Detailed ways

The present invention will be described in further detail below in conjunction with specific embodiments.

Example:

As shown in Figures 1 and 2, an automatic assembly machine for LGA products includes a material shifting component 1, a mechanical loading component 2 positioned at the front end of the material shifting component 1, an unloading track 9a positioned at the end of the material moving component 1 and The material shifting assembly 1 is arranged equidistantly in sequence according to the same station distance. Component 4b, third pressing component 5c, turning component 8, third film sticking component 4c, fourth pressing component 5d and second tearing film component 6b. Before assembly, the LGA base material is stacked in the material tray, and the material tray is stacked by the worker on the mechanical loading component 2. The mechanical loading component 2 will put the LGA substrates one by one on the material transfer component 1, and the material transfer component 1 It will take the LGA base material and pass through the first film assembly 4a, the first pressing assembly 5a, the first tearing film assembly 6a, the bushing assembly 7, the second pressing assembly 5b, the second film assembly 4b, the third Pressing component 5c, flipping component 8, third film sticking component 4c, fourth pressing component 5d and second tearing film component 6b. The steps to go through are:

① Paste A glue: the first film sticking component 4a sticks the A film on the front of the LGA substrate, the A film and the LGA substrate are pressed tightly by the first pressing component 5a, and then the back of the A film is pressed by the first tearing film component 6a. The film is torn off, leaving the A glue layer;

②Installation of the bushing: the bushing assembly 7 installs the bushing on the part of the A glue layer, and then the second pressing component 5b compresses the bushing and the LGA base material;

③Apply B glue: the second film assembly 4b pastes the B film on the front of the LGA substrate, and the third pressing assembly 5c compresses the B film and the LGA substrate;

④ Flipping: the LGA substrate is flipped over by the flipping component 8 so that the reverse side is up;

⑤Pasting C glue: the third film sticking component 4c sticks the C film on the reverse side of the LGA base material, the C film and the LGA base material are pressed tightly by the fourth pressing component 5d, and then the back of the C film is pressed by the second tearing film component 6b. The film is torn off, leaving the C glue layer;

⑥Packing: After the LGA base material with the C adhesive layer has reached the end of the material transfer component 1, it slides along the unloading track 9a to the manual adhesive area, and the worker manually tears off the B film, leaving the B film layer, and then puts the LGA The base material is folded in half, so that the B adhesive layer and the C adhesive layer are docked to complete the assembly.

This assembly machine is used to quickly and efficiently complete the bushing and gluing steps of LGA products, with a high degree of automation and a reliable pass rate.

As shown in Figures 2 to 4, the material shifting assembly 1 includes a servo motor 11, a chain 12 driven by the servo motor 11, and carrier plates 13 equidistantly arranged on the chain 12, and the distance between adjacent carrier plates 13 is equal to bit distance. The carrier board 13 is used to place the LGA base material, and the loading board 13 is driven by the servo motor 11 to bring the LGA base material to each station to complete the operation steps.

As shown in Fig. 1 to Fig. 3, a mechanical unloading assembly 9b is provided at the end of the material moving assembly 1, and the unloading position of the mechanical unloading assembly 9b is separated from the fourth pressing assembly 5d by a station distance. When there is no worker to paste B glue temporarily, the equipment can be switched to the automatic unloading mode, that is, before the LGA base material reaches the unloading track 9a, the mechanical unloading component 9b will place the LGA base material in the tray, and wait for the workers to come Switch back to the blanking track 9a blanking mode again. In this way, the equipment is prevented from shutting down due to the absence of workers, and the utilization rate of the equipment is improved.

As shown in Figures 1 to 4, a number of positioning components 3 are provided below the material transfer component 1, and these positioning components 3 correspond to the feeding position of the mechanical feeding component 2, the film sticking position of the first film sticking component 4a, the second film sticking component 4b, the film sticking position of the third film sticking assembly 4c, the installation position of the bushing assembly 7, the working position of the flipping assembly 8, and the blanking position of the mechanical blanking assembly 9b; each positioning assembly 3 includes a pair of horizontal movements The clamping block 31, the clamping block 31 can clamp the carrier board 13. Because loading, filming, bushing, flipping, and unloading require high action precision, in order to prevent the flexibility of the chain 12 from making the position of the carrier 13 unstable, the carrier 13 needs to be clamped and fixed by the clamp 31 when it stops, so that It can ensure the positioning accuracy and prevent the operating components from knocking off the LGA substrate, resulting in assembly failure.

As shown in Figure 3, the first film sticking assembly 4a, the second film sticking assembly 4b and the third film sticking assembly 4c have the same structure, and all include a manipulator 41 for transferring the film material, a film preparation device 42 for preparing the film material, and a The CCD device 43 for confirming the position of the film material, the CCD device 43 is located on the moving path of the manipulator 41 from the film preparation device 42 to the film sticking position, and the manipulator 41 will adjust the film material according to the image obtained by the CCD device 43 . The film material generally adopts tape, so it needs to be cut into a block film material suitable for the required shape on the film preparation device 42 first, and then the manipulator 41 can pick up the film material and paste it on the specific position of the LGA substrate. Because there may be errors in the position of the film material preparation, it is necessary to use the CCD device 43 for shooting and positioning first, so that the manipulator 41 can adjust the position of the film material during the moving process, so that it can be pasted accurately in place.

As shown in Figure 3, the bushing assembly 7 includes a vibrating plate 71 and a bushing device 72, and the bushing device 72 is used to install the bushing dropped from the vibrating plate 71 on the A-glue that has been pasted on the material transfer assembly 1. layer on the LGA substrate.

As shown in FIGS. 1 to 3 , the LGA product automatic assembly machine also includes a control cabinet 100 for starting and stopping the equipment, switching the blanking mode and processing speed. Workers complete various settings of the equipment through the control cabinet 100 .

As shown in FIGS. 1 to 3 , the LGA product automatic assembly machine also includes a display screen 101 for displaying equipment parameters. Through the display screen 101, workers can intuitively understand the operating status of the equipment, and can judge whether the equipment needs maintenance.

What have been described above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
