Description

Technical Field

[0001] This application belongs to the technical field of dispensing equipment structure, specifically relating to a dispensing machine. Background Technology

[0002] In the photo frame manufacturing industry, as people's demands for quality of life and aesthetics continue to rise, photo frames, as an important medium for decorating and preserving photos, are experiencing increasing market demand. This also places higher demands on the quality and production efficiency of photo frames. Photo frames are typically composed of several frame strips joined together. To ensure the structural strength and stability of the frame, these strips need to be glued together using an adhesive process.

[0003] Traditional methods of dispensing adhesive for picture frames have several problems. Firstly, manual dispensing is inefficient and cannot meet the demands of large-scale production. Furthermore, the consistency of manual operation is difficult to guarantee, leading to uneven adhesive application and inaccurate dispensing positions, resulting in inconsistent frame quality and affecting the product's aesthetics and lifespan. Secondly, while some existing simple automated dispensing equipment improves efficiency to some extent, its functionality is limited. It typically only allows for simple single-axis or dual-axis movement and cannot flexibly adapt to the complex dispensing paths required for frames of different sizes and shapes. For example, for frames with special shapes (such as curved or irregular shapes), or at corners or joints of frame strips, these devices struggle to precisely control the dispensing position and amount, easily resulting in defects such as missed glue, excessive glue, or discontinuous glue lines, thus reducing the overall quality and yield rate of the frames. In addition, traditional dispensing equipment lacks effective collaborative operation capabilities when dispensing multiple frames simultaneously, failing to achieve synchronous dispensing at multiple stations, resulting in limited improvements in production efficiency.

[0004] Meanwhile, managing the various connection lines of the dispensing valve is also a significant issue during the use of dispensing machines. Dispensing valves typically require connection to multiple lines, including glue delivery pipes and air pipes. In existing dispensing machines, these connection lines are often tangled and disorganized, easily becoming entangled and pulled during valve movement. This not only affects the normal movement and operational accuracy of the dispensing valve but can also lead to pipe damage, leaks, and other problems, increasing equipment maintenance costs and downtime, and further impacting production efficiency.

[0005] Therefore, in order to improve the quality and efficiency of picture frame production, reduce production costs, and meet market demand for high-quality picture frames, it is imperative to develop a dispensing machine capable of three-axis movement, multi-station collaborative operation, and effective management of various connection lines of the dispensing valve. This dispensing machine will be able to precisely control the dispensing position and amount, adapt to the dispensing needs of picture frames with various complex shapes, improve production efficiency, and bring greater economic benefits and competitiveness to the picture frame manufacturing industry.

[0049] A dispensing machine includes a fixed platform 6, a production line 7 mounted on the fixed platform 6, a gantry frame 1 mounted on the fixed platform 6 and located above the production line 7, multiple dispensing mechanisms 2 including correspondingly connected glue storage cylinders 21, dispensing valves 22, and pneumatic drive components 23, a first drive assembly 3 for driving the dispensing valves 22 to move axially along the X-axis, a second drive assembly 4 for driving the dispensing valves 22 to move axially along the Y-axis, and a third drive assembly 5 for driving the dispensing valves 22 to move axially along the Z-axis, wherein the gantry frame... A cover 8 is installed on the frame 1. The cover 8 is used to cover the first drive assembly 3. A third fixing frame 81 is installed on the cover 8. A glue storage cylinder 21 is fixedly installed on the third fixing frame 81. The glue storage cylinder 21 is connected to the dispensing valve 22 through the second connecting pipe 210. Multiple dispensing valves 22 are installed on the third drive assembly 5 through the first fixing frame 24 and screws 25. The first drive assembly 3, the second drive assembly 4 and the third drive assembly 5 are connected by transmission. The pneumatic drive component 23 is connected to the dispensing valve 22 through the connecting and tidying component 26.

[0050] In practical applications, the inlet of assembly line 7 is connected to the production line for transporting picture frames, and the outlet of assembly line 7 is connected to the production line for subsequent processing of picture frames, ensuring the smooth operation of the entire picture frame manufacturing process. In this embodiment, the first drive component 3, the second drive component 4, and the third drive component 5 work together to enable the dispensing valve 22 of the dispensing machine in this embodiment to achieve three-axis motion, thereby meeting various production needs and accurately controlling the dispensing position and improving processing accuracy. In this embodiment, four dispensing mechanisms 2 are provided. It can be understood that the number of dispensing mechanisms 2 can be adaptively adjusted according to actual production needs, and multi-station collaborative action can be achieved. In this embodiment, the connection and sorting component 26 can sort out the connection lines of the dispensing valve 22, thereby eliminating production hazards caused by various connection lines of the dispensing valve and improving production safety. In this embodiment, the dispensing valve 22 is fixed by screws 25, and the distance between multiple dispensing valves can be easily and conveniently adjusted according to actual needs during use.

[0051] Specifically, the first drive assembly 3 includes a first drive member 31 and a first moving plate 32 that is connected to the first drive member 31 in a transmission manner. The gantry frame 1 includes a flat frame 11 and vertical frames 12 located at both ends of the flat frame 11. The first drive assembly 3 and the first moving plate 32 are mounted on the flat frame 11. The first drive assembly 3 also includes a first lead screw 33 and a first transmission member 34 that is installed corresponding to the first lead screw 33. The first lead screw 33 is installed at the output end of the first drive member 31. The first transmission member 34 is fixedly installed on the first moving plate 32. A first guide rail 13 is installed on the flat frame 11. A first slider 35 that matches the first guide rail 13 is installed on the first moving plate 32. The flat frame 11 is provided with mounting holes 111 that are intersected with the first guide rail 13. The mounting holes 111 are used for placing the second drive assembly 4.

[0052] In practical applications, when it is necessary to adjust the position of the dispensing valve 22 in the X-axis direction, the first driving component 31 is activated, driving the first lead screw 33 to control the position of the first transmission component 34, and thus control the position of the first moving plate 32. Since the first driving component 3, the second driving component 4 and the third driving component 5 are connected by transmission, the position of the dispensing valve 22 installed on the third driving component 5 in the X-axis can be adjusted.

[0053] Specifically, the second drive assembly 4 includes a second drive member 41 and a second moving plate 42 that is driveably connected to the second drive member 41. The second drive member 41 is mounted on the first moving plate 32. First fixed plates 36 extend downward from both sides of the first moving plate 32. The second drive assembly 4 also includes a second lead screw 43, a second fixed plate 44, a first transmission plate 45, and a second transmission member 46 that is installed corresponding to the second lead screw 43. The second lead screw 43 is mounted at the output end of the second drive member 41. The second transmission member 46 is fixedly mounted on the second moving plate 42. The first transmission plate 45 is connected to the second moving plate 42. The second fixed plate 44 is fixedly connected to the first fixed plate 36. A second guide rail 47 is mounted on the second fixed plate 44. A second slider 48 that matches the second guide rail 47 is mounted on the first transmission plate 45.

[0054] In practical applications, the second driving component 41 is mounted on the first moving plate 32, so that the second driving component 4 can change according to the position of the first driving component 3. When it is necessary to adjust the position of the dispensing valve 22 in the Y-axis direction, the second driving component 41 is activated, driving the second lead screw 43 to control the position of the second transmission component 46, and thus control the position of the second moving plate 42. At the same time, the first transmission plate 45 changes according to the position of the second moving plate 42. Since the second driving component 4 and the third driving component 5 are connected by transmission, the position of the dispensing valve 22 mounted on the third driving component 5 in the Y-axis can be adjusted.

[0055] Specifically, the third drive assembly 5 includes a movable profile 51, a third movable plate 52, a second transmission plate 59, a third drive component 53, and a fourth drive component 54. Multiple dispensing valves 22 are installed on the movable profile 51. There are two of each of the second transmission plate 59 and the third movable plate 52. The two third movable plates 52 are installed on both sides of the first transmission plate 45 through the second transmission plate 59. The third drive component 53 and the fourth drive component 54 are respectively installed on the two third movable plates 52. The output end of the third drive component 53 is equipped with a first rotating wheel 55, and the output end of the fourth drive component 54 is equipped with a second rotating wheel 56. The first rotating wheel 55 and the second rotating wheel 56 are fitted with a synchronous belt 57. The movable profile 51 is connected to the synchronous belt 57 through the fixed buckle 58 installed on it.

[0056] In practical applications, the third moving plate 52 is connected to the first transmission plate 45, so that the third driving component 5 can change according to the position change of the second driving component 4. When it is necessary to adjust the position of the dispensing valve 22 in the Z-axis direction, the third driving component 53 and the fourth driving component 54 are started at the same time, driving the synchronous belt 57 to move, thereby causing the moving profile 51 to change in the Z-axis position, and thus changing the position of the dispensing valve 22 in the Z-axis.

[0057] Specifically, the connecting assembly 26 includes a first connecting pipe 261, a connecting pipe 262, and a connecting bracket 263. The first connecting pipe 261 is used to connect the pneumatic drive component 23 and the dispensing valve 22. The first connecting pipe 261 is located inside the connecting pipe 262. The connecting bracket 263 is fixedly installed at the bottom of the movable profile 51 to support the connecting pipe 262. Multiple connecting pipes 262 are arranged from the inside to the outside according to the distance between the corresponding dispensing valve 22 and the pneumatic drive component 23.

[0058] In this embodiment, there are four dispensing valves 22 and their corresponding components. The connecting pipe 262 of the dispensing valve 22 that is farthest from the pneumatic drive component 23 is located on the innermost side, and the connecting pipe 262 of the dispensing valve 22 that is closest to the pneumatic drive component 23 is located on the outermost side. When adjusting the position of the dispensing valve 22, the connecting pipe 262 of the dispensing valve 22 that is closest to the pneumatic drive component 23 is adjusted first to avoid misalignment of the position of the connecting pipe 262.

[0059] Specifically, the connecting and organizing component 26 also includes a second fixing frame 264, which is connected to the first transmission plate 45. The upper end of the second fixing frame 264 is used to install the pneumatic drive component 23. The side of the second fixing frame 264 is equipped with a stepped third fixing plate 265, which is used to fix one end of the connecting pipe 262. The first fixing frame 24 is provided with multiple fixing plates, and the corresponding dispensing valves 22 are installed on the movable profile 51. Each first fixing frame 24 is equipped with a fourth fixing plate 241, which is used to fix the other end of the connecting pipe 262, thereby enhancing the fixation of the position of the connecting pipe 262 and preventing the position of the connecting pipe 262 from being disordered during use, thus ensuring the smooth realization of its function of organizing the connecting line of the dispensing valve 22.

[0060] Specifically, a third guide rail 510 is installed on the movable profile 51, and a third slider 511 matching the third guide rail 511 is installed on each of the two third movable plates 52. A bending limiting plate 512 is installed on the end of the third guide rail 510 near the fourth driving member 54. A limiting seat 513 is installed on the third movable plate 52. The limiting seat 513 forms a limiting groove 514 matching the limiting plate 512. The dispensing valve 22 is installed on the side of the third guide rail 510 near the third driving member 53. The limiting plate 512 and the limiting seat 513 limit the movement position of the movable profile 51 to prevent derailment.

[0061] Specifically, the dispensing valve 22 is connected to a third transmission component 27, a fourth guide rail 28 is mounted on the first fixed frame 24, a fourth slider 29 that matches the fourth guide rail 28 is mounted on the third transmission component 27, a return spring 242 is mounted on the bottom of the first fixed frame 24, and a return plate 271 that matches the return spring 242 is mounted on the third transmission component 27. The arrangement of the return plate 271 and the return spring 242 can not only reset the position of the dispensing valve 22 head, but also limit its descent range, thereby improving safety.

[0062] In this embodiment, the dispensing machine is used in the production line for picture frame manufacturing. In practical applications, the movable profile 51 with the dispensing valve 22 is adjusted to a position parallel to the picture frame 100. The dispensing valve 22 is provided with four valves, each corresponding to one of the four picture frame 100 in the finished picture frame 200. When not in operation, the position of the dispensing valve 22 on the movable profile 51 can be changed by removing the screw 25 to accommodate different lengths of the picture frame 100. This allows for simple and quick dispensing of glue to picture frame 100 of different lengths, improving practicality.

[0063] It should be noted that the driving component in this embodiment is a motor, but it can also be replaced by a driving component with the same function. In addition, the guide rail and slider in this application both serve a guiding function.

[0064] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0065] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application are within the scope of protection of this application.
