Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Example 1 The existing pressure-fit film application process for semiconductor chip packaging requires a drive assembly, a nozzle, and a vacuum adsorption assembly. The drive assembly includes a servo motor and a ball screw, with the servo motor connected to the nozzle via the ball screw to drive the nozzle's movement. The vacuum adsorption assembly includes a vacuum generator, which is connected to the internal channel of the nozzle to allow the nozzle to adsorb the film. This pressure-fit film application mechanism occupies a large space and has a complex structure.

[0027] In view of this, see Figures 1 to 4 The coating device for a powder compression molding and packaging system provided in this embodiment of the present invention includes a frame 100, a first driving member 200, a first support member 300, a second driving member 400, a second support plate 500, and a film clamping assembly 600. The first driving member 200 is mounted on the frame 100 and is convectively connected to the first support member 300 to drive the first support member 300 to rise and fall. The second driving member 400 is mounted on the first support member 300 and is convectively connected to the second support plate 500 to drive the second support plate 500 to rise and fall. The film clamping assembly 600 includes a sealing plate 610, a third driving member 620, and a clamping plate 630. The sealing plate 610 is fixedly mounted on the second support plate 500, and the third driving member 620 is mounted on the second support plate 500 and convectively connected to the clamping plate 630 to drive the clamping plate 630 to move toward or away from the sealing plate 610.

[0028] The first drive component 200 is mounted on the frame 100, which supports the first drive component 200. The first drive component 200 is connected to the first support component 300 to drive the first support component 300 to rise and fall. Since the second drive component 400 is mounted on the first support component 300, when the first support component 300 rises and falls, it can drive the second drive component 400, the second support plate 500 connected to the second drive component 400, and the film clamping assembly 600 to rise and fall together, thereby achieving coarse adjustment of the position of the film clamping assembly 600.

[0029] The second driving component 400 is installed on the first support component 300, and the first support component 300 supports the second driving component 400. The second driving component 400 is connected to the second support plate 500 to drive the second support plate 500 to rise and fall. Because the sealing plate 610 and the third driving component 620 are installed on the second support plate 500, when the second support plate 500 rises and falls, the sealing plate 610, the third driving component 620 and the clamping plate 630 connected to the third driving component 620 can rise and fall together to achieve fine adjustment of the position of the membrane clamping assembly 600.

[0030] The third driving member 620 is mounted on the second support plate 500, and the second support plate 500 supports the third driving member 620. The third driving member 620 is connected to the clamping plate 630 to drive the clamping plate 630 to move towards the sealing plate 610 to clamp the film; or, the clamping plate 630 moves away from the sealing plate 610 to release the film.

[0031] The following are the steps for using the coating device for a powder compression molding packaging system: First drive unit 200 and second drive unit 400 are activated sequentially to lower the film clamping assembly 600 to the film pickup position; third drive unit 620 is activated to bring the sealing plate 610 and clamping plate 630 close to the film; a cutting device, used in conjunction with the coating device for the powder compression molding packaging system, cuts the film; first drive unit 200 and second drive unit 400 are activated to raise the film clamping assembly 600, moving it away from the cutting area of ​​the cutting device; a transfer device, used in conjunction with the coating device for the powder compression molding packaging system, transfers the chip to below the film; first drive unit 200 and second drive unit 400 are activated to lower the film clamping assembly 600; third drive unit 620 is activated to separate the sealing plate 610 and clamping plate 630, releasing the film; first drive unit 200 and second drive unit 400 are activated to reset the film clamping assembly 600.

[0032] The first driving component 200 and the second driving component 400 cooperate to move the film clamping assembly 600 to a suitable height. Then, the third driving component 620 drives the clamping plate 630 to approach the sealing plate 610 to clamp the film and pull it out to achieve the purpose of film coating. This film coating device for powder compression molding and packaging system can realize film pressing and film coating, which is simple to operate, improves work efficiency, and reduces the number of parts to reduce the space occupied.

[0033] The following is a detailed description of the structure of the coating device used in a powder compression molding and packaging system: In the optional embodiment of this utility model, a sealing strip 611 is installed on the surface of the sealing plate 610 opposite to the clamping plate 630.

The surface roughness of the sealing strips 611 is higher than that of the sealing plate 610.

[0035] The sealing strip 611 increases the clamping force of the sealing plate 610 and the clamping plate 630 on the film, preventing the film from detaching.

[0036] In the optional embodiment of this utility model, the sealing strip 611 is embedded in the sealing plate 610.

[0040] Specifically, in the use of the coating device for the powder compression molding and packaging system, the second support plate 500 is placed horizontally, and the sealing plate 610 is installed on the bottom plate of the second support plate 500, extending downwards and placed vertically. The clamping plate 630 is generally L-shaped, and the connecting block 631 is connected to the third driving member 620. The clamping block 632 is opposite to the bottom wall of the sealing plate 610. When the third driving member 620 drives the connecting plate to rise or fall, the clamping block 632 moves closer to or away from the bottom wall of the sealing plate 610. In this embodiment, the third driving member 620 is installed on the top surface of the second support plate 500, and the clamping block 632 is located below the sealing plate 610. Therefore, when the third driving member 620 drives the connecting block 631 to rise, the clamping block 632 moves closer to the bottom wall of the sealing plate 610 to clamp the film; when the third driving member 620 drives the connecting block 631 to fall, the clamping block 632 moves away from the bottom wall of the sealing plate 610 to release the film.

[0041] The clamping plate 630 is L-shaped, and the clamping plate 630 can be raised and lowered by the third driving component 620 so that the clamping plate 630 can cooperate with the sealing plate 610 to clamp or release the film.

[0042] In the optional embodiment of this utility model, the membrane clamping assembly 600 further includes a transmission plate 640, which is perpendicularly connected to the end of the connecting block 631 away from the clamping block 632, and the transmission plate 640 is opposite to the second support plate 500.

[0046] Specifically, the number of first guide structures 650 can be set according to actual needs.

[0047] The first guide structure 650 is used to guide the movement direction of the transmission plate 640, and in turn guide the movement direction of the clamping plate 630, so as to achieve precise control of the movement direction of the clamping plate 630 and avoid deviation.

[0049] Specifically, the axes of both the bearing housing and the guide shaft are set in the vertical direction.

[0050] When the transmission plate 640 moves up and down relative to the second support plate 500, the guide shaft slides along the bearing seat, which guides the movement of the transmission plate 640.

A first driving member 200 is mounted on the fixed plate 110 and connected to the first lifting plate 310 to drive the first lifting plate 310 to rise and fall. A second lifting plate 320 is disposed perpendicular to the first lifting plate 310, forming an installation area between the first lifting plate 310 and the second lifting plate 320. The second driving member 400 is located within the installation area, saving space. The first lifting plate 310 and the second lifting plate 320 are connected by screws or integrally formed.

[0053] The first lifting plate 310 and the second lifting plate 320 are vertically connected, which reduces the space occupied by the entire coating device for the powder compression molding and packaging system.

[0054] In the optional solution provided by the embodiments of this utility model, the first driving member 200, the second driving member 400 and the third driving member 620 are all configured as cylinders.
