Description

Technical Field

[0001] This invention relates to the field of curing apparatus for AD adhesives and PI films, and more specifically to a curing apparatus for AD adhesives and PI films. Background Technology

[0002] With the trend towards thinner and lighter mobile phones, in order to achieve the convenience of high-current fast charging, the rigid-flex PCB of the battery protection board, while still using a thick copper design, also needs to reduce the overall thickness of the rigid-flex PCB. After improvement, the current production process involves attaching AD adhesive and PI film to the flexible PCB area, connecting the copper in the scrap area to the copper in the retrieval tank, and staggering the PI film and CVL film to reduce step differences and make the AD adhesive bond more firmly to the flexible PCB area. Finally, baking is performed to cure the AD adhesive. This solution not only eliminates adhesive overflow defects but also reduces production costs by approximately 10% compared to traditional processes.

[0003] Most existing curing devices first fix the bonding plate, and then heat it by irradiating the AD adhesive on its surface with an infrared lamp from a certain distance. However, this method is not conducive to preventing the flowing air from carrying away the surface temperature of the AD adhesive, which can easily lead to unstable curing temperature. If the curing temperature is too high, it can easily cause the adhesive to leak or make the adhesive layer brittle, resulting in a decrease in bonding strength. If the curing temperature is too low, the molecular chain movement of the matrix will be difficult, which will result in an insufficient crosslinking density of the adhesive layer and the curing reaction will not be completed.

[0004] Furthermore, due to the different sizes of the bonding plates, the optimal distance for infrared lamps to irradiate the AD adhesive also varies, which makes it difficult to control the stability of the curing temperature, resulting in poor curing effect. Summary of the Invention

[0005] The purpose of this invention is to provide a curing device for AD adhesive and PI film, which can avoid the influence of airflow on the curing temperature and adjust the distance between the infrared lamp and AD adhesive according to the different sizes of the bonding plate.

[0010] Preferably, the top of the base has a pair of slots, and the inner walls on both sides of the slots are inclined structures. The top of the first rack and the top of the connecting plate pass through the two slots and are slidably connected to them.

[0011] Preferably, the fixing assembly includes a pair of clamping plates, a first bidirectional threaded rod, and a pair of first springs. The bottom of the clamping plates passes through the top wall of the heating table and is slidably connected to it. The bidirectional threaded rod is rotatably installed between the inner walls of both ends of the heating table. The clamping plates are threadedly connected to the outer periphery of the first bidirectional threaded rod. The threaded holes on the two clamping plates are in opposite directions. The pair of first springs are symmetrically distributed on both sides of the first bidirectional threaded rod. The two ends of the first springs are respectively fixedly connected to the opposite ends of the two clamping plates.

[0012] Preferably, the fixing assembly further includes a rotating rod, an elastic metal plate, a sleeve, a pressure block, and a second spring.

[0013] Preferably, a pair of sliding grooves are provided on one side of the heating chamber, and the sliding grooves are slidably connected to the protrusions at both ends of the lifting door. A pair of spring dampers are fixedly connected to the top of the heating chamber, and the two spring dampers are symmetrically distributed at both ends of the lifting door. The top of the telescopic end of the spring damper is fixedly connected to the lifting door.

[0014] Preferably, the pitch adjustment assembly includes a second bidirectional threaded rod, a pair of U-shaped sliders, and a motor. The second bidirectional threaded rod is rotatably mounted between the inner walls of both ends of the heating chamber. The top of the U-shaped slider is in contact with the top wall of the heating chamber, and the bottom of the U-shaped slider is rotatably mounted on the U-shaped slider with an infrared irradiation lamp.

[0017] The beneficial effects of this invention are:

[0018] 1. The present invention fixes the bonding plate to the top of the heating table by fixing components, and then pushes the heating table into the heating chamber by moving components. The heating chamber and the lifting door ensure that the curing process is carried out in a closed space, avoiding airflow from affecting the stability of the heating temperature, thereby preventing temperature fluctuations from causing a decrease in curing quality.

[0019] 2. In the process of the heating table entering the heating chamber from the outside, the present invention drives the lifting door to open and close through the linkage component, thereby facilitating the delivery of the bonding plate into the heating chamber. Furthermore, the linkage component transmission method avoids the lifting door from being open for a long time, which would cause internal heat loss and save energy.

[0020] 3.

When it moves to the point where it abuts against the top of one of the clamping plates, the infrared irradiation lamp is in the optimal irradiation position. This allows the position of the infrared irradiation lamp to change according to the size of the connecting plate, further ensuring the stability of the heating temperature.

[0041] like Figures 1 to 9 As shown:

[0042] The enclosure 1 includes a housing 1 and a pair of infrared irradiation lamps 14, which are installed inside the housing 1 and used to heat and bake the AD adhesive and PI film to cure them. The enclosure further includes a heating platform 15, a moving assembly 2, a fixing assembly 3, a linkage assembly 4, and an adjusting assembly 5. The heating platform 15 is mounted on the housing 1 via the moving assembly 2 and is used to fix the bonding plate. The moving assembly 2 is used to move the heating platform 15 into the heating chamber 11. The housing 1 includes a base 10, a heating chamber 11, and a lifting door 13. The bottom of the heating chamber 11 is fixedly connected to the top of the base 10. The lifting door 13 is vertically slidably installed at one end of the heating chamber 11. The fixing component 3 is installed on the heating platform 15. The fixing component 3 is used to fix the bonding plate. The bonding plate is fixed to the top of the heating platform 15 by the fixing component 3. Then, the heating platform 15 is pushed into the heating chamber 11 by the moving component 2. The heating chamber 11 and the lifting door 13 ensure that the curing process is carried out in a closed space to avoid airflow affecting the stability of the heating temperature, thereby preventing temperature fluctuations from causing a decrease in curing quality. A first rack 16 is fixedly connected to the bottom of the heating platform 15. The first rack 16 is horizontally slidable on the base 10 and meshes with the input end of the linkage component 4. The linkage component 4 is installed on the base 10, and its output end is fixedly connected to the lifting door 13. During the process of the heating platform 15 entering the heating chamber 11 from the outside, the lifting door 13 is driven to open and close through the linkage component 4, thus facilitating the delivery of the bonding plate into the heating chamber 11. Furthermore, the linkage component 4 prevents the lifting door 13 from remaining open for extended periods, thus avoiding heat loss and saving energy. An adjusting component 5 is installed inside the heating chamber 11 and is used to adjust the distance between the two infrared irradiation lamps 14. After the heating platform 15 enters the heating chamber 11, the adjusting component 5 moves the two infrared irradiation lamps 14 to appropriate positions according to the size of different bonding plates, thereby further ensuring the stability of the heating temperature.

[0043] like Figures 1 to 7 As shown:

[0044] Linkage component 4 includes a fixed plate 40, a rotating shaft 41, a first gear 42, a pair of second gears 43, and a second rack 44. The top of the fixed plate 40 is fixedly connected to the top wall of the base 10. One end of the fixed plate 40 is rotatably connected to the rotating shaft 41 and one of the second gears 43. The other second gear 43 and the first gear 42 are coaxially connected to the periphery of the rotating shaft 41. The two second gears 43 mesh with each other. The top second gear 43 and the first gear 42 are both input ends of the transmission component. The second rack 44 meshes with the first gear 42. The second rack 44 is the linking component 4. Output end; When the heating platform 15 is located at the end furthest from the heating chamber 11, the first rack 16 meshes with the first gear 42; when the heating platform 15 drives the connecting plate to move, upon entering the heating chamber 11, the meshing transmission between the first rack 16 and the first gear 42, and the meshing transmission between the first gear 42 and the second rack 44, can drive the lifting door 13 to rise. After the heating platform 15 passes the bottom of the lifting door 13, the first rack 16 disengages from the first gear 42, and the lifting door 13 falls again under the action of gravity, thereby conveying the connecting plate into the heating chamber 11. When the heating platform 15 is located at the end closest to the heating chamber 11, the first rack 16 meshes with the second gear 43 at the top. Upon exiting the heating chamber 11, the meshing transmission between the first rack 16 and the top second gear 43, and the meshing transmission between the two second gears 43, drives the rotating shaft 41 and the first gear 42 to rotate. Through the meshing transmission between the first gear 42 and the second rack 44, the lifting door 13 rises again. Then, after the heating platform 15 passes the bottom of the lifting door 13, it falls again, facilitating the removal of the connecting plate. Furthermore, because the diameter of the second gear 43 is smaller than that of the first gear 42, the lifting door 13 rises faster upon exiting, thus adapting to the limited space of the heating chamber 11 and reducing the stroke of the heating platform 15.

[0045] like Figures 1 to 7 As shown:

[0046] The moving component 2 includes a hydraulic rod 20, which is fixedly connected to the inner wall of one side of the base 10. A connecting plate 17 is fixedly connected to the bottom of the heating platform 15. The connecting plate 17 is horizontally slidably mounted on the base 10. The telescopic end of the hydraulic rod 20 passes through the connecting plate 17 and is slidably connected to it. When the hydraulic rod 20 is activated, the heating platform 15 can be moved on top of the base 10 via the connecting plate 17. The connecting plate 17 is slidably connected to the telescopic end of the hydraulic rod 20, thereby cooperating with the linkage component 4 to adjust the position of the first rack 16.

[0047] like Figures 1 to 4 As shown:

[0048] The base 10 has a pair of slots 100 on its top. The inner walls of both sides of the slots 100 are inclined. The top of the first rack 16 and the top of the connecting plate 17 pass through the two slots 100 and are slidably connected to them. When the heating platform 15 moves, it drives the first rack 16 and the connecting plate 17 to slide along the two slots 100 respectively. When they slide to one end of the slot 100, as the heating platform 15 continues to move, the first rack 16 and the connecting plate 17 slide along the inclined surfaces of the two slots 100 respectively. At this time, the first rack 16 is disengaged from both input ends of the linkage component 4. After the lifting door 13 descends, the first rack 16 finally disengages from one input end of the linkage component 4 and engages with its other input end.

[0049] like Figures 1 to 8 As shown:

[0050] The fixing component 3 includes a pair of clamping plates 30, a first bidirectional threaded rod 31, and a pair of first springs 32. The bottom of the clamping plate 30 passes through the top wall of the heating table 15 and is slidably connected to it. The bidirectional threaded rod is rotatably installed between the inner walls of both ends of the heating table 15. The clamping plate 30 is threadedly connected to the outer periphery of the first bidirectional threaded rod 31. The threaded holes on the two clamping plates 30 are in opposite directions. The pair of first springs 32 are symmetrically distributed on both sides of the first bidirectional threaded rod 31. The two ends of the first springs 32 are respectively fixedly connected to the opposite ends of the two clamping plates 30. A pair of symmetrically distributed first springs 32, which are always in a stretched state, provide tension to the two clamping plates 30, causing the two clamping plates 30 to move closer to each other. When fixing the connecting plate, one of the clamping plates 30 is pulled apart. Through the threaded transmission between the clamping plate and the first bidirectional threaded rod 31, the two clamping plates 30 are moved away from each other synchronously. The first springs 32 are further stretched, and the connecting plate is placed between the two clamping plates 30 on the top of the heating table 15. Then the clamping plates 30 are released, the first springs 32 contract, and the first bidirectional threaded rod 31 rotates in the opposite direction, causing the two clamping plates 30 to move closer to each other and clamp the connecting plate.

[0051] like Figures 1 to 8 As shown:

[0052] The fixing assembly 3 also includes a rotating rod 33, an elastic metal plate 34, a sleeve 35, a pressure block 36, and a second spring 37. The bottom of the rotating rod 33 is rotatably connected to the top of the heating table 15, the top of the rotating rod 33 is fixedly connected to one end of the bottom of the elastic metal plate 34, the other end of the bottom of the elastic metal plate 34 is fixedly connected to the top of the sleeve 35, the top of the pressure block 36 is slidably connected to the inner wall of the sleeve 35, the second spring 37 is located inside the sleeve 35, one end of the second spring 37 is fixedly connected to the top wall of the sleeve 35, and the other end of the second spring 37 is fixedly connected to the top of the pressure block 36. Rotate the elastic metal plate 34 to drive the rotating rod 33 to rotate on the top of the heating table 15, and lift the sleeve 35 to the top, causing the elastic metal plate 34 to deform. When the sleeve 35 moves to the top of the bonding plate, release the elastic metal plate 34, and the elastic metal plate 34 rebounds, pushing the sleeve 35 downward. At this time, the bottom of the pressure block 36 abuts against the top of the bonding plate to further fix the bonding plate and prevent shaking during movement, which could result in poor curing quality or even movement of the PI film and CVL film. The second spring 37 contracts inside the sleeve 35 to prevent excessive downward pressure from damaging the bonding plate.

[0053] like Figures 1 to 4 As shown:

[0054] A pair of sliding grooves 110 are provided on one side of the heating chamber 11. The sliding grooves 110 are slidably connected to the protrusions at both ends of the lifting door 13. A pair of spring dampers 12 are fixedly connected to the top of the heating chamber 11. The two spring dampers 12 are symmetrically distributed at both ends of the lifting door 13, and the top of the telescopic end of the spring damper 12 is fixedly connected to the lifting door 13. When the lifting door 13 moves, it drives the two protrusions to slide in the sliding grooves 110, thereby ensuring the smooth movement of the lifting door 13. When the lifting door 13 descends, the spring dampers 12 shorten with the movement of the lifting door 13 and absorb the impact force of the descending lifting door 13 to prevent collision with the base 10.

[0055] like Figures 1 to 9 As shown:

[0056] The adjusting assembly 5 includes a second bidirectional threaded rod 50, a pair of U-shaped sliders 51, and a motor 52.

The top of the U-shaped sliders 51 is in contact with the top wall of the heating chamber 11, and the bottom of the U-shaped sliders 51 is rotatably mounted on the infrared irradiation lamps 14. The U-shaped sliders 51 are threadedly connected to the outer periphery of the second bidirectional threaded rod 50, and the thread grooves on the two U-shaped sliders 51 are in opposite directions. The motor 52 is fixedly connected to one end of the heating chamber 11, and the output shaft of the motor 52 passes through the side wall of the heating chamber 11 and is coaxially connected to one end of the second bidirectional threaded rod 50. When the motor 52 is energized, it drives the second bidirectional threaded rod 50 to rotate. Through the threaded transmission between the rod and the U-shaped sliders 51, the two U-shaped sliders 51 and the two infrared irradiation lamps 14 are moved closer to each other to a suitable position.

[0057] like Figures 1 to 9 As shown:

[0058] The distance adjustment assembly 5 also includes a distance measuring baffle 53. The top of the distance measuring baffle 53 is fixedly connected to one end of one of the U-shaped sliders 51, and the bottom of the distance measuring baffle 53 abuts against one of the clamping pieces 30. When the two U-shaped sliders 51 approach each other, the distance measuring baffle 53 moves along with one of the U-shaped sliders 51. When it moves to abut against the top of one of the clamping pieces 30, the infrared irradiation lamp 14 is in the optimal irradiation position, thus realizing that the position of the infrared irradiation lamp changes according to the size of the connecting plate.

[0059] like Figures 1 to 9 As shown:

[0060] The adjusting assembly 5 also includes a pair of bolts 54, which pass through and are threadedly connected to the bottom of the U-shaped slider 51, and pass through and are rotatably connected to the top of the infrared irradiator 14. The bolts 54 allow the infrared irradiator 14 to rotate at the bottom of the U-shaped slider 51, thereby aligning it with the flexible plate area of ​​the bonding plate.
