Description

Technical Field

[0001] The utility model belongs to the technical field of mobile phone accessory processing, and in particular relates to a feeding device and curved surface screen pasting equipment. Background Art

[0002] Curved screen mobile phones are becoming more and more prominent in the mobile phone industry, becoming high-end models that are highly sought after and sought after. In the manufacturing process of curved screens, the full bonding technology of optical adhesive film (OCA) and mobile phone cover is widely used to provide more excellent visual effects and tactile experience.

[0003] The OCA full-bonding equipment currently used usually adopts a single-station processing. First, the optical film and the mobile phone cover are simultaneously loaded onto the mold through the loading structure. Specifically, the optical film is loaded onto the upper mold base of the mold, and the mobile phone cover is loaded onto the lower mold base of the mold. The optical film and the mobile phone cover are then bonded by closing the mold.

[0004] However, in order to improve the degree of adhesion between the optical film and the mobile phone cover, the mold generally needs to be pressed for a period of time after the mold is closed. During the pressure holding process, the feeding structure is often in an idle waiting state. If multiple molds are set, the size of the feeding structure needs to be increased so that its feeding range covers each mold, which leads to increased costs and excessive space occupied by the overall equipment.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0032] See also Figures 1 to 3, the embodiment of the present application provides a feeding device 100 for feeding a first sheet and a second sheet, and the feeding device 100 has a pre-laminating station 104. The feeding device 100 is used to pre-laminate the first sheet with the second sheet, and then transfer the pre-laminated first sheet and second sheet to a predetermined position. In the embodiment of the present application, the first sheet is a cover plate on a mobile phone, and the second sheet is an OCA film (optical adhesive film sheet). The feeding device 100 can pre-laminate the optical adhesive film sheet and the cover plate, thereby facilitating the subsequent pressure maintenance of the optical adhesive film sheet and the cover plate.

[0033] See also Figures 1 to 3 The feeding device 100 includes a first feeding structure 101, a second feeding structure 102 and a transfer structure 103. The first feeding structure 101 is used to convey the first material sheet to the pre-lamination station 104, that is, the first material sheet is flatly conveyed to the pre-lamination station 104 for picking up by the transfer structure 103. The transfer structure 103 can absorb the first material sheet by vacuum negative pressure, lift it upward and move it horizontally to the second material sheet.

[0034] See also Figures 1 to 3 The second feeding structure 102 is used to convey the second material sheet to the pre-lamination station 104. The second feeding structure 102 includes a slidably arranged feeding seat 1021, an adsorption plate 1022 located on the feeding seat 1021 and provided with the second material sheet, and a driving mechanism 1023 for driving the feeding seat 1021 to slide back and forth relative to the pre-lamination station 104. It can be understood that a plurality of adsorption holes are provided on the adsorption plate 1022, and each adsorption hole is connected to a vacuum pump, so that the second material sheet can be adsorbed and positioned by means of vacuum negative pressure. The driving mechanism 1023 drives the feeding seat 1021 with the second material sheet placed thereon toward the pre-lamination station 104. After the feeding seat 1021 slides to the pre-lamination station 104, the material transfer structure 103 moves the first material sheet to be directly above the second material sheet, and presses the first material sheet downward toward the second material sheet, so that the first material sheet is pre-laminated with the second material sheet on the adsorption plate 1022, and the pre-laminated first and second materials are separated from the adsorption plate 1022 as a whole, thereby completing the pre-lamination of the first and second materials and realizing the subsequent synchronous loading of the first and second materials, which is beneficial to improving the loading efficiency of the first and second materials. In addition, the synchronous loading of the first and second materials can reduce the space occupied by the loading device 100 and reduce the cost.

[0035] See also Figures 1 to 3The loading device 100 provided in the embodiment of the present application first pre-laminates the first sheet and the second sheet, and then moves the pre-laminated first sheet and the second sheet as a whole to the rear mold, and performs full lamination and pressure holding through the mold, so that the loading and pressure holding of the first sheet and the second sheet can be carried out separately, and because the first sheet and the second sheet are loaded onto the mold simultaneously, the space occupied by the loading device 100 can be reduced, the structure of the loading device 100 can be simplified, and the cost of the loading device 100 can be reduced.

[0036] See also Figures 1 to 3 In some embodiments, the adsorption plate 1022 is slidably connected to the feeding seat 1021 in the vertical direction and is provided with a positioning groove 1025. The second feeding structure 102 also includes a positioning plate 1024 arranged in the positioning groove 1025 and connected to the feeding seat 1021. The positioning plate 1024 is provided with a positioning adsorption hole 1026 for adsorbing the second material sheet.

[0037] See also Figures 1 to 3 Optionally, when the first sheet is located above the second sheet, the adsorption plate 1022 moves downward relative to the positioning plate 1024 by a certain distance, such as 2mm or 5mm, which is not limited here and can be selected according to actual conditions. When the adsorption plate 1022 descends, the adsorption plate 1022 releases the adsorption force on the second sheet. At this time, the positioning plate 1024 rises relative to the adsorption plate 1022 and positions the second sheet through the positioning adsorption hole 1026. The transfer structure 103 presses the first sheet and the second sheet downward, thereby completing the pre-lamination of the first sheet and the second sheet, so as to facilitate the subsequent overall removal of the first sheet and the second sheet from the second feeding structure 102. It can be understood that the pre-lamination position is located in the middle of the first sheet or the second sheet, so as to avoid the existence of bubbles between the first sheet and the second sheet.

[0038] After the pre-lamination of the first sheet and the second sheet is completed, the adsorption plate 1022 rises and supports the second sheet, and the material transfer structure 103 moves the first sheet and the second sheet as a whole and synchronously away from the second feeding structure 102 to allow the subsequent pressure-maintaining operation to continue.

[0039] See also Figures 1 to 3 In some embodiments, the second feeding structure 102 also includes a lifting driver 1028 connected to the feeding seat 1021 and a support frame 1029 connected to the lifting driver 1028, the support frame 1029 is connected to the adsorption plate 1022, and the support frame 1029 is provided with an avoidance groove 293 corresponding to the position of the positioning plate 1024.

[0040] See also Figures 1 to 3Optionally, the lifting driver 1028 is a cylinder, which is usually a linear actuator that can generate linear motion by inputting gas (usually compressed air). The lifting driver 1028 can drive the adsorption plate 1022 to reciprocate in the vertical direction, thereby cooperating with the pre-lamination of the first sheet and the second sheet. The feeding seat 1021 has a receiving chamber 211, and the lifting driver 1028 is located in the receiving chamber 211. The lower end of the support frame 1029 is connected to the piston rod of the lifting driver 1028, and the upper end of the support frame 1029 is connected to the adsorption plate 1022, and the positioning plate 1024 is partially located in the avoidance groove 293, so that when the support frame 1029 drives the adsorption plate 1022 to reciprocate and lift, it will not interfere with the positioning plate 1024.

[0041] Optionally, the positioning adsorption holes 1026 on the positioning plate 1024 are also connected to the vacuum pump, and adsorb and position the second sheet through the negative pressure principle.

[0042] See also Figures 1 to 3 In some embodiments, the support frame 1029 includes a support base plate 292 connected to the lifting drive 1028 and a support side plate 291 located on the support base plate 292 and connected to the adsorption plate 1022, and two of the support side plates 291 are arranged at intervals, and the two support side plates 291 and the support base plate 292 jointly form the avoidance groove 293, and the positioning plate 1024 is located between the two support side plates 291.

[0043] Optionally, the supporting bottom plate 292 and the two supporting side plates 291 may be integrally formed by a sheet metal process, thereby reducing processing costs.

[0044] It is understandable that when the first sheet is pre-laminated, the position of the first sheet can be detected by the visual shooting mechanism so that the first sheet is in a predetermined position. When the second sheet is pre-laminated, the position of the second sheet can be detected by the visual shooting mechanism so that the second sheet is in a predetermined position.

The positioning mechanism 1013 is used to position the first material sheet for the transfer structure 103 to pick it up.

[0046] See also Figures 4 to 5Optionally, the alignment mechanism 1013 is used to correct the position of the first sheet so that the first sheet is pre-bonded to the second sheet at a predetermined position. The positioning mechanism includes a longitudinal positioning component and a transverse positioning component, the longitudinal driving component drives the two longitudinal clamping members to move toward each other, and at the same time the transverse driving component drives the two transverse clamping members to move toward each other, so that the first sheet is clamped by the two longitudinal clamping members along the first direction, and the first sheet is clamped by the two transverse clamping members along the second direction, so as to realize the positioning of the first sheet. The material transfer structure 103 moves the positioned first sheet to the top of the second sheet for subsequent pre-bonding.

[0047] See also Figures 4 to 5 Optionally, the carrier 1011 moves back and forth to continuously transport the first sheet to the positioning mechanism.

[0049] Optionally, the first sheet can be flipped at a certain angle by the flipping mechanism 1012 and released onto the alignment mechanism 1013. In this embodiment, the angle is 180 degrees. In other embodiments, the angle can be selected according to actual conditions and is not limited here.
