Technical Field

[0001] This utility model belongs to the field of ultrasonic welding, and specifically relates to a pneumatic quick-release structure for use in ultrasonic welding equipment. Background Technology

[0002] The ultrasonic mold used in ultrasonic welding is typically connected to the welding equipment via a mounting plate. Different welding products require different ultrasonic molds, and the ultrasonic mold must be replaced when changing welding products. However, the mounting plate used to install the ultrasonic mold is usually bolted to the frame, which hinders the quick assembly and disassembly of the ultrasonic mold, resulting in slow mold adjustment and affecting the efficiency of ultrasonic welding. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a pneumatic quick-release structure that can be applied to the connection between the mounting base plate and the frame of an ultrasonic welding equipment. This structure enables rapid assembly and disassembly of the mounting base plate, thereby facilitating the rapid replacement of the ultrasonic base mold and improving the efficiency of ultrasonic welding.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model provides a pneumatic quick-release structure, including:

[0006] The base has a movable cavity, an air inlet is provided on the side wall of the movable cavity, and the base also has a quick-release hole;

[0007] A quick-release component, wherein the quick-release component is installed in the quick-release hole;

[0008] A pneumatic actuator is disposed within the movable cavity and can move away from the air inlet under the pressure of the air pressure introduced through the air inlet.

[0009] An elastic reset member is disposed within the movable cavity and on the side of the pneumatic actuator facing away from the air inlet, for pushing the pneumatic actuator toward the side of the air inlet;

[0010] And locking components;

[0011] The quick-release hole has a through hole on its inner wall that connects the quick-release hole and the movable cavity; the quick-release component has a retaining groove on its outer wall; the pneumatic push component has an anti-air groove; and the retaining groove and the anti-air groove are connected by the through hole.

[0012] When the pneumatic pusher is positioned near the air inlet in the active cavity, the locking member disengages from the retaining groove and is accommodated in the clearance groove, and the quick-release member is released from the base.

[0013] When the pneumatic pusher is located on the side away from the air inlet in the active cavity, the locking member disengages from the anti-air groove and engages with the through hole and the retaining groove, and the quick-release member is locked to the base.

[0014] When the quick-release structure of this application is applied to an ultrasonic welding equipment, the base is installed on the welding equipment, and the quick-release component is installed on the mounting base plate where the ultrasonic bottom mold is located. Under normal conditions, through the action of the elastic reset component, the pneumatic pusher is located on the side closer to the air inlet, and the locking component is engaged in the through hole and the retaining groove, which can lock the quick-release component to the base, thereby realizing the connection between the ultrasonic bottom mold and the welding equipment. When it is necessary to replace the ultrasonic bottom mold, it is only necessary to pass gas through the air inlet, and the pneumatic pusher moves towards the side away from the air inlet through air pressure. When it moves to the corresponding position, the locking component can enter the clearance groove from the retaining groove, and the quick-release component is released from the locked state and can be taken out from the quick-release hole, thereby realizing the replacement of the ultrasonic bottom mold.

The pneumatic pusher has a clearance hole in the middle, and the pneumatic pusher is fitted onto the circular protrusion through the clearance hole. The through hole is formed on the wall of the circular protrusion, and the clearance groove and the first inclined surface are both provided on the inner wall of the clearance hole. Through the above structural design, the pneumatic pusher can be positioned using the circular protrusion, and the stability of the holding component's movement can be improved with the circular protrusion as the center.

One end of the annular outer wall is detachably fixed to the front wall, and the other end of the annular outer wall is integrally formed with the bottom wall. The circular protrusion is disposed in the middle of the front wall, and the bottom wall has an opening for avoiding the circular protrusion. The air inlet is opened on the bottom wall, and a sealed cavity is formed between the bottom wall, the pneumatic actuator, and the circular protrusion. This structural design facilitates the disassembly and assembly of the front and rear cover plates, as well as the assembly of the pneumatic actuator. It also ensures that the sealed cavity formed by the pneumatic actuator near the air inlet allows for air pressure regulation to move the pneumatic actuator.

[0021] Furthermore, a first sealing ring is provided between the outer wall of the pneumatic actuator and the annular outer wall of the rear cover plate, a second sealing ring is provided between the inner wall of the clearance hole and the outer wall of the circular protrusion, and a third sealing ring is provided between the outer wall of the circular protrusion and the inner wall of the opening. This structure ensures that a sealed cavity is formed between the bottom wall, the pneumatic actuator, and the circular protrusion, allowing the air pressure to be adjusted by introducing gas, thus propelling the pneumatic actuator within the movable cavity.

[0022] Furthermore, the elastic reset component includes a spring, the pneumatic pusher has a first guide groove on the side opposite to the air inlet, and a second guide groove is provided on the inner wall of the front cover. The first guide groove and the second guide groove are arranged opposite to each other. One end of the spring is disposed in the first guide groove, and the other end is disposed in the second guide groove. Through the above structural design, the spring can be guided and limited, improving the stability of the spring's movement.

[0023] Furthermore, the pneumatic quick-release structure also includes a positioning plate with a positioning groove, and a positioning post is provided on the outer wall of the front cover plate, the positioning post being engaged within the positioning groove.
