Description

Technical Field

[0001] This invention relates to the field of ACF (Anchor Coating Film) application technology, and in particular to a release film recycling device. Background Technology

[0002] ACF (Anisotropic Conductive Film) is mainly used in the LCD panel industry. ACF tape consists of two parts: a release film and the ACF adhesive. During the bonding process, the ACF adhesive is cut into several segments and applied to the circuit board terminals to establish electrical conductivity between the circuit and the display panel. The entire bonding process requires ensuring the ACF tape is taut to guarantee bonding accuracy, while also preventing the ACF adhesive from being stretched or deformed, which would affect the bonding effect. After bonding, any remaining release film needs to be sent to a recycling center for collection.

[0003] Existing equipment typically includes a pressure roller and a roller after the ACF (Anti-Covered Film) application process. The pressure roller is pressed tightly onto the roller, and the roller is driven by a motor to rotate, thus recycling the release film. However, the contact surface between the release film and the two rollers is curved, while the motor controls the angle through which the roller rotates. Therefore, there is an error in the process of converting the angle into length, resulting in inaccurate release film recycling length. Furthermore, the tension of the ACF strip cannot be guaranteed, and improvements are urgently needed in all aspects. Summary of the Invention

[0004] Therefore, it is necessary to provide a release film recycling device that accurately controls the length of the released film and ensures the tension of the ACF strip.

[0005] This invention provides a release film recycling device, the release film recycling device comprising:

[0006] Mounting plate; and

[0007] A recycling mechanism is provided on the mounting plate. The recycling mechanism includes a moving clamping assembly and a fixed clamping assembly. The moving clamping assembly is provided with a first clamping member, and the fixed clamping assembly is provided with a second clamping member. The first clamping member and the second clamping member can open or clamp along a first direction. The first clamping member and the second clamping member are arranged along a third direction.

[0008] A drive mechanism is provided on the mounting plate, and the drive mechanism drives the motion clamping assembly to move along the third direction on the drive mechanism.

[0009] In one embodiment, the recycling mechanism further includes a guide wheel disposed on the mounting plate, the guide wheel and the second clamping member being spaced apart in the third direction.

[0010] In one embodiment, the motion clamping assembly further includes a first base plate and a first connecting plate. The first base plate is fixedly connected to the output end of the driving mechanism, the first connecting plate is fixedly connected to the first base plate, the first clamping member is disposed on the first connecting plate, and the first clamping member is connected to a first driving member to drive the first clamping member to open and clamp.

[0011] In one embodiment, the first substrate has a first strip-shaped hole extending along a second direction, and the first connecting plate is adjusted in position relative to the first substrate in the second direction through the first strip-shaped hole.

[0012] In one embodiment, the fixed clamping assembly further includes a second connecting plate, which is fixedly connected to the mounting plate. The second clamping member is disposed on the second connecting plate and is connected to a second driving member to drive the second clamping member to open and clamp.

[0013] In one embodiment, the fixed clamping assembly further includes a second substrate, a first adjusting block, and a second adjusting block. The second substrate is connected between the second connecting plate and the mounting plate, and a second strip-shaped hole extending in a second direction is formed on the side of the second substrate facing the mounting plate. The first adjusting block is disposed on the coplanar end face of the second substrate and the second connecting plate, and the position of the second connecting plate relative to the second substrate in the first direction is adjusted by the first adjusting block. The second adjusting block is connected between the mounting plate and the second substrate, and the position of the second substrate and the second connecting plate relative to the mounting plate in the second direction is adjusted by the second strip-shaped hole and the second adjusting block.

[0014] In one embodiment, the first clamping member has an initial position and a handover position. When the first clamping member is in the initial position, it is located on one side of the second clamping member in the third-order direction. When the first clamping member is in the handover position, it is located on the other side of the second clamping member in the third-order direction. The driving mechanism drives the first clamping member to switch between the initial position and the handover position.

[0015] In one embodiment, the first clamping member and the second clamping member are configured as a type of gripper, the type of gripper including two opposing clamping surfaces, the two clamping surfaces being rough planes, one of the clamping surfaces being a complete plane, and the other clamping surface being provided with a groove, the length direction of the groove being perpendicular to the third direction.

[0016] In one embodiment, the first clamping member and the second clamping member are configured as type II grippers, the type II grippers including two opposing clamping surfaces, the two clamping surfaces being planes with the same rough shape, one of the clamping surfaces having a contact surface, the contact surface being coated with a Teflon coating.

[0018] The release film recycling device provided by the present invention includes a moving clamping component and a fixed clamping component in the recycling mechanism mounted on the mounting plate for clamping and conveying the release film. The first clamping component clamps the release film. Driven by the driving mechanism, the first clamping component moves along a third direction with the release film in its clamp, passes through the middle of the open second clamping component, and reaches the junction position. The second clamping component clamps the release film, and the first clamping component releases the release film and moves back to the initial position along a third direction, so that the second clamping component passes through the middle of the open first clamping component. When the first clamping component moves to the initial position, the first clamping component clamps the release film, and the second clamping component releases the release film. The above actions are repeated continuously to realize the continuous transfer of the release film. This device uses a linear motion to clamp and feed the release film. The switching between clamping and releasing the release film by the first and second clamping components is carried out when the release film is straightened, rather than when it is relaxed. This results in higher material feeding accuracy, effectively ensuring the accuracy of the release film recovery length and keeping the release film at a stable tension, thus preventing the ACF strip from being stretched and deformed, which would affect the adhesion effect.

[0043] See Figure 1 and Figure 2 , Figure 1 The following is a schematic diagram of the structure of the release film recycling device 10 according to some embodiments of this application. Figure 2 It shows Figure 2 A magnified view of a portion of point M in the middle.

[0044] The present invention provides a release film recycling device 10, including a mounting plate 110, a recycling mechanism 120, and a driving mechanism 130. The recycling mechanism 120 is disposed on the mounting plate 110 and includes a moving clamping assembly 121 and a fixed clamping assembly 122. The moving clamping assembly 121 is provided with a first clamping member 1211, and the fixed clamping assembly 122 is provided with a second clamping member 1221. The first clamping member 1211 and the second clamping member 1221 can open or clamp along a first direction. The first clamping member 1211 and the second clamping member 1221 are arranged along a third direction. The driving mechanism 130 is disposed on the mounting plate 110 and drives the moving clamping assembly 121 to move along a third direction on the driving mechanism 130.

[0045] The release film recycling device 10 provided by the present invention includes a moving clamping component 121 and a fixed clamping component 122 in the recycling mechanism 120 mounted on the mounting plate 110 for clamping and conveying the release film. The first clamping component 1211 clamps the release film. Driven by the driving mechanism 130, the first clamping component 1211 moves along a third direction with the release film in its clamp, passes through the middle of the open second clamping component 1221, and reaches the junction position. The second clamping component 1221 clamps the release film, and the first clamping component 1211 releases the release film and moves along a third direction towards the initial position, so that the second clamping component 1221 passes through the middle of the open first clamping component 1211. When the first clamping component 1211 moves to the initial position, the first clamping component 1211 clamps the release film, and the second clamping component 1221 releases the release film. The above actions are repeated continuously to realize the continuous transfer of the release film. This device uses a linear motion to clamp and feed the release film. The switching between clamping and releasing the release film by the first clamping member 1211 and the second clamping member 1221 is carried out when the release film is straightened, rather than when it is relaxed. This has higher material feeding accuracy, effectively ensures the accuracy of the release film recovery length, and also keeps the release film at a stable tension, avoiding the ACF material strip being stretched and deformed, which would affect the adhesion effect.

[0046] In some specific embodiments, the recycling mechanism 120 also includes a guide wheel 123, which is disposed on the mounting plate 110, and the guide wheel 123 and the second clamping member 1221 are spaced apart in the third direction.

[0047] The first clamping member 1211 and the second clamping member 1221 pull the release film taut and convey it along a third direction. A guide wheel 123 is provided to guide the release film. After being guided by the guide wheel 123, the release film is sucked into a recycling pipe to prevent the release film from flying around. In some specific embodiments, the recycling pipe is connected to a box for holding the recycled release film.

[0048] Preferably, the first direction is Figure 1 In the X direction, the third direction is Figure 1 The Z direction in the equation.

[0049] Continue reading Figure 1 Furthermore, in some specific embodiments, a third substrate 1231 is fixedly disposed on the mounting plate 110, and a guide wheel 123 is disposed on the third substrate 1231. Specifically, a connecting shaft connects the third substrate 1231 and the guide wheel 123. The guide wheel 123 rotates at one end of the connecting shaft. The width direction of the release film is parallel to the axial direction of the guide wheel 123. The release film contacts the wheel surface of the guide wheel 123 to complete the guiding and flattening action.

[0050] See Figure 1 and Figure 2In some specific embodiments, the motion clamping assembly 121 further includes a first base plate 1214 and a first connecting plate 1213. The first base plate 1214 is fixedly connected to the output end of the drive mechanism 130, and the first connecting plate 1213 is fixedly connected to the first base plate 1214. A first clamping member 1211 is disposed on the first connecting plate 1213, and the first clamping member 1211 is connected to a first driving member 1212 to drive the first clamping member 1211 to open and clamp. The movement of the first base plate 1214 and the first connecting plate 1213 drives the first clamping member 1211 to move, and the drive mechanism 130 drives the first clamping member 1211 to reciprocate along the Z direction.

[0051] In some specific embodiments, the first driving member 1212 is configured as a cylinder, and the first driving member 1212 is configured as a gripper. The cylinder drives the gripper to move towards or away from each other along a first direction to perform opening or clamping actions.

[0052] See Figure 3 and Figure 4 , Figure 3 This paper shows a schematic diagram of the release film recycling device 10 according to some embodiments of this application from another perspective. Figure 4 It shows Figure 3 A magnified view of a portion of point N.

[0053] In some specific embodiments, the first substrate 1214 has a first strip-shaped hole 12141 extending along a second direction. The first connecting plate 1213 is connected to the first substrate 1214 through the first strip-shaped hole 12141 and its position relative to the first substrate 1214 in the second direction is adjusted. The first connecting plate 1213 can be adjusted in position along the length direction of the first strip-shaped hole 12141, thereby adjusting the position of the first clamping member 1211.

[0054] Preferably, the second direction is Figure 3 in the Y direction.

[0055] See Figure 1 and Figure 2 In some specific embodiments, the fixed clamping assembly 122 further includes a second connecting plate 1223, which is fixedly connected to the mounting plate 110. A second clamping member 1221 is disposed on the second connecting plate 1223, and a second driving member 1222 is connected to the second clamping member 1221 to drive it to open and clamp. The second connecting plate 1223 enables the second clamping member 1221 to be better fixed.

[0056] In some specific embodiments, the second driving member 1222 is configured as a cylinder, and the second driving member 1222 is configured as a gripper. The cylinder drives the gripper to move towards or away from each other along the first direction to perform opening or clamping actions.

[0057] Specifically, when the clamping portions of the first clamping member 1211 and the second clamping member 1221 are in the clamping state, the clamping portions of the two are located on the same straight line and are aligned in the Z direction, so that the release film clamped by the two is straightened in the Z direction.

[0058] See Figure 1 , Figure 3 , Figure 4 and Figure 5 , Figure 5 A partial structural schematic diagram of a release film recycling device according to some embodiments of this application is shown.

[0059] In some specific embodiments, the fixed clamping and feeding assembly 122 further includes a second base plate 1224, a first adjusting block 1225, and a second adjusting block 1226. The second base plate 1224 is connected between the second connecting plate 1223 and the mounting plate 110. The side of the second base plate 1224 facing the mounting plate 110 has a second strip-shaped hole 12241 extending in a second direction. The position of the second base plate 1224 can be adjusted along the length direction of the first strip-shaped hole 12241, thereby adjusting the position of the second connecting plate 1223 and the second clamping and feeding member 1221 connected to the second base plate 1224.

[0060] Specifically, the second substrate 1224 has an L-shaped structure, with the two plates on both sides of the corner connected to the mounting plate 110 and the second connecting plate 1223, respectively.

[0061] In some specific embodiments, a first adjusting block 1225 is disposed on the coplanar end face of the second substrate 1224 and the second connecting plate 1223. The first adjusting block 1225 adjusts the position of the second connecting plate 1223 relative to the second substrate 1224 in a first direction. Specifically, the first adjusting block 1225 is fixedly mounted on the side of the second substrate 1224 through two screw holes, the axis of which extends along the X direction. Two more screw holes and one set screw hole are also provided on the surface where the screw holes of the first adjusting block 1225 are located, and it is connected to the second connecting plate 1223. By adjusting the screws and set screw, the second connecting plate 1223 is pushed and pulled along the X direction, i.e., reciprocated, thereby adjusting the position of the second clamping member 1221 in the X direction.

[0062] In some specific embodiments, the second adjusting block 1226 is connected between the mounting plate 110 and the second substrate 1224, and adjusts the position of the second substrate 1224 and the second connecting plate 1223 relative to the mounting plate 110 in the second direction through the second slot 12241 and the second adjusting block 1226. Further, the mounting plate 110 is also provided with a side plate 111, which is parallel to the mounting plate 110 and is used to compensate for the inconvenience of mounting certain components on the mounting plate 110 in terms of shape. Specifically, the shape of the side plate 111 is designed to avoid the transport clamping assembly moving along the Z direction.

[0063] Specifically, the second adjusting block 1226 is fixedly connected to one side of the side plate 111. The second adjusting block 1226 is connected to the second base plate 1224 through screw holes. The second connecting plate 1223 has a groove to avoid the second adjusting block 1226. By adjusting the screws connecting the second adjusting block 1226 and the second base plate 1224, the position of the second base plate 1224 and the second connecting plate 1223 can be adjusted along the Y direction, thereby adjusting the position of the second clamping member 1221 in the Y direction, moving it closer to or further away from the first clamping member 1211.

[0064] See Figure 1 , Figure 3 and Figure 6 , Figure 6 A schematic diagram of the handover position of the release film recycling device according to some embodiments of this application is shown.

[0065] In some specific embodiments, the first clamping member 1211 has an initial position and a handover position, such as Figure 1 As shown, when the first clamping component 1211 is in its initial position, it is located on one side of the second clamping component 1221 in a third-order orientation; as Figure 6 As shown, when the first clamping member 1211 is in the handover position, the first clamping member 1211 is located on the other side of the second clamping member 1221 in the third direction, and the drive mechanism 130 drives the first clamping member 1211 to switch between the initial position and the handover position.

[0066] The first clamping component 1211 is in motion, such as... Figure 1 As shown, the release film is moved from the initial position to the junction position. Figure 6 As shown, the second clamping member 1221 clamps the release film, the first clamping member 1211 releases and returns to the initial position, clamps the release film again, the second clamping member 1221 releases the release film, and the first clamping member 1211 moves from the initial position to the junction position while holding the release film, thereby continuously pulling the release film down along the Z direction.

[0067] See Figure 7 , Figure 8 and Figure 9 , Figure 7A front view of a gripper according to some embodiments of this application is shown. Figure 8 It shows Figure 7 AA section view, Figure 9 It shows Figure 7 BB section view in the middle.

[0068] In some specific embodiments, the first clamping member 1211 and the second clamping member 1221 are configured as a type of gripper, which includes two opposing clamping surfaces 199, the two clamping surfaces 199 being rough planes, such as... Figure 9 One of the clamping surfaces 199 shown is a complete plane, in contact with the adhesive side of the release film; as shown Figure 8 The other clamping surface 199 shown has a groove that contacts the adhesive side of the release film. The length direction of the groove is perpendicular to a third direction. Both clamping surfaces 199 are roughened by electrical discharge machining to increase the friction between the clamps and the release film, preventing slippage and adhesive sticking. The groove is used to accommodate residual adhesive on the release film; the residual adhesive in the groove can be cleaned periodically according to actual production conditions.

[0069] See Figure 10 , Figure 11 and Figure 12 , Figure 10 The following is a front view of a type II gripper according to some embodiments of this application. Figure 11 It shows Figure 10 CC section view in Figure 12 It shows Figure 10 DD section view in the image.

[0070] In some specific embodiments, the first clamping member 1211 and the second clamping member 1221 are configured as type II grippers. Each type II gripper includes two opposing clamping surfaces 199, which are flat surfaces with the same rough shape. Figure 11 As shown, one of the clamping surfaces 199 contacts the adhesive side of the release film, and a rough surface is formed by electrical discharge machining to increase friction and prevent slippage; as Figure 12 As shown, another clamping surface 199 contacts the adhesive side of the release film, and its surface is provided with a contact surface coated with Teflon to prevent adhesive adhesion.

[0071] Specifically, the contact surface is set on the contact block, which is made of Teflon material and has a non-adhesive function. The contact block has countersunk mounting holes, through which the contact block is connected to the clamps. The screw head can be embedded in the countersunk mounting holes and will not protrude from the contact surface.

[0072] See Figure 13 , Figure 14 and Figure 15 , Figure 13 The following is a front view of three types of grippers according to some embodiments of this application. Figure 14 It shows Figure 13 EE section view, Figure 15 It shows Figure 13 FF section view in the image.

[0073] In some specific embodiments, the first clamping member 1211 and the second clamping member 1221 are configured as three-type grippers. Each three-type gripper includes two opposing clamping surfaces 199, which are flat planes of the same shape located at one end of the gripper. The length direction of the clamping surfaces 199 is perpendicular to the third direction, and the clamping surfaces 199 are coated with a high surface tension coating. Specifically, the high surface tension coating can be a nano-coating, a Teflon coating, etc., which increases the friction between the clamping surfaces 199 and the release film while preventing adhesion, thus giving the grippers anti-adhesion and anti-slip functions.

[0074] See Figure 1 and Figure 2 In some specific embodiments, the drive mechanism 130 includes a lead screw module 133, a coupling 132, and a motor 131. The lead screw module 133 is fixed on the mounting plate 110. The motor 131 provides power and transmits it to the lead screw module 133 through the coupling 132. The lead screw in the lead screw module 133 drives the sliding seat to move up and down in the Z direction. The first base plate 1214 is fixedly connected to the sliding seat. As the sliding seat reciprocates in the Z direction, the first clamping member 1211 moves in the Z direction.

[0075] In some specific embodiments, the lead screw module 133 can be replaced by other actuators, such as cylinders, belts, gear racks, chains, etc., to realize the reciprocating linear motion of the motion clamping assembly 121.

[0076] In some specific embodiments, during the Z-direction movement of the screw module 133 driving the motion clamping assembly 121, a photoelectric switch is provided on the mounting plate 110, which serves as the starting point for the drive mechanism 130 to drive the motion clamping assembly 121 and as a reference for the upper and lower limit positions of the motion clamping assembly 121.

[0077] In use, the release film recycling device 10 provided by the present invention uses a motor 131 to drive a lead screw module 133 to move, and a moving clamping assembly 121 to reciprocate in the Z direction. The position of the first connecting plate 1213 can be adjusted in the Y direction for the first clamping member 1211. The fixed clamping assembly 122 is fixed on the mounting plate 110, and the first adjusting block 1225 and the second adjusting block 1226 can be used to adjust the movement of the second clamping member 1221 in the X and Y directions. The first clamping member 1211 and the second clamping member 1221 are each configured as grippers mounted on a cylinder. The cylinder drives the two grippers to move closer together or further apart, clamping or releasing the release film. The gripper portions of the first clamping member 1211 and the second clamping member 1221 are located in the same position in the Z direction. The first clamping member 1211 clamps the release film and moves downward along the Z direction from the initial position, passing through the middle of the open second clamping member 1221 to reach the junction position. The second clamping member 1221 clamps the release film again. After the first clamping member 1211 releases the release film, it moves upward along the Z direction, so that the second clamping member 1221 passes through the middle of the first clamping member 1211 to reach the initial position. The first clamping member 1211 clamps the release film again, and the second clamping member 1221 releases the release film. The first clamping member 1211 moves downward along the Z direction, repeating the above pulling action to achieve continuous transfer of the release film. The guide wheel 123 contacts the release film portion transferred downward along the Z direction, so that the release film is guided and stretched, and sucked away by the recycling pipe below the guide wheel 123.

[0078] The release film recycling device 10, which employs a linear motion mechanism, effectively ensures the accuracy of the release film's length. The design of the clamping and conveying action keeps the release film in a stable tension state at all times. The clamping and releasing of the material strip by the grippers are performed when the release film is straightened, rather than when it is relaxed, resulting in higher material recycling accuracy. The release film maintains a stable tension and accurate length, reducing the problem of ACF material strip and ACF adhesive being stretched and deformed, and improving bonding accuracy.

[0079] The gripper structure design of the first clamping component 1211 and the second clamping component 1221, along with surface treatment processes such as electrical discharge machining and nano-coating, effectively reduces the problems of sticking and slipping of the grippers during the recovery of the release film, and also prevents sticking from affecting the length of the release film.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
