Description

Technical Field

[0001] The invention relates to the field of FPC board laminating manufacturing, and in particular to an automatic feeding device of an FPC board laminating machine. Background Art

[0002] Flexible printed circuit (FPC) has the characteristics of high wiring density, light weight, thin thickness, good bendability, etc., and is widely used in electronic devices. In the production process of flexible circuit boards, a placement machine is needed to complete the placement of SUS, PI, PSA, and label materials. The placement machine includes: a material feeder (automatic feeding device), an FPC transmission and positioning device, a placement head, and an X-axis and Y-axis platform. The X-axis and Y-axis platforms control the movement of the FPC transmission and positioning device and the placement head. The FPC transmission and positioning device is used to transport and position the FPC board. The placement head absorbs the material from the component feeder (automatic feeding device) and places it on the FPC board of the FPC transmission and positioning device. The patch material (such as SUS, PI, PSA, labels, etc.) is usually in the form of a roll. Some rolls have a material adhesive layer (usually PET material) and a material protective separator / film on the outer layer. When the automatic feeding device feeds the material, it needs to roll up the waste material (the adhesive layer after the material is peeled off) and the material protective separator / film at the same time. The existing automatic feeding device has a poor peeling effect and poor stability. Summary of the invention

[0038] Figure 6 The figure is a schematic diagram of the working principle of the automatic feeding device of the present invention. The first loading needs to be done manually. Before loading, the feed table position adjustment mechanism 372 is adjusted to separate the feed table 241 from the stripping mechanism 220. The knurled wheel lifting control cylinder 357 controls the knurled wheel 355 to separate it from the rubber wheel 354. Specifically, first, the material roll is loaded onto the unwinding wheel 310, and the material belt P carrying the product is positioned by the stripping platform 341 through the guide transition arc 3431. The separator paper P-1 separated from the material belt P is wound onto the separator paper receiving wheel 320. When the material belt P is guided downward from the front end of the stripping platform 341, the material on it is stripped by the front end of the stripping platform 341. The waste belt P-2 without the product is guided to the rubber wheel 354 through the first guide roller 70. After the rubber wheel 354 is reversed, the waste belt P-2 passes between the knurled wheel 355 and the rubber wheel 354, and then guided to the receiving wheel 360 through the second guide roller 80; then After that, adjust the feed table position adjustment mechanism 372 to make the feed table 371 close to the stripping platform 341. At the same time, the knurled wheel lifting control cylinder 357 lifts the knurled wheel 355 upwards, so that the knurled wheel 355 is close to the rubber wheel 354 to clamp the waste belt P-2; after the equipment is started, the traction stepper motor 356 drives the rubber wheel 354 to rotate, and the material belt P is pulled forward. The first torque motor 330 drives the spacer paper receiving wheel 320 to rotate and rewind the spacer paper P-1, and the second torque motor 361 drives the receiving wheel 360 to rotate and rewind the waste material P-2. The products on the material belt P are stripped by the stripping platform 341 to the feed table 371 and wait to be picked up.

[0039] The automatic feeding device of the present invention has the following advantages:

[0040] 1. An independent torque motor is set to drive the spacer paper receiving wheel. On the one hand, when the torque motor cannot drive the spacer paper receiving wheel, that is, the spacer paper is already taut, it will stop rotating, and the tension of the torque motor can be set to suit different tension environments; on the other hand, the stability of the spacer paper receiving is improved, and the service life can be increased;

[0041] 2. Both the stripping mechanism and the feeding mechanism are equipped with adjustment mechanisms to adjust the position to suit different installation environments;

[0042] 3. The space layout between each module is reasonable and compact, which saves the space occupied by the whole machine, especially greatly saves the horizontal space, and is suitable for laminating machines with requirements on horizontal space.

[0043] 4. The unloading wheel, the paper collecting wheel and the waste wheel are driven by independent driving mechanisms respectively, which can reduce the tension of the material belt being pulled, thereby solving the problem of degeneration caused by excessive tension of the material belt, and can also solve the problem of degumming or position displacement caused by excessive tension of the material belt for smaller raw materials or raw materials with low viscosity.
