Description

Technical Field

[0001] The invention relates to the technical field of crystal resonator processing, in particular to a processing technology for a crystal resonator. Background Art

[0002] A crystal resonator is an electronic component that uses the piezoelectric effect of a quartz crystal to generate an extremely stable frequency signal. In high-power applications or applications that require particularly high stability and precision, crystal resonators with larger physical sizes are used. These resonators can be several centimeters or even larger. Larger crystal resonators have better frequency stability, higher load capacity, and stronger anti-interference capabilities. To meet the different installation requirements of crystal resonators, the pins of the crystal resonators must be cut into corresponding lengths during the crystal resonator processing process so that all pins have the same length when straightened, which is convenient for subsequent installation and welding, thereby ensuring the reliability of the electrical connection of the crystal resonator.

[0003] Existing cutting of crystal resonator pins usually requires workers to measure the length of the pins, then mark the cutting position on the crystal resonator pins, and then use cutting equipment (such as pliers and pin shears, etc.) to cut the crystal resonator pins.

[0004] The above-mentioned cutting of the crystal resonator pins has the following deficiencies: during the cutting process of the crystal resonator pins by the staff, the pins of the crystal resonator are easily in a bent state during measurement, resulting in poor consistency in the lengths of the two pins of the crystal resonator after cutting, and it is easy for the pins of the crystal resonator to be unable to be stably soldered to the circuit board, thereby affecting the reliability of the electrical connection; secondly, the pins of the crystal resonator are not protected during the above-mentioned cutting process, and the crystal resonator pins are easily deformed or damaged due to cutting, which will affect the correct installation and electrical connection of the crystal resonator.

[0044] S2, wafer processing: According to the required frequency characteristics and temperature coefficient requirements, select the appropriate cutting angle (such as AT cutting, SC cutting, etc.), and perform directional cutting on the quartz crystal rod obtained in step S1 to obtain a wafer. Next, a series of surface treatments are performed on the cut wafer, including rough grinding, fine grinding, polishing and cleaning, etc., to improve the surface flatness, and finally obtain a wafer that meets the requirements.

At this time, the pins are pressed tightly against the fixed block 41 and the support plate 40 at the same time. The sliding plate 42 moves forward so that the pins of the crystal resonator are straightened from back to front until the sliding plate 42 moves to contact the positioning bar 502, and the rack four 466 continues to move forward, while the L-shaped plate 463 stops moving, and the spring two 465 is stretched and deformed, and the movement of the L-shaped plate 463 is compensated by the deformation of the spring two 465.

[0061] like Figure 4As shown, a lower pressure rod 52 is slidably penetrated on the fixed block 41 and the corresponding sliding plate 42, a push plate 520 is fixedly provided on the upper end surface of the lower pressure rod 52, a spring 521 sleeved on the lower pressure rod 52 is fixedly provided between the push plate 520 and the fixed block 41, and a plurality of equidistantly distributed positioning holes 522 are penetrated on the placement plate 1.

[0062] In the initial state, the pressing rod 52 and the positioning hole 522 are staggered with each other. During operation, the pins of the crystal resonator are straightened and then the lifting plate 2 continues to move downward. After the lifting plate 2 moves to contact with the pushing plate 520, the lifting plate 2 pushes the pushing plate 520 to move downward synchronously. The spring three 521 is compressed and deformed, and the pushing plate 520 drives the pressing rod 52 to move downward synchronously. After the pressing rod 52 moves downward into the positioning hole 522, the position of the support plate 40 is fixed by the cooperation between the pressing rod 52 and the positioning hole 522, so as to avoid the cutting of the pins by the cutting tool 21 during the cutting process, causing the support plate 40 to move backward, thereby causing the cutting surface to be uneven and the error to increase.

[0063] During the specific work, the staff adjusts the front and rear positions of the cutting tool 21 through the adjustment group 50, and then the staff places multiple crystal resonators in each placement slot 10 respectively, and makes the two pins of each crystal resonator be respectively located between the corresponding fixed block 41 and the two clamping plates 430, and then the limiting group 45 works to limit the crystal resonator. In the process of the limiting group 45 limiting the crystal resonator, the clamping group 43 and the pressing group 44 work at the same time, and the pins of the crystal resonator are pressed tightly against the fixed block 41 and the support plate 40 at the same time, and then the hydraulic cylinder 20 works to drive the lifting plate 2 to move downward, and the positioning group 51 works to fix the position of the support plate 40. The pins of the crystal resonator are straightened from front to back through the cooperation between the clamping plate 430 and the fixed block 41 and between the lower pressure plate 441 and the support plate 40. After the sliding plate 42 moves to be close to the positioning bar 502, the lower pressure rod 52 is pushed to the positioning hole 522 to fix the position of the support plate 40. Then the lifting plate 2 drives the multiple cutting tools 21 to continue to move downward to cut the pins of all the crystal resonators at the same time. After the cutting is completed, the limit and clamping of the crystal resonator and its pins are released. Then the lifting plate 2 moves upward and the linkage group 46 drives the sliding plate 42 to move backward and reset.
