Description

Technical Field

[0001] This invention belongs to the field of dispensing equipment technology, and particularly relates to an online 3D guided dispensing machine and its control method. Background Technology

[0002] With the wave of industrial intelligence, the electronics manufacturing industry has ushered in an opportunity for upgrading, but also faces many challenges. In the traditional dispensing production process, product inspection relies on manual labor, which not only places high demands on operators, but also results in inconsistent manual operation standards, leading to poor product quality stability.

[0003] As the requirements for dispensing continue to increase, dispensing paths have expanded from the traditional 2D mode to a 3D mode. Traditional 2D guidance cannot provide the Z coordinate of the dispensing path; it can only pre-input the Z coordinate or perform dispensing along a completely planar path.

[0004] Therefore, there is a need to provide an online 3D guided dispensing machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an online 3D guided dispensing machine, which aims to solve the problems of poor planar dispensing effect and inability to provide the Z coordinate of the dispensing path online in the prior art.

[0006] The present invention is implemented as follows: an online 3D guided dispensing machine, the online 3D guided dispensing machine includes a frame and a dual-channel Y-axis motion assembly, an X-axis motion assembly one, an X-axis motion assembly two, a Z-axis motion assembly one, a Z-axis motion assembly two, a 3D guiding assembly, a dispensing assembly, and a glue wiping and weighing assembly disposed on the frame.

[0007] The dual-channel Y-axis motion assembly is used to drive the product to be conveyed along the Y direction to pass sequentially through the 3D guide assembly and the dispensing assembly.

[0008] The X-axis motion component 1 spans the dual-channel Y-axis motion component 1, the Z-axis motion component 1 is disposed at the moving end of the X-axis motion component 1, and the 3D guide component is disposed at the moving end of the Z-axis motion component 1.

[0009] The second X-axis motion component spans the dual-channel Y-axis motion component, the second Z-axis motion component is disposed at the moving end of the second X-axis motion component, and the dispensing component is disposed at the moving end of the second Z-axis motion component.

[0010] The adhesive weighing component is located on the side of the dual-channel Y-axis motion component and is used to weigh the amount of adhesive dispensed and clean the dispensing head.

[0011] Another objective of this invention is to provide a control method for an online 3D guided dispensing machine, applicable to the online 3D guided dispensing machine as described in this invention, wherein the control method for the online 3D guided dispensing machine includes:

[0012] The required amount of adhesive is measured using a weighing device;

[0013] The dual-channel Y-axis motion assembly feeds the product into one channel and then conveys it through several conveying units to the 3D guide assembly for 3D inspection. At the same time, the dual-channel Y-axis motion assembly feeds the product into the other channel.

[0014] The product that has completed 3D inspection is transported by the active conveyor unit to the dispensing assembly for dispensing, while the product on the other channel of the dual-channel Y-axis motion assembly is transported to the 3D guide assembly for 3D inspection.

[0015] The product after the dispensing operation is completed is unloaded and output by the dual-channel Y-axis motion assembly. At the same time, the movable conveyor unit is reset, and the dispensing assembly is cleaned by the wiping assembly. The product after 3D inspection is conveyed to the dispensing assembly by another movable conveyor unit for dispensing operation.

[0016] Repeat the above steps to achieve dual-station online 3D guided dispensing.

[0017] The online 3D guided dispensing machine provided by this invention can acquire the three-dimensional coordinates of the dispensing path online through the setting of the 3D guiding component, thereby realizing the dispensing operation in three-dimensional coordinates; by setting the dual-channel Y-axis motion component, dual-station operation can be realized, so that the 3D guiding component and the dispensing component can work continuously, thereby improving production efficiency; in addition, this invention can realize online fully automated production of the production line and dispensing equipment, which requires no human intervention compared with the traditional offline operation, reducing labor and saving costs.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1-9 As shown, an online 3D guided dispensing machine provided in this embodiment of the invention includes a frame 1 and a dual-channel Y-axis motion assembly 7, an X-axis motion assembly 1 6, an X-axis motion assembly 2, a Z-axis motion assembly 1 56, a Z-axis motion assembly 26, a 3D guiding assembly 5, a dispensing assembly 4, and a glue wiping and weighing assembly 3 disposed on the frame 1.

[0031] The dual-channel Y-axis motion assembly 7 is used to drive the product to be conveyed along the Y direction to pass sequentially through the 3D guide assembly 5 and the dispensing assembly 4.

[0032] The X-axis motion component 6 spans the dual-channel Y-axis motion component 7, the Z-axis motion component 56 is disposed at the moving end of the X-axis motion component 6, and the 3D guide component 5 is disposed at the moving end of the Z-axis motion component 56.

[0033] The second X-axis motion component 2 spans the dual-channel Y-axis motion component 7, the second Z-axis motion component 26 is disposed at the moving end of the second X-axis motion component 2, and the dispensing component 4 is disposed at the moving end of the second Z-axis motion component 26.

[0034] The adhesive weighing component 3 is located on the side of the dual-channel Y-axis motion component 7 and is used for weighing the amount of adhesive dispensed and cleaning the dispensing point 31.

[0035] In this embodiment, reference Figure 1 The rack 1 includes an upper rack and a lower rack. The upper rack is equipped with an installation platform on which all components are installed. The four sides and top of the installation platform are enclosed, and windows or observation windows can be opened on the enclosed. The lower rack is equipped with a cabinet door, and control components or commonly used tools can be installed inside the cabinet.

[0036] In this embodiment, the dual-channel Y-axis motion assembly 7 is provided with two conveying channels. The two conveying channels can work independently. Preferably, the conveying actions of the two conveying channels are staggered, so that the time interval between actions can be used to make the 3D guiding assembly 5 and the dispensing assembly 4 work continuously without interruption, thereby improving dispensing efficiency.

[0037] In this embodiment, the 3D guide component 5 can collect the three-dimensional dispensing path of the product and transmit the collected path to the dispensing component 4, enabling the dispensing component 4 to perform three-dimensional online dispensing. Here, "online" means that the product's dispensing path coordinates do not need to be pre-inputted, and the dispensing path can be collected online in real time. Furthermore, the dispensing path collected by the 3D guide component 5 can be used to calculate the total amount of glue required and the amount of glue required for each step of the dispensing component 4, thereby achieving precise dispensing control.

[0038] In this embodiment, a glue-wiping and weighing component 3 is also provided to clean the glue dispensing point 31. On the one hand, this prevents the glue dispensing point 31 from becoming clogged. On the other hand, cleaning after dispensing can reduce the residue of glue at the glue dispensing point 31 and prevent the measured amount from not matching the actual amount of glue dispensed.

[0079] The weighing device 301 is mounted on the mounting plate 302 and is used for weighing the glue.

[0080] In this embodiment, the take-up roller and the unloading roller of the adhesive application assembly rotate, thereby moving the adhesive tape to wipe and clean the adhesive application point 31, ensuring the cleanliness of the adhesive application point 31.

[0081] In this embodiment, a weighing device 301 is also provided. The weighing device 301 can control the amount of adhesive applied to each product or each dispensing path, thereby making the dispensing more uniform. Optionally, in this embodiment, the weighing device 301 is connected to the dispensing device 25 via a flexible hose, and the weighed adhesive is transported to the dispensing device 25 through a pipe; since there is already adhesive in the pipe, the transport process will not reduce the amount of adhesive.
