Description

Technical Field

[0001] The utility model belongs to the technical field of crystal oscillator cold-pressing welding tooling, in particular to a plug-in type crystal oscillator cold-pressing welding die and a welding robot. Background Art

[0002] Crystal oscillators mainly provide basic clock signals for electronic systems. Usually, a system shares one crystal oscillator to facilitate synchronization of various parts. Plug-in products are smaller in size and need to be prefabricated in two parts for splicing and welding. The components themselves have a certain curvature. If the welding is improper, the crystal oscillator may easily deform due to stress, resulting in reduced product airtightness and product stability, which will affect the normal operation of the circuit. The working environment of the crystal oscillator has high requirements for cleanliness. The welding environment is a vacuum environment, and the thickness of the weld needs to be precisely controlled during cold pressure welding. The precision requirements are high, the welding difficulty is relatively large, and the tooling requirements are high.

[0003] The components of plug-in crystal oscillators are small in size, and the welding air tightness requirements are high. They are assembled and welded using prefabricated parts. The traditional method of welding crystal oscillators has a low yield rate, poor crystal oscillator stability, and high labor intensity for workers. Utility Model Content

[0004] In view of this, the utility model aims to propose a plug-in crystal oscillator cold pressure welding mold and a welding robot to solve the problems of low yield rate of crystal oscillators, poor stability of crystal oscillators and high labor intensity of workers in traditional welding methods.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A plug-in crystal oscillator cold pressure welding mold comprises a base, a lower mold base, a lower mold, an upper mold, an upper mold base and a guide column, wherein the lower mold base is installed on the base, the lower mold is connected to the lower mold base, the lower end surface of the upper mold is fitted with the upper end surface of the lower mold, an upper mold base is installed above the upper mold, the upper mold base and the upper mold are both slidably installed on the guide column, the upper mold cutting edge cross-section is a trapezoidal cross-section, and the lower mold cross-section is a uniform cross-section.

[0007] Furthermore, a T-block is symmetrically installed above the upper die seat, and the T-block is connected to the press.

[0008] Furthermore, the base is connected to the lower die base via a first hexagon socket bolt.

[0009] Furthermore, the T-block is connected to the upper die base via a second hexagon socket bolt.

[0010] Furthermore, the upper die is connected to the upper die base via a semicircular head screw.

[0011] Furthermore, a top die mechanism is provided in the lower die base.

[0012] Furthermore, the top die mechanism includes a spring and a push rod, one end of the push rod is installed in the lower die seat, and the other end passes through the lower die for matching connection, and the spring is installed at the lower end of the push rod.

[0013] A welding robot comprises a plug-in type crystal oscillator cold pressure welding mold.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model adopts a single-mode structure. Compared with the multi-grinding structure, the single-mode structure can cooperate with the manipulator to load and unload materials to realize automated production.

[0016] 2. The mold of the single-mode structure of the utility model can be placed in a vacuum working environment with the robot. Compared with the multi-mode structure that can only partially place a device in a vacuum environment, the processed crystal oscillator structure has fewer tiny particles and impurities, and the working stability of the crystal oscillator is better.

[0017] 3. The cross section of the upper die cutting edge of the utility model is a trapezoidal structure with a small draft angle, and the lower die is a uniform cross-section structure. During the mold closing process, the plug-in board and the shell of the crystal oscillator can be aligned to avoid eccentricity between the two and a decrease in air tightness.

[0018] 4. After the cutting edge of the mold of the utility model is worn out, the same thickness of material can be removed from the cutting edge and the top surface of the upper mold for mold repair. After multiple mold repairs, the crystal oscillator welding effect is consistent with the dimensional accuracy before mold repair, which greatly extends the service life of the mold and reduces costs.

[0019] 5. The utility model can easily realize the positioning and clamping of the prefabricated crystal oscillator, and can conveniently perform automatic position adjustment. The operation is simple and convenient, safe and reliable, and the production efficiency is improved and the production cost is reduced.

[0020] 6. The utility model adopts a mode of compatible connection with the welding robot connection module, which can realize the automatic welding function of the crystal oscillator. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely explain the technical solutions in the embodiments of the utility model. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0027] The crystal oscillator includes two parts: a shell and a plug-in board assembly. The shell of the crystal oscillator is turned over and placed in the hole of the lower mold base 2. At the same time, the plug-in board of the crystal oscillator is placed on the crystal oscillator shell, and the flange edge of the crystal oscillator shell is fitted with the plug-in board of the crystal oscillator. The cutting edge section of the upper mold 5 is a trapezoidal section, and the section of the lower mold 4 is a uniform section structure. Combined with the cutting edge section of the upper mold 5, it can play a role in automatic centering and positioning to ensure that the crystal oscillator shell and the plug-in board are not eccentric. At this time, the upper mold 5 is pressurized to allow the crystal oscillator shell and the plug-in to penetrate each other at the atomic level to achieve the welding effect. After welding, the upper mold 5 and the upper mold base 6 move upward along the guide column 9, and the welded crystal oscillator product is ejected out of the mold through the ejection mold mechanism, and then the workpiece is taken away to complete the processing of the crystal oscillator.

[0028] The device adopts a single-mode structure. Compared with the multi-grinding structure, the single-mode structure can cooperate with the robot for loading and unloading to realize automated production.

Compared with the multi-mode structure, only part of the device can be placed in a vacuum environment. The processed crystal oscillator structure has fewer tiny particles and impurities inside, and the working stability of the crystal oscillator is better. After the mold edge is worn out, the same thickness of material can be removed from the upper mold 5 edge and the top surface of the upper mold 5 to repair the mold. After multiple mold repairs, the processed crystal oscillator welding effect is consistent with the dimensional accuracy before mold repair, which greatly extends the service life of the mold and reduces costs.

[0029] Furthermore, the ejector mechanism includes a spring 11 and a push rod 12, one end of the push rod 12 is installed in the lower mold base 2, and the other end passes through the lower mold 4 for cooperative connection. The spring 11 is installed at the lower end of the push rod 12. After welding is completed, the upper mold 5 and the upper mold base 6 move upward along the guide column 9, and the spring 11 pushes the push rod 12 to move upward, pushing the welded crystal oscillator product out of the mold, and the processing of the crystal oscillator can be completed by cooperating with the robotic arm to take away the workpiece.
