The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0019] One embodiment of this utility model is as follows: Figure 1 , 2 As shown, this three-station high-efficiency five-axis linkage dispensing system is used to improve positioning accuracy and dispensing efficiency. It includes a frame 1, a dispensing platform 2, a vision positioning module 3, and a dispensing module 4. There are three dispensing platforms 2, which are arranged in parallel on the frame 1. A gantry frame 11 is mounted on the frame 1 and is located within the stroke range of the dispensing platform 2. A moving unit 12 is provided on each side of the gantry frame 11. There are three visual positioning modules 3, each of which is set on one of the moving units 12. The three visual positioning modules 3 are respectively set on the three dispensing platforms 2. The dispensing module 4 is mounted on another moving unit 12 to guide and dispense adhesive onto different workpieces or different parts of the same workpiece.

[0020] The three-station high-efficiency five-axis linkage dispensing system in this embodiment is suitable for high-efficiency dispensing equipment. It is a high-efficiency dispensing machine with three dispensing stations and a separate vision module and dispensing module 4. Through the parallel operation of three independent dispensing platforms 2 and the separate design of vision and dispensing valve, it achieves efficient and precise dispensing operations. First, three identical or different workpieces are placed in the workpiece fixtures 24 on the three dispensing platforms 2 respectively. The dispensing platforms 2 move their respective workpieces to the corresponding vision positioning module 3 station, so that the workpieces can move precisely in three-dimensional space to cooperate with the vision positioning module 3 to complete the guidance and obtain dispensing data. After the guidance is completed, the workpieces are moved to the dispensing position of the dispensing module 4 for dispensing, thereby effectively improving dispensing efficiency.

[0021] In this embodiment, as Figure 1 , 3As shown, the dispensing platform 2 includes a support base 21, an adapter base 22, a carrier base 23, a workpiece clamp 24, and a first power assembly 25. The first power assembly 25 is mounted on the frame 1. The support base 21 is mounted on the working end of the first power assembly 25. The adapter base 22 is rotatably mounted on the support base 21. The carrier base 23 is rotatably mounted on the adapter base 22. The workpiece clamp 24 is detachably mounted on the carrier base 23.

[0022] Specifically, the three dispensing platforms 2 are arranged in parallel on the frame 1, so that the workpiece clamp 24 is moved in the X direction by the first power component 25. It is first positioned by the vision positioning module 3, and then the dispensing module 4 completes the dispensing. The workpiece clamp 24 is detachably installed on the support base 23 by snap-fit ​​or / and screw-fit, so as to facilitate quick replacement and adjustment of different workpiece shapes and sizes, and improve the versatility of the equipment.

[0023] In this embodiment, as Figure 1 , 2 As shown, both of the moving units 12 are arranged along the length of the gantry frame 11 and have the same structure as the first power assembly 25.

[0024] Specifically, the first power component 25 is a linear motor module or a linear slide. In this embodiment, the power source selected is a cylinder or a motor. The selected cylinder, motor and other components are all existing components. The first power component 25 drives the workpiece fixture 24 to move in the X direction, one of the moving units 12 drives the vision positioning module 3 to move in the Y direction, and another moving unit 12 drives the dispensing module 4 to move in the Y direction.

[0025] In this embodiment, as Figure 3 As shown, the support base 21 has symmetrical support shaft seats 28 on both sides. A transition shaft is rotatably arranged inside the support shaft seat 28, and a transition shaft seat 29 is arranged on the transition shaft. The two opposite sides of the transition seat 22 are respectively connected to the two transition shaft seats 29, so that the transition seat 22 is rotatably connected to the support base 21.

[0026] Specifically, a support shaft seat 28 is provided on each of the left and right sides of the upper part of the support base 21. A transition shaft passes through the support shaft seat 28. A transition shaft seat 29 is provided on the inner side of the two transition shafts. The two transition shaft seats 29 are respectively connected to the left and right sides of the transition base 22 so that the transition base 22 can rotate along the connecting shaft on the support base 21, thereby realizing the rotation of the A-axis of the workpiece fixture 24.

[0027] In this embodiment, as Figure 3As shown, a second power assembly 26 is provided on one side of the support base 21. The working end of the second power assembly 26 is connected to the adapter shaft to drive the adapter base 22 to rotate.

[0028] Specifically, a second power component 26 is provided on the left side of the support base 21. The second power component 26 is a servo motor. A harmonic reducer is added to the working end of the servo motor to drive the adapter base 22 to rotate along the A-axis, thereby realizing the rotation of the workpiece fixture 24 along the A-axis.

[0029] In this embodiment, as Figure 3 As shown, the support seat 23 is vertically mounted on the adapter seat 22. A third power component 27 is provided on the lower side of the adapter seat 22. The working end of the third power component 27 is connected to the support seat 23 to drive the support seat 23 to rotate.

[0030] Specifically, the third power component 27 is a DD rotary motor, which drives the support 23 to rotate along the C-axis. Through the cooperation of the three power sources—the first power component 25, the second power component 26, and the third power component 27—the dispensing platform 2 has X, A, and C-axis motion, enabling precise movement of the workpiece in three-dimensional space. The first power component 25 of the dispensing platform 2 uses a high-precision linear guide rail and a linear motor as the driving force transmission. The A-axis adopts a servo motor and harmonic reducer structure, and the C-axis is directly driven by a DD motor. The three degrees of freedom are independently controlled, ensuring smooth movement and accurate positioning.

[0031] In this embodiment, as Figure 4 As shown, the visual positioning module 3 includes a positioning base plate 31, a positioning drive component 32, a positioning mounting plate 33, and a first camera 35. The positioning base plate 31 is disposed on the working end of the moving unit 12. The positioning mounting plate 33 is slidably disposed on one side of the positioning base plate 31. The positioning drive component 32 is disposed on the upper side of the positioning base plate 31, and its working end is connected to the positioning mounting plate 33. The first camera 35 is disposed on the positioning mounting plate 33.

[0032] Specifically, all three vision positioning modules 3 are mounted on the moving unit 12 on the left side of the gantry 11. The positioning drive component 32 drives the camera to move in the Z direction to obtain data of the workpiece dispensing surface in the Z direction. Through the cooperation of the moving unit 12 and the first power component 25 of the corresponding dispensing platform 2, data of the workpiece dispensing surface in the x and y directions are obtained.

[0033] In this embodiment, as Figure 4 As shown, the positioning base plate 31 has a positioning guide rail 34 arranged along its own height direction on the side close to the positioning mounting plate 33, and is slidably connected to the positioning mounting plate 33 through the positioning guide rail 34.

[0034] Specifically, the positioning drive assembly 32 consists of a Z-axis servo motor and a precision lead screw. The lead screw drives the positioning mounting plate 33 to move along the positioning guide rail 34, so that the camera moves in the Z direction to facilitate the detection of data on the adhesive surface of the workpiece.

[0035] In this embodiment, as Figure 4 As shown, a second camera 36 is disposed on the positioning mounting plate 33 on the side of the first camera 35.

[0036] Specifically, one vision positioning module 3 corresponds to one dispensing platform 2 and is separate from the dispensing valve. Vision positioning and dispensing operations do not interfere with each other, which limits the improvement of positioning accuracy and dispensing efficiency.

[0037] Specifically, the visual positioning module 3 consists of a high-resolution industrial camera, a lens, a light source, and image processing software. The camera is mounted on a bracket consisting of a positioning base plate 31 and a positioning mounting plate 33, and is separate from the dispensing valve of the dispensing module 4, thus avoiding the impact of vibration and glue splashing during the dispensing process on the camera imaging. The lens is a telecentric lens or a high-magnification zoom lens to meet the imaging requirements of workpieces of different sizes. The light source uses a ring LED light source or coaxial light to provide uniform, shadow-free illumination and improve image quality. The image processing software has powerful algorithm functions and can quickly identify the mark points, edges, or holes of the workpiece to achieve high-precision positioning with a positioning accuracy of ±0.01mm.

[0038] In this embodiment, as Figure 2 , 5 As shown, the dispensing module 4 includes a dispensing connecting plate 41, a dispensing mounting plate 43, a dispensing driving assembly 42, and a dispensing assembly 44. A guide rail 45 is provided on the dispensing mounting plate 43 and is slidably connected to the dispensing connecting plate 41 through the guide rail 45. The dispensing driving assembly 42 is disposed on the upper side of the dispensing connecting plate 41, and its working end is connected to the dispensing mounting plate 43. The dispensing assembly 44 is disposed on the dispensing mounting plate 43.

[0039] Specifically, the dispensing module 4 is mounted on the moving unit 12 on the right side of the gantry frame 11. Through the cooperation of the moving unit 12, the first power component 25 of the corresponding dispensing platform 2, and the dispensing drive component 42, the dispensing component 44 can move in three directions (XYZ) to complete the dispensing work.

[0040] Specifically, the dispensing drive assembly 42 consists of a Z-axis servo motor and a precision lead screw. The lead screw drives the dispensing assembly 44 to move up and down along the guide rail 45, and cooperates with the moving unit 12 to drive the dispensing assembly 44 to move in the Y and Z directions.

[0041] Specifically, the dispensing assembly 44 includes a dispensing valve, a glue tube, and a pressure control device. The dispensing valve is selected from pneumatic valves, screw valves, or piezoelectric valves based on the characteristics of the glue (such as viscosity and curing method). Pneumatic valves are suitable for low-viscosity glues, controlling the dispensing volume through air pressure. Screw valves are suitable for high-viscosity glues, precisely measuring the dispensing volume through screw rotation. Piezoelectric valves can achieve micro-volume (0.001mg) dispensing, suitable for high-precision dispensing requirements. The pressure control device monitors and adjusts the glue delivery pressure in real time, compensating for glue viscosity fluctuations caused by changes in ambient temperature, keeping glue volume fluctuations within ±2%. The glue tank is equipped with a heating device and a stirring device, suitable for hot melt glues and other glues requiring heating and stirring. The glue tank is also equipped with a glue level sensor to monitor the remaining glue level in real time, issuing an alarm signal promptly when the glue is insufficient.

[0042] Specifically, the dispensing assembly 44 is also equipped with a 3D line laser sensor, which can achieve micron-level precision to accurately measure the width, height, and contour of the adhesive, meeting tolerance requirements (such as height ±0.05mm and width ±0.15mm). Through point cloud data analysis, adhesive path defects (such as insufficient adhesive, broken adhesive, unevenness, and collapsed adhesive) can be identified to ensure dispensing quality.

[0043] In this embodiment, the three-station high-efficiency five-axis linkage dispensing system operates independently and in parallel, enabling simultaneous dispensing of multiple workpieces and significantly shortening the production cycle. For example, in the dispensing of mobile phone camera modules, the production efficiency can be increased by more than three times compared to traditional single-platform dispensing machines.

[0044] The separate design of the vision positioning system and dispensing valve avoids mutual interference and improves positioning and dispensing accuracy. The high-precision motion control system and dispensing valve system further ensure the accuracy and consistency of dispensing, with the glue line width stable at 0.2-0.5mm and glue volume fluctuation controlled within ±2%.

[0045] The interchangeable workpiece clamps 24 and various types of dispensing valves enable the equipment to adapt to workpieces of different shapes, sizes and materials as well as adhesives with different properties, improving the equipment's versatility and flexibility.

[0046] Independent vision positioning and glue supply systems reduce the impact of external factors on the dispensing process, improving equipment stability and reliability. Simultaneously, the equipment possesses comprehensive fault diagnosis and alarm functions, facilitating timely troubleshooting and ensuring continuous production.

[0047] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
