Description

Technical Field

[0001] The invention belongs to the technical field of electronic accessories, and in particular relates to a quartz crystal resonator sealing and welding machine. Background Art

[0002] A quartz crystal resonator is a resonant element made using the piezoelectric effect of a quartz crystal. It is an important electronic component used to stabilize and select frequency and has been increasingly widely used in various military and civilian products such as wired communications, wireless communications, radio and television, satellite communications, electronic measuring instruments, microcomputer processing, digital instruments, and clocks. Its main body is a quartz wafer. In the manufacturing process, the wafer is usually placed in a base and then sealed using a sealing device. However, the sealing device in the prior art has a poor positioning effect on the base and the sealing cover, which can easily cause the base and the sealing cover to shift during sealing, resulting in an increased scrap rate. In the prior art, the encapsulated quartz crystal resonator is blown away from the inside of the positioning groove by using gas. However, during the sealing process, the base is easily deformed due to the high sealing temperature and the quartz crystal resonator cannot be removed smoothly, which brings trouble to the production of the quartz crystal resonator. Summary of the invention

[0003] The object of the present invention is to provide a quartz crystal resonator sealing machine, which positions the corresponding base and sealing cover respectively under the action of a movable plate and a cylinder, and lowers the height of the movable plate and then blows the formed quartz crystal resonator, thereby solving the problem that the sealing device in the prior art has a poor positioning effect on the base and the sealing cover, which easily causes the base and the sealing cover to shift during sealing, resulting in an increased scrap rate. In addition, in the prior art, the base is easily deformed due to the excessively high sealing temperature, and the quartz crystal resonator cannot be removed smoothly, which brings troubles to the production of the quartz crystal resonator.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a quartz crystal resonator sealing and welding machine, comprising a mounting plate, a movable plate is arranged above the mounting plate, a base is arranged on the upper side of the middle position of the movable plate, a support plate is arranged below the base, a fixed plate is fixed at the middle position of the upper wall of the mounting plate corresponding to the rear side of the movable plate, a cylinder is fixed to the upper wall of the front side of the fixed plate, a spring is arranged below the power output end of the cylinder, and electric push rods are symmetrically fixed on the left and right sides of the upper wall of the mounting plate.

[0006] Furthermore, guide rods are slidably connected at the four corners of the movable plate, and the bottoms of the guide rods are fixed to the upper surface of the mounting plate, and the upper ends of the electric push rods are fixedly connected to the lower wall of the movable plate.

[0007] Furthermore, a positioning groove is provided at the middle position of the movable plate, and the base is located inside the positioning groove.

[0008] Furthermore, a mounting rod is fixed below the support plate by bolts, and the mounting rod is fixedly connected to the mounting plate by bolts.

[0009] Furthermore, an upper connecting plate and a lower connecting plate are fixed to the upper and lower ends of the spring respectively, a connecting rod is provided at the lower end of the spring, and the upper connecting plate and the lower connecting plate are fixedly connected to the power output end and the connecting rod of the corresponding cylinder respectively.

[0010] Furthermore, a limiting rod is fixed on the inner side of the spring corresponding to the lower wall of the upper connecting plate, the outer side of the limiting rod is slidably connected to the limiting sleeve, and the limiting sleeve is adapted to the limiting rod, and a sponge pad is fixed to the bottom of the connecting rod, and the sponge pad is located directly above the base.

[0011] The present invention has the following beneficial effects:

[0012] The present invention provides a cylinder, a movable plate, a support plate and a positioning groove. When the base is sealed and welded, the base is first placed inside the positioning groove, and then the sealing cover is placed at the position to be welded on the base. At this time, the power output end of the cylinder is controlled to extend. The extension of the power output end of the cylinder causes the sponge pad at the bottom of the connecting rod to move toward the sealing cover. When the sponge pad moves onto the sealing cover and the sponge pad abuts against the sealing cover, the sealing cover can be positioned. When the sealing cover and the base are in a positioned state, the base and the sealing cover can be welded. Compared with the prior art, the present invention positions the base through the positioning groove, and applies pressure to the sealing cover through the sponge pad to position the sealing cover, so that the position of the sealing cover and the base is fixed, which is convenient for welding the sealing cover and the base, and can avoid the increase in welding scrap rate due to the offset of the sealing cover and the base. This solves the problem that the sealing device in the prior art has poor positioning effect on the base and the sealing cover, which easily causes the base and the sealing cover to offset during sealing and welding, resulting in an increase in scrap rate.

[0013] The present invention provides a guide rod, a movable plate and an electric push rod. After the base and the sealing cover are sealed and welded, the power output end of the cylinder is first controlled to retract. When the power output end of the cylinder is retracted, the sponge pad moves upward. At this time, the electric push rod is operated to retract the power output end of the electric push rod. Since the power output end of the electric push rod is fixed to the lower wall of the movable plate, the movable plate will move downward when the power output end of the electric push rod is retracted. When the movable plate moves to the point where the base is completely separated from the interior of the positioning groove, the quartz crystal resonator is separated from the upper surface of the support plate by using gas to complete the removal. Compared with the prior art, the present invention controls the electric push rod to move the movable plate downward so that the quartz crystal resonator after the sealing is completed can be separated from the inside of the positioning groove, and even if it is deformed during the sealing, it will not be stuck in the inside of the movable plate. The quartz crystal resonator can be separated from the present invention by blowing gas to perform the next sealing operation, which solves the problem in the prior art that the base is easily deformed due to the high sealing temperature and the quartz crystal resonator cannot be removed smoothly, which brings troubles to the production of quartz crystal resonators.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In the state of positioning the sealing cover of the present invention, the horizontal plane of the upper wall of the base 5 is higher than the horizontal plane of the upper wall of the movable plate 3, and the cylinder 1 can limit the stroke of the cylinder 1 in actual use, and the stroke length of the cylinder 1 is based on the sponge pad 1031 being sufficient to form a positioning effect on the sealing cover, and the rear of the movable plate 3 A fixed plate 2 is fixed at the middle position of the upper wall of the corresponding mounting plate 6 on the side, and the cross-section of the fixed plate 2 is L-shaped. The movement of the cylinder 1 fixed on the upper wall on the front side of the fixed plate 2 can drive the sponge pad 1031 to move up and down. The elasticity of the spring 104 arranged below the power output end of the cylinder 1 can prevent the sponge pad 1031 from hitting the sealing cover when the power output end of the cylinder 1 moves. The elasticity of the spring 104 can greatly reduce the impact on the sealing cover. The electric push rods 4 symmetrically fixed on the left and right sides of the upper wall of the mounting plate 6 can drive the movable plate 3 to move up and down. The electric push rods 4 are prior art and their models are not limited here. When the electric push rods 4 are working, the power output ends of the two electric push rods 4 move up or down synchronously.
