[0002] In the manufacturing process of super-large touch screens (usually over 75 inches, but also 98 inches and 110 inches), there is a process where, after the TP conductive film is attached to the glass cover, glue needs to be dispensed around the periphery of the TP conductive film. The conventional method of dispensing glue is to place the glass cover flat on a carrier and then transfer it to a dispensing device for dispensing glue. Due to the large size of the glass cover, the dispensing device and its conveyor belt (or conveying channel) occupy a large area. Moreover, this dispensing method is very inefficient. Generally, only one glass cover can be dispensed glue at the position of a dispensing device. Therefore, it is necessary to propose a new solution to the above problems. Summary of the invention

Glue dispensing: The needle tubes of multiple glue dispensing heads spaced side by side extend from the outer peripheral side of the glass cover plate to the edge of the corresponding TP conductive film. Afterwards, the needle tubes of the multiple glue dispensing heads move along the periphery of the TP conductive film to complete glue dispensing.

[0005] As a preferred solution, in step S2, four groups of glue dispensing mechanisms are used to dispense glue on the four edges of the TP conductive film simultaneously in the up, down, left and right directions.

[0006] In the second aspect, a batch dispensing device for manufacturing an ultra-large-size touch screen is applied to the batch dispensing method for manufacturing an ultra-large-size touch screen described in the first aspect, comprising a main frame and four groups of dispensing mechanisms arranged on the main frame, the four groups of dispensing mechanisms being arranged in the up, down, left and right directions corresponding to the four sides of the TP conductive film, each of the dispensing mechanisms comprising a dispensing bracket, a movable bracket, a movable driving mechanism, a telescopic driving mechanism and a plurality of dispensing heads; The mobile driving mechanism is connected to the mobile bracket to drive the mobile bracket to move back and forth along the direction of the corresponding edge of the TP conductive film. The telescopic driving mechanism is arranged on the mobile bracket and moves back and forth with the mobile bracket. The dispensing bracket is driven by the telescopic driving mechanism to telescope along the direction of approaching / moving away from the corresponding edge of the TP conductive film. Multiple dispensing heads are arranged side by side and spaced apart in the front-to-back direction on the dispensing bracket.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0017] See also Figures 1 to 8 The embodiment of the present invention provides a batch dispensing method for manufacturing an ultra-large-size touch screen, comprising the following steps: S1. Placing the glass cover plate 10 to be glued: multiple glass cover plates 10 are placed side by side and spaced apart on a carrier 20, wherein the carrier 20 does not cover the periphery of the TP conductive film on the glass cover plate 10, so that the needles of multiple glue dispensing heads 35 can extend from the outer peripheral side of the glass cover plate 10 to the edge of the corresponding TP conductive film; S2. Glue dispensing: The needle tubes of multiple glue dispensing heads 35 spaced side by side extend from the outer peripheral side of the glass cover plate 10 to the edge of the corresponding TP conductive film. Afterwards, the needle tubes of the multiple glue dispensing heads 35 move along the periphery of the TP conductive film to complete glue dispensing.

[0018] By placing the glass cover plate 10 upright on the carrier 20, the floor space occupied is greatly reduced compared to the traditional horizontal placement method. Multiple glass cover plates 10 are placed side by side and spaced apart, so that more workpieces to be glued can be accommodated in a limited space. Furthermore, multiple glue dispensing heads 35 work at the same time, so that multiple glass cover plates 10 can be glued at one time, which greatly improves the glue dispensing efficiency. Compared with the traditional single glue dispensing device that can only glue one glass cover plate 10 at a time, this batch glue dispensing method can significantly shorten the production cycle.

[0019] Furthermore, in step S2, four groups of dispensing mechanisms 30 are used to dispense glue on the four edges of the TP conductive film simultaneously in the up, down, left and right directions. Compared with the traditional single dispensing head 35 dispensing glue on the four edges in sequence, this synchronous dispensing on each edge can significantly improve production efficiency, which is especially critical for mass production of ultra-large touch screens.

[0020] The embodiment of the present invention also provides a batch dispensing device for manufacturing an ultra-large-sized touch screen, which is applied to the batch dispensing method for manufacturing an ultra-large-sized touch screen, including a main frame and four groups of dispensing mechanisms 30 arranged on the main frame, the four groups of dispensing mechanisms 30 corresponding to the four sides of the TP conductive film are arranged in the up, down, left and right directions, each of the dispensing mechanisms 30 includes a dispensing bracket 31, a mobile bracket 32, a mobile driving mechanism 33, a telescopic driving mechanism 34 and a plurality of dispensing heads 35; the mobile driving mechanism 33 is connected to the mobile bracket 32 ​​so as to drive the mobile bracket 32 ​​along the TP conductive film The telescopic driving mechanism 34 is arranged on the mobile bracket 32 ​​and moves back and forth with the mobile bracket 32. The dispensing bracket 31 is driven by the telescopic driving mechanism 34 to be telescopic in the direction close to / away from the corresponding edge of the TP conductive film. A plurality of dispensing heads 35 are arranged side by side and spaced apart in the front-to-back direction on the dispensing bracket 31. Through the coordinated work of four groups of dispensing mechanisms 30, multiple super-large touch screens can be dispensed at the same time, which greatly improves the production efficiency. The arrangement of multiple dispensing heads 35 makes the dispensing speed faster and can meet the needs of mass production.

[0021] Furthermore, each of the dispensing heads 35 is connected to the movable bracket 32 ​​via a connecting piece 36, and the movable bracket 32 ​​is provided with a first waist-shaped hole 321 extending in the front-to-back direction, and each of the connecting pieces 36 is connected to the first waist-shaped hole 321 via a screw, and each of the connecting pieces 36 is provided with a second waist-shaped hole 361 extending in the direction approaching / moving away from the TP conductive film, and each of the dispensing heads 35 is locked and connected to the second waist-shaped hole 361 via a screw. By setting the first waist-shaped hole 321 and the second waist-shaped hole 361, the dispensing head 35 can be flexibly adjusted in the front-to-back direction and in the direction approaching / moving away from the TP conductive film. This design can adapt to extra-large touch screens of different sizes and different dispensing requirements, thereby improving the versatility and adaptability of the device.

[0022] The embodiment of the present invention also provides a carrier 20 for manufacturing an ultra-large-sized touch screen, which is applied to the batch dispensing device for manufacturing an ultra-large-sized touch screen, and includes a main body 21 and a plurality of partition plates 22. The main body 21 includes a bearing frame 23 and a side frame 24. The side frame 24 is vertically arranged at one side of the bearing frame 23. A caster 25 is arranged at the bottom of the bearing frame 23. A lower fixing structure 40 for fixing the bottom of the glass cover plate 10 is arranged on the bearing frame 23. An upper fixing structure 50 for fixing the top of the glass cover plate 10 is arranged on the top of the side frame 24. Support portions 221 are convexly provided at the four corners of each of the partition plates 22. Along the circumference of the partition plate 22, a needle for the dispensing head 35 is formed between two adjacent support portions 221. The activity space for the pipe to enter and exit, the carrier 20 has casters 25, can move freely, and is convenient for being transferred to or removed from the dispensing device. It should be noted that a structure for stopping and positioning the carrier 20 can be designed at the dispensing device, such as designing two relatively arranged L-shaped columns, so that the two L-shaped corners of the supporting frame 23 of the carrier 20 can be correspondingly inserted between the two L-shaped columns to achieve positioning. In addition, there can be other stopping and positioning methods, such as magnetic suction or pin-to-pin matching jack methods, which are not limited; of course, the carrier 20 can also be used in conjunction with a transmission track.

[0023] Furthermore, the lower fixing structure 40 includes a pressing bar 41 for pressing the bottom of the glass cover plate 10 and a screw 42 for controlling the pressing bar 41 to move closer to / away from the side frame 24. The pressing bar 41 is arranged opposite to the side frame 24. The pressing bar 41 presses the bottom of the glass cover plate 10 and works together with the side frame 24 to keep the glass cover plate 10 in a stable upright state on the carrier 20. By screwing the screw 42, the pressing bar 41 can be controlled to move closer to or away from the glass cover plate 10, which enables the carrier 20 to adapt to glass cover plates 10 of different thicknesses, thereby improving the versatility of the carrier 20.

[0024] Furthermore, the upper fixing structure 50 includes two groups of clamping assemblies, each group of clamping assemblies is respectively arranged at the two ends of the top of the side support frame 24, each clamping assembly includes a clamping arm 51, a clamping member 52, and a screw bolt 53.
