Description

Technical Field

[0001] This utility model relates to the field of sticker application technology, and in particular to an automatic sticker bending and pressing device. Background Technology

[0002] In the manufacturing process of backlight modules, to ensure their optical performance and structural stability, it is often necessary to fix stickers such as diffusion paper and reflective paper. For some special backlight module products, the edges of the stickers need to be bent and then glued to the side of the backlight module for a firm bond. Currently, this operation is mostly done manually. In manual operation, the edges of the stickers are bent manually, and then pressed down to adhere the bent edges to the side of the backlight module using tape. This manual method has many drawbacks.

[0003] On the one hand, the precision and consistency of manual operation are difficult to guarantee. Due to differences in the operating techniques, strength, and skill levels of different workers, it is difficult to ensure that the creases and pressure of the stickers on each backlight module are exactly the same. This can lead to some products having stickers with inaccurate bending angles, failing to adhere tightly to the sides of the backlight module, or insufficient pressure, resulting in weak adhesion between the stickers and the sides of the backlight module. This can easily lead to problems such as sticker displacement during subsequent use, seriously affecting product quality and stability.

[0004] On the other hand, manual operation is inefficient. Stickers typically have multiple areas requiring bending and pressing, and the entire process is quite cumbersome, requiring workers to complete multiple steps sequentially, each requiring careful operation. This results in a longer processing time for each product, increasing production costs. Under large-scale production demands, the efficiency of manual operation is far from meeting the company's capacity requirements, severely restricting the quality and efficiency of backlight module production. Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content

[0035] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0036] See Figures 1 to 7 This utility model provides an automatic sticker bending and pressing device, including: a worktable 1, a bending mechanism 2 and a pressing mechanism 3.

[0037] The workbench 1 is used to place the product 10 to be processed (specifically referring to the backlight module in this embodiment) and can position the product 10 to ensure the accuracy of subsequent sticker application (specifically referring to the diffusion paper, reflective paper, etc. on the backlight module in this embodiment).

[0038] The bending mechanism 2 includes a lifting block 21 that can move up and down, and a bending block 22 that is mounted on the lifting block 21 and can move horizontally relative to the lifting block 21. The bending block 22 is used to bend the sticker edge on the product 10 to the side of the product 10 during the process of descending with the lifting block 21.

[0039] The pressing mechanism 3 includes a pressing drive device 31 and a pressing block 32 connected to the pressing drive device 31. The pressing drive device 31 is used to drive the pressing block 32 to push the bending block 22 to move horizontally so as to press the bent sticker edge onto the side of the product 10.

[0040] This invention enables rapid positioning of the product 10 to be processed on the workbench 1. With the cooperation of the lifting block 21 and bending block 22 of the bending mechanism 2, the sticker edge can be bent to the side of the product 10 quickly and accurately. Subsequently, the pressing drive device 31 of the pressing mechanism 3 drives the pressing block 32 to push the bending block 22 to move horizontally to press the bent sticker edge onto the side of the product 10. The whole process is smooth and efficient, realizing the automation or semi-automation of sticker bending and pressing operations, ensuring the consistency and accuracy of sticker bending and pressing operations, greatly shortening the processing time of a single product 10, significantly improving production efficiency, and meeting the needs of large-scale production.

[0041] See Figure 1 The workbench 1 is provided with a positioning stage 11, which is provided with a positioning groove 111 and a reference mechanism distributed around the positioning groove 111. The reference mechanism is used to position the product 10 placed in the positioning groove 111.

[0042] like Figure 2 As shown, the reference mechanism includes two first reference modules 12, which are arranged opposite each other on the left and right sides of the positioning groove 111. Specifically, each of the two first reference modules 12 includes a first reference block 121 and a first detection element 122. The first reference block 121 is slidably mounted on the positioning stage 11 via a linear guide rail, and the positioning stage 11 is provided with stop pins 123 at both ends of the sliding stroke of the first reference block 121. The first detection element 122 is arranged on one side of the first reference block 121. The side of the first reference block 121 facing the product 10 is designated as the first reference surface. After the product 10 is placed in the positioning groove 111, the two first reference blocks 121 are pushed to slide towards the product 10 until the two first reference blocks 121 stop on their respective stop pins 123. At this time, the first reference surfaces of the two first reference blocks 121 are respectively attached to the left and right sides of the product 10, and the first reference blocks 121 can just be detected by the first detection element 122, indicating that the product 10 has been positioned in the left and right directions.

[0043] In addition, the reference mechanism also includes, but is not limited to, two second reference modules 13, which are arranged on the side of the positioning groove 111 opposite to the pressure block 32, so as to Figure 1 The orientation shown is for reference, that is, both second reference modules 13 are arranged on the front side of the positioning groove 111. Specifically, both second reference modules 13 include a second reference block 131 and a second detection element 132. The second reference block 131 is rotatably mounted on the positioning stage 11 via a support, and the end of the second reference block 131 away from the support is provided with a tooth 1311; the second detection element 132 is arranged on one side of the second reference block 131.

[0044] The positioning stage 11 is also provided with a stop bar 14, which is located on the front side of the positioning groove 111. When the product 10 is placed in the positioning groove 111, the front side of the product is placed against the stop bar 14, and the second reference block 131 is flipped so that the teeth 1311 of the second reference block 131 are inserted into the groove of the product 10. At this time, the second reference block 131 can be detected by the second detection element 132, indicating that the product 10 has been positioned in the front-back direction.

[0045] This utility model adopts the aforementioned reference mechanism. In the left-right direction, positioning is achieved by two first reference modules 12 arranged opposite to each other on the left and right sides of the positioning groove 111. In the front-back direction, positioning is achieved by two second reference modules 13 arranged on the front side of the positioning groove 111 and the stop bar 14 working together. This achieves high-precision, all-round positioning of the product and ensures the accuracy of the sticker application position. At the same time, auxiliary detection is performed by the first detection element 122 and the second detection element 132, which facilitates the operator or automated system to quickly confirm the positioning status.

[0046] For example, both the first detection element 122 and the second detection element 132 can be microswitches.

[0047] See Figure 1 and Figure 4 The bending mechanism 2 also includes a lifting drive device 23, which is fixedly mounted on the workbench 1 via a support plate 24. The lifting block 21 is mounted on the lifting drive device 23 and slidably connected to the support plate 24 via two linear guide rails. The lifting drive device 23 is used to drive the lifting block 21 and the bending block 22 to perform lifting and lowering movements, so as to realize the automated operation of sticker bending and pressing.

[0048] See Figures 3 to 5 The bending block 22 is mounted on the rear side of the lifting block 21 by several equal-height screws 25, which limit the horizontal movement range of the bending block 22 relative to the lifting block 21. Several elastic elements 26 are arranged between the bending block 22 and the lifting block 21. In this embodiment, the elastic elements 26 are specifically springs. Several guide shafts are also fixed on the bending block 22. The guide shafts are slidably engaged with the lifting block 21. Several springs are correspondingly fitted on the guide shafts, and the two ends of the springs elastically abut against the lifting block 21 and the bending block 22, so as to always apply a rearward elastic force to the bending block 22.

[0049] In addition, several linear bearings 27 are provided between the bending block 22 and the lifting block 21 to improve the stability of the horizontal movement of the bending block 22.

[0050] It is worth mentioning that the bottom of the lifting block 21 is provided with a pressure strip 28 for pressing the product 10. During the process of the lifting drive device 23 driving the lifting block 21 and the bending block 22 to descend, the bending block 22 is used to bend the sticker edge on the product 10 to the side of the product 10 until it is in place. At this time, the pressure strip 28 will press the sticker on the top surface of the product 10 tightly to prevent the sticker from shifting or other defects.

[0051] The pressure strip 28 can be made of a soft rubber material, such as silicone, to prevent damage to product 10.

[0052] See Figure 1 and Figure 6 The pressing mechanism 3 also includes a base 33, which is mounted on the worktable 1. The pressing drive device 31 is mounted on the base 33 and fixedly connected to the pressing block 32. The pressing block 32 is slidably connected to the base 33 via two linear guide rails to improve the stability of the horizontal movement of the pressing block 32. The pressing drive device 31 of the pressing mechanism 3 can provide stable and appropriate pressure, ensuring that the bent sticker edge is firmly pressed onto the side of the product 10, effectively avoiding product quality problems caused by differences in manual operation, and greatly improving the stability and reliability of product quality.

[0053] The bending block 22 and the pressing block 32 are each provided with a plurality of pressing teeth 321 at intervals. The plurality of pressing teeth 321 are adapted to the plurality of sticker edges to be bent on one side of the product 10, and can simultaneously perform bending and pressing operations on the plurality of sticker edges to be bent on one side of the product 10, which can further improve efficiency.

[0054] In addition, the automatic sticker bending and pressing device of this utility model also includes a pressure relief valve 4. Both the pressing drive device 31 and the lifting drive device 23 are cylinders, and the pressure relief valve 4 is connected to the air circuits of the pressing drive device 31 and the lifting drive device 23. When the air circuit pressure connected to the pressing drive device 31 and the lifting drive device 23 is higher than the set upper limit value, the pressure relief valve 4 can automatically relieve the pressure in the air circuit to ensure pressure stability. When the air circuit pressure connected to the pressing drive device 31 and the lifting drive device 23 is lower than the set lower limit value, the system issues an alarm.

[0055] Therefore, this utility model enables rapid positioning of the product 10 to be processed by the workbench 1. With the cooperation of the lifting block 21 and bending block 22 of the bending mechanism 2, the sticker edge can be bent to the side of the product 10 quickly and accurately. Then, the pressing drive device 31 of the pressing mechanism 3 drives the pressing block 32 to push the bending block 22 to move horizontally to press the bent sticker edge onto the side of the product 10. The whole process is smooth and efficient, realizing the automation of sticker bending and pressing operations, ensuring the consistency and accuracy of sticker bending and pressing operations, greatly shortening the processing time of a single product 10, significantly improving production efficiency, and meeting the needs of large-scale production.

[0056] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
