Description

Technical Field

[0001] The utility model relates to the technical field of earphone processing, in particular to a spot welding table for processing earphone electronic components. Background Art

[0002] Spot welding of headphone chips is a crucial step in the headphone manufacturing process, precisely connecting the chip to the circuit board or other components to ensure proper function. Precision welding techniques, such as laser soldering, are often employed to meet the high demands for sound quality, stability, and durability.

[0003] China Utility Model Announcement No.: CN218503567U A fixing frame is fixedly installed on the top surface of the processing table, a fixing hole is provided on the top surface of the fixing frame, a cylinder is fixedly installed inside the fixing hole, a laser welding head is fixedly installed on the telescopic shaft of the cylinder, a placement plate is fixedly installed on the top surface of the processing table, a positioning plate is movably installed inside the placement plate, and a placement groove is provided on the top surface of the positioning plate; a cooling component, the cooling component is arranged on the top surface of the processing table, and is used to cool the welding chip. By setting an electric push rod, when the chip welding is completed, the staff starts the electric push rod to push the positioning plate to the bottom of the mounting frame, and then starts the air cooler to cool the chip surface. After the cooling is completed, the staff takes the chip from the placement groove to prevent the staff from being scalded by the chip that has just been spot-welded during the process of taking the chip.

[0004] The applicant found that this patent had some shortcomings in use: the spot-welded components were cooled by blowing air with a cold air blower to avoid burns, but spot welding could not be performed during the cooling process, which affected the spot welding efficiency. Moreover, the staff needed to use their fingers to pick out the components through the removal groove. Long-term operation like this would cause wear on the fingers and easily form calluses.

[0005] Therefore, the present invention designs a spot welding station for processing earphone electronic components to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the present utility model is to provide a spot welding station for processing earphone electronic components to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A spot welding station for processing earphone electronic components, comprising: a soldering station, a mounting frame is installed on the top of the soldering station, an electric cylinder is installed on one side of the top of the mounting frame, a laser welding head is provided at the output end of the electric cylinder, a turntable rotatably mounted with the soldering station is provided below the mounting frame, a rotating assembly is provided on the mounting frame, a mounting groove is provided on the other side of the top of the mounting frame, a fan is installed in the mounting groove, placement molds are installed on both sides of the top of the turntable, the two placement molds are respectively located directly below the laser welding head and the fan, a movable plate is slidably installed on the inner wall of the placement mold, a chip is placed on the top of the movable plate, an electromagnet is provided in the middle of the bottom inner wall of the placement mold, a metal block is installed in the middle of the bottom of the movable plate, and the movable plate and the placement mold are connected by a non-magnetic stainless steel spring.

[0008] Preferably, the rotating assembly includes a rotating shaft, which is rotatably mounted on the top of the mounting frame, the top of the rotating shaft is connected to the top of the driving motor, and the bottom of the rotating shaft is connected to the middle of the top of the turntable. The driving motor drives the rotating shaft to rotate 180 degrees, which can drive the turntable to rotate 180 degrees.

[0009] Preferably, rollers are installed on both sides of the bottom of the turntable, and the rollers are connected to the welding table in a rolling manner. The rotation of the turntable drives the rollers to roll on the welding table, which can reduce the friction of the turntable rotation.

[0010] Preferably, weight-reducing grooves are provided at both ends of the turntable, which reduce the weight of the turntable and facilitate the rotation of the turntable driven by the rotating shaft.

[0011] Preferably, a touch switch is installed on the side where the mold is placed, and the touch switch makes it convenient for staff to turn on and off the electromagnet.

[0012] Preferably, a rubber pad is provided on the top of the movable plate, and the rubber pad can protect the bottom of the chip.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. After the spot welding is completed, the drive motor drives the rotating shaft to rotate 180 degrees, causing the turntable to rotate 180 degrees, and the spot-welded chips are transferred to the bottom of the fan for cooling, while the chips to be spot-welded are transferred to the bottom of the laser welding head for spot welding. Spot welding and cooling are synchronized, which can improve the spot welding efficiency;

[0015] 2. After the chip of the utility model has finished cooling, the electromagnet is powered off by touching the switch, and the adsorption of the metal block is cancelled. Then, the movable plate is lifted up by the restoring force of the non-magnetic stainless steel spring, so that the chip moves upward and leaves the mold. The staff does not need to pick it up with their fingers, but can take it away directly with their hands, which reduces the situation of calluses caused by trying to pick up the chip with their fingers.
