Description

Technical Field

[0001] The invention relates to the technical field of touch screen injection, and in particular to a touch screen glue injection device. Background Art

[0002] The touch screen full lamination process is to fill OCR (Optical Clear Resin) liquid glue or OCA (Optical Clear Adhesive) solid glue between the touch screen and LCM (LCD Module) / TP (Touchpanel), and the thickness of the glue is only 0.3mm-1mm. The injection process is to first apply dam glue and high-strength foam around the screen, and leave injection ports and exhaust ports, then position and laminate the touch screen and LCM / TP, and then inject low-viscosity OCR liquid glue from the injection ports reserved in advance.

[0003] Currently, the bonding equipment on the market can only bond small and medium-sized flat screens. For the bonding of curved and extra-large screens, the OCR liquid glue injection process is used, that is, a flexible needle is inserted at the glue injection port for glue injection.

[0004] However, the existing perfusion needles have the following problems when performing perfusion:

[0005] 1. Insert a flexible needle into the 0.3mm-1mm gap at the end of the touch screen's injection port. The injection port length is 1mm, and the injection cross-sectional area is 0.3mm2-1mm2. The injection speed is very slow and the efficiency is low.

[0006] 2. During the injection process, if the injection pressure of the needle is slightly increased, glue spraying will occur from the needle, affecting the injection effect.

[0007] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a touch screen glue injection device to make it more valuable for industrial use. Summary of the invention

[0008] The purpose of the present invention is to provide a touch screen glue injection device, which can improve the injection efficiency and avoid the glue spraying phenomenon.

[0009] To achieve this object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0030] like Figures 1 to 4 As shown, the touch screen glue injection device of the present invention includes a support platform 10, a plurality of positioning members 20 and a glue injection head 30. The support platform 10 has a support surface for supporting the touch screen, and a plurality of stoppers 17 are provided around the support surface on the support platform 10, and the touch screen is limited by each stopper 17. Each positioning member 20 is arranged on the support platform 10 and is located around the support surface. Preferably, the positioning member is a quick clamp. The glue injection head 30 is arranged on the support platform 10 and is located on one side of the support surface. The glue injection head 30 includes a block-shaped glue injection head body 31. The glue injection head body 31 is provided with a glue injection channel 32 running through both ends thereof. One end of the glue injection channel 32 can be connected to the glue injection port of the touch screen, and the other end can be connected to the glue injection tube 40. During glue injection, the glue injection tube 40 passes the OCR liquid glue into the glue injection channel 32, and the OCR liquid glue enters the glue injection port of the touch screen from the glue injection channel 32. It can be seen that the present invention utilizes the glue injection channel 32 to extend the glue injection head of the touch screen, increase the glue injection flow rate, and greatly improve the glue injection efficiency. The glue injection port of the touch screen is connected to the glue injection channel 32, and the glue injection channel 32 can avoid the glue spraying phenomenon at the glue injection port, thereby greatly improving the glue injection effect.

[0031] In order to further avoid the phenomenon of glue spraying at the glue injection port, the present invention is connected to the glue injection head body 31 with a pressing piece 50 that can press the glue injection end of the touch screen tightly against the support platform 10. The pressing piece 50 is also a quick clamp. After the glue injection port of the touch screen is docked with the glue injection channel 32, the pressing piece 50 is used to press the glue injection end of the touch screen tightly against the support platform 10 to seal the glue injection end of the touch screen and ensure the glue injection effect.

[0032] In addition, in order to enable the glue injection head 30 to support the glue injection end of the touch screen when the glue injection end of the touch screen is pressed, the present invention provides a step 33 on the end of the glue injection head body 31 for placing the glue injection end of the touch screen. When the glue injection end of the touch screen is pressed against the support platform 10, the step 33 can support the portion of the glue injection end of the touch screen that extends out of the support platform 10, so that the glue injection port of the glue injection end of the touch screen can dock with the glue injection channel 32.

[0033] In order to make the glue injection port of the touch screen well docked with the glue injection channel 32, the present invention provides a card slot 34 at the end of the glue injection port of the touch screen docked with the glue injection channel 32 on the glue injection head body 31, and the card slot 34 can hold the glue injection port of the touch screen. The card slot 34 can ensure that the glue injection port and the glue injection channel 32 are kept in a sealed state when docked.

[0034] Each positioning member 20 of the present invention is used to fix the touch screen to be injected with glue on the support platform 10. After the touch screen is fixed, the glue injection head 30 is docked with the glue injection port of the touch screen. In order not to affect the fixation and facilitate the docking, the glue injection head 30 of the present invention can reciprocate along the support platform 10 relative to the support surface. That is, after the touch screen is fixed, the glue injection head 30 moves to the glue injection end of the touch screen and docks with the glue injection port of the touch screen.

[0035] Specifically, in order to enable the glue injection head 30 to move, the present invention is provided with a notch 11 at one end of the support platform 10, and two parallel slide rails 12 are provided on the bottom surface of the support platform 10 on both sides of the notch 11, and a slide plate 13 is slidably connected between the two slide rails 12, and the glue injection head 30 is installed on the slide plate 13 and is located in the notch 11. The size of the notch 11 can meet the travel of the glue injection head 30.

[0036] In addition, a plurality of supporting feet 14 are provided on the bottom surface of the supporting platform 10, and the height of each supporting foot 14 is higher than the height of the slide rail 12. The supporting feet 14 are used to support the supporting platform 10 so as to place the supporting platform 10. Brackets 15 with a height higher than the supporting feet 14 may also be connected to both ends of the supporting platform 10, and the brackets 15 are rotatably connected with arc-shaped reinforcement members 16, and both ends of the reinforcement members 16 are fixed on the supporting platform 10. The brackets 15 are used to support the supporting platform 10 when the height supported by the supporting feet 14 is insufficient; the arc-shaped reinforcement members 16, on the one hand, enhance the bearing capacity of the brackets 15 on the supporting platform 10, and on the other hand, enable the supporting platform 10 to rotate with the connecting line of the two brackets 15 as the axis, so that the touch screen on the supporting platform 10 is in an inclined state, so that the liquid glue entering from the glue injection port can flow into the touch screen smoothly, further improving the glue injection efficiency.

[0037] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
