The three-axis automatic dispensing equipment 2 includes a dispensing equipment base 2.1, which is a square frame formed by overlapping and welding profiles. A three-axis module 2.2 is set on the top of the dispensing equipment base 2.1. The three-axis module 2.2 can be either a pneumatic cylinder or an electric cylinder. A pneumatic spraying valve 2.3 is fixed on the telescopic end of the three-axis module 2.2. The pneumatic spraying valve 2.3 is existing technology and is used for spraying glue. The pneumatic spraying valve 2.3 is set above the double-layer conveyor line 1 and is configured to dispense glue to the power module on the double-layer conveyor line 1. The automatic pressing device 3 includes a pressing device base 3.1, which is a square frame formed by overlapping and welding profiles. A telescopic power mechanism 3.2 is provided on the top of the pressing device base 3.1. The telescopic power mechanism 3.2 is a cylinder. A pressing head 3.3 is fixedly provided on the power output end of the telescopic power mechanism 3.2. The pressing head 3.3 can be a plate-shaped structure, and its shape and size can be selected according to the usage requirements. The pressing head 3.3 is located above the double-layer conveyor line 1 and at the end of the three-axis automatic dispensing device 2, thereby pressing the power module after dispensing. The visual inspection device 4 includes an inspection device base 4.1. An image capture component is installed on the top of the inspection device base 4.1. The image capture component is located above the double-layer conveyor line 1 and downstream of the automatic pressing device 3. The image capture component includes a planar intelligent camera 4.2. The model of the planar intelligent camera 4.2 can be selected according to the usage requirements. The lens of the planar intelligent camera 4.2 faces the top of the belt conveyor line 1.1.

[0016] The automatic adhesive application equipment for power modules in Example 1 operates on the following principle: 1. Feeding and conveying: The power module workpiece can be placed on top of the double-layer conveyor line 1 by a robot arm, or the power module can be placed at the bottom of the double-layer conveyor line 1 by a robot arm to buffer the power module, and then lifted to the top of the double-layer conveyor line 1 by elevator I 1.2 or elevator II 1.3 for subsequent processing. 2. Adhesive application station: Positioning and triggering: When the carrier carrying the workpiece moves to the preset working position directly below the three-axis automatic dispensing equipment 2, it can be detected by the photoelectric sensor or limit switch installed at the station. The signal is then sent to the central control equipment, such as the PLC. This method is existing technology, so its specific principle and method will not be described in detail here.

[0017] Glue application: After receiving the signal, the central control equipment, such as the PLC, starts working according to the preset program instructions of the three-axis automatic glue dispensing equipment 2. The three-axis module 2.2 moves according to the pre-programmed path, driving the pneumatic glue spray valve 2.3 to complete the precise and uniform glue application operation to the power module.

[0018] Completion and Feedback: After the glue application process is completed, the glue dispensing equipment sends a "job completed" signal to the PLC.

[0019] 3. Pressing station: Flow and triggering: After receiving the glue application completion signal, the central control equipment such as PLC instructs the double-layer conveyor line 1 to send the workpiece to the next station. When the workpiece arrives at the pressing station below the automatic pressing equipment, the sensor at that station will also detect and trigger the signal.

[0020] Pressing: The PLC controls the telescopic power mechanism 3.2 to move, driving the pressure head 3.3 downward to apply pressure to the glued power module, ensuring that the components are firmly attached. The pressing time is controlled by the PLC program. After pressing is completed, the cylinder resets and sends a completion signal back to the PLC.

[0021] 4. Testing station: Positioning and Imaging: The conveyor line delivers the pressed workpiece to the visual inspection device 4. Once in position, the central control device, such as the PLC, triggers the visual inspection device 4, turning on the ring light source to provide optimal lighting conditions for the workpiece. The planar intelligent camera 4.2 simultaneously acquires high-definition images of the adhesive application area.

[0022] Image analysis and judgment: The planar intelligent camera 4.2 transmits the acquired images to its internal or connected image processing system. The system compares and analyzes the real-time images with preset acceptance standards, such as whether the adhesive line is continuous or whether there is any overflow. The analysis and judgment standards can be customized according to different process acceptance requirements.
