Feeding structure of wearable COF roll material

Abstract

The feeding structure of the wearable COF coil stock comprises a wearable COF coil stock device and a feeding device, the wearable COF winding device comprises a winding drum, winding paper and a COF; the roll paper is wound on the winding drum, and the COF is arranged on the roll paper; the surface of a section of the roll paper is not provided with the COF. According to the feeding structure of the wearable COF roll material, a COF chip is not arranged on the paper body, close to one side of the winding drum, of the roll paper by one meter, and a base material is directly used, so that when one roll is used up, the paper body can be directly pulled out by one meter behind to be connected with a new roll material through an adhesive tape. In this way, material loss of the COF chip is avoided, so that the material loss can be reduced or eliminated for each roll according to the design, the efficiency is improved, and the cost is reduced.

Technical Field

[0001] The utility model relates to the technical field of wearable COF coils, in particular to a material supply structure of wearable COF coils. Background Art

[0002] At present, with the continuous advancement of science and technology, the concept of intelligence has received more and more attention. With the continuous development of modern technology, intelligence can be seen everywhere in people's lives, and smart wearable products have been very popular in recent years, such as smart watches, smart bracelets, etc. The display screens used in smart bracelets or watches are AMOLED (Active-matrix organic light-emitting diode) screens (a display technology, the full name is active matrix organic light-emitting diode panel), and AMOLED screens are generally used with COF (material, often called chip on film) structures. The existing COF (Chip On Flex, or, Chip On Film) comes in rolls, so after one roll is completed, the next roll needs to be replaced. The last 1 meter generally has a certain loss, and at most all of it is scrapped, and at least there are more than a dozen grains of loss. Each replacement of the next roll will cost about 100-700 yuan. Utility Model Content

[0006] In one embodiment, the width of the front side of the roll paper is greater than the width of the front side of the COF.

[0007] In one embodiment, the COF is arranged horizontally and equidistantly at the center of the front side of the roll.

[0008] In one embodiment, the width of the front side of the roll matches the width of the front side of the roll paper, and the roll is a hollow cylinder.

[0009] In one of the embodiments, the length of the side of the roll of paper where the COF is not provided is one meter, and the side of the roll of paper where the COF is not provided is close to the roll.

[0010] In one embodiment, a rubber strip is disposed on one side of the roll paper where the COF is not disposed and on one end close to the roll.

[0011] In one embodiment, the distances between the COFs on the roll of paper are the same, and the distances between the COFs are between 0.5 mm and 0.7 mm.

[0014] In one embodiment, the diameter of the roll is matched to the diameter of the rotating shaft of the roll feeding machine.

[0015] Compared with the prior art, the utility model has at least the following advantages:

[0016] The material feeding structure of the wearable COF roll material of the utility model does not set the COF chip on the paper body of one meter on the side of the roll close to the reel, and directly uses the base material. In this way, when a roll is used up, the remaining 1 meter can be directly pulled out and connected to the new roll material with tape. In this way, there will be no loss of COF chip material. Therefore, each roll according to the above design can reduce or eliminate material loss, improve efficiency, and reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-2 As shown, a material incoming structure of a wearable COF roll material comprises: a wearable COF roll material device 1; the wearable COF roll material device 1 comprises a reel 11, a roll paper 12 and a COF 13; the roll paper 12 is rolled on the reel 11, and the COF 13 is arranged on the roll paper 12; and there is a section of the surface of the roll paper 12 where the COF 13 is not arranged. It should be noted that the base material is directly used at the position of the roll paper 12 where the COF 13 is not arranged, so no loss will be caused when the next roll is replaced.

[0025] like Figure 1-2 As shown, in one embodiment, the width of the front side of the paper roll 12 is greater than the width of the front side of the COF 13. The COF 13 is arranged horizontally and equidistantly in the center of the front side of the paper roll 12. It should be noted that this design can facilitate the roll-up feeding device to remove or install the COF 13 on the paper roll 12.

[0026] like Figure 1-2 As shown, in one embodiment, the width of the front side of the reel 11 matches the width of the front side of the paper roll 12, and the reel 11 is a hollow cylinder. The diameter of the reel 11 matches the diameter of the rotating shaft of the roll feeding machine. It should be noted that this design allows the roll feeding device to drive the reel 11 to select, thereby winding or unwinding the paper roll 12.

[0027] like Figure 1-2 As shown in the figure, in one embodiment, the length of the side of the roll paper 12 without the COF 13 is one meter, and the side of the roll paper 12 without the COF 13 is close to the reel 11. It should be noted that this design allows the rear 1 meter to be directly pulled out when a roll of wearable COF material is used up and connected to the new roll material with tape, so that there will be no problem of COF 13 material loss.

[0028] like Figure 1-2 As shown, in one embodiment, the side of the roll paper 12 is not provided with COF 13 and a rubber strip is provided on the end close to the reel 11. It should be noted that this design facilitates the staff to fix one end of the roll paper 12 on the reel 11, thereby facilitating the reeling.

[0029] like Figure 1-2 As shown, in one embodiment, the distances between COFs 13 on the roll paper 12 are the same, and the distances between COFs 13 are between 0.5 mm and 0.7 mm. It should be noted that this design allows a certain distance between COFs 13, thereby preventing them from being damaged by mutual friction when being rolled up.

[0030] like Figure 1-2 As shown, in one embodiment, the thickness of the roll paper 12 is between 0.3 mm and 0.5 mm. A smooth oil film is provided on the surface of the roll paper 12, and a plurality of patches are provided on the surface of the roll paper 12, and the shape and size of the front of the patch match the shape and size of the front of the COF 13. It should be noted that this design can prevent the roll paper 12 from being easily damaged, so that it is convenient to recycle and reuse, and it is convenient to bond the COF 13.
