Description

Technical Field

[0001] The utility model relates to the field of ACF transportation, in particular to a guide wheel adjustment mechanism and an automatic attaching machine. Background Art

[0002] In the related art, automatic laminating machines used for attaching ACF (Anisotropic Conductive Film) need to use guide wheels to guide the ACF roll. The guide wheels limit the axial movement of the ACF roll along the guide wheels through their own limiting surfaces, thereby ensuring that the roll can be transported stably. In order to meet the transportation needs of ACF rolls of different widths in production, workers need to adjust the position of the guide wheel's limiting surface using measuring tools such as calipers. However, the calipers will scratch the limiting surface during the measurement process, making the limiting surface uneven and affecting the limiting accuracy of the guide wheel.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0041] Please refer to Figure 1 and Figure 2 As shown, the utility model proposes a guide wheel adjustment mechanism for conveying ACF roll materials, including a guide shaft 100 and a guide wheel 200, the guide shaft 100 includes a shaft body 110 and a limiting portion 120, the limiting portion 120 is connected to the shaft body 110 and protrudes relative to the radial surface of the shaft body 110, and the limiting portion 120 has a first limiting surface 121; the guide wheel 200 is threadedly connected to the shaft body 110, and also has a second limiting surface 210, the first limiting surface 121 and the second limiting surface 210 are arranged opposite to each other and are used to limit the axial movement of the ACF roll material along the shaft body 110; the guide wheel 200 can move along the axial direction of the shaft body 110 during rotation to make the first limiting surface 121 approach or move away from the second limiting surface 210.

[0042] The first limiting surface 121 and the second limiting surface 210 are used to limit the movement of the coil along the axial direction of the shaft body 110; Figure 1 and Figure 2As shown, in some embodiments, the first limiting surface 121, the second limiting surface 210, and the circumferential surface of the shaft body 110 jointly form a groove. When the ACF roll is conveyed using the guide wheel adjustment mechanism, the surface of the ACF roll in the thickness direction is in contact with the circumferential surface of the shaft body 110. The first limiting surface 121 and the second limiting surface 210 can contact the ACF roll when the ACF roll deviates along its width direction, thereby limiting further deviation of the ACF roll as a whole in its width direction. Because the guide wheel 200 can move axially along the shaft body 110 during rotation, the second limiting surface 210 of the guide wheel 200 and the first limiting surface 121 of the limiting portion 120 can move away from and toward each other. Therefore, the operator can adjust the distance between the first limiting surface 121 and the second limiting surface 210 by rotating the guide wheel 200 to accommodate ACF rolls of different specifications.

[0043] The present invention also provides indicator marks on the limiting portion 120 and the guide wheel 200 .

[0044] One of the specific solutions is that the surface of the limiting portion 120 has multiple first indicator marks 122, and the surface of the guide wheel 200 has at least one second indicator mark 220; the second indicator mark 220 rotates synchronously with the guide wheel 200; when the guide wheel 200 rotates relative to the shaft 110, the first indicator mark 122 can be aligned with different second indicator marks 220.

[0045] Through the above solution, when rotating the guide wheel 200, the staff can observe the phenomenon that the second indicator mark 220 changes from being aligned with one first indicator mark 122 to being aligned with another first indicator mark 122, thereby determining the degree of rotation of the guide wheel 200 relative to the shaft body 110. Since the guide wheel 200 is threadedly connected to the shaft body 110, the degree of rotation of the guide wheel 200 relative to the shaft body 110 is proportional to the distance the guide wheel 200 moves axially along the shaft body 110. Therefore, the staff can also determine the distance the guide wheel 200 is closer to or farther from the limit portion 120 based on the degree of rotation of the guide wheel 200 relative to the shaft body 110. Therefore, the staff can directly understand the distance the guide wheel 200 is closer to or farther from the limit portion 120 during rotation based on the alignment of the second indicator mark 220 with different first indicator marks 122, and can then directly adjust the distance between the first limit surface 121 and the second limit surface 210, thereby reducing the need for measuring tools.

[0046] Another solution is, please refer to Figure 1As shown, the limiting portion 120 has at least one first indicator mark 122, and the guide wheel 200 has multiple second indicator marks 220; the second indicator mark 220 rotates synchronously with the guide wheel 200; when the guide wheel 200 rotates relative to the shaft 110, the second indicator mark 220 can be aligned with different first indicator marks 122.

[0047] Through the above solution, when rotating the guide wheel 200, the staff can observe the phenomenon that the first indicator mark 122 changes from being aligned with one second indicator mark 220 to being aligned with another second indicator mark 220, and thus determine the degree of rotation of the guide wheel 200 relative to the shaft body 110. Since the guide wheel 200 is threadedly connected to the shaft body 110, the degree of rotation of the guide wheel 200 relative to the shaft body 110 is proportional to the distance the guide wheel 200 moves axially along the shaft body 110. Therefore, the staff can also determine the distance the guide wheel 200 is closer to or farther from the limit portion 120 based on the degree of rotation of the guide wheel 200 relative to the shaft body 110. Therefore, the staff can directly understand the distance the guide wheel 200 is closer to or farther from the limit portion 120 during rotation based on the alignment of the first indicator mark 122 and different second indicator marks 220, and can then directly adjust the distance between the first limit surface 121 and the second limit surface 210, reducing the need for measuring tools.

[0048] Both of the above-mentioned solutions can reduce the use of measuring tools, thereby avoiding scratches on the first limit surface 121 or the second limit surface 210 when using measuring tools to adjust the first limit surface 121 and the second limit surface 210, and avoiding affecting the limiting accuracy of the first limit surface 121 and the second limit surface 210.

[0049] It should be noted that when the limiting portion 120 has multiple first indicator marks 122, the staff can directly understand the distance that the guide wheel 200 is close to or away from the limiting portion 120 during rotation through the alignment of the second indicator mark 220 and different first indicator marks 122; in some embodiments, the first indicator mark 122 can be arranged in the circumferential direction, so as to facilitate the staff to judge whether the second indicator mark 220 is aligned with different first indicator marks 122; technical personnel in this field can adjust the circumferential spacing of different first indicator marks 122 according to actual needs.

[0050] As a preferred embodiment, multiple first indicator marks 122 are evenly distributed on the circumference of the shaft body 110; the multiple first indicator marks 122 evenly distributed on the circumference and the line connecting the axis of the shaft body 110 divide 360° into the same angle. By rotating the guide wheel 200, the second indicator mark 220 is aligned from one first indicator mark 122 to the adjacent first indicator mark 122, and the guide wheel 200 always rotates the same angle relative to the shaft body 110; and because the guide wheel 200 is threadedly connected to the shaft body 110, when the guide wheel 200 rotates the same angle relative to the shaft body 110, the guide wheel 200 can always be close to or away from the limit portion 120 by a distance corresponding to the rotation angle; the above scheme can make it easier for staff to confirm the degree of rotation of the guide wheel 200 relative to the shaft body 110.

[0051] Through the above description, those skilled in the art can understand the technical effect of the guide wheel 200 having multiple second indicator marks 220 and the multiple second indicator marks 220 being evenly distributed in the circumferential direction of the shaft body 110, which will not be repeated here.

[0052] Without departing from the inventive concept of the present invention, the guide wheel adjustment mechanism of the present invention can be used to guide other coils.

[0053] Without departing from the inventive concept of the present invention, the present invention does not limit the specific shape and alignment of the indicator mark; in some embodiments, please refer to Figure 1 As shown, the first indicator mark 122 is an arrow mark formed by engraving, painting, machining, or other technical means, and the second indicator mark 220 is a straight line segment formed by engraving, painting, machining, or other technical means. The straight line segment lengths of each second indicator mark 220 may be different. When the arrow mark points to a straight line segment, it means that the first indicator mark 122 is aligned with the second indicator mark 220 pointed to by the first indicator mark 122. In other embodiments, the first indicator mark 122 is a straight line segment formed by engraving, painting, machining, or other technical means, the guide wheel 200 has a polygonal structure, and the second indicator mark 220 is an edge on the guide wheel 200. The straight line segment and the edge are both parallel to the axis of the shaft body 110. The edge, the straight line segment, and the axis are coplanar, which means that the first indicator mark 122 is aligned with the second indicator mark 220 corresponding to the edge. In other embodiments, the first indicator mark 122 and the second indicator mark 220 can also be set as points, polygons, etc. When the projections of the first indicator mark 122 and the second indicator mark 220 in the axial direction of the shaft body 110 at least partially overlap, it means that the first indicator mark 122 and the second indicator mark 220 are aligned.

[0054] Through the description of the above embodiments and the prior art, those skilled in the art can combine the indicator marks of different shapes and confirm the alignment form of the first indicator mark 122 and the second indicator mark 220 according to actual conditions. The above combinations are all within the scope of protection of the present invention.

[0055] Furthermore, in some embodiments, the position-limiting portion 120 includes a third indicator mark and a plurality of first indicator marks 122. The fourth indicator mark 230 is disposed on one side of a first indicator mark 122 in the axial direction of the shaft 110. The first indicator mark 122 and the third indicator mark can rotate synchronously with the guide wheel 200. When the guide wheel 200 rotates relative to the shaft 110, the third indicator mark rotates relative to the second indicator mark 220. Through the above scheme, the third indicator mark can mark a first indicator mark 122, thereby providing visual guidance to the operator when rotating the guide wheel 200. For example, since the second indicator mark 220 and the first indicator mark 122 marked by the third indicator mark will only align once during one rotation, the operator can determine the number of rotations of the guide wheel 200 relative to the shaft 110 by observing the number of times the second indicator mark 220 aligns with the third indicator mark. The third indicator mark can also remind the operator of the starting position of the guide wheel 200, thereby reducing the situation where the guide wheel 200 is rotated incompletely or over-rotated.

[0056] In other embodiments, please refer to Figure 1 As shown, the guide wheel 200 has a fourth indicator mark 230 (eg Figure 1 The figure 200 is formed by engraving, painting, machining and other technical means) and multiple second indicator marks 220, the multiple second indicator marks 220 are evenly distributed on the circumference of the shaft body 110, and the fourth indicator mark 230 is set on one side of the second indicator mark 220 in the axial direction of the shaft body 110. The second indicator mark 220 and the fourth indicator mark 230 can rotate synchronously with the guide wheel 200; when the guide wheel 200 rotates relative to the shaft body 110, the second indicator mark 220 rotates relative to the fourth indicator mark 230.

[0057] Without departing from the inventive concept of the present invention, a fifth indicator mark, a sixth indicator mark, etc. may be provided to mark different first indicator marks 122 or second indicator marks 220 to further serve as a visual guide; for example, please refer to Figure 1As shown, the guide wheel 200 also has a fifth indicator mark and a sixth indicator mark. The fifth indicator mark is in the shape of the number 5 formed by engraving, painting, machining, or other technical means; the sixth indicator mark is in the shape of the number 10 formed by engraving, painting, machining, or other technical means. The fourth indicator mark 230, the fifth indicator mark, and the sixth indicator mark are set as numbers, and the numbers directly correspond to the distance the guide wheel 200 has moved axially along the shaft body 110, so that the operator can determine the axial distance of the guide wheel 200 along the shaft body 110 by reading.

[0058] For further information, please refer to Figure 1 As shown, in some embodiments, the limiting portion 120 has a first observation surface 123, which is arranged on the circumference of the shaft body 110, and the first indicator mark 122 is arranged on the first observation surface 123; alternatively, the first indicator mark 122 is arranged on the side away from the guide wheel 200; the guide wheel 200 has a second observation surface 240, which is arranged on the circumference of the shaft body 110, and the second indicator mark 220 is arranged on the second observation surface 240. Through the above solution, the staff can see the first indicator mark 122 and the second indicator mark 220 at the same time, which facilitates the staff to confirm the alignment of the first indicator mark 122 and the second indicator mark 220 when rotating the guide wheel 200.

[0059] Furthermore, in some embodiments, when the guide wheel 200 approaches the limiting portion 120 to the extreme position, a first indicator mark 122 and a second indicator mark 220 are aligned. When the guide wheel 200 is at the extreme position, the guide wheel 200 can no longer approach the limit portion 120; through the above scheme, the mutually aligned first indicator mark 122 and the second indicator mark 220 can prompt the staff that the guide wheel 200 has been rotated to the extreme position; on the other hand, the distance between the guide wheel 200 and the limit portion 120 is always the same when it is at the extreme position. When the staff rotates the guide wheel 200 from the extreme position so that the guide wheel 200 is away from the limit portion 120, the actual distance between the current guide wheel 200 and the limit portion 120 can be obtained based on the distance between the guide wheel 200 at the extreme position and the limit portion 120, combined with the alignment of the first indicator mark 122 and different second indicator marks 220 during the rotation of the guide wheel 200, or the alignment of the second indicator mark 220 and different first indicator marks 122, so that the distance between the first limit surface 121 and the second limit surface 210 can be directly adjusted according to the width specification of the ACF roll.

[0060] On the basis of the above embodiment, when the limit portion 120 has multiple first indicator marks 122, a third indicator mark can be set on the axial side of the shaft body 110 of the aligned first indicator mark 122, or when the guide wheel 200 has multiple second indicator marks 220, a fourth indicator mark 230 can be set on the axial side of the shaft body 110 of the aligned second indicator mark 220; the above scheme further reminds the staff that it has been rotated to the extreme position, reducing the situation where the staff mistakenly believes that the guide wheel 200 is at the extreme position when the first indicator mark 122 and the second indicator mark 220 are aligned.

[0061] Furthermore, in some embodiments, the guide wheel adjustment mechanism further includes a fastener 300, which can limit the axial movement of the guide wheel 200 along the shaft body 110. Those skilled in the art can use the fastener 300 to limit the axial movement of the guide wheel 200 relative to the shaft body 110 to prevent the guide wheel 200 from moving during operation, thereby ensuring stable conveyance of the ACF coil during operation of the guide wheel adjustment mechanism.

[0062] In some embodiments, the fastener 300 can be inserted into the guide wheel 200 and the shaft body 110 in a direction perpendicular to the axis of the shaft body 110 , thereby limiting the relative movement of the guide wheel 200 and the shaft body 110 along the axial direction of the shaft body 110 .

[0063] As a preferred option, please refer to Figure 3 and Figure 4 As shown, the fastener 300 is threadedly connected to the shaft body 110. The fastener 300 can move axially along the shaft body 110 during rotation and abut against one side of the guide wheel 200 on the axial direction of the shaft body 110. When the fastener 300 abuts against one side of the guide wheel 200 on the shaft body 110, an axial supporting force is generated between the fastener 300 and the guide wheel 200. This supporting force can increase the friction force on the internal thread of the guide wheel 200, thereby making it less likely for the guide wheel 200 to slide relative to the shaft body 110, thereby allowing the guide wheel 200 to be fixed at a certain position on the shaft body 110 and preventing the guide wheel 200 from moving during operation. When it is necessary to fix the guide wheel 200, a person skilled in the art can first use their hands or a special tool to fix the position of the guide wheel 200 on the shaft body 110, and then rotate the fastener 300 so that the fastener 300 approaches and finally abuts the guide wheel 200, and then release the hand or remove the special tool.

[0064] For further information, please refer to Figure 3 and Figure 4In some embodiments, the guide wheel adjustment mechanism further includes a main shaft 400, to which the guide shaft 100 is rotatably connected. The axis of rotation of the guide shaft 100 relative to the main shaft 400 coincides with the axis of the shaft body 110. With this arrangement, during operation, as the ACF roll passes over the surface of the shaft body 110 under the guidance of the guide wheel adjustment mechanism, it drives the shaft body 110 to rotate relative to the main shaft 400, reducing relative motion between the surface of the shaft body 110 and the ACF roll, thereby reducing wear on the ACF roll caused by the surface of the shaft body 110.

[0065] As a preferred solution, the guide shaft 100 is rotatably connected to the main shaft 400 via a bearing 500. The above solution can make it easier for the ACF to drive the shaft body 110 to rotate relative to the main shaft 400, further reducing the wear of the surface of the shaft body 110 on the ACF coil.

[0066] The present invention further provides an automatic attaching machine for attaching ACF rolls, the automatic attaching machine including a guide wheel adjustment mechanism as described in any of the above embodiments. Because the guide wheel adjustment mechanisms in the above embodiments can directly adjust the distance between the first limiting surface 121 and the second limiting surface 210, the positioning accuracy of the first limiting surface 121 and the second limiting surface 210 can be guaranteed, thereby enabling the ACF roll to be more stably guided by the guide wheel adjustment mechanism, and enhancing the stability of the automatic attaching machine.

[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
