A double-gantry asynchronous double-spray valve dispensing machine

Abstract

This utility model discloses a dual-gantry asynchronous dual-jet valve dispensing machine, which aims to solve the problem of low production efficiency caused by the single-gantry structure of existing dispensing machines, which can only dispense one circuit board at a time. The dispensing machine includes a base with two gantry robots mounted on it on both sides. One side of the base has an X-axis moving component for driving the gantry robots in the X direction. Each gantry robot includes a gantry frame, a robotic arm, a frame, a positioning camera, and a dispensing valve. This utility model uses the X-axis, Y-axis, and Z-axis moving components to drive the positioning camera and dispensing valve to move left-right, forward-backward, and up-down. The positioning camera takes a picture for positioning before dispensing. Furthermore, due to the dual-gantry structure, the dispensing valve can dispense two circuit boards simultaneously, greatly improving the working efficiency of the dispensing machine.

Description

Technical Field

[0001] This utility model belongs to the field of dispensing machine technology, specifically relating to a double gantry asynchronous double spray valve dispensing machine. Background Technology

[0002] In the modern electronics manufacturing industry, flexible printed circuit boards (FPCs) are widely used in various electronic products such as mobile phones, laptops, and digital cameras due to their advantages such as high wiring density, light weight, thinness, and good flexibility. As electronic products continue to evolve towards miniaturization, lightweighting, and multifunctionality, the demand for FPCs continues to rise, placing increasingly stringent requirements on their processing precision and production efficiency. Adhesive dispensing, as a crucial step in FPC processing, plays a vital role. During circuit board assembly, adhesive dispensing secures and protects electronic components, enhancing product reliability.

[0003] Traditional dispensing machines use a single gantry structure, which can only dispense glue to one circuit board at a time. Only after dispensing one circuit board can the next one be processed. This results in low production efficiency, making it difficult to meet the needs of large-scale production. Furthermore, it is not convenient to accurately adjust the position of the spray valve, which can easily lead to deviations and affect the dispensing effect. Utility Model Content

[0004] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double gantry asynchronous double spray valve dispensing machine. This dispensing machine aims to solve the problem that the existing dispensing machines adopt a single gantry structure, which can only dispense glue to one circuit board at a time, resulting in low production efficiency.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a dual-gantry asynchronous dual-jet valve dispensing machine. The dispensing machine includes a base, on which two gantry robots are mounted. The two gantry robots are installed on both sides of the base. One side of the base is provided with an X-axis moving component for driving the gantry robots to move in the X direction. The gantry robots include a gantry frame, a robotic arm, a frame, a positioning camera, and a dispensing valve. A Y-axis moving component for driving the robotic arm to move in the Y-axis direction is installed on the gantry frame, and a Z-axis moving component for driving the frame to move in the Z-axis direction is installed on the robotic arm. The positioning camera and the dispensing valve are mounted on the frame, and the left and right robotic arms are mounted on the side of the two gantry frames that are close to each other.

[0006] Preferably, the dispensing valve is an asynchronous dual-spray valve, and a conveyor track is provided on the machine base.

[0007] Furthermore, a protective cover is fixedly mounted on the base. Openings are provided on both sides of the protective cover, and the openings correspond to the positions of the conveyor rails. A controller and two transparent observation windows are installed on the protective cover. The two X-axis moving components, the Y-axis moving component, the Z-axis moving component, the positioning camera, and the dispensing valve are all electrically connected to the two controllers.

[0008] Furthermore, the dispensing valve includes a main valve fixedly mounted to the frame and a secondary valve slidably mounted to the frame. A first moving component for driving the secondary valve to move in the Y-axis direction is mounted on the other side of the frame, and a second moving component for driving the secondary valve and the first moving component to move synchronously in the X-axis direction is also mounted on the other side of the frame.

[0009] Furthermore, the X-axis moving assembly includes two first drive rails fixedly connected to the base and electric sliders fixedly connected to both ends of the gantry, with the electric sliders slidably connected to the first drive rails.

[0010] Furthermore, two protective plates are fixedly connected to one side of the base, and two first drive rails are fixedly connected to the front and rear sides of the upper surface of the base. One first drive rail and one electric slider are located between the two protective plates.

[0011] Furthermore, the Y-axis movement assembly includes a second drive rail fixedly connected to the gantry and a second electric slider fixedly connected to one side of the robotic arm, the second electric slider being slidably connected to the second drive rail.

[0012] Furthermore, the Z-axis movement assembly includes a drive motor fixedly connected to the robotic arm and a movable block fixedly connected to the frame. The frame is slidably connected to the robotic arm, and a lead screw is fixedly connected to the output end of the drive motor. The other end of the lead screw is threadedly connected to the movable block.

[0013] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets up two independent main valves and auxiliary valves. The main valve is fixedly set, and the auxiliary valve can be adjusted in four directions (front, back, left, and right) by the first and second moving components. When facing asymmetrical dispensing tasks, the position of the auxiliary valve can be precisely adjusted, so that the dual spray valve can dispense glue to different positions, avoid deviation, and improve the dispensing effect of the product. 2. This utility model places the product on a conveyor track, which carries the product into two dispensing stations of the dispensing machine. Then, the positioning sensor pops up to stop the product. The positioning camera and dispensing valve move left and right, forward and backward, and up and down through the X-axis, Y-axis, and Z-axis moving components. After the positioning camera takes a picture and positions the product, the dispensing valve performs a flexible dispensing action. Furthermore, due to the adoption of a double gantry structure, the two gantry robots can be controlled independently. The dispensing valves on the gantry robots can simultaneously perform dispensing operations on two circuit boards without interference, greatly improving the working efficiency of the dispensing machine.

[0021] This specific embodiment is a dual-gantry asynchronous dual-spray valve dispensing machine, and its structural schematic diagram is shown below. Figures 1-6As shown, the dispensing machine includes a base 1, on which two gantry robots 4 are mounted. The gantry robots 4 are located on the upper side of the base 1. An X-axis moving assembly 5 for driving the gantry robots 4 to move in the X direction is mounted on one side of the base 1. The gantry robots 4 include a gantry frame 6, a robotic arm 7, a frame 8, a positioning camera 9, and a dispensing valve 10. A Y-axis moving assembly 11 for driving the robotic arm 7 to move in the Y-axis direction is mounted on the gantry frame 6. A Z-axis moving assembly 12 for driving the frame 8 to move in the Z-axis direction is mounted on the robotic arm 7. The positioning camera 9 and the dispensing valve 10 are mounted on the frame 8. The left and right robotic arms 7 are mounted on the side of the two gantry frames 6 that are close to each other.

[0022] like Figure 1 and Figure 6 As shown: In this embodiment, a conveyor rail 2 is provided on the base 1 for conveying products. Two gantry robots 4 are installed on both sides of the conveyor rail 2. A protective cover 13 is fixedly fitted on the base 1. Openings 14 are provided on both sides of the protective cover 13, and the openings 14 correspond to the positions of the conveyor rail 2. A controller 15 and two transparent observation windows 16 are installed on the protective cover 13. Two X-axis moving components 5, Y-axis moving components 11, Z-axis moving components 12, positioning camera 9, and dispensing valve 10 are all electrically connected to the two controllers 15. The controllers 15 can control the operation of the X-axis moving components 5, Y-axis moving components 11, Z-axis moving components 12, positioning camera 9, and dispensing valve 10, so that the gantry robots 4 can work independently. The dispensing process can be observed through the transparent observation windows 16, which is very convenient. When the conveyor track 2 carries the product into the dispensing station of the dispensing machine, it enters from the left opening 14 without affecting the movement of the product. After dispensing is completed, it flows out from the right opening 14.

[0023] like Figure 1 and Figure 5 As shown: In this embodiment, the dispensing valve 10 is an asynchronous dual-jet valve. The dispensing valve 10 includes a main valve 1002 fixedly installed with the frame 8 and a secondary valve 1003 slidably installed with the frame 8. A first moving component for driving the secondary valve 1003 to move in the Y-axis direction is installed on the other side of the frame 8. A second moving component for driving the secondary valve and the first moving component to move synchronously in the X-axis direction is also installed on the other side of the frame 8. By setting two independent main valves 1002 and secondary valves 1003, and with the main valve 1002 fixedly installed, the secondary valve 1003 can be adjusted in four directions (front, back, left, and right) by the first and second moving components. When facing asymmetrical dispensing tasks, the position of the secondary valve 1003 can be precisely adjusted, thereby enabling the dual-jet valve to dispense at different positions, avoiding deviations, and improving the dispensing effect of the product.

[0024] like Figure 1 and Figure 5 As shown: In this embodiment, the X-axis moving assembly 5 includes two first drive rails 501 fixedly connected to the base 1 and electric sliders 502 fixedly connected to both ends of the gantry 6. The electric sliders 502 are slidably connected to the first drive rails 501. Two first motors are installed inside the first drive rails 501. When the first motor rotates forward, it can make the electric sliders 502 slide to the left on the first drive rails 501 through the screw. When the first motor rotates in reverse, it can make the electric sliders 502 slide to the right on the first drive rails 501 through the screw. Thus, the two first motors can adjust the positions of the left and right positioning cameras 9 and the dispensing valve 10 left and right.

[0025] like Figure 1 and Figure 2 As shown: In this embodiment, two protective plates 3 are fixedly connected to one side of the base 1, and two first drive rails 501 are fixedly connected to the front and rear sides of the upper surface of the base 1. One first drive rail 501 and one electric slider 502 are located between the two protective plates 3. The main valve 1002 and the auxiliary valve 1003 can be moved to the upper side of the two protective plates 3. The two protective plates 3 protect the first drive rail 501 and the first electric slider 502 on the front side, prevent contamination, and improve service life.

[0026] like Figure 2 and Figure 4 As shown: In this embodiment, the Y-axis moving assembly 11 includes a second drive rail 1101 fixedly connected to the gantry 6 and a second electric slider 1102 fixedly connected to one side of the robotic arm 7. The second electric slider 1102 is slidably connected to the second drive rail 1101. A second motor is installed inside the second drive rail 1101. When the second motor rotates forward, it can cause the second electric slider 1102 to slide forward on the second drive rail 1101 through a screw. When the second motor rotates in reverse, it can cause the second electric slider 1102 to slide backward on the second drive rail 1101 through a screw, thereby adjusting the position of the positioning camera 9 and the dispensing valve 10.

[0027] like Figure 1 and Figure 5As shown: In this embodiment, the Z-axis moving assembly 12 includes a drive motor 1201 fixedly connected to the robotic arm 7 and a movable block 1202 fixedly connected to the frame 8. The frame 8 is slidably connected to the robotic arm 7. A lead screw 1203 is fixedly connected to the output end of the drive motor 1201, and the other end of the lead screw 1203 is threadedly connected to the movable block 1202. When the drive motor 1201 rotates forward, it can move the movable block 1202 through the lead screw 1203. Since the frame 8 is slidably connected to the robotic arm 7, the movable block 1202 will move upward along the axial direction of the lead screw 1203. When the drive motor 1201 rotates in reverse, the movable block 1202 drives the frame 8 to move downward, thereby adjusting the position of the positioning camera 9 and the dispensing valve 10.

[0028] Working principle: By placing the product on the conveyor track 2, the conveyor track 2 flows the product into the two dispensing stations of the dispensing machine. Then, the positioning sensor pops up to stop the product. Then, the positioning camera 9 and the dispensing valve 10 move left and right, forward and backward, and up and down through the X-axis moving component 5, Y-axis moving component 11, and Z-axis moving component 12. After the positioning camera 9 takes a picture and positions the product, the dispensing valve 10 performs a flexible dispensing action. Due to the adoption of a double gantry structure, the two gantry robots 4 can be controlled independently. The dispensing valve 10 on the gantry robot 4 can perform dispensing operations on two circuit boards at the same time without interference, which greatly improves the working efficiency of the dispensing machine. After dispensing is completed, the product is released and the conveyor track 2 flows to the next station.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
