Description

Technical Field

[0001] This invention relates to the field of flexible material processing equipment, and in particular to a transparent release film winding device. Background Technology

[0002] In recent years, with the increasing popularity of wireless charging in smartphones, wireless charging technology has developed at an astonishing pace. Flexible material bonding and assembly has also become the mainstream production method in the industry, with assembly and bonding mechanisms widely used. However, the application of some flexible materials has also created certain limitations and hindered mass production in assembly and bonding. For example, graphite is inherently soft and prone to defects such as bubbles and dents during bonding. Therefore, a release film needs to be added to the substrate before assembly and bonding. The final step in assembly and bonding requires applying a release film to the finished product to protect the substrate surface and prevent foreign objects from adhering to the substrate surface. At the bonding and assembly station, the release film needs to be separated from the substrate before other components are bonded to the substrate surface. However, since existing release films are generally made of transparent materials, and the sensors in current technology cannot detect the position of the transparent release film, the transparent release film flows with the substrate to subsequent stations, preventing subsequent stations from bonding other components to the substrate, causing finished product scrap and resulting in low production yield. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a transparent release film winding device with high production yield.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a transparent release film winding device, comprising a winding motor, a winding shaft, and a conveyor table. The winding motor is used to drive the winding shaft to rotate, the conveyor table is used to transport the substrate, and the winding shaft is used to wind the transparent release film. The device also includes a detection frame and a sensing rocker arm and a sensor respectively mounted on the detection frame. The sensor is electrically connected to the winding motor. One end of the sensing rocker arm is rotatably connected to the detection frame, and the other end is provided with a sensing plate for triggering the sensor. After the transparent release film separates from the substrate, it is wound onto the winding shaft via the sensing plate. The detection frame is also provided with a limiting member, which is used to abut against the side of the sensing rocker arm opposite to the winding shaft.

[0005] The beneficial effects of this invention are as follows: The transparent release film winding device provided by this invention has the characteristics of high production yield. It is equipped with a sensor electrically connected to the roll motor, and a sensing plate for triggering the sensor is set at the swing end of the sensing rocker arm, so that the roll motor can control the rotation of the roll shaft in real time following the movement of the substrate, thereby winding up the transparent release film; ensuring that the transparent release film can be completely separated from the substrate, thus improving the production yield; the limiting component can limit the sensing rocker arm, avoiding collision with the sensor due to excessive inertia when the sensing rocker arm swings back.

[0014] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0015] Please refer to Figures 1 to 6 A transparent release film winding device includes a winding motor, a winding shaft 8, and a conveyor table 5. The winding motor drives the winding shaft 8 to rotate, the conveyor table 5 conveys a substrate 6, and the winding shaft 8 winds up the transparent release film 63. The device also includes a detection frame 1 and a sensing rocker arm 2 and a sensor 7 respectively mounted on the detection frame 1. The sensor 7 is electrically connected to the winding motor. One end of the sensing rocker arm 2 is rotatably connected to the detection frame 1, and the other end is provided with a sensing plate 3 for triggering the sensor 7. After the transparent release film 63 separates from the substrate 6, it is wound onto the winding shaft 8 through the sensing plate 3.

[0016] The working principle of this invention is briefly described as follows: When the substrate 6 moves, the transparent release film 63 near one end of the substrate 6 is in an unwound state. At this time, the transparent release film 63 does not exert any pushing force on the sensing plate 3, the sensing rocker arm 2 does not swing, the sensing plate 3 is in a vertical state under the action of gravity and triggers the sensor 7. The sensor 7 controls the start of the winding motor, thereby causing the winding shaft 8 to wind the transparent release film 63. The transparent release film 63 in the winding state will exert a pushing force on the sensing plate 3, causing the sensing plate 3 to move away from the sensor 7. When the sensing plate 3 swings outside the sensing range of the sensor 7, the roll motor stops rotating. As the substrate 6 moves, the transparent release film 63 near the substrate 6 continues to unwind, causing the sensing plate 3 to swing back into the sensing range of the sensor 7. At this time, the roll shaft 8 continues to repeat the above winding action. When the sensing plate 3 swings to the critical point of the sensing range of the sensor 7, the winding action of the roll shaft 8 and the unwinding action of the transparent release film 63 when the substrate 6 is feeding reach a dynamic balance, and the transparent release film 63 can be wound up in real time.

[0017] As can be seen from the above description, the beneficial effects of the present invention are as follows: the sensor 7 is electrically connected to the roll motor, and a sensing plate 3 for triggering the sensor 7 is provided at the swing end of the sensing rocker arm 2, so that the roll motor can control the rotation of the roll shaft 8 in real time to follow the movement of the substrate 6, thereby winding up the transparent release film 63; ensuring that the transparent release film 63 can be completely separated from the substrate 6, thus improving the production yield.

[0018] Furthermore, the detection frame 1 is also equipped with an extension bracket 4, and the sensor 7 is mounted on the extension bracket 4.

[0019] Furthermore, the extension bracket 4 includes a first extension 41 and a second extension 42 connected together. The first extension 41 extends along the X-axis direction, and the second extension 42 extends along the Y-axis direction. The first extension 41 is connected to the detection frame 1, and the sensor is installed on the second extension 42.

[0020] As can be seen from the above description, the extension bracket 4 facilitates the installation of the sensor 7 and ensures the stability of the sensor 7's operation.

[0021] Furthermore, the detection frame 1 is provided with a height adjustment groove 13 extending along the Z-axis direction. The first extension 41 is slidably installed in the height adjustment groove 13. The height adjustment groove 13 is provided with a first locking member 14 connected to the first extension 41. The first locking member 14 is used to lock the first extension 41 in the height adjustment groove 13.

[0022] As described above, the height adjustment groove 13 facilitates the adjustment of the height of the extension bracket 4, thereby adjusting the position height of the sensor 7, which is convenient for production debugging and helps to improve the production yield.

[0023] Furthermore, the first extension 41 is provided with a gap adjustment groove extending along the X-axis direction, and the second extension 42 is slidably installed in the gap adjustment groove. The gap adjustment groove is provided with a second locking member connected to the second extension 42, and the second locking member is used to lock the second extension 42 in the gap adjustment groove.

[0024] As described above, the gap adjustment groove facilitates the adjustment of the gap between the second extension 42 of the extension bracket 4 and the sensing plate 3, thereby adjusting the minimum gap between the sensor 7 and the sensing plate 3, which is convenient for production debugging and helps to improve the production yield.

[0025] Furthermore, the second extension 42 is provided with a width adjustment groove 421, and the sensor 7 is slidably mounted in the width adjustment groove 421. A third locking member 422 connected to the sensor 7 is provided in the width adjustment groove 421, and the third locking member 422 is used to lock the sensor 7 in the width adjustment groove 421.

[0026] As can be seen from the above description, the width adjustment groove 421 facilitates the adjustment of the position of the sensor 7 on the second extension 42, which is convenient for production debugging and helps to improve the production yield.

[0027] Furthermore, the detection frame 1 is also provided with a limiting member 11, which is used to abut against the side of the sensing rocker arm 2 away from the roll shaft 8.

[0028] As can be seen from the above description, the limiting member 11 can limit the sensing rocker arm 2 to avoid the sensing rocker arm 2 from colliding with the sensor 7 due to excessive inertia when it swings back.

[0029] Furthermore, the limiting member 11 includes a limiting seat 111 connected to the detection frame 1, and the limiting seat 111 has a receiving groove 114 on the side near the sensing rocker arm 2.

[0030] As can be seen from the above description, the receiving slot 114 facilitates the receiving of the sensing rocker arm 2, ensuring the accuracy of the swing position of the sensing rocker arm 2.

[0031] Furthermore, the limiting member 11 also includes an elastic member 112 and an abutment member 113 installed in the receiving groove 114. One end of the elastic member 112 is connected to the limiting seat 111, and the other end is connected to the abutment member 113. The abutment member 113 is used to abut against the sensing rocker arm 2.

[0032] As can be seen from the above description, the elastic element 112 and the abutting element 113 can effectively buffer the swing of the sensing ratio.

[0033] Furthermore, the contact member 113 is provided with a buffer layer 115 on the side near the sensing rocker arm 2.

[0034] Example 1

[0035] Please refer to Figures 1 to 6 Embodiment 1 of the present invention is: a transparent release film winding device, including a winding motor (not shown), a winding shaft 8, and a conveyor table 5. The winding motor is used to drive the winding shaft 8 to rotate, and the conveyor table 5 is used to transport a substrate 6. The substrate 6 includes a carrier film 61 and a material 62 attached to the carrier film 61. A transparent release film 63 is also attached to the carrier film 61 and the material 62. The winding shaft 8 is used to wind up the transparent release film 63. The device also includes a detection frame 1 and a sensing rocker arm 2 and a sensor 7 respectively installed on the detection frame 1. The device 7 is electrically connected to the winding motor; one end of the sensing rocker arm 2 is rotatably connected to the detection frame 1, the detection frame 1 is provided with a rotating shaft 12, the sensing rocker arm 2 is mounted on the rotating shaft 12, and the other end of the sensing rocker arm 2 is provided with a sensing plate 3 for triggering the sensor 7. After the transparent release film 63 is separated from the substrate 6, it is wound onto the winding shaft 8 through the sensing plate 3; specifically, when the substrate 6 moves, the transparent release film 63 near the substrate 6 is in an unwinding state. At this time, the transparent release film 63 does not apply a pushing force to the sensing plate 3, and the sensing rocker arm 2 does not swing (e.g. Figure 4 As shown, the sensing plate 3 is in a vertical state under the action of gravity and triggers the sensor 7. The sensor 7 controls the start of the roll motor, which causes the roll shaft 8 to wind up the transparent release film 63. The transparent release film 63 in the winding state will exert a pushing force on the sensing plate 3, causing the sensing plate 3 to swing away from the sensor 7. When the sensing plate 3 swings out of the sensing range of the sensor 7, the roll motor stops rotating. As the substrate 6 moves, the transparent release film 63 near the substrate 6 continues to unwind, causing the sensing plate 3 to swing back into the sensing range of the sensor 7. At this time, the roll shaft 8 continues to repeat the above winding action. When the sensing plate 3 swings to the critical point of the sensing range of the sensor 7, the winding action of the roll shaft 8 and the unwinding action of the transparent release film 63 when the substrate 6 is feeding are dynamically balanced, and the transparent release film 63 can be wound up in real time.

[0036] For the best option, please refer to the following: Figure 3 The detection frame 1 is also equipped with an extension bracket 4, and the sensor 7 is installed on the extension bracket 4. Specifically, the extension bracket 4 includes a first extension 41 and a second extension 42 connected to each other. The extension bracket 4 is an integrally formed structure. The first extension 41 extends along the X-axis direction, and the second extension 42 extends along the Y-axis direction. The first extension 41 is connected to the detection frame 1, and the sensor is installed on the second extension 42. The extension bracket 4 facilitates the installation of the sensor 7 and ensures the stability of the sensor 7's operation.

[0037] Please combine Figure 5 In this embodiment, the detection frame 1 is provided with a height adjustment groove 13 extending along the Z-axis direction. The first extension 41 is slidably installed in the height adjustment groove 13. The height adjustment groove 13 is provided with a first locking member 14 connected to the first extension 41. The first locking member 14 is used to lock the first extension 41 in the height adjustment groove 13. The height adjustment groove 13 facilitates the adjustment of the height of the extension bracket 4, thereby adjusting the position height of the sensor 7, which is convenient for production debugging and helps to improve the production yield.

[0038] In other embodiments, the first extension 41 and the second extension 42 are detachably connected. The first extension 41 is provided with a gap adjustment groove extending along the X-axis direction. The second extension 42 is slidably installed in the gap adjustment groove. The gap adjustment groove is provided with a second locking member connected to the second extension 42. The second locking member is used to lock the second extension 42 in the gap adjustment groove. In this way, the gap between the second extension 42 of the extension bracket 4 and the sensing plate 3 can be adjusted by adjusting the sliding stroke of the second extension 42 in the gap adjustment groove, thereby adjusting the minimum gap between the sensor 7 and the sensing plate 3, which is convenient for production debugging and helps to improve the production yield.

[0039] Please combine Figure 1 In this embodiment, the second extension 42 is provided with a width adjustment groove 421, and the sensor 7 is slidably mounted in the width adjustment groove 421. The width adjustment groove 421 is provided with a third locking member 422 connected to the sensor 7. The third locking member 422 is used to lock the sensor 7 in the width adjustment groove 421. The width adjustment groove 421 facilitates the adjustment of the position of the sensor 7 on the second extension 42, which is convenient for production debugging and helps to improve the production yield.

[0040] For the best option, please refer to the following: Figure 6The detection frame 1 is also provided with a limiting member 11, which is used to abut against the side of the sensing rocker arm 2 away from the roll shaft 8. The limiting member 11 can limit the sensing rocker arm 2 to avoid it colliding with the sensor 7 due to excessive inertia when swinging back. Specifically, the limiting member 11 includes a limiting seat 111 connected to the detection frame 1. The limiting seat 111 has a receiving groove 114 on the side near the sensing rocker arm 2. The receiving groove 114 facilitates the reception of the sensing rocker arm 2, ensuring the accuracy of the swing position of the sensing rocker arm 2. The limiting member 11 also includes an elastic member 112 and an abutment member 113 installed in the receiving groove 114. One end of the elastic member 112 is connected to the limiting seat 111, and the other end is connected to the abutment member 113. The abutment member 113 is used to abut against the sensing rocker arm 2. The elastic member 112 and the abutment member 113 can effectively buffer the swing of the sensing rocker arm. In this embodiment, the elastic member 112 is a spring, and the abutment member 113 has a buffer layer 115 on the side near the sensing rocker arm 2. The buffer layer 115 is made of rubber.

It incorporates a sensor electrically connected to a roll motor, and a sensor plate at the swing end of the induction rocker arm to trigger the sensor. This allows the roll motor to control the roll shaft rotation in real time, following the movement of the substrate, thereby winding the transparent release film. This ensures the transparent release film can be completely separated from the substrate, improving production yield.
