Description

Technical Field

[0001] This utility model belongs to the technical field of membrane bonding equipment, specifically relating to a membrane pressing tool. Background Technology

[0002] In existing production processes, pressure is a crucial factor in film lamination, requiring pressure to activate the film. When laminating the film onto the main control board of the display screen, the film needs to be held under pressure for a certain period to ensure activation. Proper pressure holding balances the surface energy difference between the film and the substrate, preventing uneven pressure distribution due to varying material hardness, thus improving bonding strength and long-term stability. To ensure stable film adhesion, the optimal pressure holding method needs to be tested. However, commonly used methods, such as using spring-loaded clamping fixtures, cannot accurately control the pressure; motor-driven clamping equipment is expensive and unsuitable for pressure holding during the development and verification phase. Utility Model Content

[0003] The present invention aims to provide a membrane pressing tool to solve the problems of existing pressing equipment being unable to accurately control the pressing force or being too expensive.

[0004] To achieve the above objectives, the present invention comprises: a carrier platform, a frame fixed on the carrier platform, a moving mechanism mounted on the frame, and a pressing mechanism for maintaining pressure on the membrane material. The moving mechanism is used to adjust the position of the pressing mechanism. The pressing mechanism is located above the carrier platform and includes a mounting platform and a guide column. The guide column is mounted on the mounting platform and can slide along the mounting platform. The lower end of the guide column extends out of the mounting platform and can contact the product on the carrier platform. The upper end of the guide column is used to place a pressure-adding component to increase weight.

[0005] The working principle and beneficial effects of this solution are as follows: When testing the pressure holding requirements of the membrane material, the membrane material is first manually adhered to the product PCB board, then the PCB board is placed on the carrier, and finally the carrier is fixed on the carrier platform. The moving mechanism is operated, which drives the pressing mechanism to move towards the PCB board. When the lower end of the guide post contacts and adheres to the PCB board, the moving mechanism is stopped; the position of the guide post remains unchanged. The pressure-applying component is placed on the upper end of the guide post, and the pressure from the component is applied to the PCB board through the guide post, resulting in better adhesion between the PCB board and the membrane material.

[0006] In this solution, the pressing force can be adjusted by replacing the pressure components of different weights, which is simple and convenient, and the difference in pressing force can be controlled to within 0.01g. Furthermore, the overall design of this solution does not utilize pneumatic or electrical components, making it suitable for a wide range of environments. Moreover, since it does not use pneumatic valves or electrical modules, the overall cost is low, making it suitable for the research and development verification stage.

[0007] Optionally, the upper part of the guide post is placed on the mounting platform, and the lower part of the guide post is slidably connected to the mounting platform. With this configuration, when no upward force is applied to the guide post, the guide post is engaged on the mounting platform, and the movement of the mounting platform can drive the guide post to move together; when the guide post moves to contact the PCB board, the guide post is no longer attached to the mounting platform, and the weight of the mounting platform will not be applied to the PCB board.

[0008] Optionally, the lower end of the guide post is provided with a rubber-coated head. The rubber-coated head can effectively protect the product in contact with the guide post from damage, and at the same time, it can ensure that the pressure is evenly transmitted to the membrane material and the product.

[0009] Optionally, the mounting platform is equipped with multiple guide pillars. Each guide pillar can perform a pressure holding test on the membrane material once, and the multiple guide pillars on the mounting platform can effectively improve the efficiency of the membrane material pressure holding test.

[0010] Optionally, the frame is provided with a guide rod, and the mounting platform passes through the guide rod and is slidably connected to the guide rod. The guide rod effectively ensures that the movement of the mounting platform meets actual needs.

[0011] Optionally, the moving mechanism includes a handle, a connecting rod, a slide cylinder fixed to the frame, and a slide bar slidably connected to the slide cylinder. One end of the connecting rod is hinged to the handle, and the other end of the connecting rod is hinged to the upper end of the slide bar. The lower end of the slide bar is connected to the mounting platform. One end of the handle is hinged to the frame. The moving mechanism of this solution is essentially a connecting rod pressing mechanism, which has a simple structure. The position of the slide bar can be controlled by operating the handle, thereby adjusting the position of the mounting platform, making operation simple and convenient.

[0012] Optionally, the mounting platform includes an upper mounting plate and a lower mounting plate, with multiple connecting rods fixed between the upper and lower mounting plates; the upper mounting plate has a guide groove for the upper part of the guide post to slide upward, and the lower mounting plate has a through hole for the lower part of the guide post to slide upward.

[0013] Optionally, the pressure-applying component is a weight. Attached Figure Description

[0014] Figure 1 This is a structural diagram of a membrane pressing tool according to the present invention. Detailed Implementation

[0015] The following detailed description illustrates the specific implementation method:

[0016] The reference numerals in the accompanying drawings include: vehicle platform 10, frame 20, guide rod 21, linear bearing 22, guide column 30, weight 31, rubber-coated head 32, upper mounting plate 40, lower mounting plate 41, handle 50, connecting rod 51, slide cylinder 52, and slide bar 53.

[0017] This embodiment is basically as follows: Figure 1 As shown: A membrane pressing fixture includes a frame 20, a carrier platform 10, a pressing mechanism, and a moving mechanism mounted on the frame 20. The frame 20 is welded to the carrier platform 10. The pressing mechanism is used to maintain pressure on the membrane material and is located above the carrier platform 10.

[0018] The pressing mechanism includes a mounting platform and guide posts 30. The guide posts 30 are mounted on the mounting platform and can slide along it. In this embodiment, the upper part of the guide post 30 is cylindrical, and the lower part is cuboid. The cross-sectional area of ​​the upper part of the guide post 30 is larger than that of the lower part. The upper part of the guide post 30 is placed on the mounting platform, and the lower part is slidably connected to the mounting platform. The mounting platform in this embodiment includes an upper mounting plate 40 and a lower mounting plate 41. Four connecting rods are integrally fixed between the upper mounting plate 40 and the lower mounting plate 41, and the four connecting rods are located at the four ends of the upper mounting plate 40. The upper mounting plate 40 has a guide groove for the upper part of the guide post 30 to slide upward, and the lower mounting plate 41 has a through hole for the lower part of the guide post 30 to slide upward. The lower end of the guide post 30 extends out of the lower mounting plate 41 and can contact the product on the carrier platform 10. The lower end of the guide post 30 is provided with a rubber-coated head 32, which effectively protects the product in contact with the guide post 30 from damage and also ensures that pressure is evenly transmitted to the membrane material and the product. The upper end of the guide post 30 is used to place a pressure-pressuring component to increase weight; in this embodiment, the pressure-pressuring component is a weight 31. One, two, or more guide posts 30 can be set on the mounting platform. Each guide post 30 is independent and can perform a pressure-holding test on the membrane material once. Setting multiple guide posts 30 can effectively improve the efficiency of the membrane material pressure-holding test. In this embodiment, there are four guide posts 30.

[0019] The moving mechanism is used to adjust the position of the pressing mechanism, enabling it to move linearly to one side of the carrier platform 10. Many specific structures can achieve the function of the moving mechanism in this solution; this embodiment specifically adopts the following scheme: The moving mechanism includes a handle 50, a connecting rod 51, a slide cylinder 52, and a slide bar 53. The slide cylinder 52 is welded to the frame 20, and the slide bar 53 is slidably connected to the slide cylinder 52. The lower end of the slide bar 53 is welded to the upper mounting plate 40. In this embodiment, the handle 50 is generally L-shaped, with one end hinged to the frame 20. One end of the connecting rod 51 is hinged to the handle 50, and the other end is hinged to the upper end of the slide bar 53. Pressing the handle 50 transmits the force of the handle 50 to the slide bar 53 through the connecting rod 51, allowing the slide bar 53 to move along the slide cylinder 52.

[0020] Guide rods 21 are welded to both the left and right sides of the platform 10, with the upper ends of the guide rods 21 welded to the frame 20. Linear bearings 22 are fixedly mounted on the lower mounting plate 41, through which the guide rods 21 pass. The lower mounting plate 41 is slidably connected to the guide rods 21 via the linear bearings 22. The guide rods 21 ensure that the entire mounting platform can only move up and down in a straight line along the guide rods 21, guaranteeing that the movement of the mounting platform meets actual requirements.

[0021] When testing the pressure holding requirements of the membrane material, first manually attach the membrane material to the product PCB board, then place the PCB board on the carrier, and finally fix the carrier on the carrier platform 10. Press down on the handle 50. The handle 50 transmits the force to the slide bar 53 through the connecting rod 51, causing the slide bar 53 to move the upper mounting plate 40 and the lower mounting plate 41 downwards together. When the lower end of the guide post 30 contacts and adheres to the PCB board, stop the handle 50. At this time, the position of the guide post 30 will not change. Place the weight 31 on the upper end of the guide post 30. The pressure of the weight 31 is applied to the PCB board through the guide post 30, allowing the PCB board and the membrane material to adhere better. By changing different weights of the weight 31, the optimal adhesion pressure of the membrane material can be tested.

[0022] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
