[0030] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0031] like Figure 1-Figure 13 As shown, a fully automatic double-sided covering film laminating machine includes a casing 1 and two sets of laminating film cutting and pasting systems arranged on a frame 10 of the casing 1, the laminating film cutting and pasting systems include a coil supply mechanism 2, a cutting supply mechanism 3, a transfer platform 4, a visual laminating mechanism 6, a laminating turning table 7 and a loading and unloading mechanism 8; a laminating film 9 is provided on the coil supply mechanism 2, the laminating film 9 is peeled off into a peeling layer 92 and an adhesive layer 91 by a peeling plate 311 of the cutting supply mechanism 3, the peeling layer 92 is rolled up by a peeling layer winding assembly 309 of the cutting supply mechanism 3, the adhesive layer 91 is cut into blocks by a cutting knife assembly 302 of the cutting supply mechanism 3, the block adhesive layer 91 is arranged on the transfer platform 4 and is transferred by the visual laminating mechanism 6 to the surface of the sheet material arranged on the laminating turning table 7, and the loading and unloading mechanism 8 is used to supply the sheet material to the laminating turning table 7 and take away the sheet material with the adhesive layer 91 pasted on both the front and back sides.

[0032] The present invention provides adhesive layer 91 blocks for both sides of the sheet material through two sets of laminating and cutting systems. The double-sided pasting action of the sheet material is completed alternately, and the turning over of the sheet material is achieved by the right-angle flipping of two sets of laminating and flipping tables 7. The entire pasting rhythm is compact and efficient, and the visual laminating mechanism 6 has high positioning accuracy when the adhesive layer 91 blocks are pasted with the sheet material, and the finished product pasting effect is good. Under the visual inspection action of the visual laminating mechanism 6, the quality of semi-finished products and finished products can be inspected, and the loading and unloading mechanism 8 collects and classifies the finished products according to the inspection results, and the qualified rate of the obtained finished products is guaranteed.

[0033] like Figure 1 and Figure 5 As shown, the film laminating machine also includes a traction mechanism 5, which is movably arranged on a side of the transfer platform 4 away from the cutting and supplying mechanism 3, and is used to assist the cutting and supplying mechanism 3 to evenly place the block adhesive layer 91 onto the transfer platform 4. The traction mechanism 5 includes a traction drive module 51, a clamping drive 52 and a traction splint 53. The traction drive module 51 is installed on the traction station 111 of the frame 10, which is arranged on the outside of the transfer platform 4. The clamping drive 52 is installed at the output end of the traction drive module 51, and the traction splint 53 is installed at the output end of the clamping drive 52.

[0034] If the traction mechanism 5 is not added, the cut block adhesive layer 91 needs to be retracted by the cutting and supplying mechanism 3 before it can be transferred to the transfer platform 4, which places high requirements on the movement ability of the cutting and supplying mechanism 3. In addition, if the area of ​​the block adhesive layer 91 is large, the adhesive layer 91 is prone to wrinkle and deform in the process of falling to the transfer platform 4 by the rapid retraction of the cutting and supplying mechanism 3. After the traction mechanism 5 is added, the process of the block adhesive layer 91 falling to the transfer platform 4 is changed. Specifically, after the laminating film 9 is peeled off, the traction splint 53 clamps the adhesive layer 91 and pulls it to fall on the transfer platform 4, so that the flat state of the block adhesive layer 91 is maintained.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the coil supply mechanism 2 includes a roller frame 21, a material unwinding drive 22, an unwinding tensioning assembly 23 and a material pressing roller group 24.

A double material coiling station can be set on the roller frame 21 to improve the efficiency of coil replacement. The unwinding tensioning assembly 23 can be selected in the form of gravity tensioning. The material pressing roller group 24 includes a heating roller and a cylinder for adjusting the position of the heating roller. The heating roller heats the coating film 9 to improve the peeling effect of the coating film 9.

[0036] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the cutting and supplying mechanism 3 is arranged on the coil supplying station 102, and the cutting and supplying mechanism 3 includes a cutting knife group 302, a stripping plate 311, a stripping layer winding assembly 309 and a visual positioning unit 303. The visual positioning unit 303 and the cutting knife group 302 are installed on the frame 10 through the cutting frame 301, and the stripping plate 311 is movably arranged on the frame 10 through the feeding rail 306. The visual positioning unit 303 is used to monitor the position of the pasting film 9, and the cutting knife group 302 is used to cut the adhesive layer 91 of the pasting film 9 into pieces; the cutting knife group 302 cuts the adhesive layer 91 of the pasting film 9 by driving the cutting knife with a motion module. The cutting and supplying mechanism 3 uses the cutting knife group 302 to complete the cutting of the pasting film 9, and when the stripping plate 311 retreats along the feeding rail 306, the pasting film 9 is stripped.

[0037] The cutting and feeding mechanism 3 also includes:

[0038] The layered pressing roller 305 is installed on the cutting frame 301 through the pressing and positioning module 304, and is used to press the cutting marks; when the adhesive layer 91 is pulled by the traction mechanism 5, the layered pressing roller 305 can reduce the movement of the laminating film 9 caused by the low synchronization accuracy of the traction mechanism 5 and the peeling plate 311;

[0039] The winding and positioning roller group 312, the cutting and pressing roller group 307 and the winding and tensioning assembly 308 are provided. The winding and positioning roller group 312 is a mechanism in which a cylinder installed on the peeling plate 311 drives the roller shaft to move, and is used to reverse the peeling layer 92, and the reversing position is adjustable; the cutting and pressing roller group 307 and the winding and tensioning assembly 308 are both installed on the winding station 103, and are used to assist the peeling layer winding assembly 309 in winding the peeling layer 92, and the winding and tensioning assembly 308 uses a gravity roller shaft to tension the peeling layer 92;

[0040] The ion blower 310 , whose output end is matched with the peeling plate 311 , is used to eliminate static electricity on the separation line of the adhesive layer 91 and the peeling layer 92 .

The silicon steel carrier 43 is used to carry the adhesive layer 91 cut by the cutting and supplying mechanism 3. The positioning component 41 is a vertical motion module. The transfer platform 4 can make way for the traction mechanism 5 and the cutting and supplying mechanism 3 when receiving the adhesive layer 91 by moving up and down, and is as close to the adhesive layer 91 as possible to reduce the amplitude of its downward swing. The silicon steel carrier 43 needs to be subjected to bonding weakening treatment to reduce the adhesion between the adhesive layer 91 and the silicon steel carrier 43.

[0042] like Figure 1 , Figure 3 and Fig. 9As shown, the visual film sticking mechanism 6 is installed on the film sticking station 105. The visual film sticking mechanism 6 includes a film sticking guide rail 61, a film sticking frame 62, a grabbing drive module 63, a rotating drive module 64 and an adsorption material grabber 65.

The grabbing drive module 63 is installed on the film sticking frame 62. The adsorption material grabber 65 is installed at the output end of the grabbing drive module 63. The film sticking frame 62 is also equipped with a visual module for pasting positioning. Under the action of the positioning visual module, the adsorption material grabber 65 realizes three-dimensional movement through the grabbing drive module 63. With the action of the rotating drive module 64, the adsorption material grabber 65 can realize the compensation of the difference in the relative position between the adhesive layer 91 and the plate, and can realize high-precision laminating action.
