Description

Technical Field

[0001] This utility model relates to the field of bonding technology for display panels, and in particular to a feeding device. Background Technology

[0002] With advancements in industrial technology, the manufacturing processes for display devices are constantly improving. Currently, the LCD manufacturing industry involves multiple bonding processes. Whether it's a flexible panel or a rigid panel including a glass substrate, it requires bonding FPC or PCB wiring layers to connect external signal and driving circuits. Bonding refers to applying ACF (Anisotropic Conductive Film) adhesive between the panel (including flexible and rigid panels) and the FPC or PCB wiring layers, followed by bonding.

[0003] However, the temperature of the pressure head is too high and the pressure is too great during the pressing process. Therefore, Teflon or silicone sheet is usually used as a cushioning material and laid flat on the product before pressing. This process also creates new problems: the tension of the cushioning material is difficult to control, the material changing operation is inconvenient, the cushioning material is prone to misalignment, causing the cushioning material at the edge of the pressure head to droop and stick to the product, resulting in burns and poor pressing, and the material changing time is long.

[0027] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0028] The present invention provides a feeding device, comprising:

[0029] A bracket 1 is used to support the feeding unit, recycling unit, conveying unit, and detection unit; the feeding unit is equipped with a buffer material roll, and the buffer material is conveyed to the working position through the conveying unit and then to the recycling unit for recycling.

[0030] Please refer to the following: Figure 3 , Figure 4 In this embodiment, the feeding unit includes:

[0031] The outer cylinder 23 is equipped with a buffer material roll. The outer cylinder 23 has a second shaft flat position 230 on both sides of its surface. The second shaft flat position 230 has multiple limiting members 231. The limiting members 231 abut against the inner wall of the buffer material roll to prevent the buffer material roll from shaking. It can also be compatible with buffer material rolls of different diameters. The limiting members 231 are elastic springs.

[0032] The inner sides of the outer cylinder 23 are symmetrically provided with an upper friction ring 21 and a lower friction ring 22. The upper friction ring 21 and lower friction ring 22 have multiple positioning grooves. The upper friction ring 21 and lower friction ring 22 are connected by placing an elastic element 210 in the positioning groove. The symmetrical upper friction ring 21 and lower friction ring 22 are connected by a fixed shaft 20. The upper friction ring 21 and lower friction ring 22 are semi-circular in shape with a groove in the center. The fixed shaft 20 is placed in the groove. The fixed shaft 20 has a snap-fit ​​part 200 and first shaft flat parts 201 on both sides. The first shaft flat parts 201 extend... The bracket 1 is also provided with a snap-fit ​​groove 10 at the snap-fit ​​part 200. The snap-fit ​​part 200 of the fixed shaft 20 is snapped into the snap-fit ​​groove 10 of the bracket 1. The snap-fit ​​groove 10 is perpendicular to the groove at the center of the upper friction ring 21 and the lower friction ring 22. The fixed shaft 20 is fixed to the bracket 1. The elastic element 210 can perform the stretching movement to the maximum extent, so that the outer surfaces of the upper friction ring 21 and the lower friction ring 22 are completely abutted against the inner surface of the outer cylinder 23 and friction is generated between them. When the outer cylinder 23 carries the buffer material roll in a winding movement, a reaction force is generated to further tighten the buffer material.

[0033] Please refer to the following: Figure 1 , Figure 2 In this embodiment, the feeding unit includes an air blowing component 24, which is located below the buffer material roll. The air blowing component 24 is an adjustable air blowing rod with an adjustable rotation angle. The air blowing nozzle faces the surface of the buffer material it passes through, reducing the impact of excessively high temperature from the pressure head.

[0034] In this embodiment, the recycling unit includes a gear shaft 30 connected to the rear of the support 1. The surface of the gear shaft 30 is knurled to increase friction. The conveying unit includes a first spur gear 49 connected to the gear shaft 30 and extending to one side of the outer wall of the support 1. A second spur gear 41 is also provided diagonally above the first spur gear 49. The first spur gear 49 and the second spur gear 41 mesh with each other. The conveying unit also includes a power source 40 connected to the second spur gear 41. The power source 40 drives the gear shaft 30 to recycle the buffer material through the first spur gear 49 and the second spur gear 41.

[0035] A pressure roller shaft 31 is provided behind the gear shaft 30. The gear shaft 30 and the pressure roller shaft 31 are slidably connected. The buffer material is conveyed to the gap between the pressure roller shaft 31 and the gear shaft 30. The used buffer material can flow into the waste box through the guide plate. Guide shafts 32 are provided on both sides of the pressure roller shaft 31. The recycling unit also includes a connector 33 that connects the pressure roller shaft 31 to the bracket 1 and a sleeve embedded in the guide shaft 32. A telescopic component that can adjust the gap between the pressure roller shaft 31 and the gear shaft 30 is sleeved on the guide shaft 32. The sleeve is fixedly connected to the connector 33. A quick-release component 34 for adjusting the telescopic component is also provided behind the sleeve. The guide shaft 32, with the telescopic component, passes through the sleeve and is connected to the quick-release component 34. By moving the quick-release component 34 in the loosening direction, the degree of extension of the telescopic component is adjusted to make the gear shaft 30 and the pressure roller shaft 31 fully contact. Then, the quick-release component 34 is moved in a fixed direction to complete the adjustment of the contact space between the gear shaft 30 and the pressure roller shaft 31.

[0036] In this embodiment, the moving unit includes drawer rails 50 for the pull-out bracket 1. There are two sets of drawer rails 50, and the drawer rails 50 are connected to the bracket 1 by fixing plates 51. There are two fixing plates 51, and their ends are connected by a first connecting rod. When the bracket is pulled out, the ends of the fixing plates 51 are connected to increase stability. When the cushioning material is used up or a component needs adjustment, the operator can select any component according to the operating conditions and pull out the bracket 1 through the drawer rails 50 for quick material replacement or adjustment.

[0037] In this embodiment, the detection unit includes a first detection area for detecting the usage status of the buffer material, a second detection area for detecting whether the buffer material is cut, and a third detection area for detecting the pull-out status of the bracket 1. The first detection area includes a mounting plate and a sensor. The mounting plate is fixedly connected to the bracket 1. The sensor is located above the first guide rod 42 and the second guide rod 43. When the buffer material is used up, the first detection area can quickly sense whether there is buffer material at the first guide rod 42 and the second guide rod 43, and determine whether to issue an alarm to prompt material replacement based on the result. The second detection area is located above the fifth guide rod 46 and the sixth guide rod 47. The fifth guide rod 46 is close to the pressing area. When the pressing operation is performed, if the temperature is too high or the tension is excessive, the buffer material may break. At this time, the second detection area can quickly detect this and issue an alarm to suspend the pressing operation. The third detection area is located behind the bracket 1. When the bracket 1 is pulled out through the drawer guide rail 50 and then reset, the third detection area can quickly detect whether it has been fully reset. If the bracket 1 is not fully inserted, an alarm will be triggered.

[0038] In this embodiment, the first guide rod 42 and the second guide rod 43 are located behind the fixed shaft 20 and are parallel to each other; the third guide rod 44 is located behind the air blowing component 24 and is perpendicular to the second guide rod 43; the fourth guide rod 45 is located in the middle of the bracket 1 in the first direction; the fifth guide rod 46 and the sixth guide rod 47 are located behind the fourth guide rod 45 and in front of the gear shaft 30, with the fifth guide rod 46 being lower than the sixth guide rod 47; the third guide rod 44 and the fourth guide rod 45 can further fix the two sets of brackets 1, making the bracket 1 more stable; the third guide rod 44, the fifth guide rod 46, and the sixth guide rod 47 are each provided with two fixing sleeves 48 for fixing the flat-laid buffer material, and the buffer material of different widths can be adjusted through the fixing sleeves 48 to make the taut buffer material be in a uniform straight line; the buffer material is wound in such a way that the upper surfaces of the first guide rod 42, the second guide rod, the sixth guide rod 47, and the gear shaft 30 are wound around the lower surfaces of the third guide rod 44, the fourth guide rod 45, and the fifth guide rod 46, completing the process in a cross manner.
