Description

Technical Field

[0001] The present application relates to the technical field of functional sheet manufacturing, and in particular to a double-sided ACF adhesive device for functional sheets. Background Art

[0002] Gluing is a common process in many industries, primarily used to enhance product adhesion, protect surfaces, or achieve specific functional requirements. While traditional single-sided gluing machines are widely used on production lines, their single operating mode results in low efficiency. This is particularly true for products requiring double-sided gluing, which often requires two machines or two separate operations. This not only increases costs but also prolongs production cycles.

[0003] Currently, the functional sheets on the market need to be double-sidedly pasted with ACF glue. The edge of the functional sheet has two first rows of pins set at intervals, both of which include front and back sides. When pasting, the ACF adhesive layer of the tape is pasted on the first front side of one first row of pins. The staff flips the functional sheet over and continues to paste the second back side of the other first row of pins, or after pasting the second front side of the second row of pins, manually flips the sheet over and continues to paste the first back side of the first row of pins. Then the ACF adhesive layer is connected to the FPC through hot pressing. However, this method wastes human resources and has low efficiency. Utility Model Content

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-8 The double-sided ACF adhesive device for the functional sheet provided in this application is further described in detail.

[0041] Example 1

[0042] See also Figure 1-8 The double-sided ACF adhesive device 1 for functional sheets provided in an embodiment of the present application includes a carrier 11, two pressing components 12, four adhesive supply components 13 and a control system.

[0043] like Figures 1 to 2 As shown, the supporting platform 11 includes a supporting plate 111 and a plurality of side plates 112 arranged on the side of the supporting plate 111. The supporting plate 111 includes a mounting surface 1111 and a back surface 1112 arranged opposite to each other. The supporting plate 111 is penetrated by a through opening 1113 along the width direction of the supporting platform 11.

[0044] The support plate 111 may include a first support plate 1115 and a second support plate 1116. The first support plate 1115 is nested within the second support plate 1116. The gap between the first support plate 1115 and the second support plate 1116 forms a through-hole 1113. The first support plate 1115 and the second support plate 1116 are both connected to a plurality of side plates 112. Moving the second support plate 1116 can control the size of the through-hole 1113. Both the first support plate 1115 and the second support plate 1116 are made of stainless steel, offering excellent corrosion resistance and strength.

[0045] like Figure 3 As shown, two pressing assemblies 12 are both disposed on the mounting surface 1111 and are symmetrically arranged on either side of the through-opening 1113 along the length of the carrier 11. Each pressing assembly 12 includes a pressing block 121 and a first driving member 122. The first driving member 122 is disposed at one end of the pressing block 121 away from the through-opening 1113. The first driving member 122 is electrically connected to the control system and is capable of causing the pressing blocks 121 located on either side of the through-opening 1113 to move toward the through-opening 1113 simultaneously.

[0046] Specifically, the two pressing components 12 are respectively arranged on the first support plate 1115 and the second support plate 1116, so that the pressing component 12 can press the ACF adhesive layer attached to the tape 14 to the front and back sides of the functional sheet 17. The pressing block 121 is made of high-strength aluminum alloy and has good wear resistance and lightweight characteristics. The contact surface of the pressing block 121 is non-planar to reduce the contact area with the tape 14 and prevent the ACF adhesive layer from adhering to the pressing block 121. The ACF adhesive layer attached to the tape 14 is a conductive adhesive, so that the ACF adhesive layer attached to the functional sheet 17 can be connected to the FPC. The first driving member 122 can be a hydraulic cylinder, which can provide greater driving force to ensure the stable movement of the pressing block 121. A first sliding member 123 is further provided at one end of the pressure block 121, which is adjacent to the mounting surface 1111. The mounting surface 1111 is also provided with a second sliding member 1114. The first sliding member 123 and the second sliding member 1114 cooperate to enable the pressure block 121 to slide. One of the first sliding member 123 and the second sliding member 1114 can be a rail, and the other can be a slot. In this embodiment, the first sliding member 123 is a slot, and the second sliding member 1114 is a guide rail. These provide a low coefficient of friction, ensuring smooth movement of the pressure block 121.

[0047] The four glue supply components 13 are all arranged on the mounting surface 1111 and each glue supply component 13 is located on both sides of a pressing component 12 along the width direction of the supporting platform 11. Each glue supply component 13 includes a material tray 131 for providing tape 14, a tensioning component 132 for adjusting the tension of the tape 14, and a material receiving component 133 for collecting waste tape 14. The material trays 131 are respectively located at the four vertices of the first square and the diagonally arranged material trays 131 are a group. The tensioning components 132 are respectively located at the four vertices of the second square and the two diagonally arranged tensioning components 132 are a group. A material receiving component 133 is respectively set at the positions of the four vertices around the through-hole 1113, and the material receiving components 133 at the diagonal positions are a group.

[0048] like Figures 4 and 5As shown, specifically, two glue supply assemblies 13 are arranged on one side of the through-opening 1113, and another two glue supply assemblies 13 are arranged on the other side of the through-opening 1113. The two glue supply assemblies 13 are located on both sides of a pressing assembly 12 along the width direction of the support platform 11. The tensioning assembly 132 includes a round rod 1321, a roller 1322, and an abutment 1323. The material tray 131, round rod 1321, and roller 1322 are arranged on the mounting surface 1111 in a direction close to the through-opening 1113, and are all circular. The material tray 131 is used to store more adhesive tape 14 and is rotatable. The round rod 1321 is used to more accurately guide the movement of the adhesive tape 14. The round rod 1321 can be connected to a motor on the back 1112, and the control system is connected to the motor. The roller 1322 is used to better assist in the transportation of the adhesive tape 14 and ensure that the adhesive tape 14 can be parallel to the through-opening 1113, facilitating the pressing of the adhesive tape 14 by the pressing block 121. The abutment 1323 is provided on the side of the round rod 1321 away from the pressing assembly 12 and can move toward the round rod 1321. The abutment 1323 is made of polyurethane and has a lower friction coefficient. The abutment 1323 may also include a motor. The control system controls the abutment 1323 to abut against the round rod 1321, thereby pressing the tape 14. In this embodiment, the material tray 131 on the first support plate 1115, which is located on one side of the pressing assembly 12, is provided with the tape 14. After passing through the round rod 1321 and the roller 1322, the tape 14 is located above the through-hole 1113, then passes through the roller 1322 on the other side and is pressed by the round rod 1321 and the abutment 1323 on the other side. The control system controls the rotation of the round rod 1321 on the other side to move the tape 14, thereby more precisely controlling the travel distance of the tape 14. On the second support plate 1116 The material tray 131 with the tape 14 and the material tray 131 with the tape 14 on the first support plate 1115 are not on the same side along the length direction of the carrier platform 11, but the control system controls the rotation of the round rod 1321 so that the rotation directions of the tapes 14 on both sides of the through-hole 1113 are the same, so that the ACF adhesive layers of the two tapes 14 are respectively applied to the first front side 171 and the second back side 174 or the second front side 173 and the first back side 172 of the functional sheet 17, and then the ACF adhesive layer is connected to the FPC through hot pressing.

[0049] The control system can also have self-diagnosis and remote monitoring functions, which can detect and report abnormal conditions in a timely manner to ensure the reliable operation of the equipment.

[0050] The material receiving member 133 is disposed on the mounting surface 1111 and is located on the side of the roller 1322 away from the pressing assembly 12. Specifically, after the ACF layer of the tape 14 is applied to the functional sheet 17, the used tape 14 is compressed and transmitted by the round rod 1321 and the abutment member 1323, and then enters the material receiving member 133 for easy recycling. In this embodiment, the material receiving member 133 may include a vacuum generator and a vacuum hole. The vacuum generator draws air from the material receiving member 133 to generate negative pressure, thereby easily sucking waste material through the vacuum hole and placing it into a trash can below through an internal pipe.

[0051] like Figures 6 to 8 As shown, the double-sided ACF adhesive device 1 for a functional sheet is placed vertically during normal operation. The double-sided ACF adhesive device 1 for a functional sheet may further include a shearing assembly 15. A connecting plate 1121 is provided between the opposing side plates 112. The shearing assembly 15 is disposed on the connecting plate 1121 and is movable on the connecting plate 1121. Specifically, the shearing assembly 15 includes a second driving member 151 and a shearing member 152. The second driving member 151 is disposed on the connecting plate 1121. The shearing member 152 is disposed at one end of the second driving member 151 facing the support plate 111. The shearing member 152 can be opened to allow the ACF adhesive layer of the adhesive tape 14 to extend therethrough, and then the shearing member 152 can be closed to shear the ACF adhesive layer. In this embodiment, the shearing member 152 includes a movable block 1521 and a fixed block 1522. The end of the movable block 1521 facing the support plate 111 is provided with a wedge-shaped surface 1523, and the end of the fixed block 1522 proximal to the movable block 1521 is provided with a blade 1524. The second driving member 151 may be a solenoid valve with a fast response speed, capable of quickly responding to commands issued by the control system. This solenoid valve not only controls the movement of the shearing member 152 on the connecting plate 1121, positioning the shearing member 152 on the side of the material tray 131 provided with the adhesive tape 14, but also controls the movement of the shearing member 152 toward the through-hole 1113, thereby opening and closing the movable block 1521 and the fixed block 1522, thereby cutting the ACF layer of the adhesive tape 14 into small sections for easier application and minimal waste. Both the movable block 1521 and the fixed block 1522 of the shearing member 152 are made of tungsten carbide, which offers enhanced hardness and wear resistance. The inclined surface design of the movable block 1521 makes it easier for the ACF adhesive layer to enter between the movable block 1521 and the fixed block 1522 and be cut by the blade 1524. The blade 1524 of the fixed block 1522 is sharp and has a good cutting effect, ensuring that the ACF adhesive layer is completely cut off.

[0052] The separation component 16 includes a moving part 161 and a separation part 162. The moving part 161 is arranged on the back side 1112, and the separation part 162 is arranged on the mounting surface 1111. The moving part 161 passes through the mounting surface 1111 and is connected to the separation part 162 and drives the separation part 162 to move the separation tape 14 and the ACF layer. The separation part 162 can be a separation needle or a separation sheet.

[0053] In this embodiment, moving member 161 is a conveyor belt mechanism. Controlling its rotation through a control system allows for smoother control of the speed and travel of separator 162. Separator 162 is positioned on the side of material tray 131 where tape 14 is absent. After pressure block 121 applies the ACF adhesive layer of tape 14 to functional sheet 17, the control system directs separator 162 to move horizontally along through-hole 1113 toward material tray 131 where tape 14 is present, separating the tape 14 from the ACF adhesive layer. Separator 162 is a needle, which reduces contact area with the ACF adhesive layer, preventing the ACF adhesive layer from adhering to the needle and causing waste.

[0054] The support platform 11 may also include a control box 18, which is located at the vertical upper end of the first support plate 1115. The control box 18 may include a control switch, a temperature controller, and a speed regulator. For example, when using the double-sided adhesive laminating device, since different products require different temperatures, it is necessary to manually adjust the temperature through the thermostat. This not only allows for intuitive viewing of the real-time temperature but also facilitates adjustment. The control switch is used to control whether heating is enabled; heating occurs only when the control switch is turned on. The speed regulator can adjust the heating speed to improve efficiency.

[0055] The implementation principle of this embodiment is as follows: the double-sided ACF adhesive device 1 of the functional sheet realizes an efficient double-sided adhesive function. First, the functional sheet 17 is horizontally placed in the through-hole 1113, and the material trays 131 of the same group on the first support plate 1115 and the second support plate 1116 are placed with the adhesive tape 14. The control system starts and simultaneously controls the round rod 1321 and the abutment 1323 on the same side of the material tray 131 without the adhesive tape 14 to press the adhesive tape 14. The control system accurately controls the rotation speed and angle of the round rod 1321 to control the travel distance of the adhesive tape 14. The adhesive tape 14 moves horizontally to the top of the through-hole 1113 through the multiple rollers 1322 on one side of the through-hole 1113, and the ACF on the adhesive tape 14 is simultaneously pressed by the pressing blocks 121 respectively provided on the first support plate 1115 and the second support plate 1116. The CF adhesive layer is pressed against the functional sheet 17. Driven by the second drive member 151, the movable block 1521 and the fixed block 1522 move toward the through-hole 1113 and open. The ACF adhesive layer of the adhesive tape 14 extends between the movable block 1521 and the fixed block 1522. The movable block 1521 and the fixed block 1522 then close, and the blade 1524 completely cuts the ACF adhesive layer. The movable block 1521 and the fixed block 1522 then move back to their original position. The separation needle, driven by the conveyor mechanism, moves between the adhesive tape 14 and the ACF adhesive layer, separating the two. The pressing block 121 and the separation needle are then reset, and the used adhesive tape 14 is moved and sent to the receiving unit 133 for recycling. The entire process is highly automated, significantly improving the accuracy and efficiency of adhesive application, significantly reducing the cost of manual operation, and improving production efficiency and product quality.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
