Description

Technical Field

[0001] This utility model relates to the field of semiconductor and precision electronic manufacturing technology, and in particular to a crystal spot welding machine that is easy to fix. Background Technology

[0002] Spot welding machines are high-precision welding equipment that mainly work through resistance heating and pressure welding. They generate high temperatures at the contact points of the workpieces using current, causing the metal to melt locally and then joining them under pressure, thus ensuring high stability and reliability of the welding quality. They are widely used in electronics, communications, automotive, aerospace and other fields.

[0003] In the processing of quartz crystals, electrode welding is required. Two corresponding surfaces of the quartz crystal are coated with silver as electrodes, and a lead wire is welded to each electrode and connected to the pin. Then, a package shell is added to form a quartz crystal resonator.

[0004] When performing chamfering on quartz crystals, existing spot welding machines require mechanical positioning to fix the quartz crystals on the worktable using a fixture. When processing, adjusting, or flipping the crystals, the quartz crystals must be removed from the fixtures and then clamped again. The next set of quartz crystals needs to be mechanically positioned again for welding. This makes clamping and fixing cumbersome during continuous welding processes and affects the overall processing efficiency.

[0005] Furthermore, because the quartz crystal is coated with a silver layer and fixed by a clamp, the coating is easily worn off, affecting the crystal welding quality and resulting in high processing costs.

[0006] Therefore, this application provides a crystal spot welding machine that is easy to fix to meet the requirements. Utility Model Content

[0007] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a crystal spot welding machine that is easy to fix.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A crystal spot welding machine that is easy to fix includes: a cabinet, a base, a chassis, a vacuum generator, a connecting pipe, a worktable, a baffle, a welding power source, connecting wires, a frame, a welding head, a support bracket, an extraction pipe, and a vacuum suction cup. The base is installed at the bottom of the cabinet. A chassis is installed in the middle of the inner side of the cabinet. The vacuum generator is installed inside the chassis. A connecting pipe is installed at the connection port of the vacuum generator. A worktable is provided at the top of the cabinet. An adsorption area is provided on the surface of the worktable. A baffle is installed at the rear end of the cabinet relative to the worktable. A welding power source is installed on the side of the cabinet relative to the worktable.

[0015] Preferably, the connecting pipe extends upward through the chassis to the interior of the support frame and connects to the exhaust pipe.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, a vacuum generator is used to create negative pressure in the vacuum suction cup at the bottom of the worktable, thereby firmly adsorbing the crystal on the adsorption area from the bottom. This allows for quick fixation of the crystal, enabling welding to begin along the crystal seam and improving the efficiency of crystal welding processing.

[0018] In the above scheme, the vacuum suction cup generates negative pressure and adsorbs and fixes the crystal on the surface of the adsorption area through the holes of the adsorption area. The vacuum negative pressure generated in the adsorption area passes through the uniformly adsorbed crystal, and the contact pressure is ≤0.1N, which can effectively avoid mechanical damage, ensure the crystal welding quality, and reduce the defect rate.

[0019] In the above scheme, the adsorption area of ​​the workbench is rectangular in shape and the adsorption area is distributed in a 3*4 grid. A solenoid valve is installed at the connection port between the air extraction pipe and the vacuum suction cup. The solenoid valve can control the area activated by the vacuum suction cup.
