cover 4-8 slides against the surface of the conveyor belt 2. The suction end of the vacuum pump 4-7 is connected to the bottom cover 4-8. There are extension platforms 4-9 on both sides of the bottom cover 4-8.

[0038] In some examples, to achieve continuous grinding, a grinding assembly 4 is designed. Multiple mold seats 4-1 are set on the conveyor belt 2. Multiple shallow grooves 4-2 are opened on the surface of the mold seats 4-1 and through holes 4-3 are opened inside. The shallow grooves 4-2 are used to place crystal oscillators. The through holes 4-3 penetrate the conveyor belt 2. The output end of the lifting controller 3 is connected to the top cover 4-4, which can control the lifting of the top cover 4-4. A grinding roller 4-5 is set inside the top cover 4-4, which can rotate at high speed to grind the crystal oscillators in the shallow grooves 4-2. A vacuum pump 4-7 and a bottom cover 4-8 are set inside the equipment frame 1, which can make the bottom cover 4-8 generate suction. The bottom cover 4-8 is attached to the inner surface of the conveyor belt 2 and is located directly below the top cover 4-4. It can cooperate with the top cover 4-4 to clamp the conveyor belt 2. The suction can fix the crystal oscillators in the shallow grooves 4-2. A vacuum cleaner 4-6 is also set on the top cover 4-4 to absorb dust.

[0039] like Figures 1-4 As shown, this embodiment proposes a rinsing assembly 5, which includes a crossbeam 5-1. The crossbeam 5-1 is set on the top of the equipment frame 1. A drive screw 5-2 is installed inside the crossbeam 5-1. A pair of slide rails 5-3 are provided inside the crossbeam 5-1. A movable frame 5-4 is slidably connected to the slide rails 5-3. The movable frame 5-4 is connected to the drive screw 5-2 by a threaded engagement. A pair of flushing nozzles 5-5 are provided on the top of the movable frame 5-4. A connecting pipe 5-6 is provided at the upper end of the flushing nozzles 5-5. A water collection tank 5-7 is opened at the bottom of the equipment frame 1.

[0040] In some examples, a rinsing assembly 5 is designed to achieve the effect of rinsing the ground crystal oscillator. A crossbeam 5-1 is set on the top of the equipment frame 1, and a drive screw 5-2 and a slide rail 5-3 are installed inside. A movable frame 5-4 is connected to the drive screw 5-2 and the slide rail 5-3. The movable frame 5-4 can be controlled to move linearly by a drive screw. Two flushing nozzles 5-5 and a connecting pipe 5-6 are installed on the movable frame 5-4, which can be connected to a water supply device to flush the crystal oscillator with downward water flow. A water collection tank 5-7 is opened at the bottom of the equipment frame 1 to collect the flushed water.

[0041] For example, such as Figure 3 As shown, the ratio of the bottom opening width of the top cover 4-4 to the width of the mold base 4-1 is 2:1.

[0042] In some examples, by increasing the size of the top cover 4-4, the mold base 4-1 can move inside the top cover 4-4, allowing the grinding roller 4-5 to move on the surface of the crystal oscillator, thus completing uniform grinding.

[0043] For example, such as Figure 4 As shown, the flushing nozzle 5-5 corresponds to the position of the shallow groove 4-2.

[0044] In some examples, the water flowing down can directly cover the surface of the crystal oscillator by the position of the flushing nozzle 5-5 corresponding to the shallow groove 4-2.

[0045] For example, such as Figure 4 As shown, the depth of the shallow groove 4-2 is less than the thickness of the crystal oscillator.

[0046] In some examples, the crystal oscillator protrudes from the surface of the mold base 4-1 and contacts the surface of the grinding roller 4-5 through the shallow groove 4-2 at a lower depth.

[0047] When grinding is required, place the crystal oscillator into the shallow trough 4-2, start the conveyor belt 2 to begin conveying, and after the mold base 4-1 moves below the top cover 4-4, start the lifting controller 3 to cover the mold base 4-1 with the top cover 4-4 and clamp the conveyor belt 2 together with the bottom cover 4-8. Start the vacuum pump 4-7 and the grinding roller 4-5 to fix the crystal oscillator in the shallow trough 4-2 by suction. Start controlling the conveyor belt 2 to move slowly. During the movement, the grinding is completed by the grinding roller 4-5. During the grinding process, start the vacuum pump 4-7 to absorb the dust. While grinding, continue to put the crystal oscillator into the mold base 4-1. When it reaches below the flushing nozzle 5-5 after grinding, open the flushing nozzle 5-5 to flush downwards. At the same time, start the drive screw to control the moving frame 5-4 to move left and right repeatedly. The flushing water flows into the water collection tank 5-7. The mold base 4-1 falls downwards as the angle of the conveyor belt 2 changes, and can be placed in a container to collect it.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
