Technical Field

[0001] The present invention relates to the technical field of bonding wire processing, and particularly to a bonding wire double-sided dispensing device and process. Background Art

[0002] In the production process of a display screen, dispensing treatment needs to be performed on the display screen. In current automated production, an automated dispensing machine is used in combination with a manipulator for automatic loading and unloading dispensing operations.

After the front-side dispensing equipment finishes processing, it needs to be manually transferred to the back-side dispensing equipment for continued processing to complete the dispensing treatment. The dispensing alignment is mainly achieved through fixture positioning. Therefore, the current dispensing equipment has a relatively low production efficiency for manual loading and unloading, a relatively low accuracy of the dispensing position, and poor production stability.

The front dispensing moving and positioning component 45 drives the front dispensing head to move according to the front dispensing path. During the movement, the front dispensing head 44 dispenses glue on the front surface of the workpiece 27 located at the front dispensing station 28. During the dispensing process, the first conveying moving component cooperates with the front dispensing path to control the movement of the workpiece 27 to the corresponding point positions. When operating continuously, these point positions are connected into line positions. The first conveying device 2 transports the workpiece 27 that has been dispensed with glue to the first flipping station 29 of the first flipping device 4 to complete the front dispensing process of the workpiece 27.

[0065] In the dispensing surface switching step, the first flipping device 4 vacuum adsorbs and grabs the front surface of the workpiece 27 located at the first flipping station 29 and is flipped to the second feeding station 53 of the second feeding device 5 by the first flipping driving component 54 to complete the dispensing surface switching process of the workpiece 27.

[0066] In the back dispensing feeding step, the second feeding device 5 vacuum adsorbs and grabs the back surface of the workpiece 27 located at the second feeding station 53 and transports it to the third feeding station 59 of the second conveying device 6. The second conveying device 6 vacuum adsorbs and grabs the front surface of the workpiece 27 located at the third feeding station 59 and transports it to the back dispensing station 62 by the second conveying moving component to complete the back dispensing feeding process.

[0067] In the backside dispensing step, the backside dispensing device 7 captures the backside marker point image at the current position of the workpiece 27 through the backside dispensing CCD camera and outputs the current position data. The backside dispensing path is output by comparing the current position data with the preset position data. The backside dispensing moving and positioning component drives the backside dispensing head to move according to the backside dispensing path. During the movement, the backside dispensing head dispenses glue on the backside of the workpiece 27 located at the backside dispensing station 62. The second conveying device 6 transports the workpiece 27 after glue dispensing to the second flipping station 63 of the second flipping device 8 to complete the backside glue dispensing process of the workpiece 27.

[0068] In the preliminary blanking step, the second flipping device 8 vacuum adsorbs and grabs the backside of the workpiece 27 located at the second flipping station 63 through the second flipping and picking component 68 and is driven by the second flipping driving component 67 to flip to the first blanking station 66 of the blanking device 9 to complete the preliminary blanking process.

[0069] In the blanking step, the blanking device 9 vacuum adsorbs and grabs the front side of the workpiece 27 located at the first blanking station 66 through the blanking and picking component 72 and is driven by the blanking moving component 71 to transport it to the second blanking station 52 for blanking to complete the blanking process.
