Description

Technical Field

[0001] This invention belongs to the field of shielding conductive film production equipment, and specifically relates to an online correction device for the production of shielding conductive film. Background Technology

[0002] Currently, conductive shielding film, also known as electronic film, is used as an electrical component in electronic products such as mobile phones, computers, and tablets (specifically in places where high-temperature heat dissipation and conductivity are required), serving to provide shielding, conductivity, light protection, moisture protection, and high-temperature resistance.

[0003] However, during the process of composite shielding conductive films, if any layer of the film shifts, it will very likely cause the conductive film to be scrapped, thereby increasing production costs.

[0004] To achieve online correction of the shielding conductive film, many correction modes have been adopted in the market. However, due to the complexity of the structure, not only is it difficult to implement the correction, but also ordinary correction devices have difficulty correcting the correction once the angle and position of the shielding conductive film change. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an improved online correction device for the production of shielding conductive film.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] An online correction device for the production of shielding conductive film includes an online monitoring unit and an online correction unit.

[0008] The online monitoring unit includes a track rod extending along the width direction of the shielding conductive film and located on one side of the front or back of the shielding conductive film; a slide block slidably mounted on the track rod; a flip arm rotatably mounted on the slide block about a center line parallel to the length direction of the track rod; a mounting base located at the end of the flip arm away from the slide block; an infrared sensing probe mounted on the mounting base; and a driver for driving the slide block to move linearly along the track rod, wherein the infrared sensing probe is perpendicular to the shielding conductive film it passes through; the online correction unit includes a correction roller attached to the back of the shielding conductive film and extending along the width direction of the shielding conductive film; a power unit for driving the correction roller to move in a left-right direction; and a control processor capable of receiving information obtained by the infrared sensing probe, wherein the shielding conductive film in contact with the correction roller moves synchronously with the correction roller, and the control processor is connected to the power unit.

[0009] Preferably, the actuator includes a lead screw extending along the length of the track rod and a drive wheel disposed at the end of the lead screw, wherein the lead screw and the slide form a transmission screw. Using a simple transmission screw to achieve linear motion not only ensures accurate distance movement but also smooth linear motion.

[0010] According to a specific embodiment and preferred aspect of the invention, the slide includes a seat body that cooperates with a lead screw, and an arm fork extending from the end of the seat body and inserted into a track rod. The use of an inserted arm fork facilitates the formation of the lead screw (i.e., restricts the rotation of the slide relative to the lead screw) and also facilitates the guidance of linear motion.

[0011] Preferably, the track rod has a circular cross-section, and the fork is U-shaped, with the diameter of the bottom of the U-shape equal to the outer diameter of the track rod. Once connected, the surfaces fit together perfectly, ensuring accurate movement.

[0012] Specifically, the track rod is located above the shielding conductive film, the slide is located above the track rod, and the fork arm is inserted into the track rod with its opening facing downwards. This layout facilitates implementation.

[0013] Furthermore, the bottom of the fork opening is located below the bottom of the track rod. This provides the best effect.

[0014] According to another specific embodiment and preferred aspect of the invention, the tilting arm is inclined from top to bottom, with its upper end rotatably mounted on the slide block via bolts, and its lower end positioned close to the shielding conductive film. The rotational adjustment of the tilting arm facilitates adjustment of the angle of the infrared sensing probe, ensuring it is perpendicular to the shielding conductive film it passes over.

[0015] Preferably, the mounting base includes a mounting panel arranged parallel to the shielding conductive film, a connecting panel for connecting the mounting panel to the flip arm, and an infrared sensing probe mounted on the mounting panel.

[0016] Preferably, the mounting panel has mounting holes extending along the width of the shielding conductive film, and the infrared sensing probe is movably mounted on the mounting holes via a connector, enabling fine-tuning.

[0017] Furthermore, the connecting panel and the mounting panel are vertically aligned, with the connecting panel fitting snugly against one side of the tilting arm. This ensures the strength of the mounting base.

[0018] According to another specific embodiment and preferred aspect of the present invention, the power unit includes a power rod arranged parallel to the correction roller and capable of moving along its own length, a first bushing and a second bushing sleeved at both ends of the correction roller, and a first connecting rod and a second connecting rod, wherein the two ends of the first connecting rod are respectively rotatably connected to one end of the first bushing and the power rod; the two ends of the second connecting rod are respectively rotatably connected to the other end of the second bushing and the power rod, and the power rod, the first connecting rod, the second connecting rod, and the correction roller form a parallelogram structure. In this way, the movement of the parallelogram not only drives the shielding conductive film to move left and right, but also pushes the correction roller forward to further tension the shielding conductive film.

[0019] Preferably, an extension rod is formed at the end of the power rod, and the power unit further includes an electromagnetic coil with the extension rod as its core, wherein the electromagnetic coil is connected to the control processor circuit. The movement of the power rod is achieved by energizing the electromagnetic coil.

[0020] Furthermore, there are two extension rods that are concentrically arranged at both ends of the power rod, and there are two corresponding electromagnetic coils with opposite current flows. This makes it easier to implement left or right correction of the shielding conductive film.

[0021] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0022] On the one hand, by adjusting the angle and position of the infrared sensing probe, this invention not only meets the online monitoring requirements for preventing deviation of the shielding conductive film edge at different angles, but also ensures that the infrared sensing probe and the shielding conductive film passing by are always in a perpendicular state, thus achieving high accuracy. On the other hand, the information fed back by the infrared sensing probe is used to achieve automatic deviation correction of the shielding conductive film by the left and right movement of the correction roller, thereby meeting production needs.

[0034] like Figure 1 As shown, the online correction device for producing shielding conductive film in this embodiment includes an online monitoring unit A and an online correction unit B.

[0035] Specifically, the online monitoring unit A includes a track rod 1 extending along the width direction of the shielding conductive film M and located on one side of the front of the shielding conductive film M, a slide block 2 slidably mounted on the track rod 1, a flip arm 3 rotatably mounted on the slide block 2 about a center line parallel to the length direction of the track rod 1, a mounting base 4 located at the end of the flip arm 3 away from the slide block 2, an infrared sensing probe 5 mounted on the mounting base 4, and a driver 6 that drives the slide block 2 to move linearly along the track rod 1, wherein the infrared sensing probe 5 is perpendicular to the shielding conductive film M that it passes through.

[0036] Specifically, the track rod 1 is located above the front side of the shielding conductive film M, and the slide 2 is located above the track rod 1.

[0037] The actuator 6 includes a lead screw 60 extending along the length of the track rod 1 and a drive wheel 61 disposed at the end of the lead screw 60, wherein the lead screw 60 and the slide 2 form a transmission screw. Using a simple transmission screw to achieve linear motion not only ensures accurate distance movement but also provides smooth linear motion.

[0038] Combination Figure 2 As shown, the slide 2 includes a seat body 20 that cooperates with the lead screw 60, and an arm fork 21 extending from the end of the seat body 20 and inserted into the track rod 1. The use of an inserted arm fork facilitates the formation of the transmission lead screw (that is, restricts the rotation of the slide relative to the lead screw), and also facilitates the guidance of linear motion.

[0039] The track rod 1 has a circular cross-section, and the fork arm 21 is U-shaped, with the diameter of the bottom of the U-shape being equal to the outer diameter of the track rod 1. Once connected, the surfaces fit together perfectly, ensuring accurate movement.

[0040] The fork arm 21 is inserted into the track rod 1 with its opening facing downwards. This layout facilitates implementation.

[0041] In this example, the bottom of the opening of the fork 21 is located below the bottom of the track rod 1. This provides the best effect.

[0042] The tilting arm 3 is tilted from top to bottom, with its upper end adjustablely mounted on the base body 20 via bolts, and its lower end positioned close to the shielding conductive film M. The tilting arm's rotation allows for easy adjustment of the infrared sensor's angle, ensuring it is perpendicular to the shielding conductive film it passes over.

[0043] In addition, the mounting base 4 includes a mounting panel 40 arranged parallel to the shielding conductive film M, a connecting panel 41 for connecting the mounting panel 40 to the flip arm 3, and an infrared sensing probe 5 mounted on the mounting panel 40.

[0044] The mounting panel 40 has mounting holes 400 extending along the width of the shielding conductive film M. The infrared sensing probe 5 is movably mounted on the mounting holes 400 via the connector 7, allowing for fine-tuning.

[0045] The connecting panel 41 and the mounting panel 40 are vertically arranged, with the connecting panel 41 attached to one side of the flip arm 3. This ensures the strength of the mounting base and also facilitates the parallel adjustment of the mounting panel 40 and the shielding conductive film M.

[0046] The online correction unit B includes a correction roller b1 that is attached to the back of the shielding conductive film M and extends along the width direction of the shielding conductive film M, a power unit b2 that drives the correction roller b1 to move in the left and right direction, and a control processor that can receive information obtained by the infrared sensing probe 5. The shielding conductive film M that is in contact with the correction roller b1 moves synchronously with the correction roller b1, and the control processor is connected to the power unit b2.

[0047] The power unit b2 includes a power rod b20 arranged parallel to the alignment roller b1 and capable of moving along its own length, a first bushing b21 and a second bushing b22 sleeved at both ends of the alignment roller b1, and a first connecting rod b23 and a second connecting rod b24. The two ends of the first connecting rod b23 are rotatably connected to the first bushing b21 and the left end of the power rod b20, respectively; the two ends of the second connecting rod b24 are rotatably connected to the second bushing b22 and the right end of the power rod b20, respectively. The power rod b20, the first connecting rod b23, the second connecting rod b24, and the alignment roller b1 form a parallelogram structure. Thus, the movement of the parallelogram not only drives the shielding conductive film to move left and right, but also pushes the alignment roller forward to further tension the shielding conductive film.

[0048] An extension rod b25 is formed at the end of the power rod b20. The power unit b2 also includes an electromagnetic coil b26 with the extension rod b25 as its core, wherein the electromagnetic coil b26 is connected to the control processor circuit. The movement of the power rod is achieved by energizing the electromagnetic coil.

[0049] In this example, there are two extension rods b25, which are concentrically located at both ends of the power rod b20. There are two corresponding electromagnetic coils b26, and the current flows in opposite directions. This makes it easier to implement left or right correction shielding conductive film.

[0050] In summary, this embodiment has the following advantages:

[0051] 1. By adjusting the angle and position of the infrared sensing probe, not only can the online monitoring of the edge of the shielding conductive film at different angles be satisfied, but it can also ensure that the infrared sensing probe is always perpendicular to the shielding conductive film it passes through, thus achieving high accuracy.

[0052] 2. With the insertion of the U-shaped arm fork, it is not only convenient to form the transmission screw (that is, to limit the rotation of the slide relative to the screw), but also convenient to guide the linear motion. In addition, with the fine adjustment of the mounting hole and the connector, the accuracy of adjusting the displacement of the external induction probe is ensured.

[0053] 3. Based on the information fed back by the external induction probe, the left and right movement of the correction roller realizes the automatic correction of the shielding conductive film, thereby meeting the production needs;

[0054] 4. During the correction process, the movement of the parallelogram not only drives the shielding conductive film to move left and right, but also pushes the correction roller forward to further tighten the shielding conductive film.

[0055] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
