Description

Technical Field

[0001] The invention mainly relates to the technical field of ultrasonic welding, and in particular to an ultrasonic metal welding machine. Background Art

[0002] Ultrasonic metal welding is a solid phase welding technology. During the welding process, the welding tool head (ultrasonic welding head) applies pressure and high-frequency ultrasonic vibration to the metal to be welded, causing severe friction and plastic deformation at the metal interface, thereby promoting a good connection between the interfaces.

[0003] The welding head of an ultrasonic metal welding machine often performs ultrasonic welding through high-frequency ultrasonic vibration, which causes the welding head and the product to be welded to have high temperatures and are easily adhered to each other, causing the welding head to tear the surface of the product when leaving the product, thereby affecting the essence of the product. Summary of the invention

[0004] The present invention mainly provides an ultrasonic metal welding machine to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] An ultrasonic metal welding machine comprises a workbench, the top of the workbench is connected to a welding mechanism, the bottom of the welding mechanism is provided with a supporting mechanism, and the supporting mechanism is connected to the top of the workbench;

[0007] The supporting mechanism includes a long slot arranged at the top of the workbench, a conveyor belt assembly connected to both ends of the long slot body, and a lifting assembly arranged between the two conveyor belt assemblies;

[0008] The lifting assembly includes an electric push rod connected to the inside of the workbench, and a support bar connected to the execution end of the electric push rod.

[0009] Furthermore, the conveyor belt assembly includes a support plate connected to one end of the long trough body, two transmission rollers are connected to both ends of one side of the support plate, and the two transmission rollers on the same side are connected by a conveyor belt;

[0010] A motor is connected to the surface of the support plate on one side away from the transmission roller, and the output shaft of the motor is connected to the adjacent transmission roller. In the present invention, the conveyor belt is driven to operate, and the operation of the conveyor belt drives the workpiece on the conveyor belt to move automatically, so that the workpiece can be moved to the bottom end of the ultrasonic welding head.

[0011] Furthermore, the support bar includes a support plate connected to the output end of the electric push rod, and the top of the support plate is connected to multiple springs, and the tops of the multiple springs are connected to the bar body. In the present invention, the support plate is driven to rise and fall by the electric push rod, and in this way, the bar body is driven to rise and fall. The spring is set so that the support plate will not be affected during the shaking of the bar body.

[0012] Furthermore, a groove is provided at the bottom end of the strip body, and a vibration motor is connected to the groove body. In the present invention, the vibration of the vibration motor drives the strip body to vibrate, thereby accelerating the separation between the product on the strip body and the ultrasonic welding head.

[0013] Furthermore, a heat dissipation mechanism is provided on one side of the welding mechanism, and the heat dissipation mechanism includes a support rod connected to the upper surface of the workbench, and a heat dissipation fan connected to the support rod. In the present invention, the support rod is used to provide support for the heat dissipation fan, and the airflow generated by the heat dissipation fan is used to dissipate heat between the product and the ultrasonic welding head.

[0014] Furthermore, a shift block is connected to one side of the bar body, and the shift block is used to contact the travel switch. The travel switch is connected to the inside of the workbench. In the present invention, the travel switch is driven by the shift block to monitor the position of the bar body through the travel switch, so that the controller connected to the travel switch can control the extension and retraction of the electric push rod according to the information.

[0015] Furthermore, a pressure plate is connected to the groove body of the long groove, and both ends of the pressure plate are plugged into the conveyor belt. In the present invention, the pressure plate passes through the conveyor belt and the strip body, so that when the ultrasonic welding head falls, it can provide stable support for the product, thereby further improving the welding stability of the ultrasonic welding head.

[0016] Furthermore, a long hole is provided at the top end of the strip body, and the long hole is used for the pressure plate to pass through. In the present invention, the long hole provides sufficient activity space for the pressure plate.

[0017] Furthermore, a rubber pad is connected to the top of the plate body of the pressure plate. In the present invention, the service life of the pressure plate is extended by providing the rubber pad.

[0018] Furthermore, the welding mechanism includes a cylinder connected to the upper surface of the workbench, a chassis connected to the output end of the cylinder, and an ultrasonic welding head connected to the bottom of an end of the chassis away from the cylinder. In the present invention, the chassis is driven to rise and fall by the cylinder, and the ultrasonic welding head on the chassis is raised and lowered, thereby performing ultrasonic welding processing on the product.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Firstly, the present invention drives the support bar by the electric push rod. Since the product to be welded is placed on the support bar, the product rises with the rise of the ultrasonic welding head, thereby preventing the ultrasonic welding head from leaving the product too quickly and causing tearing of the product surface.

[0021] Secondly, the present invention accommodates the vibration motor through the groove on the support bar, and the vibration of the vibration motor drives the bar body to vibrate, thereby accelerating the separation between the product on the bar body and the ultrasonic welding head.
