[0002] A crystal oscillator, also known as a crystal oscillator, is a quartz crystal resonator made by cutting a thin slice from a quartz crystal at a certain azimuth angle. Adding the crystal element of the IC to form the oscillation circuit inside the package forms a complete crystal oscillator. Its products are generally packaged in a metal shell, or in a glass shell, ceramic or plastic package to form a crystal oscillator assembly. The ceramic base used in the crystal oscillator assembly can effectively support the crystal. The ceramic sheet needs to be double-sided tested before assembly to ensure that it meets the requirements for use.

[0003] However, in the existing crystal oscillator assembly production process, after one side of the ceramic sheet is inspected, it needs to be manually flipped over to inspect the other side, resulting in low inspection efficiency of the ceramic sheet, thereby affecting the production efficiency of the crystal oscillator assembly. This solution solves this technical problem. Utility Model Content

[0027] The driving mechanism 2 is a stepping motor, and the output shaft of the stepping motor is connected to the rotating mechanism 3 .

[0028] The output shaft of the stepper motor is connected to the rotating mechanism 3 through the connecting shaft 7. A sensing block 8 is arranged on the side of the connecting shaft 7. A sensing sensor 1 81 and a sensing sensor 2 82 are respectively arranged on the outer periphery of the connecting shaft 7 on the fixing device 1. The sensing block 8 is swingably arranged between the sensing sensor 1 81 and the sensing sensor 2 82. Both the sensing sensor 1 81 and the sensing sensor 2 82 are electrically connected to the stepper motor.

[0029] The vacuum suction cup 5 is a suction cup with a buffer bracket, and a plurality of vacuum suction cups 5 are evenly distributed.

[0030] The rotating mechanism 3 is a rotating arm.

[0031] A flange portion 31 is provided at one end of the rotating arm, and the rotating arm is connected to the connecting shaft 7 via the flange portion 31 .

[0032] The fixing device 1 comprises a vertical plate 11 for fixing the driving mechanism 2 and a supporting plate 12 connected to the vertical plate 11 .

[0033] A backing plate 13 is disposed on the bottom side of the carrying plate 12 . A limiting groove 131 is defined on the backing plate 13 . The carrying plate 12 is slidably disposed in the limiting groove 131 .

[0034] A plurality of bolt holes 132 are formed in the limiting groove 131 , and waist-shaped holes 121 are formed at corresponding positions on the bearing plate 12 . The backing plate 13 and the bearing plate 12 are fastened and connected by bolts which penetrate the bolt holes 132 and the waist-shaped holes 121 in sequence.

[0035] The specific working process of this utility model:

[0036] First, the flipping device is installed on the detection equipment through the pad 13, and the position of the flipping device on the detection equipment is fine-tuned by sliding the bearing plate 12 in the limiting groove 131 and adjusting the waist-shaped hole 121. Then, the ceramic sheet 6 that has been inspected on one side of the conveyor belt in the previous process is conveyed to one side of the flipping device and stops. At this time, the stepper motor drives the rotating arm to rotate until the sensing block 8 and the sensing sensor 81 are inductively contacted. The sensing sensor 81 sends a signal to stop the stepper motor. At this time, the vacuum suction cup 5 connected to the rotating arm is located directly above the ceramic sheet 6. The vacuum suction cup 5 is operated to suck up the ceramic sheet 6, and then the stepper motor rotates in the opposite direction. When the stepper motor drives the rotating arm to rotate until the other side of the ceramic sheet 6 is located above the conveyor belt, the vacuum suction cup 5 releases the ceramic sheet 6, and the stepper motor continues to rotate until the sensing block 8 and the sensing sensor 82 are inductively contacted and stop. At this time, the ceramic sheet 6 is separated from the vacuum suction cup 5 and contacts the conveyor belt, thereby completing the flipping of the ceramic sheet 6. The conveyor belt transports the ceramic sheet 6 to the detection area for detection of the other side. The stepper motor rotates again until the sensing block 8 and the sensing sensor 81 are inductively contacted, and then the next ceramic sheet 6 is sucked and flipped through the vacuum suction cup 5.

[0037] The driving mechanism 2 is driven to move the rotating arm, so that the vacuum suction cups 5 on the suction cup mounting plate 4 can suck and flip the ceramic sheet 6. Compared with manual flipping, the vacuum suction cups 5 have a better suction effect on the ceramic sheet 6, and the flipping efficiency of the ceramic sheet 6 is higher, thereby improving the detection efficiency of the ceramic sheet 6;

[0038] The driving mechanism 2 is a stepper motor, and the arm flips the ceramic sheet 6 through the cooperation of the induction block 8, the induction sensor 1 81 and the induction sensor 2 82. The stepper motor has a low cost, runs more stably and reliably, has low energy consumption, and has a stronger applicability of the flipping device.

[0039] By sliding the support plate 12 in the limiting groove 131 and adjusting the waist-shaped hole 121 to fine-tune the position of the support plate 12, the installation of the flip device is more convenient and quick.

[0040] The vacuum suction cups 5 are evenly attracted to the ceramic sheet 6 , so that the force on the ceramic sheet 6 is more uniform, and the turning of the ceramic sheet 6 is safer and more reliable.
