[0011] The right press seat is installed through a swing arm, which swings under the drive of the second cylinder to pull up the film at one end to facilitate the subsequent cutting operation.

[0012] Furthermore, a guide plate with a guide groove is installed on the swing arm.

[0013] The guide plate installed on the swing arm can be used to guide the movement of the diaphragm.

[0014] Furthermore, the cutting mechanism includes a third cylinder fixed on the rear side of the connecting plate, an "L"-shaped adapter plate is fixed on the extending rod of the third cylinder, a fourth cylinder is fixed on the adapter plate, a fixed blade is fixed to one side of the adapter plate through a connecting rod, a movable blade is movably mounted on the fixed blade through an axis, and the movable blade and the extending rod of the fourth cylinder are movably connected through an axis and a connecting rod.

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1 When the film sticking mechanism for PCB board is used, the film roll is stored on the material tray 3, and the film strip is taken out from the material tray 3, and the film strip is initially positioned after passing around the right pressing seat 5 and the left pressing seat 4. When the film sticking operation is performed, the right pressing seat 5 is first moved down to stick the film strip with the adhesive layer on the PCB board. At this time, the mounting plate 2 is driven by the slide cylinder 1 to move forward. Figure 1 The right side of the middle plate moves, and the laminated film strip moves to the bottom of the left pressure seat 4, and the left pressure seat 4 provides a pressing force. At this time, the right pressure seat 5 moves up, so that the film strip located under the right pressure seat 5 moves up, and the film strip is located above the PCB. After the lamination is completed, the cutting mechanism completes the cutting of the film strip.

[0027] At this time, one laminating operation is completed. When the next laminating operation is performed, the operation is repeated. First, the right pressing seat 5 presses the film strip to complete the initial laminating, and then the left pressing seat 4 continues to press and laminat, and the right pressing seat 5 moves up to facilitate cutting.

[0028] See also Figure 2 The left pressure seat 4 has an extended connecting plate 6 as the installation body, and the connecting plate 6 is fixed on one side of the installation plate 2. The first cylinder 7 drives the first roller 9 installed on the connecting rod 8 to contact the diaphragm to complete the diaphragm pressing operation.

[0029] The main body of the right pressure seat 5 is a swingable swing arm 10, which is movably mounted on the mounting plate 2 through an axis. Driven by the second cylinder 11, the swing arm 10 can be rotated along the axis. The second roller 12 installed at the end of the swing arm 10 is used to press the diaphragm.

[0030] In order to facilitate the guiding operation of the diaphragm, the diaphragm can pass through the guide plate 13 installed on the swing arm 10, and the guide groove in the guide plate 13 is used to guide the diaphragm.

[0031] See also Figure 3 A third cylinder 14 is installed on the rear side of the connecting plate 6. When the third cylinder 14 is working, it drives the adapter plate 15 installed with the fourth cylinder 16 to move forward and backward. A fixed blade 17 is also installed on the adapter plate 15. After the adapter plate 15 moves, the fixed blade 17 can be driven to move until cutting. At this time, the fourth cylinder 16 drives the movable blade 18 to rotate. The movable blade 18 and the fixed blade 17 are movably connected through a shaft. At the same time, the upper side of the movable blade 18 is movably connected to the connecting rod through the shaft. The connecting rod is also movably connected to the end of the extended rod of the fourth cylinder 16 through the shaft. Therefore, when the fourth cylinder 16 is working, the movable blade 18 can be started to rotate to complete the cutting operation of the diaphragm.

[0032] See also Figure 1 On the mounting plate 2, the guide wheel 19 between the material tray 3 and the swing arm 10 is located on the left side of the diaphragm to facilitate the guided movement of the diaphragm.

[0033] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;

In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0035] Finally: The above description is only a preferred implementation mode of the utility model and is not used to limit the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the utility model.
