Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically relating to a fully automatic 3D glue printing device. Background Technology

[0002] Traditional 3D printing technologies, such as fused deposition modeling (FDM) and stereolithography (SLA), have been widely used, but they typically use specific filaments or photosensitive resins as molding materials, resulting in high material costs, limited material variety, and complex post-processing. On the other hand, dispensing machines are widely used in electronic packaging, sealing, and other fields, but their movements are mostly two-dimensional or simple three-dimensional paths, making it difficult to quickly and accurately construct complex three-dimensional solid structures.

[0003] Existing technologies include some devices that combine dispensing with three-dimensional motion, but they typically suffer from the following drawbacks:

[0004] Low level of automation: Frequent manual replenishment of materials or intervention in the printing process is required.

[0005] Limited functionality: It lacks integrated control over the printing environment (such as temperature and curing) and has difficulty handling adhesive materials with various properties. Utility Model Content

However, this utility model may also be implemented in other ways different from those described herein.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0032] Please see the appendix Figs. 1 to 3As shown, this utility model provides a fully automatic 3D adhesive printing device, including: a motion system 1, used to provide precise relative motion in three dimensions; a material feeding and storage system 2, installed on the top of the support of the motion system 1, used to store, transport and precisely control the extrusion of adhesive material; a printing nozzle system 3, installed on the motion system 1, used to receive material from the material feeding and storage system 2 and perform precise coating; and a control system 5, electrically connected to the motion system 1, the material feeding and storage system 2 and the printing nozzle system 3, used to control the coordinated operation of each system. The motion system 1 is an XYZ three-axis Cartesian coordinate motion platform, including an X-axis motion module, a Y-axis motion module and a Z-axis motion module. The printing nozzle system 3 is installed on the X-axis motion module and the Z-axis motion module, and the printing platform is installed on the Y-axis motion module.

[0033] In this application, when product printing is required, the necessary adhesive is first filled into the storage tank 21, and the temperature and pressure parameters are set. The product data is input into the control system 7 to generate the printing path. When printing begins, the control system 7 starts the equipment, and the motion system 1 drives the printing platform and the print head 5 to move to the starting point. During 3D printing, the extrusion pump 22 draws material from the storage tank 21 and pumps it into the print head system 3, where it is ejected layer by layer. The extruded adhesive lines are then irradiated by the curing system 4, rapidly changing from a liquid to a solid state. The motion system 1 moves along the predetermined path, and the extrusion and curing processes are carried out simultaneously, layer by layer, ultimately forming a three-dimensional entity. The vision system 6 monitors and calibrates the entire process. After printing is completed, the product can be removed from the printing platform, thus completing the printing process.

[0034] The feeding and storage system 2 includes a storage tank 21 and an extrusion pump 22. The storage tank 21 and the extrusion pump 22 are connected by a connecting pipe 23, and the extrusion pump 22 is connected to the printing nozzle system 3 by a connecting pipe 24.

[0035] In this application, the main working state of the feeding and storage system 2 is as follows: the extrusion pump 22 is connected to the storage tank 21 through the connecting pipe 23, draws in the adhesive material inside, and then pumps the adhesive into the printing nozzle system 3 through the connection between the connecting pipe 24 and the printing nozzle system 3. The adhesive is then ejected from the printing nozzle system 3 for printing. The specific structure of the extrusion pump 22 is a cylindrical structure with a spiral rod inside and a drive device connected to one end outside. The control system 5 is electrically connected to the drive device in the extrusion pump 22. The drive device drives the spiral rod to rotate, draws out the adhesive, and pumps it into the printing nozzle system 3 for printing.

[0036] A heating plate 25 is installed below the storage box 21. The heating plate 25 is used to control the viscosity of the adhesive. The control system 5 is electrically connected to the heating plate 25.

[0037] Depending on the properties of the adhesive used, different heating temperatures can be selected to adjust the viscosity of the adhesive, making it easier to transport.

[0038] A curing system 4 is installed on one side of the print head system 3. The curing system 4 is an ultraviolet curing lamp assembly or a hot air curing device.

[0039] The curing system 4 can be mounted on an adjustable bracket (not shown in the figure) and adjusted according to different usage requirements to ensure that the curing beam can be focused on the position where the glue line is just extruded, so as to achieve instant curing. The curing system 4 moves together with the printing nozzle system 3, and cures while printing. It uses the lower layer material to support the upper layer material to prevent deformation.

[0040] On the other side of the print head system 3, a vision system 6 is installed. The vision system 6 is used to monitor the printing position in real time. The vision system 6 is electrically connected to the control system 5.

[0041] In this application, the vision system 6 (such as a miniature high-definition camera) is installed on the other side of the print head system 3, with its optical axis aligned with the nozzle tip of the print head system 3, and can capture the position of the print point in real time.

[0042] The control system 5 includes a computing unit, a vision processing unit, and a control unit. The vision processing unit performs real-time compensation on the motion path based on the image information fed back by the vision system 6, thereby achieving closed-loop control.

[0043] The control and connection between the control system 5 and the motion system 1, the feeding and storage system 2, the printing nozzle system 3, the curing system 4, and the vision system 6 are all existing technologies and will not be described in detail here.

[0044] The working principle of this utility is as follows:

[0045] Preparation: Fill the required adhesive into the storage tank 21, and set the temperature and pressure parameters. Input the product data into the control system 5 and generate the printing path.

[0046] Start printing: Control system 5 starts the equipment, and motion system 1 drives the printing platform and print head 5 to move to the starting point.

[0047] Material extrusion: The extrusion pump 22 draws material from the storage tank 21 and pumps it into the print head system 3, where it is ejected and stacked layer by layer.

[0048] Simultaneous curing: The extruded adhesive line is immediately irradiated by the curing system 4, and quickly changes from liquid to solid.

[0049] Layer-by-layer stacking: Motion system 1 moves along a predetermined path, with extrusion and curing processes occurring simultaneously, stacking layer by layer to ultimately form a three-dimensional solid. Vision system 6 monitors and calibrates the entire process.

[0050] Post-printing process: Once printing is complete, simply remove the product from the printing platform to finish printing.

[0051] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
