Description

Technical Field

[0001] The utility model relates to the technical field of electronic watches, in particular to a cooling device for welding electronic watch patches. Background Art

[0002] Before assembling an electronic watch, the patch welding tooling is an essential step, and after the patch is accurately welded to the motherboard, the staff uses the corresponding cooling device to cool the workpiece.

[0003] When the cooling devices on the market are used to cool the motherboard, if the self-cleaning function is not set, the soldered patches are extremely susceptible to dust and are not easy to remove later. In addition, during the cooling process, the rapid cooling method will affect the overall structural stability of the workpiece after welding, and in severe cases will cause cracks and deformation of the workpiece.

[0004] The prior art publication number is CN211352656U, which provides a technical solution: a cooling device for motherboard patch welding, comprising a supporting frame, an embedded groove and a protective pad, wherein an installation frame is fixed to the internal top end of the supporting frame, and a transverse rod is welded inside the installation frame, a fan is installed in the middle of the transverse rod, and the embedded groove is arranged inside the installation frame by casting, and a cooling pipe is embedded inside the embedded groove. In the utility model, by setting connecting support rods, vertical rods and cleaning brushes, before the operation of conveying and cooling is performed, when the workpiece is disturbed by dust, the device takes the vertical rod as the support base point under the connection and cooperation of the connecting support rods, and under the surface-to-surface fitting setting, the device uses the extrusion force and the clearing force generated between the cleaning brush and the conveyor belt in the transmission process to effectively clean the dust on the surface of the conveyor belt, thereby effectively reducing the interference of dust factors on the post-welding forming of the workpiece.

[0005] but:

[0006] The device is manually controlled to pull the installation frame carrying the entire cooling component, and slides up or down along the track set inside the slide groove through the pulley until the device slows down the diffusion rate of the cold air by virtue of the change in height difference during the sliding process, while ensuring that the cooling operation of the workpiece is under a reasonable temperature condition. However, it cannot dissipate heat during welding and needs to be used after welding. In addition, the heat dissipation is poorly targeted and the heat source cannot be dissipated in time.
