[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

The directional terms used are for the purpose of explaining and understanding this utility model, and are not intended to limit this utility model.

[0032] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, a connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components.

[0034] In existing technologies, the scraper block is generally used only on one side for scraping adhesive. During scraping, the scraper block is driven by a corresponding drive mechanism to perform multiple actions such as movement or rotation. This results in rapid wear of the scraper and high costs. Furthermore, existing scraping equipment also suffers from poor scraping effect, with adhesive residue easily accumulating on the product surface, leading to frequent downtime for cleaning and impacting work efficiency.

[0035] The semi-finished products after dispensing adhesive need to be protected with a film. When assembling and manufacturing them, the film needs to be removed, so the process of applying easy-tear adhesive to the film is also involved.

[0036] The following is a preferred embodiment of a glue scraping device for display screen products provided by this utility model, which can solve the above-mentioned technical problems.

[0037] Please refer to the reference. Figure 2 and Figure 3 ,in Figure 2 This is a schematic diagram of the adhesive scraping device for display screen products according to the present invention. Figure 3 This is a schematic diagram of the connecting components and the scraping block of the adhesive scraping device for display screen products according to this utility model.

[0038] In the diagram, units with similar structures are represented by the same labels.

[0039] This embodiment provides a scraping device 13 for display screen products, which includes a scraping platform 131 and a scraper mechanism movably disposed above the scraping platform 131.

[0040] The scraper mechanism includes a scraper moving frame 132, a lifting drive mechanism, a connecting assembly 134, and a scraper block 135.

[0041] The lifting drive mechanism is located at the top of the movable frame 132. The connecting component 134 is connected to the output end of the lifting drive mechanism. The scraper block 135 is located at the bottom of the connecting component 134. The scraper block 135 has scraping bevels 1351 on both sides for scraping adhesive onto the display screen product. The scraping bevels 1351 on both sides of the scraper block 135 are connected in a V-shape. The scraping bevels 1351 on both sides can perform scraping operations on different parts of the display screen product, allowing for more efficient use of the scraper block 135, reducing wear and tear, and lowering costs.

[0042] Please refer to Figure 3 In this embodiment, a through groove 1352 is provided on the squeegee block 135. The through groove 1352 extends along a plane perpendicular to the squeegee inclined surface 1351 and passes through the squeegee inclined surfaces 1351 on both sides. The through groove 1352 gives each squeegee inclined surface 1351 two edges for squeegeeing, resulting in better squeegeeing effect and longer service life of the squeegee block 135. At the same time, the through groove 1352 can store waste glue after squeegeeing, so that glue residue is less likely to accumulate on the surface of the display product, and the squeegeeing effect is better.

[0043] Please refer to Figure 2 The scraper mechanism also includes a waste glue collection tank 136, a protective cover 137, and an air blowing mechanism 138. The waste glue collection tank 136 is located below the scraping platform 131. The protective cover 137 has a U-shaped structure and encloses the space between the scraping block 135 and the waste glue collection tank 136. Multiple air blowing mechanisms 138 are arranged inside the protective cover 137. The air blowing direction of the air blowing mechanism 138 is towards the through groove 1352 of the scraping block 135 and the scraping platform 131, so as to blow the waste glue scraped off by the through groove 1352 and the scraping platform 131 into the waste glue collection tank 136.

[0044] Please refer to Figure 3In this embodiment, the connecting component 134 includes an upper connecting block 1341, a lower connecting block, and a pressure sensor 1344. The upper connecting block 1341 is connected to the output end of the lifting drive mechanism, the pressure sensor 1344 is connected between the upper connecting block 1341 and the lower connecting block, and the scraping block 135 is disposed at the bottom of the lower connecting block. The pressure sensor 1344 can stably control the scraping force.

[0045] Furthermore, the lower connecting block includes a fixed block 1342 and a movable block 1343. The fixed block 1342 is fixedly connected to the pressure sensor 1344, and the movable block 1343 is rotatably connected to the bottom of the fixed block 1342. The rotation axis of the movable block 1343 is parallel to the lifting direction of the scraper block 135, and the scraper block 135 is connected to the bottom of the movable block 1343.

[0046] Please refer to Figure 3 More specifically, the connecting assembly 134 also includes an adjusting seat 1345, an adjusting block 1346, and an adjusting screw 1347. The adjusting block 1346 is fixedly mounted on one side of the movable block 1343, and the adjusting seat 1345 is fixedly mounted on one side of the fixed block 1342. The adjusting seat 1345 has lugs at both ends, and the adjusting block 1346 is located between the two lugs. The adjusting screw 1347 passes through and is threaded into the lugs. The adjusting screws 1347 on the two lugs contact the two sides of the adjusting block 1346 respectively. By rotating and adjusting the tightening depth of the two adjusting screws 1347, the adjusting block 1346 is driven to change position, thereby rotating and adjusting the orientation of the movable block 1343, and thus changing the adhesive scraping orientation of the scraper block 135.

[0047] In addition, the bottom of the movable block 1343 is provided with a connecting groove 13431 for connecting the scraper block 135. The fastening screw passes through the movable block 1343 and is threadedly connected to the scraper block 135 in the connecting groove 13431, thereby fixing the scraper block 135 to the movable block 1343, making the scraper block 135 very convenient to install and remove and the connection very stable.

[0048] In this embodiment, the fastening screw is parallel to the adjusting screw 1347. The side of the movable block 1343 opposite to the fastening screw is penetrated by the connecting groove 13431. The inner wall surface of the connecting groove 13431 near the fastening screw is provided with expansion grooves 13432. The expansion grooves 13432 are used to avoid the edge of the scraper block 135, so as to ensure the accuracy and stability of the connection between the scraper block 135 and the movable block 1343.

[0049] Please refer to Figure 2In this embodiment, the lifting drive mechanism includes a motor screw assembly 1331, a scraper cylinder 1332, and a connecting frame 1333. The scraper cylinder 1332 is connected to the output end of the motor screw assembly 1331 via the connecting frame 1333, and the connecting assembly 134 is connected to the output end of the scraper cylinder 1332. The motor screw assembly 1331 can quickly drive the scraper block 135 to move up and down, and the scraper cylinder 1332 can drive the scraper block 135 to contact the display screen product with a set pressure for scraping adhesive.

[0050] In this embodiment, the adhesive scraping device 13 includes two adhesive scraping platforms 131, both of which are connected to the output end of the Y-axis moving module 139. The adhesive scraping moving frame 132 is connected to the output end of the X-axis moving module 13A. By driving the adhesive scraping platform 131 to move in the Y-axis, and coordinating with the X-axis movement of the adhesive scraping block 135, the adhesive scraping block 135 can scrape adhesive onto both sides of the display screen product on the two adhesive scraping platforms 131, resulting in high efficiency and low cost.

[0051] Please refer to Figure 1 The adhesive scraper device 13 of this embodiment can be applied to an adhesive scraper film applicator. The adhesive scraper film applicator also includes a feeding device 11, a conveying device 12, a film skiving device 14, and an applicator 15.

[0052] The feeding device 11 includes a movable feeding platform that can receive the display screen products from the front-end equipment and transport them to the scraping device 13, which performs scraping operation on the display screen products on the scraping platform 131.

[0053] The conveying device 12 is docked at the end of the feeding device 11 in the conveying direction. The conveying device 12 includes multiple robotic arms 121 for gripping and conveying display screen products. A scraping device 13, a film skiving device 14, and an attachment device 15 are sequentially arranged on one side of the conveying device 12. The robotic arms 121 can grip and convey the display screen products from the feeding platform to the scraping platform 131, from the scraping platform 131 to the film skiving platform 141, from the film skiving platform 141 to the attachment platform 151, and then grip and output the display screen products from the attachment platform 151 to the downstream equipment.

[0054] It should be noted that the adhesive scraping platform 131, the film skiving platform 141, and the attachment platform 151 are all equipped with suction holes for holding the display screen product. Additionally, multiple sensors can be installed throughout the entire workflow to monitor the transport position of the display screen product.

[0055] The film-removing device 14 includes a film-removing platform 141, film-removing tape 142, a film-removing roller mechanism 143, and a tape control module 144. The film-removing platform 141 can rotate about a pivot perpendicular to the film-removing platform 141. The film-removing roller mechanism 143 is movably disposed above the film-removing platform 141. The film-removing tape 142 is wound around the tape control module 144 and the film-removing roller mechanism 143. The film-removing roller mechanism 143 moves to allow the film-removing tape 142 to adhere to a corner of the film layer of the display screen product on the film-removing platform 141, and then reattach the adhered corner to the display screen product, causing a loosening effect on a corner of the film layer. Subsequently, an easy-tear sticker is attached to the loosened corner of the film layer, allowing the film layer to be easily peeled off using the easy-tear sticker.

[0056] The application device 15 includes an application platform 151, an easy-tear sticker feeding mechanism 152, and an application robot 153 movably disposed above the application platform 151. The application robot 153 applies the easy-tear sticker provided by the easy-tear sticker feeding mechanism 152 to a corner of the film layer of the display product.

[0057] The working principle of this utility model is as follows: The handling robot 121 can grab and transport the display screen product from the feeding platform to the glue scraping platform 131, grab and transport the display screen product from the glue scraping platform 131 to the film skidding platform 141, grab and transport the display screen product from the film skidding platform 141 to the bonding platform 151, and grab and output the display screen product from the bonding platform 151 to the downstream equipment.

[0058] When the display product needs to be scraped with glue on the glue scraping platform 131, the Y-axis moving module 139 drives the glue scraping platform 131 to move in the Y direction closer to the scraper mechanism. Then, the lifting drive mechanism drives the glue scraper block 135 to descend, so that the glue scraper block 135 contacts the side of the display product. Then, the Y-axis moving module 139 drives the glue scraping platform 131 to move in the Y direction away from the scraper mechanism. In this way, the glue scraper block 135 can complete the glue scraping operation on the side of the display product.

[0059] Next, the X-axis moving module 13A drives the scraper moving frame 132 to move in the X direction, so that the scraper slope 1351 is opposite to the other side of the display product or the side of the display product on another scraper platform 131. Afterwards, the scraper platform 131 moves in conjunction with the lifting drive mechanism to drive the scraper block 135 to descend and complete the scraping operation on the display product again.

[0060] This completes the working process of the adhesive scraping device for display screen products according to the preferred embodiment of this invention.

[0061] The glue scraping device of this preferred embodiment has glue scraping bevels on both sides, so that glue scraping operations can be performed on different parts of the display screen product. The glue scraping block is more fully utilized, less prone to wear, and has low cost.

[0062] In addition, the scraper block has a through groove, which gives each side of the scraper bevel two edges for scraping glue. This makes the scraper block more effective and longer-lasting. At the same time, the through groove can store the scraped glue, so that glue residue is less likely to accumulate on the product surface, resulting in better scraping performance.

[0063] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
