Description

Technical Field

[0001] The utility model belongs to the technical field of notebook production equipment, in particular to an ultrasonic welding device for conductive copper sheets of a notebook. Background Art

[0002] Ultrasonic welding equipment for conductive copper sheets for laptops is a special device that uses the principle of ultrasonic vibration to weld conductive copper sheets. During the manufacturing process of electronic products such as laptops, this equipment generates high-frequency vibrations through an ultrasonic generator. These vibrations are transmitted to the welding head. When the welding head contacts the conductive copper sheet, it converts the high-frequency vibration energy into heat energy, melting the metal at the interface of the copper sheet and cooling it under a certain pressure to shape it, thereby welding the conductive copper sheet to the laptop stand.

[0003] However, after the existing notebook conductive copper sheet welding equipment welds the conductive copper sheet to the notebook stand, it needs to stop and remove the notebook stand. This step is not only time-consuming, but also interrupts the continuity of the welding operation, resulting in a decrease in overall work efficiency. Secondly, the existing notebook conductive copper sheet welding equipment lacks effective monitoring of the pressure between the ultrasonic welding component and the conductive copper sheet during the welding process. If the welding pressure is too high, it may not only damage the equipment, but also affect the welding quality, resulting in a loose connection between the conductive copper sheet and the notebook stand or other welding defects.

[0004] Therefore, it is very necessary to invent a kind of notebook conductive copper sheet ultrasonic welding equipment. Utility Model Content

[0005] The purpose of the utility model is to provide an ultrasonic welding device for conductive copper sheets of a notebook to solve the problems mentioned in the background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] Furthermore, the fixing plate includes a plate body, a servo and a pressure plate, and two pressure plates are provided on one side of the plate body, wherein both ends of the pressure plate are fixed to the corresponding servo output ends, and the servo is fixed to the plate body by bolts. Such a setting facilitates clamping and fixing of the laptop stand.

[0009] Furthermore, the ultrasonic welding mechanism includes a frame, a cylinder, a slider, a pressure sensor and an ultrasonic welding assembly, the frame is slidably installed on the outer side of the support frame, and a lead screw is passed through the interior of the frame through threaded engagement; a slider is slidably installed inside the frame, wherein the upper end of the slider is fixed to the output end of the cylinder by a bolt, and the cylinder is fixed to the upper end of the frame by bolts; a pressure sensor and an ultrasonic welding assembly are respectively fixed inside the frame, wherein the input end of the pressure sensor is fitted with the upper side of the ultrasonic welding assembly; the pressure sensor is connected to an external production computer through a data cable. Such a setting can prevent the ultrasonic welding assembly from exerting excessive pressure on the conductive copper sheet on the laptop stand.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] According to the setting of the present invention, the staff only needs to fix the laptop stand on the fixed plate at one end of the chassis, and then drive the transmission shaft through the first motor to transfer the laptop stand to the bottom of the ultrasonic welding mechanism for welding. After the welding is completed, the transmission shaft is driven by the first motor again to transfer the welded laptop stand to the other end of the chassis for the staff to remove. This process greatly reduces the fixing and disassembly time of the laptop stand before and after welding, and significantly improves the overall work efficiency; secondly, when welding the conductive copper sheet on the laptop stand, the pressure sensor can detect the pressure of the ultrasonic welding component on the conductive copper sheet on the laptop stand. When it is detected that the pressure is too high, the pressure sensor will immediately send an alarm signal to the external production computer, prompting the operator to take timely measures to avoid the decline in welding quality or damage to the equipment due to excessive pressure.
