Description

Technical Field

[0001] This application relates to the field of dispensing equipment technology, and in particular to a dispensing machine for screwless adhesive bonding of light strips. Background Technology

[0002] Touchscreens, as key devices for human-computer interaction, have extremely wide and ever-expanding applications in today's society. From flat touchscreens in consumer electronics, providing users with a convenient and smooth operating experience, to electronic touchscreens in the education industry, enabling interactive teaching and information display, and to touchscreens in business scenarios, such as conference rooms, for note-taking, improving the efficiency of meeting discussions and recording, they play an important role in all aspects of life, work, and study. With the continuous advancement of technology, touchscreen technology is also constantly iterating and upgrading. The market has placed higher demands on the performance, reliability, and manufacturing cost of touchscreens, making the optimization and improvement of their internal structure an important research direction in the industry, aiming to further improve the overall quality and user experience of touchscreens. In the internal structure of touchscreens, in order to fix the LED strip to the back panel of the touchscreen, the usual practice is to make holes in the LED strip and then fix it to the back panel with screws. While the LED strip fits well with the back panel of the touchscreen at the screw fixing section, the part away from the screw may separate from the back panel, forming a gap. The gapped part of the LED strip is prone to poor heat dissipation, affecting the lifespan of the LED strip and the performance of the touchscreen. Therefore, some manufacturers now use adhesive to directly bond the LED strip to the touch screen back panel. The operator needs to hold an adhesive applicator and apply adhesive to a specific location on the touch screen back panel to form an adhesive line. Then, the LED strip is placed on the adhesive line and gently pressed together. After the adhesive cools and cures, the LED strip and the touch screen back panel are firmly bonded, which solves the problem of poor heat dissipation caused by using screws for fixing.

[0003] However, the above-mentioned dispensing method still has obvious defects in practical applications. On the one hand, relying on manual dispensing is inefficient and cannot meet the needs of large-scale production. On the other hand, relying on manual dispensing makes the glue line easy to bend and the amount of glue dispensing is difficult to control. As a result, when installing light strips, the glue is not straight and it is easy for the glue to overflow from the edge of the light strip. This not only affects the appearance, but also requires additional removal of the overflowing glue, especially in the production of some high-end flat touch screens, which have high processing requirements. This increases the production process and cost. Utility Model Content

[0004] In order to meet the needs of large-scale production, improve dispensing efficiency and accuracy, effectively control the amount of adhesive dispensed, and avoid the phenomenon of adhesive line bending, this application provides a dispensing machine for screwless adhesive bonding of light strips.

[0005] This application provides a dispensing machine for screwless adhesive bonding of LED strips, including a frame and an LED strip support mechanism and a translational dispensing mechanism disposed on the frame. LED strips are arranged parallel to each other and spaced apart on the support mechanism. The translational dispensing mechanism includes a dispensing component and a linear drive mechanism. The linear drive mechanism is disposed on the frame, and the dispensing component is positioned directly above the LED strip support mechanism. The dispensing component has a plurality of dispensing needles arranged facing the LED strips, each corresponding to a specific LED strip. The linear drive mechanism drives the dispensing component to reciprocate along the length of the LED strip. By adopting the above technical solution, during the dispensing operation, the dispensing needles can accurately dispense adhesive onto the LED strip, and then the LED strip with adhesive is bonded to the touch screen back panel. Because the dispensing component is driven by the linear drive mechanism to move linearly, the problem of adhesive line bending is avoided, making the adhesive line straighter. Simultaneously, the linear drive makes the dispensing process more stable, and the amount of adhesive dispensed can be better controlled, reducing the situation of adhesive overflowing from the edges of the LED strip, avoiding the additional process of removing overflowing adhesive, and reducing production processes and costs. Moreover, multiple dispensing needles can simultaneously dispense adhesive onto multiple LED strips, greatly improving dispensing efficiency and meeting the needs of large-scale production. In existing methods, the LED strips need to be aligned with the adhesive lines on the back panel of the touch screen for bonding, which inevitably leads to LED strip deviation and adhesive overflow. However, this technical solution avoids the problem of inaccurate bonding in existing methods by directly applying adhesive to the LED strip.

[0006] Preferably, the light strip support mechanism includes a support platform and support rods disposed on the support platform. The support platform is horizontally disposed on the top of the frame, and the support rods are parallel and spaced apart along the length of the light strip. The light strips are spaced apart on the support rods along the width of the light strip. By adopting the above technical solution, the support platform is horizontally disposed on the top of the frame, providing a stable support foundation for the support rods and light strips. The support rods are parallel and spaced apart along the length of the light strip, allowing the light strips to be placed spaced apart on the support rods along the width of the light strip. This arrangement allows for simultaneous dispensing of multiple light strips, greatly improving dispensing efficiency and meeting the needs of large-scale production. Moreover, the support rods provide good support for the light strips, ensuring that the light strips remain stable during dispensing, preventing light strip wobbling, and helping to form a straight and uniform glue line. Preferably, the light strip support mechanism further includes a mounting rod and fasteners. Both ends of the support rod are suspended from the support platform via the mounting rod. The mounting rod has a first mounting groove along the length of the light strip. Both ends of the support rod are movably installed in the first mounting groove via the fasteners to adjust the installation position of the support rod. By adopting the above technical solution, the two ends of the support rod of the light strip support mechanism are suspended from the support platform via the mounting rod, and the mounting rod has a first mounting groove along the length of the light strip. Both ends of the support rod are movably installed in the first mounting groove via fasteners. Because the support rod can move within the first mounting groove, the operator can flexibly adjust the installation position of the support rod according to the size specifications of different light strips and installation requirements. In this way, the dispensing machine can adapt to various sizes of light strips, improving the versatility and applicability of the dispensing machine, avoiding the hassle of changing different support mechanisms for different sizes of light strips, reducing production costs, and better meeting diverse production needs. Preferably, each of the supporting rods is provided with a plurality of limiting grooves at intervals, the width of which is greater than the width of the light strip. By adopting the above technical solution, the supporting rods are provided with a plurality of limiting grooves at intervals, the width of which is greater than the width of the light strip, which can limit the light strip. When placing the light strip, the light strip can be accurately placed in the limiting groove, preventing the light strip from sliding or deviating at will. Since the limiting groove constrains the light strip, the position of the light strip remains stable during the dispensing process, thereby ensuring the accuracy and consistency of dispensing. After the accuracy and consistency of dispensing are improved, the formed glue line is more regular, avoiding the problem of glue line bending caused by the unstable position of the light strip. Preferably, a flexible covering sheet is provided in the limiting groove. By adopting the above technical solution, the limiting groove is used to place the light strip. When the light strip is placed in the limiting groove, the flexible covering sheet provided in the limiting groove is soft and can fit tightly with the light strip. This bonding prevents the light strip from slipping on the limiting groove, reduces hard impacts and friction on the light strip during placement and adhesive application, thereby preventing the light strip from shaking, scratching or damaging the surface, and ensuring the stability and appearance integrity of the light strip.Preferably, the dispensing assembly further includes an adhesive delivery assembly and a support. The support is disposed above the supporting platform. The linear drive mechanism drives the support to reciprocate along the length of the light strip. The dispensing needles are arranged on the support. The adhesive delivery assembly includes an adhesive reservoir and several dispensing tubes. Each dispensing tube corresponds to a dispensing needle, with one end connected to the adhesive reservoir and the other end connected to the corresponding dispensing needle. By adopting the above technical solution, during the process of the linear drive mechanism driving the dispensing needles to move along the length of the light strip, the dispensing needles can continuously and uniformly dispense adhesive onto the light strip. This avoids the instability of manual operation, ensures a straighter adhesive line, and allows for precise control of the dispensing amount. It effectively prevents adhesive from overflowing from the edge of the light strip, reduces the need for additional adhesive removal, lowers production steps and costs, and improves dispensing efficiency to meet the needs of large-scale production. Preferably, the dispensing assembly further includes a lifting structure, which comprises a guide rail and a sliding plate. The guide rail is located in the middle of the bracket and is vertically suspended above the support platform. The sliding plate is horizontally positioned on the guide rail and slides along it. The dispensing needles are arranged on the sliding plate. By adopting the above technical solution, during dispensing operations, the sliding plate can slide along the guide rail, driving the dispensing needles to achieve lifting and lowering movements. Before dispensing, the dispensing needles can be raised to facilitate the placement of the light strip onto the support mechanism. After the light strip is placed, the dispensing needles are lowered to be close to the light strip, enabling precise dispensing operations on the light strip, improving the accuracy of the dispensing position, and avoiding dispensing deviation. Simultaneously, during the dispensing process, if the dispensing height needs to be adjusted, the height of the dispensing needles can be adjusted at any time through the lifting structure to adapt to light strips with different height requirements or different dispensing processes. This allows the dispensing machine to adapt to dispensing operations on various types of light strips, improving the versatility and applicability of the dispensing machine. Preferably, a second mounting groove is horizontally provided on the skateboard, and each dispensing needle can be movably installed in the second mounting groove. By adopting the above technical solution, a second mounting groove is horizontally provided on the skateboard, and each dispensing needle can be movably installed in the second mounting groove. In this way, the operator can flexibly adjust the position of the dispensing needle in the second mounting groove according to the width, spacing, and other specifications of different light strips, so that the dispensing needle can accurately correspond to the dispensing position of the light strip. Preferably, it also includes a positioning component, which includes a positioning plate. The positioning plate is disposed on the support platform and parallel to the support rod. The positioning plate is provided with a positioning groove corresponding to the dispensing needle. The positioning groove is coaxially arranged with the corresponding limiting groove. When the dispensing needle is driven to move downward, the dispensing port of the dispensing needle extends into the corresponding positioning groove. Then, when the dispensing needle is driven to move horizontally, the dispensing port of the dispensing needle moves along the top of the light strip. By adopting the above technical solution, the positioning plate is set on the support platform and parallel to the support rod. The positioning plate is provided with a positioning groove corresponding to the dispensing needle. The positioning groove and the corresponding limiting groove are coaxially arranged.When the dispensing needle moves downwards, its outlet accurately enters the corresponding positioning groove, providing precise initial positioning for subsequent translational dispensing operations. Since the positioning groove and the limiting groove are coaxial, and the limiting groove is used to place the LED strip, the dispensing needle's outlet can move stably and accurately along the top of the LED strip during subsequent translation. This avoids the problem of adhesive line bending and ensures the straightness of the adhesive line. Preferably, the bracket has a downward-facing "U"-shaped structure. By adopting the above technical solution, designing the bracket as a downward-facing "U"-shaped structure provides ample space for the LED strip support mechanism below the dispensing assembly and the LED strip itself. The "U"-shaped structure has good stability and support, ensuring the smoothness of the dispensing needle during movement, making the dispensing process more precise, and helping to improve dispensing quality and efficiency.

[0007] In summary, this application includes at least one of the following beneficial technical effects: 1. The dispensing machine includes a frame, a light strip support mechanism, and a translational dispensing mechanism. It bonds the light strip to the touch screen back panel by dispensing glue onto the light strip, avoiding the low efficiency of manual operation, improving dispensing efficiency and accuracy, and meeting the needs of large-scale production. 2. A linear drive mechanism is mounted on the frame and drives the dispensing assembly to move back and forth along the length of the light strip. The dispensing assembly is equipped with several dispensing needles that face the light strip and correspond one-to-one with the light strip. Under the drive of the linear drive mechanism, the dispensing needles can form a straight glue line, avoiding bending of the glue line. 3. The dispensing assembly includes an adhesive delivery assembly and a bracket, etc. The adhesive delivery assembly supplies adhesive to the dispensing needle through an adhesive storage tank and an adhesive delivery tube. This setup can better control the amount of adhesive dispensed, prevent adhesive from overflowing the edge of the light strip, and reduce the process and cost of removing overflowing adhesive.

[0010] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0011] This application provides an embodiment of a dispensing machine for screwless adhesive bonding of LED strips, referencing... Figure 1 and Figure 2 The system includes a frame 1, a light strip support mechanism 2, and a translational dispensing mechanism 3. Both the light strip support mechanism 2 and the translational dispensing mechanism 3 are mounted on the frame 1. Light strips 5 are arranged parallel to and spaced apart on the support mechanism 2. The translational dispensing mechanism 3 can reciprocate above the light strips 5 to achieve automatic dispensing of the light strips 5, resulting in efficient and precise dispensing. In this embodiment, the support mechanism 2 can hold four light strips 5 at a time, and the translational dispensing mechanism 3 can perform simultaneous dispensing operations on four light strips 5 in a single operation.

[0012] Specifically, the light strip support mechanism 2 in this embodiment includes a support platform 21, a support rod 22, a mounting rod 23, and fasteners 24. The plate-shaped support platform 21 is horizontally positioned on top of the frame 1. Both the support platform 21 and the frame 1 are made of metal, such as aluminum alloy. Aluminum alloy has advantages such as light weight, high strength, and corrosion resistance, and can provide a stable support foundation for the entire light strip support mechanism 2.

[0013] In this embodiment, there are two mounting rods 23, which are arranged parallel to each other on the support platform 21 and parallel to the light strip 5. There are four support rods 22, which are spaced apart at the top of the mounting rods 23 along the length of the mounting rods 23 and are parallel to each other. The light strip 5 is spaced apart on the support rods 22 along the length of the support rods 22. Each support rod 22 is located between two mounting rods 23, and both ends of each support rod 22 are detachably connected to the two mounting rods 23 by fasteners 24, so that the middle of each support rod 22 is suspended in the support platform 21. In particular, the two mounting rods 23 are provided with a first mounting groove 231 along the length of the light strip 5, and both ends of the support rod 22 are movably installed in the first mounting groove 231 by fasteners 24. In this way, when it is necessary to adapt to different specifications of light strip 5, such as when the length of light strip 5 becomes longer, the fastener 24 can be loosened, the support rod 22 can be moved outward along the first mounting groove 231 to increase the distance between the support rods 22, and then the fastener 24 can be tightened to fix the position of the support rod 22; conversely, when the length of light strip 5 becomes shorter, the distance between the support rods 22 can be reduced.

[0014] Each support rod 22 is provided with four spaced limiting grooves 221. The width of the limiting grooves 221 is greater than the width of the light strip 5, and the size of the limiting grooves 221 is designed to fit one light strip 5. The limiting grooves 221 can limit the movement of the light strip 5, preventing it from moving laterally or longitudinally during the dispensing process, and ensuring the stability of the light strip 5. A flexible covering sheet 222 is provided inside the limiting grooves 221. The flexible covering sheet 222 can be made of rubber or silicone. Both rubber and silicone have good flexibility and elasticity, which can prevent the light strip 5 from being damaged by direct contact with the limiting grooves 221. At the same time, it can also increase the friction between the light strip 5 and the limiting grooves 221, further improving the stability of the light strip 5.

[0015] Reference Figure 2 and Figure 3Specifically, the translational dispensing mechanism 3 in this embodiment includes a dispensing assembly 31 and a linear drive mechanism 32. The linear drive mechanism 32 is disposed on the frame 1, and the dispensing assembly 31 is disposed directly above the light strip support mechanism 2. The dispensing assembly 31 includes dispensing needles 311, an adhesive delivery assembly 312, a bracket 313, and a lifting structure 314. In this embodiment, there are four dispensing needles 311. The bracket 313 is disposed above the support platform 21, and the linear drive mechanism 32 drives the bracket 313 to reciprocate along the length of the light strip 5. The bracket 313 has a downward-facing "U"-shaped structure. Both ends of the bracket 313 are connected to the output ends of the linear drive mechanism 32, and the middle of the bracket 313 is suspended above the support platform 21. This structure makes the bracket 313 more stable because the "U" shape has a large bottom support area, capable of bearing the weight of the dispensing assembly 31 and maintaining balance. It also facilitates the installation of other components, such as the glue delivery assembly 312, the dispensing needle 311, and the lifting structure 314, all of which can be easily mounted on the "U"-shaped bracket 313. The linear drive mechanism 32 in this embodiment is a conventional screw and nut transmission structure; its specific structure and working principle will not be described in detail here.

[0016] The lifting structure 314 includes a guide rail 314a and a sliding plate 314b. The guide rail 314a is located in the middle of the bracket 313 and is vertically suspended above the support platform 21. The sliding plate 314b is horizontally positioned on the guide rail 314a and slides along it. Four dispensing needles 311 are horizontally arranged on the sliding plate 314b, with all four needles aligned. A second mounting groove 314b1 is horizontally provided on the sliding plate 314b, and each dispensing needle 311 can be movably installed into the second mounting groove 314b1 using bolts or other fasteners. When different dispensing requirements need to be met, such as changes in the dispensing position of the light strip 5 or adjustments to the dispensing spacing, the connection between the dispensing needle 311 and the second mounting groove 314b1 can be loosened, the dispensing needle 311 can be moved along the second mounting groove 314b1 to a suitable position, and then the dispensing needle 311 can be fixed, thereby achieving adjustment of the dispensing position and spacing.

[0017] The glue delivery assembly 312 includes a glue storage cylinder 312a and several glue delivery tubes 312b. Each glue delivery tube 312b corresponds to a dispensing needle 311. One end of each glue delivery tube 312b is connected to the glue storage cylinder 312a, and the other end is connected to the corresponding dispensing needle 311. The glue storage cylinder 312a stores glue, and the glue is delivered to the corresponding dispensing needle 311 through the glue delivery tubes 312b. The glue storage cylinder 312a generally has a certain sealing performance to prevent glue leakage and evaporation, ensuring the quality and supply stability of the glue. In particular, each dispensing needle 311 is also equipped with an air pump and a pressure regulating valve. The air pump provides stable air pressure, and the pressure regulating valve controls the air pressure to precisely adjust the glue dispensing volume. The glue outlet of each dispensing needle 311 faces the corresponding light strip 5.

[0018] Specifically, the dispensing machine also includes a positioning component 4, which includes a positioning plate. The positioning plate is disposed on the support platform 21 and parallel to the support rod 22. The positioning plate is provided with a positioning groove 41 corresponding to the dispensing needle 311. The positioning groove 41 is coaxially arranged with the corresponding limiting groove 221. When the dispensing needle 311 is driven to move downward, the dispensing port of the dispensing needle 311 extends into the corresponding positioning groove 41. The positioning groove 41 can provide accurate positioning for the dispensing needle 311, ensuring that the dispensing port of the dispensing needle 311 can be accurately aligned with the dispensing position of the light strip 5. Then, when the dispensing needle 311 is driven to move horizontally, the dispensing port of the dispensing needle 311 moves along the top of the light strip 5. The positioning component 4 can ensure the accuracy of dispensing and prevent glue from overflowing from the edge of the light strip 5.

[0019] The implementation principle of this embodiment is as follows: The screwless adhesive dispensing machine for LED strips in this embodiment consists of a frame 1 and an LED strip support mechanism 2 and a translational dispensing mechanism 3 mounted on it. The support mechanism 2 can hold four LED strips 5 at a time, and the translational dispensing mechanism 3 can automatically dispense adhesive to them simultaneously. In the LED strip support mechanism 2, the support platform 21 is horizontally placed on the top of the frame 1, and two parallel mounting rods 23 are mounted on it and parallel to the LED strips 5. The two ends of the four support rods 22 are movably mounted in the first mounting groove 231 of the mounting rods 23 by fasteners 24, and the spacing can be adjusted according to the length of the LED strips 5. Each support rod 22 has four limiting grooves 221, and the grooves are provided with flexible rubber or silicone covering sheets 222 to stabilize the LED strips 5. In the translational dispensing mechanism 3, the linear drive mechanism 32 is located on the frame 1, and its drive mechanism, which is U-shaped and suspended in the middle, drives the dispensing assembly 31 to move. The lifting structure 314 of the dispensing assembly 31 consists of a guide rail 314a and a slide plate 314b. Four dispensing needles 311 are flush on the slide plate 314b and their positions can be adjusted through the second mounting groove 314b1. The glue storage cylinder 312a of the glue delivery assembly 312 delivers glue to the dispensing needles 311 through the glue delivery pipe 312b. Each dispensing needle 311 is equipped with an air pump and a pressure regulating valve to accurately adjust the glue dispensing volume. The positioning plate of the positioning assembly 4 is located on the support platform 21. Its positioning groove 41 is coaxial with the limiting groove 221, which can position the dispensing needles 311 and ensure accurate dispensing.

[0020] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
