Detailed Implementation
[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0021] like Figures 1 to 3As shown, this utility model provides a dual-action film-tearing platform, including a support 100, on one side of which a film-tearing platform 120 is positioned. The film-tearing platform 120 includes a movable frame 121, a fixed frame 122 and a positioning part 124. There are two positioning parts 124. One positioning part 124 is fixed on the movable frame 121, and the other positioning part 124 is fixed on the fixed frame 122. That is to say, it is possible to perform film peeling operations on multiple liquid crystal glass at the same time. The positioning unit 124 is capable of positioning liquid crystal glass of various shapes.
[0022] Specifically, such as Figures 1 to 5 As shown, each of the positioning parts 124 includes a vacuum stage 1241. The vacuum stage 1241 is hollow inside and has multiple air holes evenly opened on the top. A vent pipe 1245 is fixed on its side. The vent pipe 1245 is connected to a vacuum pump through a pipe. The vacuum pump is fixed on the bracket 100. One vacuum stage 1241 is fixed to the top of the movable frame 121, and another vacuum stage 1241 is fixed to the top of the fixed frame 122; Each vacuum stage 1241 has a placement plate 1242. Negative pressure airflow can be generated in the vent holes to adsorb the placement plate 1242. The placement plate 1242 is in contact with the top of the vacuum stage 1241. The placement plate 1242 is located above multiple vent holes, and the multiple vent holes can cover the area of the placement plate 1242.
[0023] It is easy to understand that by using a vacuum pump to draw air into the vent pipe 1245, the air inside the vacuum stage 1241 is extracted, creating a negative pressure airflow in the vent hole, which tightly adheres the placement plate 1242 to the vacuum stage 1241, thus fixing the placement plate 1242 in place.
[0024] Specifically, such as Figures 1 to 5 As shown, each of the placement plates 1242 has a rectangular groove in the upper center, and a positioning hole 1243 is formed in the center of the rectangular groove. Each of the rectangular slots of the placement plate 1242 has a circular positioning hole 1244 located away from the positioning hole 1243. The negative pressure airflow generated in the vent can enter the positioning hole 1243 and the positioning hole 1244. The positioning hole 1243 and the positioning hole 1244 are far apart, so even if no liquid crystal glass is placed at the positioning hole 1243, it will not affect the film removal operation of the liquid crystal glass at the positioning hole 1244.
[0025] It is worth noting that rectangular grooves can accommodate LCD glass of rectangular, circular, trapezoidal, and irregular shapes, with an area smaller than or equal to that of the rectangular groove. Positioning hole 2 1244 is used to adsorb smaller circular LCD glass. When a smaller LCD glass is placed on positioning hole 2 1244, positioning hole 1 1243 can also accommodate a smaller LCD glass. The LCD glass at positioning hole 1 1243 and positioning hole 2 1244 do not affect each other, allowing one placement plate 1242 to hold two LCD glasses, increasing the film removal efficiency. When the LCD glass is larger, it will cover positioning hole 1 1243 and positioning hole 2 1244. At this time, positioning hole 1 1243 and positioning hole 2 1244 simultaneously adsorb a larger LCD glass.
[0026] In the above embodiment, the liquid crystal glass is placed on the positioning holes 1244 on the two placement plates 1242 by a loading robot, and air is drawn into the vent pipe 1245 by a vacuum pump to extract the air in the vacuum stage 1241, so that negative pressure airflow is generated in the vent hole to position the liquid crystal glass on the positioning hole 1244. Then, the protective film on the liquid crystal glass is removed by the film peeling mechanism. It can simultaneously peel the film off multiple liquid crystal glasses and can adapt to the positioning of liquid crystal glasses of various shapes, thereby improving the efficiency of product processing and increasing the utilization rate of equipment. In some embodiments of this application, considering that when peeling the film off a narrow strip of liquid crystal glass, due to its excessive length and narrow width, increasing the length of the vacuum stage 1241 and the placement plate 1242 for a single shape would not only result in high costs but also limit the length of the narrow strip that can be accommodated, affecting product processing efficiency, further improvements are made to address the above problems. Specifically, such as Figures 3 to 5 As shown, each vacuum stage 1241 has a hollow air inlet seat 1248 fixed on its side. A suction nozzle 1249 is fixed on the air inlet seat 1248. The suction nozzle 1249 communicates with the interior of the air inlet seat 1248 and is parallel to the positioning hole 1244. In other words, when the liquid crystal glass is placed on the rectangular groove and the suction nozzle 1249, the flatness of the liquid crystal glass can be guaranteed and it is not easy to cause bending of the liquid crystal glass. A vacuum tube is fixed on the air inlet seat 1248 at a distance away from the vacuum stage 1241. The air inlet end of the vacuum tube is connected to the vacuum pump, and a valve is fixed on the vacuum tube. The valve is used to control the opening and closing of the airflow in the vacuum tube.
[0027] It should be noted that when the film is not removed from the narrow strip of liquid crystal glass, or when the length of the liquid crystal glass does not exceed the range of the placement plate 1242, the valves on the vacuum tube are in the closed state. When the film is removed from the narrow strip of liquid crystal glass, the valves on the vacuum tube are opened.
[0028] Specifically, such as Figures 3 to 5As shown, each vacuum stage 1241 has two parallel fixing plates 1246 fixed at the bottom near the air inlet seat 1248, and each fixing plate 1246 has a sliding groove. An adjusting plate 1247 is positioned between the fixed plates 1246, and sliders that cooperate with the sliding groove are fixed on both sides of the adjusting plate 1247. The air intake seat 1248 is fixed on the adjustment plate 1247.
[0029] Specifically, such as Figures 3 to 5 As shown, the adjusting plate 1247 can move between the fixed plates 1246 to adjust the distance between the air inlet seat 1248 and the placement plate 1242. In other words, by adjusting the position of the air inlet seat 1248, it can adapt to the positioning of narrow strip LCD glass of various lengths.
[0030] Specifically, such as Figures 3 to 5 As shown, each of the placement plates 1242 is fixed with a support plate 1250 near the air inlet seat 1248. The support plate 1250 is used to support the liquid crystal glass, and the support plate 1250 and the suction nozzle 1249 are staggered. When the liquid crystal glass is placed on the suction nozzle 1249, the liquid crystal glass can contact the support plate 1250.
[0031] It is easy to understand that by using the support plate 1250 to support the narrow strip of liquid crystal glass, the contact area with the liquid crystal glass is increased, thus ensuring the stability of the film removal process.
[0032] Based on the above embodiments, before peeling the film off the narrow and elongated liquid crystal glass, the distance between the adjustment plate 1247 and the placement plate 1242 is adjusted according to the length of the liquid crystal glass. After adjusting to a suitable position, the liquid crystal glass is fed. After the liquid crystal glass is placed on the placement plate 1242, one end of the liquid crystal glass is located above the suction nozzle 1249. The valve of the vacuum tube is opened, and the negative pressure airflow generated by the positioning hole 1243, the positioning hole 21244 and the suction nozzle 1249 adsorbs the liquid crystal glass. This can achieve positioning of narrow and elongated liquid crystal glass of various lengths, reduce the cost of use and improve the processing efficiency.
[0033] In some embodiments of this application, considering the different distances between the liquid crystal glass feeding gripper and the robotic arm of the film-tearing mechanism, the distance between the two stations needs to be adjusted after feeding. Manual adjustment is inefficient and affects subsequent processing efficiency. Therefore, further improvements are made to address the above problems. Specifically, such as Figures 1 to 5 As shown, the film-tearing platform 120 also includes a base 123, a guide rail is fixed on the bracket 100, the base 123 is positioned on the guide rail, and a drag chain 110 is fixed on the side of the bracket 100. The drag chain 110 is used to drive the base 123 to move at the guide rail. The fixed frame 122 is fixed on the base 123. A guide rod 126 is fixed on the base 123 away from the fixed frame 122. A movable seat 1211 is sleeved on the guide rod 126. The movable seat 1211 can move on the guide rod 126. The movable frame 121 is fixed on the movable seat 1211.
[0034] Specifically, such as Figures 3 to 5 As shown, a drag chain 125 is fixed to the side of the base 123. The drag chain 125 is used to drive the movable seat 1211 to move on the guide rod 126.
[0035] Specifically, such as Figures 3 to 5 As shown, a mounting bracket 140 is positioned on the side of the bracket 100 away from the film-tearing platform 120. The mounting bracket 140 is positioned on the guide rail. Two intermediate alignment platforms 141 are fixed on the mounting bracket 140. A drag chain 3 130 is fixed on the bracket 100 near the mounting bracket 140. The drag chain 3 130 can drive the mounting bracket 140 to move on the guide rail.
[0036] It should be noted that after the film is removed from the LCD glass, the LCD glass needs to be placed on the transfer alignment platform 141 by a material unloading robot for subsequent processing of the LCD glass.
[0037] Based on the above embodiments, before loading, the moving frame 121 is driven closer to the fixed frame 122 by the second drag chain 125 to reduce the distance between the two. After loading, the moving frame 121 is driven away from the fixed frame 122 by the second drag chain 125. At the same time, the film-tearing platform 120 is driven closer to the film-tearing mechanism by the first drag chain 110. After the film is torn by the film-tearing mechanism, the film-tearing platform 120 is driven closer to the transfer alignment platform 141 by the first drag chain 110. At the same time, the transfer alignment platform 141 is driven closer to the film-tearing platform 120 by the third drag chain 130 to improve the transfer efficiency. The unloading robot places the film-teared liquid crystal glass on the transfer alignment platform 141 to realize the film-tearing and transfer of the liquid crystal glass. The operation is fully automated and highly efficient.
