[0041] The working principle of the above technical solution is as follows: the middle frame product 3 is placed on the middle frame carrier assembly, the middle frame carrier assembly clamps the middle frame product 3 and carries it to the bottom of the middle frame camera assembly 74, after the middle frame camera assembly 74 takes pictures of the middle frame product 3, the middle frame carrier assembly continues to carry the middle frame product 3 forward until the middle frame product 3 is moved to a preset position, the flyer labeling assembly peels off the graphite sheet 47 to the preset position below the graphite sheet camera assembly 75, the rolling manipulator absorbs the graphite sheet 47, and moves and rolls the graphite sheet 47 onto the middle frame product 3;

[0042] The graphite sheet 47 is rolled onto the middle frame product 3 by an automated device, which has the advantages of high efficiency and high precision.

[0046] Embodiment 3

[0047] like Figure 1-12 As shown, the clamping assembly includes a module mounting plate 6, the module mounting plate 6 slides on the guide rail 2, the module mounting plate 6 is threadedly connected to the screw rod, the module mounting plate 6 is fixedly connected to the mounting plate 8 through the support column 7, two film sticking platform plates 9 are fixed on the mounting plate 8, and two photoelectric switches 10 are installed on the mounting plate 8, and the upper ends of the two photoelectric switches 10 are respectively located in the grooves on the two film sticking platform plates 9;

[0048] Upper positioning blocks 11 are provided at the upper ends of the two film-sticking platform plates 9, and side positioning blocks 12 are provided at the sides of the two film-sticking platform plates 9. Four slide cylinders 13 are installed at the bottom of the mounting plate 8, wherein the output ends of the two slide cylinders 13 are connected to the side correction blocks 15 through the side connecting plates 14, and the output ends of the two slide cylinders 13 are connected to the lower correction blocks 17 through the lower connecting plates 16. A middle frame product 3 is placed on the film-sticking platform plates 9, and the upper positioning blocks 11 and the lower correction blocks 17 are respectively against the upper and lower ends of the middle frame product 3, and the side positioning blocks 12 and the side correction blocks 15 are respectively against the left and right ends of the middle frame product 3;

[0049] The working principle of the above technical solution is as follows: a plurality of protrusions are provided on the upper surface of the film-sticking platform plate 9, and the plurality of protrusions are in contact with the lower surface of the middle frame product 3. The protrusions avoid the protruding cameras and the more vulnerable parts on the lower surface of the middle frame product 3, thereby protecting the middle frame product 3 and laying the middle frame product 3 flat, so that the graphite sheet 47 can be rolled on it. Because the middle frame product 3 with the protruding camera is difficult to lay flat on a plane, the photoelectric switch 10 can detect whether the middle frame product 3 is placed on the film-sticking platform plate 9;

[0050] After placing two middle frame products 3 on two film pasting platform plates 9 respectively, the upper end of the middle frame product 3 is tightly against the upper positioning block 11, and one side of the middle frame product 3 is tightly against the side positioning block 12, and the four slide cylinders 13 are started, two of which drive the side correction block 15 to move through the side connecting plate 14, and the side correction block 15 is against the other side of the middle frame product 3.

By rotating the screw adjustment block 20, the clamping degree between the screw adjustment block 20 and the unwinding shaft fixing plate 19 can be changed, thereby changing the resistance of the unwinding shaft 18 when rotating and unwinding, and maintaining a certain tension on the graphite sheet coil 21 when unwinding.

[0057] Embodiment 6

A rotating wheel support rod is provided in the tensioning wheel 32, and the end of the rotating wheel support rod is fixed in a slide groove 33 through two nuts. The slide groove 33 is provided on the side wall of the housing 23, and a protective plate 24 is fixed to the side of the housing 23.

[0059] The inner wall of the housing 23 is fixedly connected to one end of a fixing rod 34, and the inner wall of the housing 23 is fixedly connected to one end of an inner limiting rod 36. The other ends of the fixing rod 34 and the inner limiting rod 36 are fixedly connected via a supporting pad 35. The outer side of the inner limiting rod 36 is rotatably connected to a guide shaft 37. The fixing rod 34 is provided with a photoelectric sensor 38 and an optical fiber amplifier 39.

[0060] The working principle of the above technical solution is: by loosening the two nuts, the wheel support rod can be moved in the slide slot 33, driving the tensioning wheel 32 to move with the wheel support rod, thereby changing the tension of the belt 30. After the adjustment is completed, the nuts are tightened again to fix the wheel support rod in the slide slot 33;

[0061] The protection plate 24 has a certain safety protection effect on the pulley 1 27, the chain 28, the pulley 29, the belt 30 and the tensioning wheel 32 to prevent accidental contact;

The winding support plate 40 is flush with the upper surface of the dial plate 41, and adsorption holes are provided in the winding support plate 40 and the dial plate 41.

[0066] The working principle of the above technical solution is as follows: the screw in the adjustment hole 43 is loosened, and the adjustment block 42 can be fine-tuned to the left or right, thereby changing the size of the gap between the front end of the dial plate 41 and the dial platform 48, so that the graphite sheet coil 21 can pass through the gap after unwinding, and the graphite sheet 47 is left at a preset position on the dial platform 48. After the adjustment is completed, the screw is tightened again, thereby fixing the adjustment block 42 to the outside of the housing 23, thereby fixing the position of the dial plate 41;

[0067] The two limit bars 44 can make the graphite sheet coil 21 move forward on the dial plate 41 between the two limit bars 44, so as to prevent the graphite sheet coil 21 from deviating during the unwinding process, and further prevent the peeled graphite sheet 47 from deviating, so that the rolling robot cannot normally absorb the graphite sheet 47. The upper pressing plate 46 makes the graphite sheet coil 21 close to the front end of the dial plate 41 after unwinding, so as to prevent the rear end from warping when peeling the graphite sheet 47, thereby affecting the peeling effect of the graphite sheet 47.

[0068] Both the winding support plate 40 and the marking plate 41 are provided with adsorption holes, which are connected to a vacuum pump through a vacuum tube. The vacuum pump can generate negative pressure in the adsorption holes, so that the graphite sheet roll 21 after unwinding is always attached to the winding support plate 40 and the marking plate 41.

Therefore, the height of the label-shifting platform 48 can be adaptively adjusted according to the graphite sheets 47 of different thicknesses and different unwinding speeds;

[0072] The inner limit rod 2 55 serves as the rotating support shaft of the guide shaft 3 56.
