Description
Technical Field
[0001] This utility model relates to the technical field of glass plate adhesive coating devices, and in particular to a glass cover plate adhesive coating device. Background Technology
[0002] Glass cover coating equipment is commonly used in the manufacturing process of touchscreens for devices such as smartphones and tablets. Its main purpose is to apply a uniform adhesive layer to the surface of the glass cover to facilitate the bonding of subsequent components such as display modules and touch modules. Glass covers are typically used as the outer layer of touchscreens. With the increasing demand for smart devices, the requirements for glass covers are becoming more stringent, especially in terms of drop resistance, scratch resistance, and optical performance. The main purpose of the coating process is to precisely apply an appropriate amount of adhesive to the surface of the glass cover, forming a uniform and bubble-free adhesive layer to ensure good adhesion and sealing between the glass cover and other modules (such as LCD and OLED panels).
[0003] Existing adhesive coating devices typically use a driven scraper to coat a release cover plate fixed to the surface of a material support mechanism. However, during the scraper's movement, the complexity of the drive mechanism and the motion inertia can easily lead to insufficient control precision in the amount of adhesive output, thus affecting the accuracy and uniformity of the adhesive layer thickness control.

The glue dispensing trough and the scraper are both located on the top side of the conveying mechanism. The glue dispensing trough is matched with the material support plate, the glue dispensing port extends along the top side plane of the material support plate, and the scraper is matched parallel to the glue dispensing port.
[0007] The coating mechanism also includes a drive assembly, which is mounted on the surface of the base plate and the output end of the drive assembly is correspondingly located on the top side of the material support plate; the glue dispensing trough and the scraper are respectively connected to the output end of the drive assembly.
[0008] In one embodiment, the conveying mechanism further includes a linear guide rail that extends along a preset glass cover conveying direction.
[0009] In one embodiment, the aforementioned material support plate is fitted onto the output end of the linear guide rail.
[0010] In one embodiment, the conveying mechanism further includes a plurality of first photoelectric switches, which are respectively disposed at preset positions on one side of the linear guide rail, and light-shielding members adapted to the first photoelectric switches are correspondingly installed at the output end of the linear guide rail.
[0011] In one embodiment, the aforementioned driving component further includes a first driving component, a second driving component, and a connecting base. The first driving component is disposed on the surface of the base plate; the connecting base is connected to the output end of the first driving component; and the second driving component is mounted on the connecting base.
[0012] In one embodiment, the aforementioned glue-dispensing groove is connected to the connecting seat.
[0013] In one embodiment, the aforementioned scraper is connected to the output end of the second drive component in conjunction with the glue dispensing port.
[0014] In one embodiment, the first drive assembly includes two mounting bases, two first guide rails, a first lead screw mechanism, and a drive plate. The two mounting bases are respectively disposed on opposite sides of the connecting base. The two first guide rails are respectively disposed on opposite surfaces of the two mounting bases. The first lead screw mechanism is disposed on a mounting base. One end of the drive plate is connected to the output end of the first lead screw mechanism, and the other end of the drive plate is connected to the connecting base.
[0015] In one embodiment, the two side surfaces of the connecting seat are slidably connected to the two first guide rails respectively.
[0016] In one embodiment, the first lead screw mechanism described above is configured as a manually operated lead screw mechanism controlled by a handwheel.
[0017] In one embodiment, the second driving assembly includes two second guide rails slidably fitted with slides, two second screw mechanisms, and a scraper seat. The two second guide rails are respectively disposed on both sides of the connecting seat. The two second screw mechanisms are respectively installed on the connecting seat corresponding to the two second guide rails. At the same time, the output end of each second screw mechanism drives the slide connected to the second guide rail. The two ends of the scraper seat are respectively connected to the slides of the two second guide rails.
[0018] In one embodiment, the aforementioned scraper is mounted on a scraper holder.
[0019] In one embodiment, the connecting seat is provided with two clearance grooves to match the moving range of the scraper seat, so that both ends of the scraper seat can extend through the two clearance grooves and connect to the slides of the two second guide rails.

[0023] The aforementioned glass cover plate adhesive coating device conveys the glass cover plate to be coated to the coating mechanism via a conveying mechanism. The output end of the coating mechanism outputs adhesive to the conveying end of the conveying mechanism. Thus, the glass cover plate receives the adhesive during the conveying process and works in conjunction with the output end of the coating mechanism to complete a uniform coating. Specifically, when the glass cover plate is placed on the top surface of the material support plate and moves back and forth there, the adhesive in the adhesive dispensing tank is output to the surface of the glass cover plate through the adhesive dispensing port. The scraper can precisely control the amount of adhesive output, thereby completing the quantitative adhesive coating process. Compared to existing glass plate coating equipment, the glass cover plate coating device of this invention uses a drive component to adjust the glue dispensing tank and scraper to a preset fixed position, and the glass cover plate is actively driven to move by the material support plate to achieve the coating process and obtain a glue layer of preset thickness. During this process, the glue dispensing tank and scraper do not need to move, thus ensuring the stability of the glue dispensing tank and scraper settings. The coating process can be completed by only the material support plate driving the glass cover plate, thereby avoiding system errors caused by the redundancy of the coating mechanism drive system, improving the uniformity of the glass cover plate coating and the controllability of the glue layer thickness.

[0033] Please see Figures 1 to 3This utility model discloses a glass cover plate adhesive coating device 10, which includes a base plate 100, a conveying mechanism 200, and a coating mechanism 300. The conveying mechanism 200 and the coating mechanism 300 are both installed on the surface of the base plate 100. The conveying mechanism 200 extends along a preset direction, and the coating mechanism 300 is disposed at one end of the conveying mechanism 200. The glass cover plate to be coated is conveyed to the coating mechanism 300 through the conveying mechanism 200. The output end of the coating mechanism 300 outputs adhesive to the conveying end of the conveying mechanism 200. Thus, the glass cover plate receives the adhesive during the conveying process and cooperates with the output end of the coating mechanism 300 to complete the uniform coating. Specifically, the conveying mechanism 200 includes a material support plate 210, which reciprocates along the conveying path of the conveying mechanism 200. Correspondingly, the coating mechanism 300 includes a dispensing trough 310 with a dispensing port a and a scraper 320. Both the dispensing trough 310 and the scraper 320 are located on the top side of the conveying mechanism 200. The dispensing trough 310 is correspondingly matched with the material support plate, the dispensing port a extends along the top side plane of the material support plate, and the scraper 320 is parallel to the dispensing port a. Thus, when the glass cover is placed on the top side surface of the material support plate 210 and reciprocates thereafter, the adhesive in the dispensing trough 310 is output to the surface of the glass cover through the dispensing port a, and the scraper 320 can precisely control the amount of adhesive output, thereby completing the quantitative coating process. More specifically, the coating mechanism 300 also includes a drive assembly, which is mounted on the surface of the base plate 100, and the output end of the drive assembly is correspondingly disposed on the top side of the material support plate 210; the glue dispensing tank 310 and the scraper 320 are respectively connected to the output end of the drive assembly, so that the drive assembly can drive the glue dispensing tank 310 and the scraper 320 to move to the preset working position, so that the glue dispensing port a and the scraper 320 can cooperate with the material support plate 210, thereby performing glue coating on the surface of the glass cover to obtain a uniform glue layer of preset thickness. Compared to existing glass plate coating equipment, the glass cover plate coating device 10 of this utility model adjusts the glue dispensing tank 310 and the scraper 320 to a preset fixed position through a drive component, and achieves the coating process by actively driving the glass cover plate to move through the material support plate 210 to obtain a glue layer of preset thickness. During this process, the glue dispensing tank 310 and the scraper 320 do not need to move, thereby ensuring the stability of the setting of the glue dispensing tank 310 and the scraper 320. The coating process can be completed by only the material support plate 210 driving the glass cover plate to move. This avoids the system error caused by the redundancy of the coating mechanism 300 drive system, and improves the uniformity of the glass cover plate coating and the controllability of the glue layer thickness.
[0034] Furthermore, the conveying mechanism 200 also includes a linear guide rail 220, which extends along a preset glass cover conveying direction. Based on this, a material support plate 210 is fitted at the output end of the linear guide rail 220, thereby enabling the linear guide rail 220 to drive the material support plate 210 to reciprocate along a preset direction, thus facilitating the conveying of the glass cover and the adhesive application process. In one embodiment, the conveying mechanism 200 also includes a plurality of first photoelectric switches 230, each disposed at a preset position on one side of the linear guide rail 220. A light-shielding element adapted to the first photoelectric switch 230 is correspondingly installed at the output end of the linear guide rail 220, i.e., on one side of the slide of the linear guide rail 220. This allows the plurality of first photoelectric switches 230 to detect the displacement of the slide of the linear guide rail 220, i.e., the material support plate 210. The coating mechanism 300 can adjust the relative position of the scraper 320 and the adhesive dispensing port a according to the movement state of the material support plate 210, thereby controlling the start and stop of the adhesive application process.
[0035] Furthermore, the drive assembly also includes a first drive assembly 330, a second drive assembly 340, and a connecting seat 350. The first drive assembly 330 is disposed on the surface of the base plate 100; the connecting seat 350 is connected to the output end of the first drive assembly 330; the second drive assembly 340 is mounted on the connecting seat 350; based on this, the glue dispensing tank 310 is connected to the connecting seat 350; and the scraper 320 is connected to the output end of the second drive assembly 340 in conjunction with the glue dispensing port a. Thus, the first drive assembly 330 can drive the glue dispensing tank 310, the second drive assembly 340, and the scraper 320 to move and adjust in a preset direction via the connecting seat 350. The second drive assembly 340 can drive the scraper 320 to move and adjust in a preset direction relative to the glue dispensing port a, so that the glue dispensing tank 310 and the scraper 320 can move to a suitable height in conjunction with the material support plate 210, and at the same time, the scraper 320 can adjust the output amount of adhesive to a preset value in conjunction with the glue dispensing port a.
[0036] Furthermore, the first drive assembly 330 includes two mounting seats 331, two first guide rails 332, a first lead screw mechanism 333, and a drive plate 334. The two mounting seats 331 are correspondingly disposed on both sides of the connecting seat 350; the two first guide rails 332 are respectively disposed on opposite surfaces of the two mounting seats 331; the first lead screw mechanism 333 is disposed on one mounting seat 331; one end of the drive plate 334 is connected to the output end of the first lead screw mechanism 333, and the other end of the drive plate 334 is connected to the connecting seat 350; based on this, the two side surfaces of the connecting seat 350 are slidably connected to the two first guide rails 332 respectively. Thus, the first lead screw mechanism 333 can drive the connecting seat 350 to reciprocate along the two first guide rollers in a preset direction via the drive plate 334, thereby realizing the position adjustment of the glue dispensing tank 310 and the scraper 320. In one embodiment, the first lead screw mechanism 333 is configured as a manual lead screw mechanism controlled by a handwheel.
[0037] Furthermore, the second drive assembly 340 includes two second guide rails 341 slidably fitted with slides, two second lead screw mechanisms 342, and a scraper holder 343. The two second guide rails 341 are respectively disposed on both sides of the connecting seat 350; the two second lead screw mechanisms 342 are respectively mounted on the connecting seat 350 corresponding to the two second guide rails 341, and the output end of each second lead screw mechanism 342 drives the slide connected to the second guide rail 341; both ends of the scraper holder 343 are respectively connected to the slides of the two second guide rails 341; based on this, the scraper 320 is mounted on the scraper holder 343. Thus, the second lead screw mechanism 342 can drive the scraper holder 343 to reciprocate in a preset direction by driving the slides of the second guide rails 341, thereby realizing the position adjustment of the scraper 320. In one embodiment, the connecting seat 350 is provided with two clearance grooves b to accommodate the movement range of the scraper seat 343, so that both ends of the scraper seat 343 can extend through the two clearance grooves b and connect to the slides of the two second guide rails 341. In another embodiment, the second lead screw mechanism 342 is configured as an electric lead screw mechanism.
[0038] Furthermore, each second guide rail 341 is provided with a second photoelectric switch 344. The second photoelectric switch 344 is located at a preset position on one side of the second guide rail 341. A light-shielding member adapted to the second photoelectric switch 344 is correspondingly installed on one side of the slide of the second guide rail 341, so that the second photoelectric switch 344 can detect the movement state of the slide of the second guide rail 341, i.e., the scraper 320.
[0039] Furthermore, the glue dispensing tank 310 is also equipped with a liquid level sensor 311, which is located on the top side of the glue dispensing tank 310 and connected to the connector 350 to monitor the amount of adhesive in the glue dispensing tank 310 in real time.
[0040] In summary, the glass cover plate adhesive coating device disclosed in this utility model conveys the glass cover plate to be coated to the coating mechanism via a conveying mechanism. The output end of the coating mechanism outputs adhesive to the conveying end of the conveying mechanism. Thus, the glass cover plate receives the adhesive during the conveying process and cooperates with the output end of the coating mechanism to complete uniform coating. Specifically, when the glass cover plate is placed on the top surface of the material support plate and moves back and forth there, the adhesive in the adhesive dispensing tank is output to the surface of the glass cover plate through the adhesive dispensing port, and the scraper can precisely control the amount of adhesive output, thereby completing the quantitative adhesive coating process. Compared to existing glass plate coating equipment, the glass cover plate coating device of this invention uses a drive component to adjust the glue dispensing tank and scraper to a preset fixed position, and the glass cover plate is actively driven to move by the material support plate to achieve the coating process and obtain a glue layer of preset thickness. During this process, the glue dispensing tank and scraper do not need to move, thus ensuring the stability of the glue dispensing tank and scraper settings. The coating process can be completed by only the material support plate driving the glass cover plate, thereby avoiding system errors caused by the redundancy of the coating mechanism drive system, improving the uniformity of the glass cover plate coating and the controllability of the glue layer thickness.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
