A mobile phone screen protector

Abstract

A mobile phone screen bonding fixture includes a base with a placement groove, a frame next to the placement groove, pick-and-place slots on both sides of the placement groove, several pillars on the frame, an exhaust channel within the placement groove with an exhaust hole, an air extraction port on the outer side of the base, and a limiting protrusion on the outer side of the exhaust channel. The semi-circular cross-section and multi-branch design of the exhaust channel increase the contact area with the screen, ensuring even distribution of the adsorption force. Combined with the regular distribution of the limiting protrusion, it avoids FPC and ribbon cables, ensuring the screen remains fixed before bonding and preventing initial misalignment due to manual placement errors. The levitation force of the magnet maintains a 2-3 cm gap between the mid-frame and the screen, allowing for careful inspection of the corresponding positions of the screen and mid-frame before assembly, preventing misalignment and the need for re-bonding, thus reducing the risk of screen damage.

Description

Technical Field

[0001] This utility model relates to the field of mobile phone assembly, and in particular to a mobile phone screen attaching fixture. Background Technology

[0002] During the installation or refurbishment of foldable phones, the phone screen and the metal frame need to be bonded together. In this process, waterproof adhesive needs to be applied to the frame and aligned with the screen before bonding. However, in actual operation, the frame and screen may not be aligned before bonding. Directly removing the frame can damage the screen's FPC and ribbon cable. To solve the above problems, a mobile phone screen bonding fixture is proposed. Utility Model Content

[0003] The purpose of this invention is to solve the problem that right-facing screen mounting fixtures may not be able to fully adhere.

[0004] The present invention adopts the following technical solution:

[0005] A mobile phone screen-attaching fixture includes a base with a placement groove on the base, a frame next to the placement groove, pick-and-place slots on both sides of the placement groove, several columns on the frame, an exhaust channel inside the placement groove, an exhaust hole inside the exhaust channel, an air extraction port on the outside of the base, a limiting protrusion on the outside of the exhaust channel, and a magnet next to the limiting protrusion.

[0006] Furthermore, the placement slot is located in the middle of the upper surface of the base, the pick-up slot is located on the frame, the placement slot is higher than the pick-up slot, and is used to remove the mobile phone after the screen is attached. The columns on the frame are fixed by bolts, and columns are provided on the top, bottom, left and right sides of the frame. The columns are distributed in a rectangular shape on the frame.

[0007] Furthermore, the placement slot has a central axis in the middle and symmetrically arranged exhaust channels on both sides. The exhaust channels have a semi-circular cross-section and several parallel branches to increase the contact area with the mobile phone screen. The exhaust channels have exhaust holes at their ends that extend into the base. The base has an air passage, and the exhaust holes are connected to the air extraction interface through the air passage. The air extraction interface is connected to an external air extraction machine.

[0008] Furthermore, the limiting protrusions are rectangularly distributed in the placement groove, and several limiting protrusions are evenly distributed on the upper and lower sides of the placement groove. Several limiting protrusions are evenly arranged on the left side of the placement groove, and one limiting protrusion is arranged at each of the upper and lower ends of the right side. There is no limiting protrusion in the middle of the right side, which is used for the passage of the screen's FPC and ribbon cable.

[0009] Furthermore, the magnet is located between the limiting protrusion and the exhaust channel, and two larger magnets are respectively provided on the upper two sides of the placement groove, and several smaller magnets are respectively provided on the lower two sides for the suspension of the middle frame.

[0010] The beneficial effects of this utility model are:

[0011] The semi-circular cross-section and multi-branch design of the exhaust channel increases the contact area with the screen, making the adsorption force evenly distributed. Combined with the regular distribution of the limiting protrusions, it can avoid FPC and ribbon cable, ensuring that the screen is fixed in place before being attached to the screen, and avoiding initial misalignment caused by manual placement deviation.

[0012] By using the levitation force of magnets to maintain a 2-3 cm gap between the mid-frame and the screen, the corresponding positions of the screen and mid-frame can be carefully checked before assembly, avoiding misalignment and the need for re-gluing, thus reducing the risk of screen damage.

[0013] The placement slot is higher than the retrieval slot, making it easier to remove the phone from the side after the screen is attached; the distribution of the limiting protrusions and magnets perfectly matches the structure of the folding phone screen and the mid-frame, improving the accuracy of screen attachment.

[0022] This utility model provides a mobile phone screen-attaching fixture, including a base 1, a placement groove 2 on the base 1, a frame 3 next to the placement groove 2, pick-and-place grooves 4 on both sides of the placement groove 2, a plurality of columns 5 on the frame 3, an exhaust channel 6 inside the placement groove 2, an exhaust hole 7 inside the exhaust channel 6, an air extraction port 8 on the outside of the base 1, a limiting protrusion 9 on the outside of the exhaust channel 6, and a magnet 10 next to the limiting protrusion 9.

[0023] Furthermore, the placement slot 2 is located in the middle of the upper surface of the base 1, the pick-and-place slot 4 is located on the frame 3, the placement slot 2 is higher than the pick-and-place slot 4, and is used to remove the mobile phone after the screen is attached. The pillars 5 on the frame 3 are fixed by bolts. The frame 3 is provided with pillars 5 on the top, bottom, left and right sides, and the pillars 5 are distributed in a rectangular shape on the frame 3.

[0024] Furthermore, the middle of the placement groove 2 has a central axis, and there are symmetrically arranged exhaust channels 6 on both sides. The cross-section of the exhaust channel 6 is semi-circular. The exhaust channel 6 has several parallel branches to increase the contact area with the mobile phone screen. The end of the exhaust channel 6 is provided with an exhaust hole 7. The exhaust hole 7 extends into the base 1. The base 1 has an air passage. The exhaust hole 7 is connected to the air extraction interface 8 through the air passage. The air extraction interface 8 is connected to an external air extraction machine.

[0025] Furthermore, the limiting protrusions 9 are rectangularly distributed in the placement groove 2, and several limiting protrusions 9 are evenly distributed on the upper and lower sides of the placement groove 2. Several limiting protrusions 9 are evenly arranged on the left side of the placement groove 2, and one limiting protrusion 9 is arranged at the upper and lower ends of the right side. There are no limiting protrusions 9 in the middle of the right side, which is used for the FPC and ribbon cable of the screen to pass through.

[0026] Furthermore, the magnet 10 is located between the limiting protrusion 9 and the exhaust channel 6.

[0027] Working principle:

[0028] When in use, place the foldable phone screen on the placement slot 2 of the base 1, ensuring the screen is close to the limiting protrusions 9 on the left and top sides. This allows the FPC and ribbon cable on the right side of the screen to protrude from the right side of the placement slot 2. At this point, start the vacuum pump, extracting gas from the exhaust channel 6 through the vacuum port 8 and exhaust hole 7, creating a vacuum between the exhaust channel 6 and the screen. This suction fixes the screen in place. Then, lower the magnetic metal frame with waterproof adhesive from the rectangular pillars 5. Hold the frame and slowly lower it into the placement slot 4. The size of the frame should match the size of the rectangle formed by the pillars 5. As the frame descends, slowly release your grip. The magnet 10 in the placement slot 2 interacts with the magnetic frame, allowing it to suspend 2-3 cm above the screen. Use the camera to compare the positions of the screen and frame, ensuring they are aligned. Press down on the frame and assemble it with the screen using the waterproof adhesive. After assembly, remove the assembled screen and frame from the placement slot 4.
